In the Internet of Things era, automotive infotainment’s primary role is to intelligently connect the car and all of its subsystems to the driver and passengers’ world; enriching the driving experience and enhancing the safety of the vehicle. Yet the rapid growth in audio and video devices, such as federally mandated backup cameras, lane-departure warning systems, traffic light recognition and collision avoidance sensors, will require more robust in-car networks – as Lucas Merian noted in a Computer World article, Ethernet is coming to cars.

Last Call for Magnetron-Powered Microwave Ovens?

En diciembre 5, 2014 en RF por Barry Manz

When in 1945 Raytheon’s engineer Percy Spencer accidently discovered the potential of RF energy for heating food (or in Spencer’s case, for melting a chocolate bar in his pocket), the device generating that energy was a magnetron. Sixty years later, this venerable “vacuum electron device” is still powering everyone’s microwave ovens, making it the only consumer product still using a vacuum tube rather than a semiconductor for any purpose. However, this last bastion of vacuum tubes in consumer electronics may soon be relegated to history now that RF power transistors have achieved the required RF output power, efficiency, and ruggedness required to replace them.

Sensors Are a Primary Source for Big Data

En junio 19, 2014 en IoT, Sensors por Ian Chen

Consider a conference that is simultaneously transmitted to audiences in three cities. When a presenter asks the audience a survey question, they can respond by simply raising their hands. The total vote is tallied across all three cities and displayed to the presenter and the audience in real time.

New Ultra-Low-Power Benchmark

En junio 4, 2014 en Low Power por John Donovan

As an editor I’ve been on the receiving end of a lot of specmanship, which is why I always look to datasheets, though meaningful comparisons of seemingly similar MCUs between different vendors are hard to construct, especially since overall energy consumption is so application specific. As Markus Levy of the Embedded Microprocessor Benchmark Consortium (EEMBC) remarked to me last week, “Datasheets don’t lie, they just present [information] the way they want to present it.”
