FREMONT, CA – June 5 (SEND2PRESS NEWSWIRE) — TeamF1, Inc. (www.TeamF1.com), the high-performance embedded networking and security software company, and Applied Micro Circuits Corp. (AMCC) (NASDAQ: AMCC), a leading vendor of embedded PowerPC(R) and network processors today announced expanded support of TeamF1’s secure networking solutions on AMCC’s PowerPC family of highly integrated embedded microprocessors. This is the latest milestone in a strategic alliance which combines TeamF1’s expertise in embedded security and advanced networking software with AMCC’s global leadership in embedded PowerPC processors.
The two companies have committed to jointly develop highly integrated, advanced networking and security platforms for OEMs and ODMs in the Wi-Fi(R) and VPN application space. Their partnership focuses on demonstrating optimized hardware architectures and software components designed to leverage specialized hardware resources.
Following the recent successful porting of TeamF1 products on AMCC’s 440GR based Yellowstone evaluation kit earlier this year, TeamF1 has now integrated its secure access point software (Air Secure Access Point or “ASAP”) on AMCC’s “Taihu” development platform – a low-cost, easy-to-use evaluation kit for AMCC’s PowerPC 405EP processor. This new integrated platform consists of TeamF1’s ASAP software, TeamF1’s secure management middleware, AMCC’s PowerPC 405EP based Taihu evaluation kit and a standard off-the-shelf PCI-based Wi-Fi chipset. This pre-validated solution is targeted towards the growing market for low-cost, yet full-featured secure access points and wireless gateways.
TeamF1’s ASAP software provides rich capabilities such as the ability to concurrently support many different generations of 802.11 security technology found in today’s wireless networks — from WEP through WPA, up to WPA2/ 802.11i in either Personal (Pre-shared Key) or Enterprise (802.1X) modes. AMCC’s PowerPC 405EP processor with integrated network connectivity and a 32-bit PCI v2.2 interface, when combined with any standard PCI-based Wi-Fi(R) chipset provides the necessary performance and interface features for a complete cost-sensitive ODM/OEM-ready access point solution. To further assist OEMs/ODMs with production-ready solutions, TeamF1 also offers managed VPN/firewall gateway capabilities with ASAP-enabled wireless connectivity in an easily configurable and re-brandable package.
“We are happy to have reached two goals with this milestone: accelerate production schedules of OEMs and ODMs of feature-rich wireless devices through seamless hardware-software integration, and lower BOM costs by targeting a low-cost hardware platform,” said Mukesh Lulla, TeamF1 co-founder and President. “Our alliance with AMCC continues to lead the market in providing solutions that deliver an optimized user experience, while providing system designers with more choices in hardware platforms.”
“We are delighted to see TeamF1 introduce their Air Secure Access Point software for our low-cost 405EP processor platform”, said Charlie Ashton, Director of Software at AMCC. “While the 405EP is an optimum processor solution for wireless access points, OEM and ODM customers expect to integrate off-the-shelf software into their products. The ASAP software package clearly meets their need for comprehensive software with advanced security features. We look forward to achieving many design-wins based around the combination of our 405EP processor and TeamF1’s ASAP software”.
The two companies will be demonstrating the full range of capabilities of this solution at Computex in the Grand Hyatt hotel, in Taipei, Taiwan from June 6-10, 2006.
This integrated hardware/software reference design providing a complete secure access point solution is available immediately from AMCC and TeamF1.

Hi! In my last video, I tried to make my own wireless lavalier microphone which kind of failed due to the great latency of audio versus video “And here’s how I sound. Isn’t it just a genius design?” But fortunately, Røde microphones came to my rescue and put me out of my misery, providing a shotgun microphone and a wireless lavalier microphone, AND they provided extra to give away to my viewers and patrons at the end of the video back to my lavalier design I realized that the latency was due to the fact that I was using a smartphone as FM receiver the phone audio codecs and software layers at around 300 milliseconds of delay to the audio Using a dedicated FM receiver like this one, which I picked up for around $25 removes the latency see See now there is no latency between the audio and video I can even plug this into the camera Now the radio is plugged into cameras audio input see the quality is not awful and with some design improvements and for around $50 this could be a poor man’s Wireless lavalier But the whole point of using a smart phone was to eliminate the need of an additional receiver and make a cheap and high-quality Solution I almost even started a Kickstarter campaign on it in which case I would have ended up like Musil’s noise canceling system the project died in fetuses stage before I could scam the masses now Let’s see if road can in fact solve my issues mind you I’m not a sound engineer But I’m an electrical engineer which makes me a God A Person God. “I’m gonna make you an offer you can’t refuse.” Oh, that’s a different movie. What am I talking about?! Anyway Let’s see if I can cram all the information and pass it out in a short time My main problem was noise an echo there are two kind of noises in my opinion one of them is this white or pink noise Or static that you hear is this ‘Shhhh” in the background and the other one is environmental noise like cars and stuff I guess you can consider echo as environmental noise too. Fortunately for me The camera’s white noise is so loud you can barely hear the street noise First let’s quickly go over the settings my camera provides Which is a Canon t4i for sound recording it provides three modes auto manual and disabled in auto mode There is a fixed audio gain unless the sound is too loud and the camera drops the gain to prevent audio clipping in Manual mode there is only a fixed gain and the sound could clip if it is too loud when in manual mode you can select The gain that’s suitable for your audio level And then there is a wind filter an attenuator if you enable the wind filter it gets rid of the low frequency Wind noises and if you enable the attenuator it drops the gain no matter what mode you’re in by I’m guessing around 10 to 12 DBS. Now I believe Wireless avalier will provide the best results, but let’s check the shotgun first because it has very good benefits Too let’s check its controls this microphone can power with two double-a batteries, or its own rechargeable battery then there is a power button for gain level you can have 0 DB plus 20 DB or -10 DB if there is low-frequency noise you can cut it off below 75 Hertz or below 150 Hertz you can drop the gain on the right audio channel as a safety measure if you are worried that the sound is too Loud and it might clip. Also you can boost the frequencies above 7 kilohertz if that’s something you want now I want to isolate the noises That’s why I came into my sophisticated sound room which is my closet and also I’m gonna talk softer So you can go ahead and raise the volume and hear the noise better Ok! Oh sorry… No clapping. You may have to change the volume Multiple times during the video to better understand what I’m saying raise the volume now to be comfortable with this What you hear right now is the camera microphone at default settings listen to the noise It’s quite noisy now I have the camera attenuator on You see that the noise is significantly lower, but at the same time my voice is also softer so the signal-to-noise Ratio is around the same if you want to hear me the same you have to change the volume on your side Which returns the noise back to what it was the benefit of this is that now I can talk louder to increase the signal-to-noise Ratio now let’s add the rode shotgun to the mix. Now I added the shotgun at 0 DB listen to the noise It’s around the same maybe a little bit different in spectrum the Wouldn’t go lower than what camera already adds in this mode anyways and my voice is around the same level again if I talk loud I increase the signal-to-noise ratio, this is how I sound with a shotgun and This is how I sound with the camera microphone of Of course you can use an extension cord and bring the microphone closer Which will significantly Increase your sound level because the camera is in auto mode It will drop its gain to prevent audio clipping and that will reduce the noise significantly as long as you keep talking That’s why a wireless lavalier can work better because the microphone sits close to the source Unlike the shotgun sitting at the camera now I don’t know Why somebody would use a -10 DB gain unless you’re in a very loud environment that the background noise is not an issue -10 DB gain would actually hurt the signal-to-noise ratio, so let’s use the plus 20 DB gain. I’ll have to talk very soft Listen to the noise, it’s larger but it’s not huge considering we put 20DB gain on the microphone, this can serve two purposes. One is to pick up sounds from far away. Okay Now I’m around 20 meters away from the microphone and you can still hear me clearly This is due to the great noise performance of the road shotgun microphone 20 DB means hundred times higher voltage level But clearly the noise level hasn’t increased as much. The other use is to put the camera in manual mode and reduce the gain significantly to avoid audio clipping and There is no white noise anymore unfortunately for me my preferred level is +10 DB Which this microphone doesn’t provide separately 10 DB would be louder than 0 DB. So I can keep the camera in automatic attenuated mode. I like the automatic mode because it prevents sound clipping to get to the 10 DB audio You can separate the right channel in post-processing But I hate post-processing and want to minimize it so I made a special cable I put a switch on an audio extension cable so that I can select Microphones either left or right channel and feed it to both my camera’s input channels, so I can pick the 10 DB Let’s try it first. This is my camera’s microphone and default settings which I’ve always used adjust your volume and listen to the noise Now I’m using the shotgun at +10 DB and camera at attenuated auto mode See the noise is significantly lower although it is still there I’m sacrificing a bit of noise performance to keep my beloved’ auto mode my voice is loud and the noise level is much lower than Cameras stupid microphone default settings and what a lot of people do is to play music on their video So it’s almost impossible to hear background noise over the music so that’s another trick But if you’re not afraid of clipping your sound using the microphone at plus 20 DB and Camera at manual minimum gain gives you the best results for white noise Now let’s get to environmental noise straight echo and stuff gain control do Nothing when it comes to environmental noise because it’s already mixed with your voice at the microphone But a shotgun microphone Greatly helps with such a noise because it’s very Directional and Attenuates the echo and noise that comes to the microphone from its sides or behind Unfortunately for me The f**ing window is right by me where the noise comes from and the shotgun can’t do sh** about it That’s why soundproofing your room is very important. Well, I’m stuck here so boohoo. There is a solution which is to bring your microphone close and reduce the game so that your voice is dominant over Everything at the microphone, but unless you’re a reporter You don’t want to carry your microphone around like a dork and that’s when Rhodes wireless lavalier Which is my favorite solution comes into picture the microphone is always closed so your voice is loudest Let’s check some of its features the system comes with a nice lapel microphone transmitter Has a gain of 0 + 10 or + 20 DBS and also a link button a power slash mute button and a channel display the receiver has a gain of 0 – 10 or minus 20 DB power button a nice Status display channel select button and a mute button and of course you plug it into cameras audio input this system only supports one Transmitter so if you want to record more people you have to buy more of these or buy a system that supports multiple transmitters Which becomes very expensive in such application a shotgun microphone becomes very cost effective because you can record as many people as you want The noise performance of the system is very good and similar to their shotgun microphone right now. This is cameras microphone in default settings and this is Road microphone at 0 DB with camera in attenuated auto mode and of course you get the best noise performance with rode at plus 20 DB and camera in manual minimum gain. And with this I can walk anywhere. I want and my sound quality remains the same Ghawu! F**k! Now a few things although keeping the microphone close is good bringing it all the way to your throat hurts the audio quality So keeping it down there makes it sound much better You can attach it on the side, but then if you move your head it will significantly affect the volume Keeping it down there. Even if you move your head. The volume is not affected unless you drop your head like this. Now Let’s check the ambient noise and echo with different setups I’m sitting opposite to the window so that the noise is behind the camera and I And the window to increase the noise also, I change the camera to manual so the gain won’t fluctuate This is the camera microphone, This is the shotgun microphone, And This is the wireless lavalier. Both these microphones have very good performance, and I would say wireless lavalier wins quality just because it’s sits closer Otherwise the shotgun is not far behind. It’s easy to set up and also in some applications like recording multiple people It’s easily ahead either way, I have both. GIVEAWAY TIME! Thanks to Røde I have one of each microphone to give away to my viewers and patrons of course patrons are automatically included And they receive more rewards too. (PLZ DONATE) So if this is something you need make sure to subscribe to Røde Microphones YouTube channel and also leave me a comment So I know you need it. Something like “Put me on the Røde® to success!” or whatever be creative. No bonus points for creativity.


How can attacks on wireless systems be prevented?
IT security expert Timo Kasper will present two lectures on the important subject of RFID and NFC application cryptography at RFID & Wireless IoT tomorrow 2017. At the leading european event for RFID and wireless IoT technologies, Kasper will speak about gaps in security measures, possible avenues of attack, and progresses made in securing RFID solutions.
For every system, there are plausible attack scenarios
Timo Kasper is one of Germany's foremost experts when it comes to attacks on wireless systems: In 2010, he and other european scientists cracked the student card of Bochum University in Germany and proved the existence of security flaws in contactless payment cards. In 2016, Kasper and colleagues demonstrated that millions of cars sold worldwide, including vehicles by VW, Audi, Opel, and Renault, could easily be opened by unauthorized persons through a wireless hack.
"For every system, there are plausible attack scenarios, especially if the systems are not well thought-out," Kasper warns. "Digitization means that in addition to physical attack, digital means of attack have to be covered as well."
Presentation in "Technology & Hardware" Forum: NFC penetration tests
In Forum 1 "Technology & Hardware" on Developer Day, Timo Kasper asks whether contactless card systems provide an effective protection against digital fraud?. He presents the open source test tool Chameleon capable of assessing security aspects in RFID and NFC environments in different attack scenarios. With such test tools, companies can put their security measures to the test.
Presentation in "Wireless IoT" Forum: Security nightmare in the IoT
In Forum 2 "Wireless IoT" on Developer Day, Timo Kasper will speak about potential flaws in IoT device encryption. Wireless embedded devices, such as RFID and NFC tagged objects, are predominant in the IoT. In order to protect sensitive data and prevent attacks, many embedded devices employ cryptographic algorithms and authentication schemes. In the past years, various vulnerabilities have been found in commercial products that enable to bypass the security mechanisms. How can companies and consumers defend themselves?
On Developer Day, Technology is Key!
On Wednesday, September 27, RFID & Wireless IoT tomorrow 2017 kicks off with Developer Day: The leading European RFID & wireless IoT event invites all participants interested in new perspectives. Experience technological innovation from the point of view of the hardware manufacturers for RFID, NFC, BLE, LPWAN, Wifi and more!

Distributed System Architecture
Unlock the power of a distributed system, where multiple components on different machines seamlessly communicate and coordinate actions, presenting a unified and consistent experience for the end user.
In computer systems, our focus revolves around two core functions: efficient data storage and robust computing capabilities. Our ultimate aim is problem-solving, and as the complexity or scale of the challenge rises, the necessity of the utilization of multiple computers/threads takes place.
The two main functionalities of distributed systems:
Every machine collaborates seamlessly towards a shared objective, presenting end-users with unified and cohesive results.
Every machine facilitates resource sharing and communication services for optimal performance with its dedicated end-user.
Three Reasons to Decide to Use Distributed Systems
Horizontal Scalability — Since computing takes place independently on each node, it is effortless to add additional nodes and functionality with low-cost, as necessary.
Reliability — Most distributed systems are fault-tolerant as they can be combined with hundreds of nodes that can work together in the reliable environment. That enables the system will not experience any disrupted operations even in the face of individual machine failures.
Performance —Distributed systems are extremely efficient because of the workloads can be divided and dispatched to multiple machines for optimized performance.
At MINDTRO, we recognize the complexities in establishing a requisite architectural design, software integration, and error recovery for a high-performing distributed system. Rest assured, our expertise and experience empower us to conquer these challenges.
Types of Distributed Systems
Distributed systems generally fall into one of four different basic architectural models:
Client-Server — Clients interact with the server for fetching, formatting, and displaying the data to the end- user. The end-users can also make changes locally in the client-side and commit it back to the server to make for permanent updates.
Three-Tier — Information of the client is stored on a middle tier instead of the client to simplify the application deployment. This architecture model is most common for web applications.
Multi-Tier — Ideal for applications or servers forwarding requests to additional enterprise services on the network, ensuring efficient network communication.
Peer-to-peer — Responsibilities are uniformly distributed among machines in the system, that can serve as either client or server. Therefore, the need for additional machines to provide services or manage resources would be eliminated
In distributed systems, encompassing any machine connected to a network with local memory, communication occurs through message transmission. The advantage lies in the ability to support numerous requests and compute workloads, surpassing the capabilities of a standard single system by distributing requests and workloads effectively

One of our main network providers (AmericanIS) will be performing maintenance on the hardware and software of the equipment to which we are directly attached. This work is to resolve an issue that was discovered after a very brief event last Sunday night.
The event last Sunday night occurred when another customer of AmericanIS produced an extreme increase in load, possibly due to a Denial of Service attack or another unusual event). This negatively affected the SUP720 Route Engine performance in the Cisco 6509's which we are connect to AmericanIS through. This ultimately caused a brief period of packet loss and high latency to our customer's whose traffic flowed through AmericanIS at the time.
The solution is to upgrade the SUP720 Engines to most powerful Route Engines available for the Cisco 6509, the SUP720-3BXL. These engines were already on hand, and this upgrade has already been performed on other routers on the AmericanIS network that your traffic may pass through to different destinations on the Internet. However, we are directly connected to the last two routers to be upgraded.
This upgrade will be performed between 22:00 and 23:59 US/Pacific Time, tonight. (06:00 to 08:00 GMT Nov 11th, 2008)
During this time, the two 6509s will be upgrade one at a time. We are connected to these two routers and using HSRP fail-over protocol, so that there will be only a momentary pause in network traffic through AmericanIS as each router is taken down for the upgrade. Except for the brief pauses, the network is expected to remain up.
This maintenance is being performed by one of our upstream providers. This work is to upgrade their network devices to which we are onnected. The time and nature of the upgrade was chosen by them and not by M5Hosting. AmericanIS has historically provided M5Hosting with very highly reliable and high performance Internet transit service. This upgrade is expected to keep that level of service.
As always your feedback and comments relating to this announcement or the work is describes is encouraged.
UPDATE @ 01:30:
The upgrade being performed by AIS on the AIS network has exceeded their announced time window. There has also been a greater impact on the service than expected starting near the end of their announced window. Their very capable Network Engineers are working diligently to complete the upgrade.
While this is work being performed on a network not in our control, I have been on-site at the data center myself for the duration of the maintenance, and will continue to be for any contingency that may require our action and to get first hand updates and to render updates to you if needed.
The original plan was for very brief interruptions to cut over from one router to another. However, there have been a few periods of packet loss and latency on their network during this maintenance. This has affected our network and service to our customers, some routes are affected less than others.
You are welcome to contact us directly if you have specific questions not otherwise addressed.
UPDATE @ 04:30:
The network upgrade is complete and has been stable for a couple of hours now.


With the advent of advanced and digital technology, disability services are now more accessible, flexible, and affordable. A simple tap or touch of a button from a screen and communication becomes effortless. From entertainment, shopping, to setting up a doctor’s appointment, digital technology is an invaluable breakthrough for people with disabilities.
In this post, you’ll learn some of the ways how technology improves people’s health and disability services. In that way, you become more aware of existing technologies available you and your disabled loved ones can use.
Direct Selection Technology Helps Disabled People Control a Computer
While many disability services are viewed online—such as learning programs valuable for speech therapy and behavior therapy—some people cannot use a computer due to a disability, such as those with upper limb disorders, cerebral palsy, and other bone, muscle, and nerve disorders. Now, disabled people and even senior citizens can use direct selection technologies for communication, exploring the web, and even in social media.
One of the most sought-after direct selection technologies is eye-gaze technology, wherein a person with a disability uses an electronic device to control a tablet or computer by looking at the commands or words on the video screen. A television camera captures the light reflections from the user’s cornea and retina. The computer uses data from the relative position of two reflection changes as the direction of the gaze moves, and the computer executes the chosen command.
Switch-Access Makes Delivery of Disability Services More Convenient
Some types of disabilities don’t allow direct selection methods, and some people find such technology too difficult. A good option is the switch access that can be used to activate different devices to match the motion or movement of the small finger, head, knee, arm, or foot.
Here are the good-to-know facts about switch access technology:
- Disability services and facilities can incorporate switch access so people with disabilities can use this technology to make their lives a lot easier.
- Switch access is recommended for people who have profound motor disabilities. Access to higher technology switches includes electromyography signals or electroencephalogram signals.
- Most switch access devices work by scanning. One good example is the automatic scan for a television, wherein a user activates the adaptive remote control in response to a switch. A light moves between options, such as “Power,” “Channel Down,” “Channel Up,” “Volume Down,” and “Volume Up.”
- A communication device uses a switch to scan between pre-stored messages or letters of the alphabet. An on-screen keyboard on the computer will scan letters or mouse functions, so users can perform any computer function using a single switch.
Use of Speech or Voice Activation Software
Occupational therapists, caregivers, nurses, and other healthcare professionals know the importance of assistive technology to people with disabilities. People who are paralyzed or cannot use their extremities rely on voice-activated software to help attain maximum independence as possible. Even individuals with impaired speech can use some voice recognition devices to express themselves.
Assistive Technology Improves Disabled People’s Lives
The Internet and digital technology have made communication and basic household and work chores accessible and manageable to people with disabilities. Many assistive technologies include helpful disability-friendly features, including keyboard accessibility, alternative text for images, transcripts for podcasts, and more, which also assist people with other special needs and temporary impairments.
Instead of being stumped by the language barrier, assistive technologies minimize room for misinterpretations within conversations, creating less discomfort for disabled people and helping them feel socially engaged to participate in disability services actively.
Here are some examples of assistive technologies for people with disabilities:
- Disability services, such as those applicable for the hearing impaired, have useful applications like ASL Dictionary and Dragon Dictation. The apps help translate English into sign language, making conversation between people with disabilities and an employee possible without an interpreter.
- People who have vision impairments can use gadgets equipped with voice adaption technology. You don’t have to “look” at the computer screen because applications like Voice Brief allow you to “hear” social media feeds and the news.
- People who face speech issues can use assistive technology through applications like TapToTalk wherein users can see an image in a tablet and touch it to speak the words out loud.
People with disabilities usually experience seclusion. With the advancement in technology, people who have cerebral palsy or who are blind can experience conversations with other people. Now, people who have speech impediments can use technology to translate written text into speech. Also, social media apps are now available to simplify communication for those with intellectual disabilities.

Interface Design, Product Strategy, Design System
Role: Product Design Lead
Team: Working with the CEO and 5-8 developers (as the team grew)
Status: Shipped incrementally Mar 2018 — Feb 2020
Signal Messenger (signal.org) is a secure communication platform designed to be as simple and easy to use as possible, without compromising privacy. I joined Signal in 2018 as the first full-time designer, right as Signal received substantial funding for the first time and started to grow.
The challenges Signal faced were significant — it was primarily seen as a niche messenger, used for specific tasks that required privacy. The goal was to shift that perception: like privacy, Signal is for everybody.
To do that, we focused on two things for the first year or so: shipping crucial features, and unifying the design with a focus on simplicity and accessibility. This case study will detail the efforts of the latter.
The first thing we needed to do was build a strong foundation for the design. A unified color and type palette for all platforms was the first step, with a focus on improving accessibility (especially color contrast, which was a problem in the old design). Dark mode was also built into the new color scheme, which was already built into Android and desktop, and came to iOS soon after.
Once the foundation was built, our focus shifted to the message design. At the time each platform had its own unique design for the message bubble and supporting information (read receipt, timestamp, etc). The goal was to unify with one design for all platforms, simplifying both the design and development process, and improving the user experience.
Additionally, during this time we were quickly adding new message types (quoted replies, image albums, link previews, and contact shares all launched during this time) and needed a more robust system to support all the new formats.
The new design system (color, type, grid and message designs) shipped in late 2018, and has evolved since as we shipped new features and continued to improve the user experience.
The user base of Signal has not been disclosed publicly, but growth has been significant. Many publications and influential figures have weighed in:
For years a bare-bones texting and calling app, Signal has increasingly become a fully featured, mainstream communications platform. With its new coding muscle, it has rolled out features at a breakneck speed: In just the last three months, Signal has added support for iPad, ephemeral images and video designed to disappear after a single viewing, downloadable customizable "stickers," and emoji reactions.

102 EA II IDENTIFICATION
amplifier is manufactured in two
different versions, audio and video (surround sound). There are four
variations for audio and two for video. The four audio variations are,
Acoustimass Jewel Cube, Three Room System, and 102EA
II. The two video variations are
non-Jewel Cube and Jewel Cube.
To identify the unit's variation, check the
part number and description on the left
and right input terminal panels. The Jewel Cube versions of the
Acoustimass and video variations will state "Jewel" on the terminal
panels, i.e. BUILT-INvisible Jewel Home Theater. If it doesn't state
that it is a Jewel Cube version on the terminal panel, then it is the
non-Jewel Cube, or Acoustimass-5 cube speaker version.
102EA II System Identification: Part numbers for each variation are as follows:
Video Variation for home theater surround sound
(Jewel Cube and non-Jewel Cube): 172075
Acoustimass (Jewel Cube and non-Jewel Cube):
Three Room System: 175461-02
102EA II AUDIO SYSTEMS INFORMATION
Audio Systems Overview
102EA II, 3 Room and Acoustimass®
Amplifiers are completely
self-contained systems. They include all of the circuitry required to
accept line-level audio sources, to process signals as a two channel/two
room system, and to power a variety of Bose installed loudspeakers
through some or all of the six power amplifiers contained in the
systems. These are audio only systems, and do not process video surround
information. There are two video versions of the BUILT-INvisible
amplifier that include a Videostage®
decoder capable of processing video surround information and driving the
appropriate Bose loudspeakers for home theater use.
The BUILT-INvisible 102EA II, 3 Room and Acoustimass systems have three
stereo inputs, each with differential input circuitry to permit long
cable runs through the home while maintaining excellent noise immunity.
The inputs accept signals from Bose Lifestyle®
Music Centers as well as conventional
audio sources. The three stereo inputs connect to an automatic input
switcher. This switcher enables the amplifiers to function as three
source/two zone systems when used with multiple source components. You
can tailor the operation of the automatic input switching to each
customer's wishes by means of two preset terminals which allow the
installer to determine how the amplifier will behave when presented with
multiple sources. Rooms can be configured to switch to a new source when
it plays, or remain dedicated to a single source. A single source can
play in both rooms, or room 1 can play one source while room 2 plays a
When you install a system with the Bose CD-20 Music Center, the input
switching circuitry should be defeated using the preset terminals
located on the amplifier chassis. This allows full control of source
selection from the CD-20 remote control.
BUILT-INvisible Audio Systems at Turn-on
The system will come up in standby by default when AC mains power is
applied to it as long as none of the turn-on signals listed below are
applied. When the system is in standby, the following conditions are in
- The power amplifiers are off
- The DC voltages at the -8 Vdc and +8 Vdc terminals are active
- The Remote Turn-on terminals are enabled
- The Presets are enabled
- The audio signal inputs are enabled
- The automatic input switching circuitry is enabled
When the system is in standby, it is waiting to sense an audio signal at
one of its audio input terminals or a remote turn-on signal at one of
its remote turn-on terminals. This is the state of operation that the
system is normally in as installed when not in use. Once a turn-on
signal or an audio signal is applied to the appropriate terminal, then
the system will switch into the correct mode of operation as determined
by which terminal the input is applied to and how the presets are
configured. When the system is in operation, the power amplifiers are
enabled, and the system will produce audio at the correct locations.
HOME THEATER SYSTEMS INFORMATION
Video Systems Overview
home theater is a completely self
contained system. It contains all circuitry required to accept line
level audio sources, to process signals as a two channel, three speaker
music system or as a four channel, six speaker home theater, and to
power a variety of Bose installed loudspeakers.
Surround Processing Circuitry
The system incorporates Bose patented Videostage
surround processing circuitry. It is fully compatible with Dolby
Surround, Dolby Stereo and UltraStereo. Videostage steering logic was
specifically designed for the unique acoustical characteristics of a
home environment. Proprietary Bose processing also allows adjustment of
the width of the center channel for any screen size. This is not simply
the volume of the center channel, but the spatial extent of it as well.
You can create many different types of home theater systems using this
one chassis. Operating the various systems depends on which terminals
you use, which signals you connect, and how you connect them.
The system will come up in standby by default when AC
mains power is applied to it as long as none of the turn-on signals
listed below are applied. When the system is in standby, the following
conditions are in effect:
- The power amplifiers are off.
- Terminals 13 (-8 Vdc) and 15 (+8 Vdc) are active.
- Terminal 4 (home theater mode remote turn-on) is enabled.
- Terminal 12 (audio mode remote turn-on) is enabled.
- Terminals 6, 7, 17 and 18 (audio signal inputs) are enabled.
- Terminal 11 (home theater mode selector) is enabled.
When you power up the system from standby, the origin of
the turn-on signal determines which mode of operation it will enter.
The mode selection of the Home Theater chassis uses a
logic hierarchy. The system switches from standby or audio mode to home
theater mode immediately if there is a signal at any home theater
turn-on terminal, such as the following: - A 5 to 10 Vdc level at the
Remote Turn-on Home Theater terminal at block 4. - An active audio
signal at the Audio for Video Inputs at blocks 6 and 7. - A baseband
video signal (video, blue screen or snow) at the Home Theater selector
input at block 11.
The chassis will not switch back to audio mode until
there are no longer any home theater mode turn-on signals present. For
example, if the VCR is providing audio to the Left and Right Audio for
Video Inputs at blocks 6 and 7 when you put the audio source into play,
the system will not enter audio mode. It will not play the audio source
until you turn the VCR off. If you turned on the system in home theater
mode, you must remove whatever signal turned it on before you can revert
to audio mode.
home theater system is an audio system by default. It will play audio
until you tell it to operate as a home theater. For example, if a CD
changer is providing audio throughout the home and you connected its
signal to terminals 17 and 18, the system will operate in audio mode. If
any one of the three home theater mode turn-on signals listed above
becomes active, the system will switch to home theater mode. When the
system is in home theater mode: - The Left and Right Audio Inputs at

A jumper from the Delay Disable terminal at block 3 to
Ground at block 1 defeats the four minute time delay incorporated
in the system. This time delay is to prevent the system switching from
home theater mode to audio mode until four minutes have elapsed. This is
to keep the system in home theater mode during the long audio silences
in some movies. Placing a jumper from block 3 to block 1 disables this
time delay, enabling instantaneous switching from home theater mode to
Automatic Turn-on Inhibit Switch
A short placed across these terminals at block 9 will
prevent the system from being turned on under any circumstances. This is
also referred to as a "vacation switch" and is used to allow the
amplifier to be turned off if the residence will be unoccupied for an
extended period of time.

REMOTE MONITORED RSI WIRELESS CAMERA SYSTEMS
At SFS UK Ltd we use the latest market-leading technology to proactively meet our inward-outward security approach.
Most outdoor sites are uncontrolled environments; Our RSI Wireless Camera video verification systems prove vital in eliminating costly false alarms and detecting potential threats for industrial, commercial, and residential sites.
Using this technology allows us to provide cost-effective solutions to your security. RSI enables both robust, reliable, and flexible protection solutions in remote areas where no mains power is available. It can be used as a standalone system, as a cost-effective measure to reduce physical manpower or as an extremely effective additional measure to bolster our layered security ethos.
WHAT ARE THEY?
RSI Wireless Camera Systems are wire-free intruder alarm systems with integrated video verification which on activation, records and transmits a 10 seconds video alarm clip to an Alarm Receiving Centre (ARC).
The system connects to an ARC via 2G/3G technology. This means wherever there is a mobile phone signal, RSI can operate. Battery life for all devices, including the control panel, is up to 4 years. A variety of control panels are available for single (GPRS) or dual path communication (GPRS/IP) back to the ARC depending on the requirement.
HOW DOES IT OPERATE?
Each wireless RSI Outdoor Motion Viewer (OMV) combines a static camera, infrared illuminator, and passive detector. Upon activation of the passive detector the camera records and transmits a short (10 second) clip, which is then transmitted to the SFS service partner EMCS ARC as an alarm.
The footage is then observed by the ARC operators and guided by strict Standard Operating Procedures (SOP’s), the EMCS ARC operator will then review the cause of activation and initiate a response accordingly.
This will be:
1.) Activate Audio Warning Device
2.) Deploy Police
3.) Deploy Mobile Response
4.) Alert client POC
WHERE CAN RSI BE DEPLOYED?
RSI is extremely robust and is proven for protecting remote sites, outdoor locations, and assets in harsh environments. Areas where RSI excels in providing the ideal protection to:

To put it in simple words, IoT refers to things that are connected to the Internet. When we think about the internet, we usually visualize a computer, cell phone or tablet with a screen and a mechanical or virtual keyboard, a web browser such as Google Chrome, Safari or Firefox, where you look for web pages and interact with the web. Well, now there is something called embedded computing, which means that a device that you don’t think of as “smart” is now smart because, even though it doesn’t have those elements mentioned above, it is connected to the internet. Just to start with some examples, think about smart watches, smart TVs, and wearables such as a bracelet that tracks the number of steps you take every day and sends that information to the cloud and can be accessed and visualized on an app in your cell phone or from a website; think about smart houses, lamps or air conditioners that use sensors to turn on or off automatically according to the amount of light or the temperature or that can be controlled using an app. We are used now to a printer being connected to a computer through a cable, but a printer that sends a notification when its ink levels are running low and can order a cartridge before it runs out or that can receive printing orders from a cell phone is a smart printer.
IoT connects things, applications, people, devices and data through the internet. It enables remote control of things, interaction with them and integration of multiple devices and apps. The potential growth of IoT is estimated at 50 billion connected devices; a number that exceeds the world’s population. This volume of devices entail a number of challenges. First of all, the development of hardware that is small and powerful enough to process information in an efficient way and perform in a reliable way; the increase of access to fast networks that are capable of handling this huge number of connected devices; cloud storage services that are reliable and secure enough to store the amount of information that will be created by all these smart things; the development of big data to filter useless information and artificial intelligence to process and turn all these raw data into useful information; finally, security, being surrounded by smart devices and things that store information about our health, daily activities, and other sensitive information represents and enormous challenges for people to be willing to trust smart things.
IoT will allow us to monitor complex processes and tasks in real time. This will facilitate data-driven decision-making at all times.
Sensors will allow to monitor and detect a decrease in performance in machines before they turn into failures that can cause a complete stop in a process.
Self-driving cars obviously depend on smart cameras that need to use AI to identify moving objects, calculate the speed and distance of other cars. Even traditional cars that can identify the level of light to turn the lights automatically are already using IoT; systems that monitor the battery charge level, tire pressure can prevent accidents and failures due to lack of maintenance.
In public transport, IoT can provide more security by tracking the location of vehicles, their speed and driving behavior.
Use of Resources:
Connecting information about the use of electricity, water, internet or gas and allowing public utility companies and individual users about their consumption can increase awareness of what appliances or gadgets are responsible for high consumption and have an impact on it.
Sensors that can monitor the environment: light, temperature, humidity and the presence of nutrients in the soil, and regulate the need to water or use fertilizers to optimize the use of water.
Internet of Things combined with Artificial Intelligence can help have more sustainable homes by saving electricity in the use of lighting, heating and air conditioning systems. Smart gadgets and appliances like refrigerators that can use image recognition to help you keep track of the food you have in your refrigerator, coffee makers that start at a programmed time; monitoring security cameras from your cell phone and also controlling access to your home remotely are some of the options that are already possible.
Pace makers that can send data to an app and can identify irregularities in a timely manner.
Sensors that can monitor and store information like temperature, blood pressure, heart beat rate, exercise level, sleep quality and time, et cetera can help both patients and health practitioners have more reliable data to track habits and focus on prevention of disease.
Wearable devices that can detect brain activity and monitor attention and concentration levels to assist instruction in schools.
Monitoring inventories in shops, or even vending machines can increase efficiency and improve sales.
IoT can help monitor seismic activity, drops in temperature, wind speed, humidity among others that can help anticipate earth quakes, volcano eruptions, storms and provide timely warnings to improve reaction times in natural disasters.

Communicating With Farthest Space
How the Deep Space Network receives radio broadcasts from the edge of the Solar System
Spring 2006 | Volume 21, Issue 4
“It’s like watching grass grow,” says Douglas Mudgway, a longtime engineer and now the historian of NASA’s Deep Space Network. “There’s not very much drama attached to a big antenna tracking a spacecraft millions of miles away. You can’t even see it move. There’s absolutely nothing to see except blinking red lights and guys sitting around drinking coffee and wishing they were somewhere else.”
However, millions of dollars, countless hours of human effort, and irreplaceable scientific knowledge all depend on those people sitting in that control room, monitoring the great antenna dishes outside that loom over the desert like ancient monuments. They’re at one end of an invisible line of communication stretching to the edge of infinity. All the magnificent visions of the planets that our unmanned explorers have brought us from the depths of the solar system, every bit of data collected by the Pioneers and Mariners and Voyagers and Cassinis, all of it first reached Earth as a whisper of photons caressing the face of an antenna dish. For more than 40 years now, maintaining that communication has been the mission of the Deep Space Network, a worldwide system that routinely traffics in the weakest, faintest, and longest-distance calls ever.
Before the space age dawned, in the late 1950s, the idea of sending messages between Earth and deep space was the stuff of science fiction and fringe obsessions. But it became obvious that some means of communicating with spacecraft would be needed. The first steps toward it were made by the military, which was working on intercontinental missiles and needed facilities for tracking and guidance.
In the early 1950s the California Institute of Technology’s Jet Propulsion Laboratory (JPL) was developing such facilities at the White Sands Missile Range for the Army’s Corporal and Sergeant missiles. A team of intensely dedicated engineers, led by Eberhardt Rechtin, created a network called Microlock, a series of ground stations featuring ingenious receivers that could compensate for the shifting frequencies transmitted by moving rockets with a technique known as the phase-locked loop. As perfected by Rechtin and his colleagues Richard Jaffe and Walter Victor, the phase-locked loop system would be the key for communicating to the edge of the solar system.
When America began sending satellites into orbit after the shock of Sputnik , in 1957, Microlock was hastily expanded to include tracking stations in San Diego, Cape Canaveral, Singapore, and Nigeria, from which it followed the Explorer satellites. Some of its equipment was far from sophisticated. “We used little hand-held machines to listen to the satellites,” Rechtin recalls.
But the equipment scaled up rapidly. By mid-1958, as the Pioneer space probes were being readied for America’s first attempts to reach the moon, Rechtin and his team were constructing an 85-foot aluminum parabolic dish on government property in the Mojave Desert in California. Named the Goldstone Pioneer station and built by the Blaw-Knox Company, of Pittsburgh, Pennsylvania, it became the first station of Microlock’s successor, which would be called the Deep Space Instrumentation Facility (DSIF).
The Pioneer station was essentially a radio astronomy antenna based on the Cassegrain system, a configuration already used in many optical astronomy telescopes. Incoming radio waves were reflected by a parabolic main dish to a secondary reflector above the center of the antenna, and the subreflector then bounced the signal down to the focal point of the big dish (reversing the process when the antenna was transmitting). Such a design allowed the antenna’s heavy, bulky electronic transmitting and receiving equipment to be conveniently mounted at the structure’s center of gravity. Modified by two JPL engineers, William Merrick and Robertson Stevens, the antenna used a precision servo-controlled drive mechanism to keep itself pointed at a moving spacecraft, while Rechtin’s supersensitive receivers sifted the spacecraft’s faint voice out of the background radio noise of the cosmos.


The majority of offices rely on networked computers to carry
out daily activities. J and J Electrical Services can install
all types of structured cabling in your premises.
Category 5 (cat 5)
Cat 5 is short for category 5 computer network
cable. It usually comprises of 4 twisted pairs of wires (copper)
terminated by RJ45 connectors. The frequencies supported are
up to 100 MHz. The usual use of category 5 cables is for networks
with speeds of 10 to 100Mbps. That is, Ethernet and Fast Ethernet.
Category 5e (Cat 5e)
Cat 5e is an enhancement of a category 5 cable
and supports data speeds of up to 1000Mbps (Gigabit Networks).
Cat 5e cable will support Ethernet, Fast Ethernet, and Gigabit
Ethernet. Cat 5e cables are backwards compatible, meaning
that they can be used in any network instead of Cat 5 cable.
Cat 5e also reduces the Crosstalk (electrical interference),
which enables better quality of signal transmission. Category
5e has also a higher frequency of up to 350 MHz.
Category 6 (Cat 6)
Cat 6 cables are similar to cat 5 but are produced
to higher standards.
Category 7 (Cat 7)
Category 7 like its predecessors is aimed at
higher standards. The main differences are the isolation structure
and connector type.
Why use an electrician to lay your network
Because there are several technical limitations which can
only be known when assessed by a qualified installer –
i.e. the lengths of the cable (maximum 100meters or 328 feet).
