Los Angeles —The figure in the picture is no dwarf. It's a technician at Boeing Satellite Systems (BSS), formerly Hughes Space and Communications Co. BSS is building the 12.25-m (40-ft) reflector designed for geostationary satellites used in regional mobile communications. Known as the Boeing GEM spacecraft, it transmits and receives signals from an L-band feed array, which forms a large number of small spot beams whose position can be adjusted as phone traffic warrants. Composite materials provide a 78-kg (170-lb) reflector that compresses into a 1.3-m (50-inch) diameter 3.8-m (150-inch) long package for launch. The first GEM spacecraft is the Thuraya-1 satellite, which will be part of a mobile satellite system including the Arab world, Indian subcontinent, Central Asia, and eastern Europe including Turkey.
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.
