What is a choke?
An inductor put in series (in line) with a conductor, such as a cable or motherboard trace, obstructs or restrains adjustments in existing as well as works as a low pass filter. Because inductors restrict or choke changes in existing, they are additionally called "chokes". For instance, a broadband (wideband) predisposition choke according to the DC bias of an amplifier blocks a wide variety of high frequencies while allowing pass-through of the dc current. This way, a predisposition choke isolates the DC predisposition from the RF signal to the amplifier.
The Federal Communications Commission (FCC) has actually produced standards and also accredits electronic tools offered or manufactured in the USA for satisfying electromagnetic disturbance (EMI) requirements. Worldwide electro-magnetic compatibility (EMC) requirements organizations consist of CISPR, IEC, ISO, and EN. FCC laws are compulsory and relate to devices such as computer system, switched-mode power materials, television receivers, transmitters, and also industrial, clinical, and clinical (ISM) devices that emit RF radiation. Inductors are utilized in electric circuits to decrease EMI by undermining high-frequency noise in order to fulfill EMC emission as well as immunity demands.
Present Rise Time with 1 µH inductor throughout 10 Vdc.
and also 10 ohm Lots is less than 10 us.
Present Surge Time with 10 µH inductor across 10 Vdc.
as well as 10 ohm Tons is higher than 40 us.
Exactly how can I improve the filtering system efficiency in a circuit?
Generally, high inductance worths are needed to strain radio frequency noise, as well as the other way around: lower inductance values are utilized to remove greater frequency noise. High inductance worths properly slow down the present surge time of short-term events, such as closing a switch. The graphs in Number 1 show just how a 10 µH inductor "smooths" the rise time more than a 1 µH inductor.
Inductors can likewise be integrated with capacitors to develop a lot more effective LC filters. Several possible LC filter positionings exist, each including compromises in monotony of the depletion vs regularity habits as well as the intensity of the filter roll-off.
This Coilcraft referral layout record provides 3rd order Butterworth and 7th order Elliptic LC filter reference designs that use off-the-shelf inductors to achieve cutoff frequencies in the 0.3 MHz to 3000 MHz array.
Although making use of high inductance values or creating LC filters improves filtering, doing so requires even more board room. Due to the fact that reduced inductance worths can be utilized for filtering higher regularities, switching over to procedure at a higher frequency may allow the use of smaller sized inductors.
Just how are inductors utilized in power converters?
In changed mode power products, inductors are made use of to keep energy and move the energy to an ouput load or capacitor. Inductors in power converters offer to filter the "surge" present at the output. High inductance worths lead to lower surge present, which improves performance and also decreases EMI. See Figure 2.
Just how are inductors utilized in tuned circuits?
Tuned circuits are made use of for transferring or receiving radio or microwave regularity signals. Inductors can be integrated with capacitors to develop tuned LC circuits such as oscillators.
Reduced ripple existing DC-DC converter with 7.5 µH Inductor.
Low surge present DC-DC converter with 75 µH Inductor.
How does Q element impact the bandwidth of LC circuits?
Q factor (Q) is a step of the dissipative quality of an inductor. High Q inductors have reduced dissipation as well as are made use of to make finely-tuned, narrow-band circuits. Low Q inductors have greater dissipation that results in wideband efficiency.
What is the Self Resonant Regularity of an inductor?
Actual inductors have turn-to-turn winding capacitance that acts as if it were a parallel circuit component. The self-resonant frequency (SRF) of an inductor is the regularity at which the inductive reactance is equivalent in magnitude to the capacitive reactance of the windings. At the SRF, the inductive and also capacitive phase angles cancel and also the impedance is properly purely resisting. Insusceptibility magnitude boosts with regularity as much as the self-resonant regularity (SRF), where the insusceptibility of an inductor is at its maximum worth. At regularities above the SRF, resistance lowers with increasing frequency.
Resistance (Z) is a feature of electrical elements that includes a vector mix of resistance and also phase. Resistance has a dissipative high quality: power is made use of and also not recovered. Phase is the delay in between a used voltage throughout a component and the current streaming with it, frequently shared as an angle in levels ( °) or radians. Both the AC resistance and phase inductor of inductors vary with frequency.
Exactly how are inductors utilized for resistance matching?
Resistance matching normally entails matching the insusceptibility of a source of power to the insusceptibility of an electric lots. Maximum power is moved from the resource to the lots when the insusceptibility of the lots is matched to the insusceptibility of the resource, enhancing the effectiveness of the circuit. If the tons is capacitive compared to the source, inductors can be used to counter the capacitance of the load and also hence match the insusceptibility.


Uplift Capture is a cloud-connected mobile app that pairs and keeps two iOS devices in sync in order to capture time-synced video. All of this means there are a number of considerations when it comes to device connectivity. This article will explain the methods and the connection requirements Capture has in order to function correctly.
Internet Connectivity Requirements
Uplift Capture requires internet connectivity to open and to fully function. This is because Capture connects to our servers in the cloud to get the list of available movements, your full list of athletes and settings, and to upload the captured video at the end of the session. Thus, it’s always recommended that you run Uplift capture while connected to a strong wifi network. In addition, because both devices need to see each other to pair, both devices need to be connected to the same network (see all best practices here).
In theory, you could open the Capture app on both mobile devices, pair the devices, pick a movement and athlete, and enter camera setup while you’re connected to the internet and then bring the devices to an area with poor or no internet connectivity and still be able to record. However please note that this is an untested/unsupported scenario and we can’t guarantee it will work. For best results, a strong wifi connection is your best bet.
Device pairing and syncing
Aside from connecting to the Uplift cloud, Capture also requires that both mobile devices are paired with one another, and that they stay in constant sync so that the videos captured on each devices can be used to generate full 3d data. Below we’ll explain how Capture pairs and then syncs both devices.
Uplift Capture uses Apple’s Multipeer Connectivity technology for the primary device to find and pair to the secondary device. This is essentially the same technology used by services like Air Drop to discover and connect with nearby devices.
Because entering pairing mode requires that one device is “searching” and the other is “discoverable”, do not enter pairing mode on both devices at the same time. The device that initiates pairing will become the Primary device, and the one that gets paired with will be Secondary.
Pairing enables the two devices to send messages back and forth to one another. These include the primary telling the secondary to start or stop recording, that the recording mode has been changed, one device letting the other know it has low battery or is getting hot, and other important information.
One of the most important reasons for device pairing is to keep the devices in sync.
By default, Capture uses a peer-to-peer (P2P) approach to syncing the two devices.
This means that each device pings the other constantly (except in the midst of recording a clip) to communicate the local clock time on each device. This clock time is used to calculate an offset between the two devices at the time recording starts, so that when both videos are uploaded to the cloud, they’re perfectly time-synced during processing.
Why might device pairing drop?
While the devices should remain paired as long as they’re in range and in use, there are some cases when device pairing drops. This can happen for a number of reasons, including radio interference, the app or device being idle for long enough that iOS severs the connection, or some other process in iOS causing connection to drop. In these cases, as long as both devices are still in range with the wifi radio toggled on, you should be able to repair quickly and easily.

How Bad Actors Use ID Spoofing
Many wonder how bad actors are able to use so many different numbers? The bad actor opens the application (web or mobile) of the spoofing provider. They enter the number they wish to call, followed by the number they wish to display. When they press “send” or “call,” the call is sent through a VoIP service. The outbound caller ID is changed, and the call is connected to the desired destination phone number.
Best Practices | Preventing ID Spoofing requires ongoing maintenance to be successful
Don’t rely on caller ID to verify who’s calling. It can be nearly impossible to tell whether the caller ID information is real. Here are a few tips for handling these calls:

Helsinki, 15 February, 2006
Enermet and Elisa have developed in cooperation a mobile data solution suitable for automatic meter reading (AMR). The solution allows cost-efficient transfer of energy metering data over the GPRS (General Packet Radio Service) network throughout Finland.
Together with Enermet’s AMR system and integrated GPRS meters, Elisa’s mobile data services provide a flexible, cost-efficient meter reading solution for household sites as well as commercial and industrial sites. In addition to collecting metering data, the two-way AMR system enables various control options and gathers information related to, e.g., electricity quality and network monitoring.
“GPRS data transfer complements well Enermet’s selection of communication options. GPRS provides a secure on-line connection between the meter and the meter reading system: the metering site can always be reached without separately installing a connection,” says Antti Aumo, Enermet’s VP of Marketing, Product Management and Development.
“At Elisa, we want to help our customers to enhance their productivity through communication services tailored for the company's operative processes. Enermet’s meter reading service is an excellent example. We believe that together with Enermet, we can provide value for both energy companies and their customers,” says Anssi Okkonen, Elisa’s Selection Manager in the Business Customers Unit.
Enermet was the first supplier of AMR systems to adopt GPRS communication as a tool for reading household energy meter data in Denmark in late 2004 and in Sweden in 2005. Enermet has actively sought a partner to offer a similar solution also in Finland. The new solution tailored in cooperation with Elisa enables easy implementation of GPRS technology in energy companies’ automatic meter reading.
Mobile data services can be thought of as a wireless extension of the Internet, allowing fast and reliable data transfer. The data connection can be set up and protected using common TCP/IP based tools. The end result is a secure Virtual Private Network (VPN) dedicated to meter reading, in which disturbances and data security risks have been minimized.
“Our GPRS solution is already being implemented at, e.g., Savon Voima and Järvi-Suomen Energia. Energy companies can easily acquire the mobile data service either from Enermet or directly from the operator," says Aumo.

Leavenworth-area work will add Public Power Benefit access to broadband internet
Chelan PUD crews are at work in lower Chumstick Canyon, just outside Leavenworth, expanding the high-speed fiber network as part of the District’s Public Power Benefit program approved by PUD commissioners last year. In all, Chelan PUD is expanding access to the network for about 1,000 customers this year in parts of Cashmere, Manson and Leavenworth.
PUD crews started building new fiber distribution last week in lower Chumstick Canyon to reach about 55 homes by the end of June. They are working from Cascade High School north to Freund Canyon.
Now is the time for customers in the newly built-out area to contact a retail service provider and make a connection request to receive broadband internet, television and/or telephone over the PUD network. Chelan PUD’s broadband network can deliver internet speeds of up to 1 gigabit per second (GBps).
Drivers and bicyclists on Chumstick Highway can expect to see PUD and contractor crews in the area for the next 30 days, Monday – Friday, generally from 7 a.m. – 4 p.m. They will be placing equipment to prepare for the new fiber service.
For more information about the planned expansion, please visit the PUD website www.chelanpud.org and click on “My PUD Services.”
As chosen by customers during strategic planning, the Public Power Benefit will bring access to the PUD’s high-speed internet fiber network from about 69 percent to 85-90 percent of county residents within 11 years. Locations for future work are identified each year during budgeting for the following year.
District staff has identified the areas slated for additional connections in 2016 that are next to existing fiber in Manson, Cashmere and Leavenworth. Expansion criteria calls for building in areas where connections can be added at the least cost per premises passed. Broadband network expansion in the Manson area is scheduled to start in early July. Work in the Cashmere area along Tigner Road started in early May.


NOTHING NEW UNDER THE SUN (ALMOST)
11th December, 1901 : The feasibility of global communication by wireless was demonstrated beyond all possible doubt today, when a signal transmitted from Cornwall was detected in Newfoundland, over 2,000 miles away. The Italian wireless pioneer, Gugliemo Marconi, planned and carried out the experiment. At Poldhu on the Lizard he set up an aerial 164 feet high. At St John’s in Newfoundland a kite took an aerial even higher. At 6 p.m. GMT Poldhu started to transmit the three dots of the letter S in Morse code at five minutes intervals. Faint but clear signals were detected almost immediately on the other side of the Atlantic. Today’s triumph is the culmination of a series of experiments with wireless by Marconi. He started at home in Italy in 1895 attempting to transmit messages from his house to a receiver in the garden.


This version of the Evacuator Sitemaster alarm features a manual call point which activates the sounder. Unlike standard call points the Evacuator has a membrane instead of breakable glass which can be reset after activation. The alarm sounds at an extremely loud 110dB which is audible from great distances. For larger or noisier areas the Evacuator Sitemaster alarms can be easily linked using 2 core wire.

Difference between revisions of "VPN client"
m (1 revision)
Revision as of 16:12, 20 November 2012
The FH JOANNEUM intranet is being managed and protected against abuse by the central IT services. Internet access is being routed through a proxy as well. There are 3 options for gaining access to the intra- and internet:
- with a VPN tunnel (discussed in this article),
- with a dynamic ethernet port or
- via wireless LAN (WPA-TKIP Enterprise).
In order to establish a VPN tunnel connection, the client computer needs software that is compatible with the VPN concentrators. Cisco produces their own, proprietary software for connecting to VPN 3000 concentrators. At this time, there are the Cisco AnyConnect VPN Client and the (outdated) Cisco VPN Client.
Additionally, Mac OS X 10.6 ("Snow Leopard") can connect to the FH JOANNEUM VPN without any third-party software.
Mac OS X 10.6 built-in VPN connection
Philipp Rappold of IND09 wrote an instruction manual for creating a Cisco-compatible VPN connection with OS X Snow Leopard. Thanks a lot!
Important notice: The VPN server address has changed - use vpn.fh-joanneum.at instead of the IP address shown in the PDF.
Cisco AnyConnect VPN Client
The Cisco AnyConnect VPN Client is a modern alternative to the older Cisco VPN Client, which has been the source of many past problems under both Windows and OS X. The new client is smaller, faster, more stable and efficient, does not need access profiles and, in fact, no other configuration whatsoever. Download it here:
Please note that the Cisco AnyConnect VPN Client cannot be used when you are already connected to the FH JOANNEUM intranet (via "wpa4fh", "wireless4fh" or a dynamic ethernet port).
Just install the program. After starting the application, use this server to connect:
After the connection is established, the client asks for your username and password:
- Username: (Your Windows username)
- Password: (Your Windows password)
When done, you should be able to connect to the inter- and intranet as usual.
Cisco VPN Client (outdated)
The following steps have to be taken to establish a VPN connection with the FH JOANNEUM network:
- Install VPN client software
- Download and install suitable VPN profile(s)
- When at home: connect to the internt
- When on location at the FH JOANNEUM: connect to the wireless LAN - see below!
- Start the VPN client and connect with a suitable profile
If everything went fine, you will be asked for a password:
- Username: technikum\(your username)
- Password: (your Windows password)
Afterwards, access to the intra- and internet should be possible. It is recommended to manually disconnect the VPN connection before putting your computer into standby, because connection difficulties might result after wakeup.
Alternative WLAN access point for the old Cisco VPN Client
Besides the known (and visible) access point "wpa4fh", there is another wifi network with hidden SSID broadcast, that can be used with the old Cisco VPN Client to connect to the intra- and internet. On older computers which do not support WPA-Enterprise or 802.1X authentification, this is the only way to get wireless access.
The SSID of the wireless VPN access points is hidden - you have to add the network manually with the following data:
- SSID: wireless4fh
- Protection: none
This wireless network is not directly connected to the intra- or internet - it only serves as VPN access point. All other routing is disabled until your VPN tunnel is established.
VPN client software
VPN client software is needed to establish an encrypted VPN tunnel. This software also needs to be compatible with VPN 3000 Concentrators - Cisco provides their own proprietary client for this purpose.
This is the original proprietary Cisco VPN Client software.
Max OS X
The original Cisco VPN Client is also available for multiple versions of Mac OS X. The user interface is the same as on Windows and the profile import also works identically.
- vpnclient-darwin-4.9.01.0090-universal-k9-BETA (Readme) - From OS X 10.5
- vpnclient-darwin-4.9.01.0030-universal-k9 (Readme) - OS X 10.4, Universal Binary
- vpnclient-darwin-4.8.00.0490-GUI-k9 (Readme) - Old version, until OS X 10.4, PPC
VPNC has been reported to work with Cisco VPN 3000 concentrators. Instructions as well as needed tools can be found on their website.
The VPN client needs connection details, which are contained in profile files. Depending on your location (at home or at one of the FH JOANNEUM locations), you need different profiles:
- Profiles for acces from a remote location
- Profiles for access via WLAN in Graz
- Profiles for access via WLAN in Kapfenberg
- Profiles for access via WLAN in Bad Gleichenberg
- Unpack the profile(s)
- Start the VPN client
- Press the Import button and select one profile at a time.
Right-clicking any profile entry after import gives you the option to set this entry as default. Doubleclicking a profile tries to connect.


Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad).
Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables.
When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125).
Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called "hybrid", accept different types of connectors (FC to SC, LC to SC, etc.). When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.

GCSE Science - Physics – Sound and Sound Waves
KEY STAGE 4 – GCSE Physics Revision Guide
Then use this Revision Guide to remember all the Key Study Points and get Full Marks in your GCSE Physics Exam.
What is “Sound”?
When something (like a speaker) vibrates, it produces sound waves.
Sound waves are longitudinal waves produced by vibration
Note: Longitudinal waves vibrate in the same direction as they travel!
Sound waves require a medium to pass through (they cannot travel through a vacuum)
Sound waves can travel through solid, liquid or gas and do so at different rates:
Sound waves can bounce off other objects and produce echoes
Why do we hear different volumes and tones of sound?
This depends on two things:
the amplitude (loudness) of the sound waves, and
High-Amplitude = High-Volume
Two sounds with the same frequency, but different amplitudes, will sound the same (pitch), but different volumes/loudness.
On the other hand:
Two sounds with the same amplitude, but different frequencies, will have different pitches, but will sound just as loud as each other.
How is Frequency measured?
The most common unit of measure for Frequency is the Hertz:
Number of waves per second = Hertz
What range of frequencies can humans hear?
From 20 Hertz to 20 Kilohertz
Remember: 1 Kilohertz = 1,000 Hertz
Human audible frequency range (decreases with age):
20 HERTZ ——————————————————————————————————-20,000 HERTZ
Above 20,000 Hertz is the Ultrasonic range.
How fast is the “Speed of Sound”?
This depends on the medium that the sound waves are travelling through:
AIR = Three hundred and forty metres per second (340 mps)
WATER = Fifteen hundred and sixty metres per second (1560 mps)
STEEL = Five thousand metres per second (5000 mps)
What is the Speed of Light?
Approximately 300 MILLION metres per second (300,000,000 mps)
That is why you can see a lightning flash/bolt and then hear the thunder afterwards.

This section describes some FactoryStudio deployment scenarios. Large applications can use a combination of those scenarios, or interconnect remote sites, or use the EdgeHMI or IIoT Gateway products to publish data to the main server.
FactoryStudio modules such as Scripts, Device, Historian or Database can be placed on different computers, in a distributed system context. The same concept applies for the many options of client visualization tools, which can run locally at the server computer or remotely.
Therefore there are many possible deployment configurations. The basic ones are described here.
Distributed Data Acquisition System
Client and Server System
Distributed and Redundant Control System
Data Connection with remote sites
FactoryStudio was architected to enable its use in different scenarios and topologies, from a local interface on an embedded panel to fault-tolerant servers, serving multiple projects and clients. The development tools and project components are scalable, reusable and consistent.
The 100% managed code implementation provides unmatched operational stability, thanks to an intrinsically safe software architecture, including execution threads isolation, exception control, failure recovery, modular implementation, hardware abstractions and operating system independence.
Highly flexible, scalable and simple to use
Access data remote machine data, from anywhere, anytime.
Tatsoft provides a flexible and simple licensing model, allowing solutions that size your project to provide the best possible return of investment on each application scenario. The product families and models enable you to deploy high quality and cost-effective systems, ranging from local HMI, touch- panels, embedded systems, supervisory stations, SCADA and distributed systems, control room and operations centers.
For high availability systems, the real-time database, Alarm and Historian servers, data- acquisition, all FactoryStudio components can be deployed as a redundant hot-standby system, with no project changes required.
In this system, the server side components (Data acquisition, Alarms, data logging) and the client side components (displays, client-side scripts) are running on the same computer.
The computer can be windows desktops, Panel PC, industrial PCs, Linux devices, embedded systems. The stand-alone systems can also act as data publisher to remote FactoryStudio servers acting as Edge data collectors.
In the Control System it is possible to have multiple servers in different plants (different projects) in a distributed architecture. This configuration allows access in a control room to any of these plants through specific clients. It is important to mention that the clients of the plants will not be integrated in one machine, so it is necessary to specify which plant users want to watch.
In this scenario, the system is organized in discrete locations controlled by local operators supported by local redundant servers. At the same time, a management level in a central control room can be configured to monitor all sites simultaneously. Each site is represented in the project as a separate cluster, grouping their primary and standby servers.

The ease with which call flows can be created and customized in a virtual PBX has revolutionized the way businesses handle their communications. In this essay, we will explore the reasons behind the simplicity of call flow creation, its benefits, and the tools that make it possible.
One of the key reasons for the ease of creating call flows in a virtual PBX is the shift from traditional hardware-based systems to cloud-based solutions. Traditional PBX systems often required complex on-site equipment, extensive cabling, and the expertise of specialized technicians to configure and modify call flows. In contrast, virtual PBX systems are hosted in the cloud, eliminating the need for physical hardware and making them accessible through user-friendly web interfaces. This shift to the cloud has made it possible for businesses to set up and manage their phone systems without the need for extensive technical knowledge.
Furthermore, virtual PBX providers have recognized the importance of user-friendly interfaces and have invested in designing intuitive dashboards. These dashboards allow even non-technical users to create, customize, and modify call flows with ease. A typical virtual PBX dashboard provides drag-and-drop functionality, visual flowchart representations, and straightforward configuration options. Users can define call routing, set up voicemail, configure call forwarding, and create interactive voice response (IVR) menus simply by clicking and dragging elements on the screen.
Call routing is a fundamental aspect of call flows, and virtual PBX systems excel in this regard. With a few clicks, administrators can specify how incoming calls should be handled. For instance, calls can be routed based on the time of day, caller ID, or the department or extension dialed. The flexibility and ease of setting up routing rules mean that businesses can adapt their phone systems to match their specific needs and organizational structure effortlessly.
Another valuable feature of virtual PBX systems is the ability to create sophisticated IVR menus. IVR menus are interactive voice response systems that guide callers through a series of options using pre-recorded messages and touch-tone keypad inputs. These menus are widely used for tasks like directing callers to the appropriate department, providing information, or collecting customer feedback. Creating IVR menus used to be a complex and expensive task, but virtual PBX systems have simplified the process. Businesses can now record their own prompts or use professionally recorded messages, then arrange the menu options in a logical sequence through an intuitive interface. This empowers businesses to provide a professional and efficient call experience for their customers without the need for specialized equipment or expertise.
Furthermore, virtual PBX systems often include advanced call analytics and reporting tools that make it easy to monitor and optimize call flows. Administrators can access real-time data on call volume, call duration, call abandonment rates, and more. This data allows businesses to identify bottlenecks, optimize routing rules, and make data-driven decisions to enhance their communication processes continually.
Another reason for the simplicity of call flow creation in virtual PBX systems is the availability of integrations and APIs (Application Programming Interfaces). These integrations enable businesses to connect their PBX with other software and services they use, such as customer relationship management (CRM) systems, helpdesk software, or contact center platforms. By seamlessly integrating these systems, businesses can automate workflows and create more sophisticated call flows. For example, an incoming call could trigger a lookup in a CRM system to display customer information to the agent or automatically create a support ticket.
Furthermore, the rise of artificial intelligence (AI) and machine learning in virtual PBX systems has made it even easier to create dynamic and personalized call flows. AI-powered features like natural language processing (NLP) can be employed to interpret caller intent and direct them to the most relevant department or information. Chatbots and virtual assistants can also be integrated into call flows to handle routine inquiries or provide self-service options, further streamlining the communication process.
In addition to the ease of call flow creation, virtual PBX systems offer several benefits to businesses. One of the most significant advantages is cost savings. Traditional PBX systems required significant upfront investments in hardware and ongoing maintenance costs. Virtual PBX systems, on the other hand, are subscription-based, which means businesses can scale their communication infrastructure without the need for substantial capital expenditures. Additionally, the reduced need for on-site technicians and IT staff to manage the system translates into further cost savings.
Virtual PBX systems also provide greater flexibility and scalability. As businesses grow or adapt to changing circumstances, they can easily modify their call flows to accommodate new departments, remote workers, or seasonal fluctuations in call volume. The ability to scale up or down on demand ensures that businesses can maintain efficient and cost-effective communication solutions.
Another benefit of virtual PBX systems is enhanced business continuity. These systems are typically hosted in redundant data centers, ensuring high availability and minimizing the risk of downtime due to hardware failures or disasters. In the event of a power outage or natural disaster at the business premises, calls can be automatically redirected to alternative locations or mobile devices, ensuring that important calls are never missed.
In conclusion, the ease with which call flows can be created in a virtual PBX has transformed the way businesses handle their communications. The shift to cloud-based solutions, user-friendly interfaces, and advanced features like IVR menus, call routing, and integrations have democratized the management of phone systems.

A space start-up claims to have successfully demonstrated its ability to use ordinary unmodified mobile phones to connect to satellite internet services.
Virginia-based company Lynk sent its “Shannon” satellite into orbit three months ago as part of a carpool mission on a Falcon 9 rocket. After some initial testing, the company said “hundreds “Cell phones in the United States, United Kingdom and the Bahamas were able to connect to the satellite as it passed overhead, as if it were a virtual cell phone tower in the ‘space.
“Basically, our satellite looks like your cell phone like a standard cell tower,” said Charles Miller, co-founder and CEO of Lynk.
Satellite internet is all the rage in the space and telecommunications industry, with companies such as SpaceX, OneWeb, Amazon, Telesat and many others launching or planning large constellations of satellites to provide high speed internet. But all of these services will require some sort of terminal, perhaps similar to a DirecTV satellite dish, to send and receive signals in low earth orbit.
The difference with Lynk, according to Miller, is that with his 1m × 1m satellite, there is no need for a terminal, or even software to download. The service is intended to serve remote areas where a customer’s mobile phone provider, such as T-Mobile or Verizon in the United States, does not have coverage. So, like when you travel to a foreign country and are asked if you want to use a local service with international roaming charges, a similar message appears when you leave the coverage area of a mobile operator. Lynk thus shares the spectrum with the mobile network operator.
In order for everything to work, Lynk had to resolve a number of technical issues, Miller said. The main one was to be able to send uplink signals from a mobile phone to a satellite through the “noise” of other phones. Another challenge was to compensate for the enormous amount of Doppler shift between the satellite and the mobile phone on the ground. Existing phones and mobile networks are configured to accommodate high-speed train speeds, but not orbital speeds. Lynk engineers had to design the technology to allow the satellite to perform this Doppler compensation in space so that the phone “sees” what appears to be a fixed tower.
Lynk starts off small. With a single satellite, coverage is only available for a few minutes per day, over several degrees of latitude. With 10 satellites next year at an altitude of about 500 km, Miller said, the goal is to have coverage for much of the planet every few hours. By 2023, with around 100 satellites, there would be coverage every 5 to 20 minutes. To build a continuous network in real time, it will take 1,500 satellites, he said.
“When people are shown nothing, or a satellite every 15 minutes, we’re better than nothing,” Miller said. “It’s technology that saves lives.”
With limited bandwidth, the service will initially offer text-only messages, focusing on the potential for rescuing users in the aftermath of a hurricane or lost on a mountaineering or sea expedition. there will be enough satellites to serve broadband internet, Miller said. The prices of the service will be set by the operator of the mobile network.
So far, the company has raised $ 20 million, but still has a large chunk of it in the bank. According to Lynk’s research, the average mobile phone used on Earth today is only connected to a terrestrial network about 85% of the time. Thus, up to 750 million people experience disconnection at any given time. This is the market Lynk intends to serve. So far, the company has concluded transport agreements with Aliv in the Bahamas and Telecel Centrafrique in the Central African Republic.
Lynk isn’t the only company working to connect land phones directly to satellites. Texas-based company AST SpaceMobile launched a small test satellite called BlueWalker 1 in 2019, validating its satellite-to-cell architecture. The spacecraft was successful in dealing with communication delays from low earth orbit and the effects of Doppler in a satellite-to-ground cellular environment using the 4G-LTE protocol, the company said.
AST’s next prototype spacecraft, BlueWalker 3, is expected to launch aboard a SpaceX mission from Cape Canaveral, Fla., As early as March 2022. The spacecraft has an aperture of 64 square meters and is designed to communicate directly with mobile phones via standard 3GPP frequencies. .
The company has agreements and arrangements with mobile network operators that collectively cover around 1.5 billion mobile subscribers. Partners in this effort are the world’s leading wireless infrastructure companies, including Vodafone, Rakuten and American Tower.
However, AST has not yet obtained Federal Communications Commission clearance to enter the US market. Previously, NASA had raised concerns about the large size of the proposed satellites, with a hard body radius of 30 meters and a much larger array of antennas. The case remains in abeyance.

electrotonic analysis Steady-state electrotonic features such as local input resistances, current transfer or steady-state synaptic integration can be studied in a simple quick way using the TREES toolbox. Changes in local input resistance can for example be observed in real time while editing the morphology of a tree. These elements are to be extended considerably in future versions. But for more sophisticated analysis we recommend to export to NEURON which can be done by a single click in the user interface.

Pioneer in Mining Technology
02 September 2022
On President Jokowi’s agenda while visiting Tembagapura was to inaugurate the company’s 5G mining technology. The technological advancement is a collaboration between PT Freeport Indonesia and PT Telekomunikasi Seluler and is expected to enhance the company’s safety and productivity.
“Today, we reached a significant milestone by applying the first 5G smart mining technology in Southeast Asia, thanks to the collaboration between PT Freeport Indonesia and PT Telekomunikasi Seluler,” Jokowi said.
Tony Wenas, PTFI’s President Director, explained that while the 5G technology might be groundbreaking in the region, due to its naturally challenging and complex operations, PTFI have developed autonomous technology since 2006. With PTFI now fully producing from its underground mines, the operations require sophisticated technology more than ever to deliver safe production. Combined with avant-garde engineering features, the technological enhancement is expected to control the associated underground mining risks and hazards.
“The 5G technology innovations will enable us to monitor and prevent accidents by optimizing the use of Artificial Intelligence,” Wenas said. “Our underground operations pose a high degree of danger for workers and assets. Thus, we need careful planning, apply appropriate technology, empower and protect our workforce.”

In most circumstances the provision of one mobile phone to a director or employee for private use is exempt from a benefit in kind charge. The exemption covers the phone itself, any line rental and the cost of private calls paid for by the employer on that phone. However there are many types of devices that have telephone functionality which do not qualify as mobile telephones. Until recently HMRC took the view that smartphones were in this latter category
HMRC define mobile phones as an “apparatus designed or adapted for the primary purpose of transmitting and receiving spoken messages and used in connection with a public electronic communications service”. They have now changed their view on smartphones and accept that the fact that a device can also be used for other functions will not prevent it from falling within the meaning of “mobile phone.”
As this is an area of changing technology HMRC have limited this to apply to smartphones as configured and understood at the start of 2012. Employers that provide a smartphone in 2011/12 should treat it in the same way as any other mobile phone moreover they may be able to claim a repayment of class 1a NI contributions on smartphones provided for 2010/11 and years back to 2007/2008. Employees will also be able to claim back any tax that they have paid if their smartphones have been treated as a taxable benefit in kind.
Examples of apparatus that does not fall within the definition of a mobile phone include satellite navigation devices, devices that are solely PDAs and tablet and laptop computers.

We suggest that in most area’s where we have surveyed we can cover 3-4 miles (5 km) from a single gateway. Naturally it depends how built up the area is and very dense trees can have an impact on the gateway receiving the signal.
For more information on this you can read the question about repeaters
Distance has increased significantly over recent years. A lot has been to do with development of communications protocols like Sigfox and Lora. We use LoRa modules as it gives us the best technology available for our types of systems. Importantly the ability to have two way communication with our systems.
LoRa networks are impacted far less by obstacles such as buildings and this gives greater distance. The height of the gateway of course helps but it always surprises our technicians when we get to site about how far away we can be and still get a strong signal. This has at times allowed us to incorporate not only an additional vacuum system but also other services like gravity Pump Stations or low pressure pumps.


How World Mobile works?
Connect the last mile.
Bridge the distance between legacy infrastructure and World Mobile to connect countries. Earn rewards for the traffic processed through your AetherNode.
Power the network.
EarthNodes are defined as the processors of the core logic of the World Mobile Chain. They function as the brain of the system that interconnects all the other types of nodes and are composed of a number of software modules, communicating through a central module called the Internode API.
Other EarthNode modules provide an authentication layer (Decentralised Identity module), a ledger layer (blockchain module), and a telecommunications layer (telecom module). The Decentralised Identity (DID) module provides the interface to a digital ID solution. In the blockchain module, a distributed ledger records all the transactions that take place on the network.
Unlike AirNodes, EarthNodes do not have any geographical restrictions. This means it is possible to run an EarthNode and support the World Mobile network from anywhere in the world.
Run the network.
An AirNode is what provides end-user access to the World Mobile network for calls and data. AirNodes can include various kinds of hardware (could be a Wi-Fi access point, an aerostat or a tower), as their configuration is determined by the needs of each location.
In remote areas, AirNodes will be run off-grid using a solar power system to keep the network running continuously.
World Mobile is a demand-driven ecosystem built on the sharing economy. The goal of World Mobile is to build the largest mobile network in the world, offering universal, affordable, high-quality connectivity at the lowest price and fastest speed. Currently, they aim to connect the unconnected in Africa and beyond. For World Mobile to accomplish these goals, blockchain is implemented in the telecommunications industry. It reduces Capital Expenditure and lowers prices relative to traditional telecom companies. The reduction of CapEx will facilitate reaching the 4 billion unconnected users. Previously, these users could not be served by the telecom industry. Additionally, WMT enables billions of people to access financial services, education, and commerce worldwide.


Bluetooth dating app
If you're still a bit shy, you can text message your "match."The disadvantages as far as we can see are that the profiles are very simplistic and don't offer the depth required for any really sophisticated computer-mediated matching as offered by many of the mainstream dating sites.
This is likely to lead to some level of disappointment and could lead to embarrassing situations where you're suddenly confronted with an ardent new suitor who you're not so keen on.
n TAG-like technology is a killer-app in this environment February 12, 2005 The world of computer-mediated matching services looks set to blossom as wireless technologies become all-pervasive.
We've covered two such ingenious matchmaking services in the last twelve months and now a third with enormous potential has emerged.
The proxidating service is different to both, but has similarities.
To use the service you download the Proxidating software, install it on your mobile, activate the Bluetooth connection and fill in your profile and the profile you are seeking, add a photo of yourself and the message you wish to send.
Based on years of research at MIT's Media Lab, n TAG brings social technology into the business event arena where both host and attendee derive numerous benefits compared to the paper badges of the past.The Proxidating software is now available in a dozen languages and is being released in 20 countries, highlighting the lofty ambitions of developer Kangourouge.The proxidating site is multi-language and allows direct download of the software.The third new such matchmaking service was introduced this week - the Proxidating locality-based matchmaking service for Bluetooth-enabled mobile phone users, offers an interesting new way for people to get together. ), the Proxidating service uses Bluetooth connectivity to make the initial contact and with mobile phone usage now universal in many countries, particularly among the young, socially mobile and technology-savvy group, we think it has anormous potential.To understand the potential of the system, it's probably illustrative to look at the two technolgies in this proximity-matching area that have preceeded it.

Kangourouge is also preparing for the launch of a WAP site that will enable mobile phone browsers to navigate the web site more efficiently and download the software direct to the phone.
