Femtocell-enabled home energy management solution

ip.access, the leading developer of femtocell and picocell solutions, and, the pioneer in home energy management systems, have created a demonstration showing how femtocells can be integrated into smart home energy management solutions. 

With femtocell integration, the AlertMe Energy service can automatically detect when phones enter or leave the house and can therefore power down lights, televisions and other home appliances automatically when the house is empty. The service can also switch the services back on again when the residents return.

The ip.access femtocell powered service also enables mobile phones to control electrical devices in different parts of the house using a series of commands and automatic triggers.

Smart energy metering and control is the subject of extensive EU regulation over the coming years, and services such as AlertMe Energy, which allows electrical appliances in the home to be controlled via the Internet, are set to become a part of everyone's lives in the near future.

ip.access has combined the AlertMe Energy service with its own femtocell technology. The solution works by allowing electrical appliances to switch on and off automatically in response to the presence or absence of phones in the home. The "presence" information is routinely gathered by the femtocell but is normally only used to route cellphone traffic and set tariffs.

The AlertMe integration enables this presence information to be used to set personalised light and power preferences which are activated automatically when a subscriber arrives at home. Pre-set electrical outlets can also switch off automatically to save energy a few minutes after the last person has left the house.

The demo also shows how supplementary services codes on the phone can be personalised through the femtocell when the phone is at home, allowing the phone to be used to switch appliances on and off remotely. For example, a subscriber could type *1# on their phone to switch off the downstairs lights and power after retiring upstairs to bed.

"One automatic trigger could be to switch the kettle on as soon as you arrive home," said Dr Andy Tiller, VP Marketing at ip.access. "But there is a lot more to this than just tea and convenience.

"Using a femtocell to personalise supplementary services codes is a new and unique idea," he said. "It enables the mobile phone to become a powerful controller for all kinds of applications in the home. And because it's a network-enabled feature, it works with any handset – there are no applications to install."

According to founder Pilgrim Beart, "The mobile phone is increasingly the remote-control for your life. Most people carry their handset everywhere they go, making it an ideal control device for the AlertMe Energy service. And because everyone already has a mobile phone, there is no extra cost involved."

The demo also shows how the AlertMe Hub (the central device that receives instructions via the Internet and controls the electrical plugs in the home) can be integrated inside a femtocell Access Point, receiving its power and Internet connection through the femtocell. In this way, a mobile operator could offer a smart home energy management solution as an integrated option to its femtocell subscribers.

ip.access will be showing the demonstration at the Femtocells World Summit in London from 22-24 June.

High-speed and low-power electronic circuits on carbon material

Using a heated atomic force microscope tip, researchers have drawn nanoscale conductive patterns on insulating graphene oxide. This simple trick to control graphene oxide's conductivity could pave the way for etching electronic circuits into the carbon material, an important advance toward high-speed, low-power, and potentially cheaper electronics.

Researchers Create Logic Circuits From DNA

Researchers at Duke University recently used DNA to craft tiny chips used in computers and electronic circuits. By mixing DNA snippets with other molecules and exposing them to light, researchers created self-assembling, DNA-based logic circuits. Once perfected the tech could serve as an endlessly abundant, cheap alternative to silicon semiconductors. Chris Dwyer, lead researcher on the project, says that one grad student using DNA to make self-assembling circuits could produce more logic circuits in one day than the global silicon chip industry can create in an entire month!"

GM Develops Augmented Reality Windshield

The entire windshield is turned into a transparent display to highlighting landmarks, obstacles and road edges on the windshield in real-time. Such a system can point out to drivers potential hazards, such as a running animal, even in foggy or dark conditions, GM says. GM uses a special type of glass coated with red-emitting and blue-emitting phosphors--a clear synthetic material that glows when it is excited by ultraviolet light. The phosphor display, created by SuperImaging, is activated by tiny, ultraviolet lasers bouncing off mirrors bundled near the windshield. Three cameras track a driver's head and eyes to determine where she is looking. [Via Technology Review]

Faster Optical Switching Through Chemistry

Specially designed molecules could lead to all-optical data switches that could make the Internet far faster.
New molecules produced at Georgia Tech could enable engineers to build all-optical data routers, ultimately leading to transmission speeds as high as two terabits--or 2,000 gigabits--per second. Today's fastest commercial routers switch data at 40 gigabits per second. Follow the links for more info.

Silicon Brain

Researchers have built a chip with the equivalent of 200,000 neurons and 50 million synapses in an effort to mimic a human brain in silicon.

Although the chip has a fraction of the number of neurons or connections found in a brain, its design allows it to be scaled up, says Karlheinz Meier, a physicist at Heidelberg University, in Germany, who has coordinated the Fast Analog Computing with Emergent Transient States project, or FACETS. A neuron circuit typically consists of about 100 components, while a synapse requires only about 20. However, because there are so much more of them, the synapses take up most of the space on the wafer, says Karlheinz.

Worlds First Satellite-Cellular Mobile Platform Based on SDR Technology

Infineon Technologies, SkyTerra, and TerreStar Networks today jointly announced the worlds first multi-standard mobile platform based on Infineons innovative software-defined-radio (SDR) technology. SkyTerra and TerreStar are both developing next-generation integrated satellite-terrestrial communications networks.

This groundbreaking technology will enable ubiquitous mobile communications coverage from anywhere in North America using mass-market devices costing about the same as terrestrial cellular-only devices. SDR-enabled satellite-terrestrial handsets will operate with multiple cellular and satellite-based communications technologies including GSM, GPRS, EDGE, WCDMA, HSDPA, HSUPA and GMR1-2G/3G. We are very happy to contribute our innovative SDR technology to this exciting new application of integrated satellite-terrestrial mobile devices in both SkyTerras and TerreStars networks, said Ronen Ben-Hamou, Vice President and General Manager of Software Defined Radio mobile platforms in the Wireless Division of Infineon. Together with our partners we leverage the flexibility and efficiency of our SDR technology into this connected-anywhere mobile environment, enabling operators to provide very compelling multi-standard communication devices to even the most demanding end users.

We are very pleased to work with Infineon on the development of an SDR-based chipset platform, said Drew Caplan, Chief Network Officer for SkyTerra. With this agreement, we are taking another significant step toward making combined satellite-terrestrial communications a reality for consumers, enterprise, government and public safety users. We anticipate that this SDR chipset agreement will expand our marketopportunities as well as the range of technologies and potential devices that will be satellite-terrestrial capable, providing consumers with additional cost-effective purchase options. Dennis Matheson, Chief Technology Officer at TerreStar, added: The Infineon SDR chipset is a tremendous addition to our chipset program and greatly expands the universe of devices that will be satellite enabled. In addition, the programmable nature of SDR technology allows for feature upgrades via software and shortest-ever turn-around times for nextgeneration products. We look forward to using this chipset platform to perform additional handset trials on our evolving 4G network. To enable satellite connectivity in the SDR platform, Infineon will integrate GMR1-3G technology furnished by Hughes Network Systems, a market leader for mobile satellite solutions.

About the XMM SDR 200
Infineons SDR mobile platform, called XMM SDR 200, requires only one single baseband device, the X-GOLD SDR 20 and one single RF transceiver, a member of Infineons leading SMARTi family. As X-GOLD SDR 20 also includes all power management functions on-chip, less than half the number of key components are needed compared to previous modem solutions. This platform enables satellite-terrestrial terminals in a small form factor comparable to todays cellular-only mobile phones. The XMM SDR 200 is an extremely cost- and energy-efficient solution, requiring only one dedicated chipset for the two distinct standards. With this platform, Infineon once again demonstrates its capability to provide semiconductor solutions that connect people and increase energy efficiency in electronic devices. First platform samples will be available in Q3 of 2009.

Low Voltage Is Key To Energy-Efficient Chip

News in from the International Solid State Circuits Conference in San Francisco of a new energy-efficient chip designed by researchers at MIT. It's said to be able to run on 1/10 the power of current chips. Texas Instruments worked with MIT on the design, which is maybe five years from production. The key to the chip's improved energy efficiency lies in making it work at a reduced voltage level, according to... a member of the chip design project team. Most of the mobile processors today operate at about 1 volt. The requirement for MIT's new design, however, drops to 0.3 volts.

Intel's Power-Efficient Penryn Processors

Over the weekend Intel launched its long-awaited new 'Penryn' line of power-efficient microprocessors, designed to deliver better graphics and application performance as well as virtualization capabilities. The processors are the first to use high-k metal-gate transistors, which makes them faster and less leaky compared with earlier processors that have silicon gates. The processor is lead free and by next year Intel is planning to produce chips that are halogen free, making them more environmentally friendly. Penryn processors jump to higher clock rates and feature cache and design improvements that boost the processors' performance compared with earlier 65-nm processors, which should attract the interest of business workstation users and gamers looking for improved system and media performance.
