IndraDrive products from Bosch-Rexroth, with Safety-on-Board, provide reaction times which the company says are 400 times faster than conventional solutions that use contactors to produce a safe stop.
Safety functions can be selected directly at the drive and include functions to achieve safe standstill, safe operational stop, reduced velocity (speed), limited increment, direction of movement, limited absolute position and safe control of protective door. Rexroth's Safe Motion technology is certified according to EN 954-1, Category 3. The IndraDrive with Safety-on-Board is designed in accordance with EN61508 and EN954-1 SIL3 standards.
The drive also offers I/O for the safeguarding logic needed to interface to safety gates, panel switches and interlock switches. The drive units, available as servo or vector, cover an output spectrum from 1.5 to 120 kW. For more information on IndraDrive products, go to http://rbi.ims.ca/4930-533.
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.

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.
