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.

Other features include: electrical life of 50,000 cycles; operating force of 250 +/- 100 gf; contact rating of 100 mA @ 30 VDC; contact resistance

Signal Conditioner Connects Directly to two LVDT Transducers

March 12, 2009 12:37 pm | Product Releases | Comments

The Model 4331-200 CellMite LVDT AC (Linear Variable Differential Transformer) Digital Signal Conditioner Board from Electro Standards Laboratories connects directly to two standard AC LVDT transducers and simultaneously generates a serial output for connection to a PC and a +/-10V analog output

Data Center Architecture Handles Hardware and Software

March 12, 2009 11:44 am | Product Releases | Comments

Able to integrate with existing IT and building management systems, APC’s InfraStruXure Central, Capacity Manager, and Change Manager provides a standardized method of integrating rack-level power, cooling, and environmental data and alarms into one centralized system. The architecture correlates the physical infrastructure of the data center “white space” with the supporting building infrastructure, providing the ability to create, store and push the system configuration out to similar APC devices with a Network Management Card.

Compact Supplies Provide 20 W

March 12, 2009 10:53 am | Product Releases | Comments

Measuring 2.64” x 1.57” x 0.73”, the ECP20 Series of AC/DC power supplies from XP Power has an output of 20 W for a power density of 6.6 W/in². Single-output units can deliver voltages of 3.3, 5, 9, 12, 24, 30 or 48 VDC. Dual output models provide ±12, ±15 or ±24 VDC. The no-load power consumption is less than 0.3 W. All versions have a Class II input and a peak load capability that can provide 130% of rated output power for a maximum of 30 seconds.

Intel Science Talent Search 2009 Winners Announced

March 12, 2009 5:07 am | Microchip Technology Inc. | Product Releases | Comments

Honoring the next generation of American innovators, Intel Corporation today announced the winners of America’s oldest and most prestigious pre-college science competition, the Intel Science Talent Search, a program of Society for Science & the Public. Eric Larson, 17, of Eugene, Ore., won the top award, a $100,000 scholarship from the Intel Foundation, for his research project classifying mathematical objects called fusion categories. Eric’s work describes these in certain dimensions for the first time.

Electrode Breakthrough Enables Rapid Battery Recharge

March 12, 2009 4:48 am | Product Releases | Comments

A lithium-ion battery electrode described this week in the journal Nature can deliver electricity several times faster than other such batteries. It could be particularly useful where rapid power bursts are needed, such as for laser weapons or hybrid race cars. Test batteries based on the new electrode--developed by Gerbrand Ceder, a professor of materials science at MIT--can be discharged in 10 seconds.

Global Warming: Science vs. Activism

March 11, 2009 2:03 pm | by by Jason Lomberg, Technical Editor | Blogs | Comments

In 2007, Al Gore shared the Nobel Peace Prize for his efforts to “build up and disseminate greater knowledge about man-made climate change.” In his Oscar-winning documentary, An Inconvenient Truth, Gore screeched, “The scientists are virtually screaming from the rooftops now. The debate is over! There’s no longer any debate in the scientific community about this.”
