3 g wheel chair

The X30 wheelchair has been designed keeping in mind the strain that the physically challenged have to undergo in situation where there is no help in hand. Designed by Danish designer Ulrik Svenningsen, the design helps in reducing the strain in hands, and shoulder which some times leads to injuries to them and also puts the device for long term use and improves comfort and mobility. Also these wheelchairs are strong, long lasting and easier to maneuver while going up the inclined surfaces and ramps etc. and also address the issue of transferring the user to and from the wheelchair. Definitely a touching thought for a practical thought.

introduced us to this new gadget which is a mobile phone concept which can be said to have been picked straight out of the Bond movies! One can wear this gadget around their wrist as a watch, though it is transparent. However the look can be customized with the change of color pattern or placing any picture on the background. A foldable gadget, thereby one can mould the same as per the pocket. Accompanied by a pair of earphones that ensures a surround sound effect, it’s a gadget to look out for!

Mobile Memory Initiative


Enabling a new generation of media-rich mobile products
Consumers will come to expect the High Definition (HD) experience of the living room from the mobile devices they carry everyday. In addition, they'll want features including HD resolution video recorders, multi-megapixel digital still cameras, 3D games, and media-rich web applications. These advanced mobile devices will be capable of encoding and transmitting high definition content directly to HDTVs, home PCs and servers. To pack all that functionality in a form factor that's thin, light and delivered with a pleasing aesthetic presents a tremendous challenge for mobile device designers. Chief among these challenges will be the development of a high-performance memory architecture that meets the power efficiency constraints of battery-operated products.
The Rambus Mobile Memory Initiative pioneers high-bandwidth, low-power memory signaling technologies that can meet the needs of future smartphones, netbooks, and mobile gaming and multimedia products. Technologies developed through the Mobile Memory Initiative will enable future mobile memory architectures capable of achieving data rates of 4.3 gigabits per second (Gbps) at best-in-class power efficiency. With this performance, designers can realize more than 17 Gigabytes per second (GB/s) of memory bandwidth from a single mobile DRAM device.
Breakthrough innovations achieve performance and power efficiency
To achieve a high-bandwidth, low-power memory interface solution, Rambus has developed breakthrough innovations that include:
Very Low-Swing Differential Signaling (VLSD) - combines the robust signaling qualities of a differential architecture with innovative circuit techniques to greatly reduce active power consumption;
FlexClocking™ Architecture - a clock-forwarded and clock-distributed topology, enables high-speed operation and a simplified DRAM interface; and
Advanced Power State Management (APSM) - in conjunction with the FlexClocking architecture, provides fast switching times between power-saving modes and delivers optimized power efficiency across a diverse range of usage profiles.
These innovations and others developed by Rambus through the Mobile Memory Initiative, will provide the foundation for a future mobile memory architecture that offers increased performance, high bandwidth, and superior power efficiency.
Rambus' Very Low-Swing Differential Signaling combines the robust signaling qualities of a differential architecture, demonstrated in our Low Power Initiative, with innovative circuit techniques to minimize power consumption. Using a ground reference voltage mode driver, VLSD enables data rates of up to 4.3Gbps with only a 200mV peak-to-peak differential voltage swing and a common mode of 100mV.
The Rambus Mobile Memory Initiative also showcases the FlexClocking Architecture. FlexClocking architecture is a topology where the clock is forwarded and distributed to both the controller and the DRAM device from a central PLL. Using Rambus FlexPhase™ technology to adjust for any variability between the clock and DQ signals, the FlexClocking Architecture enables high-speed operation without the need for a DLL or PLL on the DRAM device. This simplifies DRAM design and reduces power consumption.
The FlexClocking™ Architecture enables high performance and simplified mobile DRAM design
The third featured innovation of the Mobile Memory Initiative, Advanced Power State Management, builds on the FlexClocking Architecture and innovative circuit design techniques. Advanced Power State Management (APSM) reduces memory system power, optimizes power efficiency across operating modes, and provides ultra-fast transition times between various low-power and active operating modes.
With VLSD, FlexClocking Architecture, APSM and other innovations to be developed through the Mobile Memory Initiative, Rambus provides the foundation technologies for achieving data rates of 4.3Gbps at best-in-class power efficiency. With this level of performance, designers can realize more than 17GB/s of memory bandwidth from a single mobile DRAM device. Through the Mobile Memory Initiative and the architectural solutions that follow, Rambus enables its customers to develop the memory solutions for a new generation of smartphones, mobile gaming, and mobile multimedia products that will enrich the lives of consumers worldwide.
Rambus innovations in today's Mobile Memory
Current generation smart phones offer a rich array of features including email, web browsing, games, music and movies. Making these features possible requires innovations which deliver superior performance and are tailored to the low-power environment of battery operated mobile devices. Mobile memory solutions, such as LPDDR memory, are no exception. Numerous Rambus patented innovations, including many that have already been proven in computer and graphics applications, enable low-power solutions essential to today's mobile applications and are
