Tank commanders on military night missions want their ground-based target-recognition systems to detect any approaching enemy tanks as soon as possible. "A detection system with an 800 MHz Pentium chip displays the needed image in approximately 65 seconds," says Bruce Draper, a Colorado State University computer science researcher. He and colleagues Wim Bohm and Ross Beveridge are working with the U.S. Army to develop a powerful new Field Programmable Gate Array (FPGA) that is said to be 600 times faster than the 800 MHz Pentium chip. Instead of requiring 65 seconds to identify enemy tanks, Draper says his chip would speed the process to less than a second. "We buy commercially available hardware and build a language compiler for it," says Bohn. "We design the software environment, but at the circuit level." The FPGA increases a computer's speed by reconfiguring the hardware circuits to directly match the needs of given military software programs. The technique is de-scribed as creating programmable hardware by allowing users to repeatedly download new programs directly onto the computer's circuits. The Defense Advanced Research Project Agency funds development of this project. For more information, go to www.cs.colostate.edu.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
