Osram Opto Semiconductors (www.osram-os.com) has developed an optical pumped semiconductor (OPS) disk laser prototype that puts out 8W of 980-nm optical power from 19W of pumping power. This is an order of magnitude more efficient than previous semiconductor lasers. One key to success is highly effective heat dissipation of excess energy from the laser's active area. Osram sees this as a major breakthrough toward consumer uses such as laser television displays.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
