Plug & play system compatible with company’s skid-steer, compact tracked and all-wheel steer loaders
Bobcat has announced a new remote control system for its compact loaders, which allows operators to leave their seat in the cab and control their Bobcat loader remotely.
The remote control is compatible with Bobcat’s skid-steer, compact track and all-wheel steer loader models equipped with the company’s selectable joystick controls.
The company said that this makes it the first manufacturer to introduce a remote control system as original plug & play equipment, rather than as an add-on development from a third party. The new system will be commercially available later this year.
According to Bobcat, remote control solutions have proved their qualities and abilities to save lives in the toughest environments all around the world by providing service during disasters like floods, forest fires, mud or rockslides, and in other places where operators can be subjected to dangerous situations.
“We first presented our remote control prototype at Bobcat Demo Days with excellent feedback from our customers, then subjected it to further improvements, testing and licensing, before finally introducing it as an easy plug & play solution for existing machines for commercial launch,” said Jiri Karmazin, loaders product manager, Doosan Bobcat EMEA.
“The remote control system can be used in many applications with the focus on limitless visibility, the ability to communicate with the surroundings without the need to be present in the cab, comfort enhancement for applications with noise, vibration and harshness, or even in dangerous areas. This was the voice of our customers and the issues we observed on most job-sites.”
The system is an easily portable and industrial radio remote control solution that can be mounted and dismounted on machines in minutes.


Global Optical Module Market: Towards High Speed 400G Optical Modules
Feb. 23, 2023
The demand for higher Ethernet speeds, coupled with the popularity of cloud computing, IoT and virtual data centres, has driven a dramatic growth in the global optical transceiver market to capture the leading broadband network capacity. While the last few decades have witnessed the mass adoption of 1G, 10/25G to 40/100G optical transceivers, higher speed 200G and 400G transceivers are only just emerging. Sales of high-speed optical components have grown steadily and are expected to continue to grow in the coming years.
10G, 25G, 40G and 100G: widespread adoption in data centres
Data centres are undergoing a major transformation as networks become faster and virtualisation becomes the norm. Trends emerging in the industry mark a migration to higher-speed transceivers and better services. With the widespread use of 10/25Gbps, 40Gbps and 100Gbps, high bandwidth transceivers such as 200G and 400G are also becoming more popular.
10G transceivers: moving to the edge
Originally offered in the early 2000s, 10G optics have matured and are now becoming commonplace in data centres. Essentially, 10G Ethernet stacks to 40G and 100G at the access layer, following a 10G-40G-100G upgrade path, but this quadruples cabling complexity, power consumption and overall cost. This is exacerbated when aggregating to 100G (10 x 10G) interfaces.
25G transceivers: paving the way for 100G
Thus, a game changer emerges: 25GbE allows for better economics and efficiency. The SFP+-compatible SFP28 optical transceiver is designed for 25G Ethernet, delivering 2.5x the speed per lane with lower power consumption. With 25GbE smoothing the path to 100G at a lower cost, lower power and less cabling complexity, some users are even planning to skip 10G and deploy 25G Ethernet directly for better scaling to 50G and 100G.
40G transceivers: affordable and suitable for large-scale deployments
It is clear that 10GbE is no longer sufficient for data centres handling large-scale applications, so 40G is designed to alleviate bottlenecks at the access layer. 40G is extremely expensive initially, making it difficult to get 40G technology off the ground. Fortunately, we have seen a significant reduction in the cost of 40G transceivers over the last few years, which has accelerated their adoption in aggregated links or access links to servers.
100G transceivers: accelerating growth in the data centre
100G is now the fastest widely adopted Ethernet connection and continues to grow. And the optical module market bodes well for continued low prices for 100G QSFP28 modules, making the cost gap between 40G and 100G even smaller. In addition, 25G servers and 100G switches are becoming commonplace in most hyper scale data centres, replacing the previous 10G servers and 40G switches. Vendors of 100G QSFP28 transceivers will continue to evolve their products and push the limits of their versatility.
200G and 400G transceivers - new connection speeds hit data centres
Another foreseeable trend in the interconnect market is the phasing out of low-speed transceivers in the network core and data centres. Hence comes the major shift from 10G/25G/40/100G to 200G and 400G transceivers: next-generation 200G and 400GbE deployments in data centres started in 2018 and are now becoming mainstream. Overall, the optical transceiver market is moving towards higher speeds, lower power consumption and smaller sizes. Let's take a look at these future-proof 200G and 400G optical transceivers.
200G SFP-DD transceivers: short for Small Form-factor Pluggable Double Density, doubling SFP bandwidth and supporting fast line rates while maintaining SFP backward compatibility.
400G QSFP-DD Transceiver: or Quad Small Form Factor Pluggable Double Density Transceiver, as defined by the QSFP-DD MSA group, plans to double the density of the QSFP28 modules and assign eight channels to operate at speeds up to 25 Gbps or 50 Gbps, so they will support optical transmission at 200 Gbps or 400 Gbps.
DACs and AOCs: low cost spurs popularity
With their inherent benefits of enhanced signal integrity and superior flexibility, DACs (Direct Connect Copper) and AOCs (Active Optical Cables) have become the preferred and cost-effective interconnects for 10G, 25G, 40G and 100G high-speed links for all applications in hyperscale and enterprise, and potentially for 200G and 400G as well. 400G DACs and 400G AOCs are witnessing The data interconnect market growing tremendously and there is no doubt that sales will continue to soar in the coming years.
According to a recent study, the global 400G optical transceiver market is expected to continue to grow in popularity and sales over the next few years, eventually reaching $22.6 billion by 2023. Global Internet adoption, online commerce, streaming video, social networking, cloud services and software as a service (SaaS), as well as the availability and cost-effectiveness of 400G transceivers all play a role in this business networking trend. So, stay tuned and embrace the significant opportunities that lie ahead for the optical transceiver market.

Ever since the launch of iPhone back in 2007, AT&T users have been complaining regarding poor network service in San Francisco. After six long years, the U.S. carrier has added support for several new cell sites in the city that’ll most probably be enough to iron out the kinks in their network.
For all those of you wondering why the mobile operator was so sluggish in playing catch up with mobile user’s requirement, it’s mainly because of the city’s strict regulations due to which it takes years to approve a new cell tower in such sizable cities.
The mobile operator has been reported to have spent more than $2.4 billion on improving their network service in San Francisco over the past two years and this time, AT&T has used an upgraded distributed antenna system (DAS) in the new cell sites.
While the LTE speeds in other U.S cities are reportedly better on the same network, the current set up will certainly prove to be much beneficial for AT&T’s 3G users in San Francisco.

AM radio was the only audio source in a car for years. Then came FM and tape formats such as 8-track and cassette. A CD player is now standard in most vehicles, and many factory head units can also receive satellite radio from the subscription services Sirius or XM. HD Radio has recently given AM and FM better sound and extra features, such as additional channels and information.In addition to controlling the system's volume, head units usually include basic tone controls such as bass and treble to tailor the sound to the listener's taste. Many audio systems also include signal processing that automatically adjusts the volume, depending on the ambient noise in a moving vehicle. Some high-end OEM audio systems also have a separate subwoofer and subwoofer-level controls.
A car stereo system has to have an amplifier to increase the power of an audio signal so it's strong enough to move the speakers and create sound. Amplification is a two-stage process handled by a (preamp( and a (power amplifier).
Many head units have a small, built-in low-power amplifier that can "drive" smaller speakers. This allows the audio system to be reduced to just a head unit and a few speakers
B.(THE POWER AMPLIFIER).
For better sound requires more power. So higher-end systems have separate power amplifiers that are mounted away from the head unit due to their size and the heat they generate.its usually comes with luxury car like MERCEDES,AUDI,BMW ETC.
Speakers take an amplified electrical signal from headunit and convert it into mechanical energy that moves the speaker cone back and forth to create sound. Sound is essentially vibrations in the air that we hear, and a speaker cone creates these vibrations. The human ear hears these vibrations in a frequency range from about 20 hertz (very low bass(woofer or subwoofer) to 20,000 Hz (very high notes(tweeter). for better soundways woofer or subwoofer required. in modern car OEM system,these speakers are consist of 1 ohm and 2 ohm. an aftermarker speakers they all are 4ohm.
4.OHM in speakers
The ohm (symbol: Ω)in speakers or woofer behind the magnet,The ohm is the unit of measure for impedance, which is the property of a speaker that restricts the flow of electrical current through it. Typical speakers have impedance ratings of 1ohm, 2ohm, 4ohms,8 ohms or 16 ohms
a woofer is a speaker that focuses on the low-end of the sound spectrum. These speakers cover a frequency range from 20 to 5,000 Hz.its usually run by a external amplification,due to heavy output and input signals.in modern car its equipped with OEM woofer usually in parcel shelf behind back seat.
subwoofer, is a loudspeaker unit designed to produce extremely low-frequency bass sounds. Subwoofers cover a small frequency range between 20 and 200 Hz. They usually contain in a large speaker enclosure.
Woofers and subwoofers are commonly housed in sealed enclosures. The speaker enclosure plays an important role in the proper functioning of low-frequency speakers, as its purpose is to increase the clarity of the sound and reduce distortion.below are the types of enclosures.
A.(Infinite Baffle (Freeair)
The infinite baffle system is very simple and very easy to install. A baffle board is a wall the speaker is mounted to that separates the front and rear sound waves. The most important thing is to make sure the baffle board completely seals the front and rear areas. If the areas are not completely sealed, cancellation will occur and bass performance will be reduced drastically.
The most basic and simple of all speaker enclosures is the sealed box or acoustic suspension design.The acoustic suspension design has several advantages; it is easy to build, easy to tune and offers high power handling, tight response and extended low end output. Acoustic suspension enclosures produce lower bass because they roll off at 12 dB per/octave. Cone motion is better controlled at all frequencies because of the constant pressure on the back side of the cone, which enables you to run more power to the woofer
A vented enclosure is not much more complex than a sealed box. It consists, basically, of a box with a hole in it. However, despite its simple design, vented boxes are considerably harder to get good performance from than sealed boxes - although many times the extra effort can be worth it.The vent in the enclosure interacts with the volume of air in the cabinet and the driver to help increase output and reduce cone excursion at and around the tuning frequency. In fact, at box tuning, almost all the bass is produced by the vent - not the woofer.
For all of you those have not much enough knowledge about audio system,when replacing the speakers.please approach to the relative person regarding the issue.when ever anybody trying to replace stock system, go through all the system. OEM equipped system is little hard to replace with an aftermarket things due to their high impedance Ω in speakers. if you just replace the required speakers without knowing the stock speakers impedance Ω. chance are you will going to burn your headunit or amplifier or less output from new speakers. good luck and have a pleasant day. if need help please always feel free to contact me.

It’s time to rethink enterprise networks. They are overly privileged, slow, put the user last, and rest on flawed assumptions that slow businesses down while helping hackers tear across companies big and small. It’s time for a new foundation, a network that challenges the status quo and flips the script.
That’s why we founded Bowtie. Today, we're happy to introduce our company and invite you to try a new way to network.
Yesterday’s Networks are Failing Us
Enterprises today sit atop computer networks built where the businesses physically are, but enterprises themselves are dynamic collections of distributed people working toward a shared mission. More than ever before, these people are working independently, far away from the head or regional office, and each of them have unique access needs.
To maintain operations away from the places where enterprise networks are built, we have turned to remote access solutions, usually virtual private network software written in and inspired by the dial-up modem era. These solutions typically grant full access to enterprise resources, assuming that access control happens somewhere else. To simulate being in the enterprise network, users must first open and configure an application and then turn it “on” to connect. The employee’s reward for navigating the VPN is an overly privileged, slow, and brittle experience.
Compounding this situation, security incidents – ranging from sophisticated phishing campaigns targeting individual employees by name to Log4Shell-style remote code execution – are on the rise. Outsourced trust and legacy networks that make assumptions about who is connecting to them and what they should have access to can lead to debilitating, headline-grabbing attacks.
This happened to Uber in September 2022 when its VPN was hacked, handing control of much of its IT infrastructure over to the attackers. More recently, LastPass had its backup files stolen, exposing customer data to phishing and brute force attacks, and both Okta and Slack have had portions of their source code stolen from GitHub. These incidents demonstrate the pitfalls of overly privileged network design and of giving third parties exclusive control over your critical services.
The holy grail in security is to make the right thing to do the easy thing to do, but the legacy solutions most businesses use today are anything but easy and have users running for the exits, looking for any alternative to lessen the pain of the corporate VPN.
A Modern Approach for Enterprise Networks
The technology industry is marked with reversals to prevailing designs which, while initially counterintuitive, ultimately address problems in new ways. With enterprise networking, traditional design has been to build and concentrate privileged connectivity at every enterprise site, such as data centers, offices, or factories. Employees connect either in person or through a VPN, using “concentrators” to bring remote connections into principal sites from which user traffic is distributed. This pattern is known as the hub-and-spoke model, and is a natural offshoot of the need for enterprises to build underlying physical infrastructure at each of their locations.
There is a better way: rather than build privileged networks at each enterprise site and then bring users to those sites, the enterprise network moves out to the edge and exists inside each device used by the enterprise. These devices connect to each enterprise site concurrently and take the shortest path to reach those sites.
This model is founded on Zero Trust network access principles with each connection strongly authenticated, using enterprise identity, and limiting access to only what each employee needs for their work.
To be successful, users must only interact with this encrypted edge overlay network once, just as they would if they were connecting to wifi or their email in the morning. It must be invisible. The user needs only to log in to their computer, open a browser, shell, or other application, and begin their work.
By reversing the traditional network architecture – building unprivileged physical networks to power identity-driven virtual networks – and focusing the enterprise network on the edge, employees get the in-office privileged network experience they expect from anywhere they are.
Bowtie is a distributed enterprise edge networking product rooted in zero trust network access principles.
We improve upon agentless web gateway, proxy, or port forwarding solutions by giving customers a full network experience, encompassing every protocol and use case, unbounded by physical location. By moving the enterprise network to the endpoint, businesses can build their access policies and implement security monitoring and protection strategies just once rather than for each site and tech stack. Bowtie gives businesses a unified global view of their operations, regardless of locality.
To achieve this, Bowtie is built on modern encryption and tunneling technologies, supporting concurrent connectivity to multiple enterprise points of presence. Customers never again need to switch from network A to B to get access to that critical database or to improve performance. Bowtie connects to both A and B at the same time, without conflict, using high-performance tunnels to operate as close to wire speed as possible.
Bowtie’s greatest strength, however, is its invisible design. Users are often unaware that Bowtie is even operating, which is the same experience employees have always enjoyed sitting at their desks in the office.
Bowtie achieves this by investing in techniques to ensure connectivity is established even across adverse network conditions, using single packet round trip connection establishment so that the enterprise network is ready as soon as the wifi link comes up, and stays connected as users roam between networks. Improving security and user experience simultaneously is rare, and that is precisely Bowtie’s mission.
We set out to build Bowtie based on our experience as operators of security-sensitive enterprise networks where traditional assumptions no longer served us. In doing so, we set down a series of promises and principles that would underpin our product.
The first is embedded into the company’s name: Bowtie Works. To achieve our vision of moving the enterprise network to the edge, the highest objective we have is that Bowtie works. In the traditional in-person privileged network model, operators and users alike depend on the network being present and giving them access to the information and resources they need. A reliable network is a prerequisite.
Bowtie provides this seamless experience in software, from anywhere the internet is accessible, and we focus all of our efforts on ensuring that the connection always works. Reliability is the core requirement upon which all of our access control, visibility, and security features are built. Bowtie Works.
The other key principle underpinning the Bowtie product is that trust and security are paramount.
Being forced to choose between best-of-breed software and having agency over your security and data is a false dichotomy.
Enterprises should be able to leverage the ease of use offered by cloud-managed software models while retaining ownership and control of their deployments and software architectures.
To achieve this, Bowtie embraces the local-first philosophy of software engineering, giving customers complete control over their deployments, with no operational dependencies on Bowtie the company for the functionality of their networks. This is particularly true concerning the security critical elements of our solution. Unlike some network access providers, Bowtie cannot introduce new clients into a customer network, and our solution does not require routing all customer traffic through our data centers. Access control, encryption, and availability are under exclusive customer control, where they belong.


On May 12th, 1999
A signal of unknown origin was detected by a small group of people in a remote location of Southern California. Contained within the signal was a message with partial blueprints of an unknown device. Study of the incomplete blueprints led researchers to the conclusion that without additional data, no determination of its purpose could be made. Over the next 18 years, numerous reports of the signal were received from all corners of the globe, gradually growing in frequency until exposure to the signal had become a daily occurrence. These reports often contained obscure blueprints that were entirely unique. Over the years, it became apparent that these blueprints were actually part of a larger diagram detailing the specifications of a single device.


Mobile coverage is a key issue for consumers, particularly those in regional, rural and remote Australia. Achieving improvements in mobile coverage is a priority focus of ACCAN’s work. The Federal Government’s Mobile Black Spot Programme will deliver improvements to mobile coverage, but the demand for these improvements will far outstrip supply.
In December, 2014, ACCAN launched the Community Consultation Guide which is designed to help communities address issues with mobile coverage in their areas. The Guide sets out steps to help communities understand what mobile network operators look for when weighing up where to invest and it gives information on who they can contact and potentially partner with to achieve results.

SweGaN was awarded a significant grant from the European Commission to execute its “CoolHEMT” project targeted to develop and commercialize SweGaN’s revolutionary gallium nitride (GaN) on silicon carbide (SiC) structures into high frequency devices. SweGaN’s disruptive QuanFINETMstructure substantially improves the performance of high frequency devices used in the communication network and enables high frequency phased array communication modules.
SweGaN has been awarded a European Commission grant in the ultra-competitive Horizon 2020 SME instrument programme, where 1280 companies applied to the second round of the European Innovation Council (EIC) pilot. Only 130 companies were invited to pitch their innovation projects in front of a panel of experts who selected just 65 companies for funding.
The funding will be used to strengthen SweGaN’s team and to develop prototype devices taking full advantage of SweGaN’s proprietary GaN-on-SiC growth technology. The QuanFINETMstructure is the latest innovation coming from SweGaN which builds on SweGaN’s high precision interface control during the initial stages of growth.
“We are extremely happy to receive this grant especially in such stiff competition. The grant will help us to accelerate the development and commercialization of the QuanFINETMstructure into finished devices that can be tested by our partners developing the next generation communication systems for the 5G network,” says Olof Kordina, CEO of SweGaN AB.
High electron mobility transistor (HEMT) devices made on the QuanFINETMstructure has already demonstrated a higher power density, lower dispersion, and substantially better thermal management compared to devices made on commercial state-of-the-art GaN-on-SiC material. These advantages are instrumental for the next-generation communication network and for satellite communication.
“In addition to RF applications, we also see a great potential of our QuanFINETMstructure for power devices, based on its extraordinarily high breakdown voltage.” says Jr-Tai Chen, CTO of SweGaN AB.
The winning proposal was developed by Zaz Ventures, a specialized consultancy focusing on Horizon 2020 grant proposal writing. Xavier Aubry, managing partner of Zaz Ventures, commented: “Base stations are by far the largest power consumer within mobile networks, accounting for 80% of the total network energy consumption. SweGaN’s technology for GaN-on-SiC power amplifiers can reduce cost and improve energy efficiency to support the explosive growth of mobile data while limiting its carbon footprint”.

Background[ edit ] The basic protocol for sending data over the Internet network and many other computer networks is the Internet Protocol IP. The protocol specifies that each IP packet must have a header which contains among other things the IP address of the sender of the packet. The source IP address is normally the address that the packet was sent from, but the sender's address in the header can be altered, so that to the recipient it appears that the packet came from another source. The protocol requires the receiving computer to send back a response to the source IP address, so that spoofing is mainly used when the sender can anticipate the network response or does not care about the response.
IP spoofing and ARP spoofing in particular may be used to leverage man-in-the-middle attacks against hosts on a computer network.
Referer spoofing Some websites, especially pornographic paysitesallow access to their materials only from certain approved login- pages. This is enforced by checking the referrer header of the HTTP request.
This referrer header however can be changed known as " referrer spoofing " or "Ref-tar spoofing"allowing users to gain unauthorized access to the materials. Poisoning of file-sharing networks[ edit ] " Spoofing " can also refer to copyright holders placing distorted or unlistenable versions of works on file-sharing networks.
Caller ID spoofing[ edit ] Main article: Gateways between networks that allow such spoofing and other public networks then forward that false information. Since spoofed calls can originate from other countries, the laws in the receiver's country may not apply to the caller.
This limits laws' effectiveness against the use of spoofed caller ID information to further a scam.
This technique is commonly used by spammers to hide the origin of their e-mails and leads to problems such as misdirected bounces i. E-mail address spoofing is done in quite the same way as writing a forged return address using snail mail. As long as the letter fits the protocol, i. It can be done using a mail server with telnet.
Types of IP Spoofing: In many cases, IP spoofing is carried out for a malicious action; sometime IP spoofing is useful in website testing, live system checking. There are some sorts of attacks, which use IP spoofing to make attack successful like blind spoofing, DOS attack, non-blind spoofing, and MITM (Man in the Middle Attack) attack. Internet Crime Schemes. Current and ongoing Internet trends and schemes identified by the Internet Crime Complaint Center along with its description. Spoofing testbed at the University of Texas Radionavigation Laboratory, an advanced and powerful suite for anti-spoofing research. On the right are several of the civil GPS receivers tested and the radio-frequency test enclosure, and on the left are the phasor measurement unit and the civil GPS spoofer.
These spoofed signals may be modified in such a way as to cause the receiver to estimate its position to be somewhere other than where it actually is, or to be located where it is but at a different time, as determined by the attacker.
One common form of a GPS spoofing attack, commonly termed a carry-off attack, begins by broadcasting signals synchronized with the genuine signals observed by the target receiver. The power of the counterfeit signals is then gradually increased and drawn away from the genuine signals.
It has been suggested that the capture of a Lockheed RQ drone aircraft in northeastern Iran in December, was the result of such an attack. The students were aboard the yacht, allowing their spoofing equipment to gradually overpower the signal strengths of the actual GPS constellation satellites, altering the course of the yacht.
This has made GPS spoofing much more accessible, meaning it can be performed at limited expense and with a modicum of technical knowledge. Some of the most important and most recommended to use are: Install antennas where they are not visible from publicly accessible locations or obscure their exact locations by introducing impediments to hide the antennas.
Sensors can detect characteristics of interference, jammingand spoofing signals, provide local indication of an attack or anomalous condition, communicate alerts to a remote monitoring site, and collect and report data to be analyzed for forensic purposes . Extend data spoofing whitelists to sensors.
Existing data spoofing whitelists have been and are being implemented in government reference software, and should also be implemented in sensors. Use more GPS signal types. Modernized civil GPS signals are more robust than the L1 signal and should be leveraged for increased resistance to interference, jamming, and spoofing.
Reduce latency in recognition and reporting of interference, jamming, and spoofing. If a receiver is misled by an attack before the attack is recognized and reported, then backup devices may be corrupted by the receiver before hand over.
These installation and operation strategies and development opportunities described herein can significantly enhance the ability of GNSS receivers and associated equipment to defend against a range of interference, jamming, and spoofing attacks.Some common types of spoofing attacks include ARP spoofing, DNS spoofing and IP address spoofing.
These types of spoofing attacks are typically used to attack networks, spread malware and to access confidential information and data. LANs (Local Area Networks) that use the Address Resolution Protocol (ARP) are susceptible to ARP spoofing attacks. The ARP is used for the resolution of IP addresses on a network to MAC (Media Access Control) addresses.

Let me begin by saying that I firmly believe that there is no reason why digital audio can’t sound just as good or better than analog audio. While I certainly enjoy the smooth engaging sound of vinyl and also tape, I really appreciate the added benefits of having a library of digital files. However, I have too often experienced digital that sounds just a bit too, well, digital. You know what I mean.
For two years I have been striving to assemble the best music server, and the best DAC (within reason). But when I chose to thoroughly investigate the USB connection between those devices, I realized that the design of the USB link was paramount to achieving that analog flavor that I was after. So, I starting exploring the USB specification documents, and researching the science behind engineering a better USB cable.
During the development of this cable, I made comparisons to numerous other USB cables from different manufacturers and of different designs. Our USB cables are characterized by a very low noise floor, which gives the cable a very smooth and relaxed sound, while maintaining great detail and a controlled bass response. Other cables could be edgy or digital sounding, or lacking in bass, or emphasizing bass frequencies which tended to cause bloom.
Our cables are highly refined, clean and open sounding with a solid bass and good micro-detailing. The music sounds involving and engaging. It is not fatiguing, which is evident when music contains difficult to render instruments like flute, harmonica or violins. An open soundstage is evident with clear imaging and plenty of air and sustain.
For a little background on myself; I am a software engineer, and I’m an avid electronics hobbyist. I Build my own music servers, and have built my own DAC with various tweaks. I’ve also built tube amplifiers and linear power supplies. So it’s with this electronics background and an understanding of the digital realm that I pursued my experimentations with building a better USB cable.
As computer audiophiles, we’ve all heard the adage that bits are bits, so how could a wire that carries digital make any difference. When you hear the difference between USB cables, you soon realize that the digital cable has a significant involvement with the enjoyment of the music. Being curious, I asked how USB cable architecture can make so much difference. When it’s done right, a good USB cable can improve one’s enjoyment of the music.
Digital noise and jitter is prevalent in all digital signals to a lesser or greater extent. It's a critical issue in USB cable communication, because the USB signal travels in real-time between a Music Server and DAC. Moreover, when errors in the music data occur, there is no provision in the USB specification for the DAC to request a re-send. Therefore, the integrity of the digital music must be accurately preserved within the USB cable traffic.
In designing this USB cable, I have carefully chosen the wire metallurgy, gauge, cable architecture and dielectric. I've paid special attention to reducing both digital noise and jitter timing issues in the cable. I carefully chose the wire shielding or the lack thereof. All wires that carry a voltage emit electromagnetic radiation as a field surrounding the wire. To combat this EMI effect, which impacts the wires in proximity to it, I chose to use wire shielding on the 5 Volt (Vbus) lead. However, I chose not to shield the data plus and data negative wires, because I want their EMI to dissipate away. Jitter noise is introduced by the timing of the USB packet transfers across the wire, and the nature of the positive and negative data lines which are utilized by the USB software to subtract noise that may accumulate on the wires. We provide our USB cables in basically two versions. The "Standard" cable has the 5 volt shielded wire for those DACs or USB converters that require voltage to communicate and/or operate. We also offer the "Data Only" cable for those DACS that do not need the 5 volt wire. We recommend using the data only design if your DAC can accommodate it.
The source of noise in computer audio is the most important issue to deal with for discriminating audiophiles. It’s critical to realize that the modern consumer laptop or desktop computer is extremely noisy by nature. They work just fine for everyday use, even though they have noisy power supplies, inaccurate clocks, poor USB timing and inconsistent, shared power delivery. By disconnecting your computer or laptop power from your DAC or USB converter, and supplying clean power externally, you’ll seriously improve your digital sound.
The USB specification clearly defines the design parameters for the cable and transmission protocol. We followed the specs as closely as possible, only diverging when it made sense from an audio standpoint opposed to a computer data position. The two data lines work in a duplex fashion which allows for summing the data to eliminate noise built up during data transmission. The host USB device expects the music data packets to arrive at specifically timed intervals, in the microsecond range, and without phase shifting between the + or – data lines. The cable is supposed to be approximately 90 ohms impedance, give or take 15%. The binary data within the packet stream needs to be within specific voltage tolerances upon arrival to be correctly termed a one or a zero. There is no provision for resending the data if there is a bad read. Timing by the computer clock, the USB clock and the DAC clock are all working together to assure a properly timed stream of bits. This is extremely critical for the music to be rendered accurately. We have paid careful attention to these requirements, as well as other concerns, in the design of our USB cables.


One of the most popular and intelligent fire detection systems is an addressable system. Named, as each device, whether alarm or call point on the system has a unique ‘address’ and can be located directly. All the devices are connected to a main panel but by having these ‘addresses’ it can be easier to pinpoint the exact location of smoke, fire or false alarm.
Covering large spaces
Locations such as care homes, hotels, hospitals, warehouses, and large commercial spaces are ideal for addressable fire alarm systems as they can cover a wide range and allow extra time in the event of a fire or if it is false, minimise disruption. This type of system can also be used intelligently; programmed in a way to limit interior services such as lifts or ovens when an alarm is raised, again aiding people to avoid hazards.
Clever maintenance and servicing
As each device on the addressable system has a code or ‘address’ making locating it much easier, therefore if it has a fault our engineers can communicate with it quickly. Additional devices can also be added to the network, allowing an almost limitless size. With each device also having a wired loop feature, addressable alarm systems are cost-effective to scale up and have the flexibility to be programmed depending on their location or adjusted if requirements change.
Safe and reliable
Being able to pinpoint exact locations of smoke, fire or a false alarm gives those using the system valuable time and peace of mind. Quicker and more efficient repairs, upgrades and diagnoses allow consistent protection without hassle or disruption. All this makes an addressable fire alarm system a great choice.

As humanity ventures further into the cosmos, the need for efficient and high-quality communication grows more critical. NASA’s upcoming Artemis II mission marks a significant milestone in this journey, introducing cutting-edge laser communication technology that promises to transform our approach to space communication.
Scheduled for launch in 2023, Artemis II is set to be the first crewed mission to utilize laser communication technology. This mission will employ NASA’s Laser Communications Relay Demonstration (LCRD) to transmit data from lunar orbit back to Earth, showcasing the capabilities and potential of this transformative technology.
Traditional radio frequency (RF) communication has been the bedrock of space communication till now. However, as we aspire to explore deeper into the solar system, the inherent limitations of RF communication, including slower data transmission rates and the requirement for larger antennas, become more evident. Laser communication emerges as a game-changer in this scenario, offering data transmission up to 100 times faster than RF and necessitating smaller, lighter equipment.
The LCRD is a critical component of the Artemis II mission, marking the first time laser communication is tested aboard a crewed spacecraft. This endeavor aims to establish a reliable, high-speed communication link between the Earth and the spacecraft, representing a significant stride in human space exploration.
The advent of laser communication technology brings several advantages beyond speedier data transmission. It also facilitates higher resolution imagery and real-time video communication, significantly enhancing the quality of scientific data collection and boosting astronaut morale through improved communication with Earth.
Nonetheless, implementing laser communication in space comes with its unique set of challenges. Maintaining a stable connection between the spacecraft and Earth requires precise pointing and tracking due to the narrow focus of the laser beam. Atmospheric conditions, such as cloud cover, can also disrupt the laser communication link.
In response to these challenges, NASA has developed an innovative Adaptive Optics system for the LCRD. This system compensates for atmospheric distortion, ensuring a steady, high-quality connection even in adverse conditions.
The Artemis II mission’s successful demonstration of laser communication will pave the way for its integration into future deep space exploration missions, including the planned crewed missions to Mars.
In conclusion, the Artemis II mission signifies a pivotal moment in the history of space exploration. By harnessing the power of laser communication technology, NASA is not only revolutionizing how we communicate with spacecraft but also opening new avenues for scientific discovery and human exploration of the cosmos.

Anyway, Pachube used to be a paid service, but they recently (this month) made the service completely free for all users. An Overview of the Pachube API Documentation gives you a sense of how things work. There is also an API Quickstart that is useful if you know curl or hurl, command-line communication for scraping and posting data.


The Public Utilities Commission of Ohio will add another area code in some western and southern parts of the state.
The 326 code will officially take effect in March 2020 and be overlaid on top of the existing 937 area code that serves cities such as Dayton and Marysville.
The commission says all existing 937 area code users will keep their current numbers and area code. The 326 area code will be assigned to new numbers in the 937 area code.
Telecommunications officials say the 937 area code is expected to run out of available phone numbers in 2020.

Some people describe the internet as " a neverending worldwide conversation". Of all mass media, the Internet was used by people the soonest. Radio existed 38 years before 50 milion people used it, TV 13 years, computers 16 years, the Internet - just four years!
How did it start? In 1969,during the Cold War,American experts who developed top secret systems and weapons started work on the ARPAnet, grandfather to the Internet. At that time there were only a few large, powerful research computers so not many experts could use them. It protected the flow of military information. It created a network between computers that were far from each other. They could exchange information. The first connections were not very successful. At first, four computers were connected. Later there were problems because different models of computers were connected but they could not work together. The whole system was perfected in the next years and we know that computers are still developing. ARPAnet brought several new things: email (electonic mail) with which we can send messages to other people on the net. With telnet we can control the computer even if we are in a different place.
As more and more people used the net, it was no longer safe for the army so in 1983, MILnet, a military only network, was started. Then Local Area Networks (LAN´s) were started. Many universities and scientists used them. In 1986, one LAN formed a new network, called NFSnet. It first connected the five American supercomputer centres, then all major universities and it slowly replaced the slower ARPAnet which was finally shut down in 1990. NFSnet formed the basis of today´s internet

In 2019, Surtronic has delivered 331 Real Time Passenger Information (RTPI) displays to FARA, a leading public transport company based in Trondheim, Norway. FARA chose Surtronic for its excellent track record, product expertise and proven quality.
The displays are installed in the city of Trondheim as part of a larger project FARA has won with AtB. AtB is a mobility company responsible for the provision of public transport in Trøndelag.
Surtronic has designed, developed and delivered 266 TFT and 65 double sided 4-line LED RTPI displays. All displays were mounted inside new bus shelters. The entire project is delivered within agreed delivery schedule.
In Q2 2019, Surtronic will install 12 R-net Real Time Passenger Information (RTPI) displays in Hoofddorp, a city close to Schiphol Airport located in the Haarlemmermeer municipality in the Netherlands. The maintenance and management of the displays will be carried out by Surtronic for the next 10 years.
The R-net RTPI displays will be placed at bus stops along the R-net bus routes. On these high-quality displays, the real-time departure times of the buses are shown to commuters. Surtronic not only provides the actual displays, but in cooperation with parent company ARS Traffic & Transport Technology they also provide the complete system including the server and maintenance for 10 years. With the use of the RTPI displays, Surtronic guarantees that the bus stops are provided with dynamic, up-to-date travel information for the passengers.
The Hague Bus Station
In April 2018, Surtronic installed 8 49" TFT screens with a brightness of 2500 Nit and 10 full colour 10mm Pixel Pitch displays for our customer Regio Haaglanden via Strukton Systems.
Regio Haaglanden built a new bus station in The Hague with centralised indoor passenger information for all passengers and 10 special lanes for the positioning of busses. Our full colour displays are used to indicate bus lines and departure times for passengers.
Utrecht Bus Station
In November 2016, Surtronic provided 23 double sided 24", six 65" and three 55" Transflective and Bonded TFT screens for the City of Utrecht via Strukton Systems.
The customer had some special requirements for this project, namely a combination of Transflective and Bonded TFT screens for units larger than 32", which have never been requested before. Result of this special requirement and the skilled implementation by Sutronic is a high quality product readable in all weather conditions.
The response of the customer and passengers on the bus station in Utrecht is very positive.

Server Network Hardware
What networking hardware devices does a dedicated server come provided with? How could they affect the actual functioning of your Internet sites?
In the event that you host your websites on a dedicated server, you would expect that they will perform ultra fast and that the access speed to them will depend only on the Internet connection of the site visitors. Having said that, this is not going to be the case in case the hosting machine has lousy network connectivity or uses a network card, which just can't deal with high volume of website traffic. If this is the situation, it will take a while for your websites to load if many people open them at the same time or visitors might even see error messages. Consequently you may lose site visitors as almost certainly many people will never return to your site in the event that they have experienced issues or slow loading speeds. That's why you need to pay attention to the network components of any new hosting machine that you acquire and not only to the main hardware like Central processing unit, Random access memory or hard disk drive.

Phones on Planes
The EU is making a major change to its flights which will allow passengers to use 5G whilst travelling.
Phone calls and surfing the internet will be allowed on EU flights as of next summer, it has been announced.
Airlines that operate within the European Union will soon be able to offer 5G to their passengers, allowing them to make calls, stream music and chat over social media.
The frequencies for in-flight 5G (5 GHz) are different from those necessary for flying a plane (4.2 to 4.4 GHz), meaning there is essentially no risk of the pilot's transmissions being interrupted.
It's unclear at the moment whether UK airlines will adopt this service.

Traffic Signal Inspection
Traffic signal inspection is absolutely necessary for both new and updated signal systems. With all of the highly developed equipment and soaring technology, if often appears that signals are functioning accurately; however, detection and electronic communication between adjacent signals could be on the cusp of a serious malfunction if not properly installed and/or checked on a consistent basis.
QCM is trained with all proper certifications and knowledge to keep you and your signals up to date and functioning at their best. During the installation process, our team reads the drawings to verify that contractors are in fact installing the appropriate materials and that the quantities of wiring, conduit, splice connectors, water tights, etc are not only the correct items, but are also positioned in such a place that will allow for easy access to inspect and repair in the future of the signal. During installation along with maintenance of the system, QCM insures that the software/computer system not only operates properly but efficiently as well.
QCM pays attention to the smallest details that others often overlook; such as, when a camera is installed to detect traffic, QCM sets the camera to detect only the lane it is in control of. More times than not, these cameras detect automobiles in other lanes, and that will throw the entire system off kilter. QCM can handle all inspection of traffic signals, whether it be loops that chatter to each other, cameras that detect the traffic, or the old fashion system of loops.

The Pentagon is looking for a solution when it comes to their communication equipment and connections. They require security, reliability, and versatility around the world and under all manner of circumstances.
This is what makes the problem of satcom incompatibility especially pressing for U.S. defense. After an 18-month study, the Pentagon found that while there are opportunities for expanding into commercial communications satellites, many of its outdated terminals are unable to connect.
Modern satellites have a lot of offer the military in terms of capacity, ease of connectivity, and considerable cost savings. As the commercial satellite market grows, prices decrease and capacity and choice increase. Consistent satcom innovation makes the prospect of utilizing private satellites an attractive one for the Pentagon, but it’s not as simple as plugging in and connecting.
The study found current military terminals are the primary hurdle to commercial satellite integration. Highly customized and outdated compared to today’s technology, these terminals would require a major upgrade that could take decades and would require a huge investment. This would include requirements to update all manner of military communication equipment, which is no small feat considering how complex tactical radios and military headset specs can be in and of themselves.
Though it would be a massive undertaking, the Pentagon has many good reasons for pursuing such a course of action. If successful, the upgrade would allow for seamless connectivity and more nimble responsiveness in specific situations. There are still many concerns with how advanced commercial technology can be modified to meet with military requirements. Then there is the challenge of upgrading individual radios and other communication equipment.
There’s also the need for utmost security, stealth, and flexibility, which modern satcom technology can improve upon. This has become a primary concern as enemies are constantly seeking ways to obstruct or jam military satellite networks. As many service members can attest, this is a major venerability with outdated terminals.
For all the advantages presented in switching over to modern satcom technology, it’s not going to be a quick or easy change for the Pentagon. Preparation, testing, implementation, and full adaptation is going to take a lot of time, energy, and investment, but the need to upgrade and keep military technology current is imperative for national defense on an increasingly tenuous global stage.


We use it every day, but have you ever thought about the economics of the internet and its infrastructure.
Just thirty years ago, there was hardly any economic activity on the internet, which was used to send small data packages between individual users over dialup (The same network as your gran’s landline phone). Now the internet is a mega way of traffic with tens of millions of people streaming at any instant, and we are no longer tolerant of delays. The development of the infrastructure to support this has led to and is integral in the continued prospering of many emergent industries. These range from cryptocurrency, ride-sharing apps, streaming services, and online retailers. All this while also providing immense efficiency savings in administrative processes from general research and development to the provision of government services. There isn’t an industry the internet does not have a hand in today, and all told is thought to contribute US$2.1 trillion to the United States’ US$20.5 trillion yearly GDP, according to a 2019 study from the American Internet Association.
So how does the internet work:
To explain this, I will use a simple example of you accessing News.com from your laptop. On your laptop, you have access to an ISP (Internet Service Provider) which connects your device to the physical infrastructure that carries data. The ISP takes your request to the name server, in this case, News.com, and News.com responds by sending back the requested information to the ISP, which is transmitted to your laptop’s IP address and rendered into a form that you can use. The ISP connects to the name server in two ways.
The first option is the simplest. If the user and the server contract with the same internet service provider, then the data can be requested and delivered within the network of a single ISP.
The standard option is to reroute a user request from the name server to geographically distributed networks of servers near users like you called content delivery networks (CDN’s). Sometimes this is called “moving data to the edge of the network.” Because such networks are physically close to users by relocating the name address content, CDNs reduce the response while not requiring the name server and user to be within the same ISP network.
Both methods require massive infrastructure with significant overhead and maintenance costs. CDN’s often are comprised of office building-sized servers, and an extensive network of underground fibre or telephone wire is required to connect between networks traversing across countries and the oceans.
Several market transactions allow this to happen:
Several market transactions allow this to happen:
- Users typically pay ISPs monthly to connect customers using infrastructure ranging from ADSL and Fibre optic cable to satellite or other wireless options. This includes companies like Telstra and Optus.
- The owners of domain names (In this example News.com) pay server firms to provide them with a name server which stores their content and allows users to access it. These include companies such as Cloudflare and AWS.
- There are transactions between ISPs who share networks to increase coverage and decrease congestion.
Given the importance of internet infrastructure, is it safe in the hands of the private sector?
Naturally, carriers have incentives to build more lines, improve existing infrastructure to make more connections, and relieve congestion, which helps the firm gain revenue and reduce costs (By increasing their customer capacity and service desirability). These incentives are consistent with the desirable long-term objective of more efficient internet access and better options for routes to send and receive data in line with demand. This analysis has held over time, as shown in the below graphic, which graphs the inflation of internet services each year from 1997 to 2021, tracking a net decrease in prices of 20% (not corrected for inflation), while users now have access to connection speed multiple times faster today.
Beyond this, an interesting question regarding whether the internet is ‘safe’ in the hands of the private sector is the balance between private incentives to infrastructure improvement compared to gains in the network (i.e., the internet apparatus as a whole). For example, transit lines, improvements to them confer benefits to all the other complementary components. Do most of the gains from better transit lines go to the content providers who use them, the users who enjoy faster content, or the internet service providers who may gain revenue from users for better services?
The consensus is that improvements benefit more participants than just the firm providing this access. While access providers potentially gain more revenue, users gain better service, and application providers get the opportunity of new frontier tech for their data-intensive services such as streaming and more immersive products as we track further into the world of virtual reality. The gains from improvement are widespread, while the private costs and commercial risks are concentrated in the one investor group. I worry that the comparatively small private incentive to upgrade quality may eventuate in a large gap between service capability and society’s broader long-term interest, as the providers do not necessarily stand to benefit financially from large improvements as potential gains would be severely undermined by a spiked cost to cover development combined with a high degree of substitutability between internet providers. As such private based infrastructure possibly inhibits the development of internet services which would dramatically increase the economy’s productivity. This discrepancy in incentives and how to overcome it remains an open research area at the forefront of public policy. Finally, rural access is regarded as the key concern in the private provision of internet services. It is such an economic challenge that rural communities in the decidedly first world and affluent nations such as Australia and the US have less internet access than low-income families from a dense city in a developing country. For example, ten per cent of the rural US population still does not use the internet today. This is largely driven by a lack of access due to pricing or availability evident in a 2019 A Pew Research survey conducted in February 2019 which found that 46 percent of the US rural population does not have broadband access.
This shortfall in supply arises because the viability of internet service to given geographic areas relies on the efficiencies of economies of scale. Thus, operating cell towers, data centres, and content delivery networks (CDNs) exist endogenously in densely located areas. Further laying lines between locations involves high fixed and marginal costs, so low density may not have sufficient demand to induce such investments.
Further demand for better quality enterprise level services from densely located areas due to often professional service heavy local economies further incentivises this disparity. This is because providers prefer more locations where more buyers are willing to pay for the expensive frontier quality. This has a perverse effect as access to these services often contributes positively to an area’s productivity and general wealth, providing an excellent example of Marshallian agglomeration.
Many things have been tried to alleviate this. For example, the US passed the 1996 Telecom Act which established the e-rate program, which taxed telephone calls to finance subsidies for rural broadband, while Australia has its recent Nbn Program, which will when complete provide fibre coverage to most of Australia bar a few regional areas which will use satellite and fixed wireless technologies.

Marine stereos are designed to be used on Boats so they run off of 12 volt battery power. But what if you want to use a marine stereo in your hot tub, on your patio or by your pool and you need to be able to plug it into a wall socket? You will need a 12 volt power supply like this one that can adapt the power from your home to the type of power that your stereo can use. Not just any 12 volt adapter will do. These little power supplies that you commonly see, I call them wall warts are not going to do the job because they don't provide enough amperage. Most of these are less than 1 amp and that is just not enough.

Because car stereos work off direct current, they can be effectively moved inside with only minimal hassle. Because car stereo systems work with direct current DC , they can be powered directly by a car battery. If you want to use a car battery for a temporary arrangement, the battery will serve as its own power source. Consult your car stereo installation manual to determine which wires are assigned to speakers; car stereo speaker wires are typically color-coded, though some manufacturers rely on the car's wiring harness to connect the correct leads to the proper speakers. Strip a small segment of insulation from the end of a length of speaker wire, wrap the exposed speaker wire around the exposed speaker lead and use electrical tape to secure the connection. Repeat this process for each speaker, keeping in mind that car stereo systems may be designed to power up to 12 or more speakers.
5 Best Radio Antenna for Your Car in 2018
How to hook up a subwoofer to a stereo system Hint: You don't necessarily need a receiver with subwoofer output jacks. Subs can provide a foundation to the sound that few speakers can muster on their own. So adding a sub is not just about adding more and deeper bass; rather, a properly integrated subwoofer can improve the overall sound of the system.
