low voltage Power Generation System is a lightweight solution being used by the United States
Army for board vehicle power (OBVP) generation to their Fuel-Efficient
Ground Vehicle Demonstrator (FED). Kollmorgen says the system enables the FED Alpha vehicle to
provide 30kW of power at 28V dc, over a wide engine operating band. Kollmorgen's
low voltage power generation platform consists of flexible power electronics
that support multiple generator configurations and mild hybrid
capability. The generator system used in the FED vehicle is an in-line
ISG 28V dc, 30kW liquid cooled generator with three 10 kW air cooled power
electronics modules, which communicate on J1939 software protocol. The low
voltage platform also includes a belt driven air cooled generator that produces
30kW at 28V dc, utilizing the same controllers as the ISG system.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
