Walking, Talking Female Robot to hit Japan Catwalk

March 16, 2009 6:38 am | Microchip Technology Inc. | Product Releases | Comments

A new walking, talking robot from Japan has a female face that can smile and has trimmed down to 43 kilograms (95 pounds) to make a debut at a fashion show. But it still hasn't cleared safety standards required to share the catwalk with human models. Developers at the National Institute of Advanced Industrial Science and Technology, a government-backed organization, said their "cybernetic human," shown Monday, wasn't ready to help with daily chores or work side by side with people — as many hope robots will be able to do in the future.

Power Reference Design Delivers High Efficiency

March 16, 2009 5:51 am | Fairchild Semiconductor | Product Releases | Comments

Using a zero voltage switching technique, the RD212 200-W DC/DC converter reference design from Fairchild Semiconductor can operate at an efficiency of up to 94 percent. With user's guide, application notes and schematics, the design uses the FEB212 evaluation board and features the FSFR2100 FPS power switch, PFM controller, and a high-voltage gate driver with two fast-recovery MOSFETs.

Breakthrough For Post-4G Communications

March 16, 2009 5:38 am | Microchip Technology Inc. | Product Releases | Comments

With much of the mobile world yet to migrate to 3G mobile communications, let alone 4G, European researchers are already working on a new technology able to deliver data wirelessly up to 12.5Gb/s. The technology – known as ‘millimetre (mm)-wave’ or microwave photonics – has commercial applications not just in telecommunications (access and in-house networks) but also in instrumentation, radar, security, radio astronomy and other fields.

Reference Design Creates Digital Audio Systems

March 16, 2009 4:56 am | Atmel Corporation | Product Releases | Comments

Addressing the need for increased digital audio functionality in devices, the AVR32 ATEVK1105 Digital Audio Gateway kit from Atmel uses AVR AT32UC3A 32-bit Flash microcontrollers to create systems for digital audio streaming, decoding and playback. The AVR32 CPU’s DSP functionality handles audio decoding and the UC3A handles two audio interfaces with a stereo 16-bit bitstream audio DAC with internal FIR and Comb filters.
