AutomationDirect offers the Cutler-Hammer Enhanced 50 series of high-performance photoelectric sensors, manufactured by Eaton, which includes thru-beam, polarized reflex, diffuse and clear object models, designed in a rugged industry-standard rectangular package. Available sensing ranges vary from 45 inches to 500 ft. Flexibility of input supply voltages (10-40V dc and 12-240V dc/24-240V ac) and output types (relay, transistor, or solid-state relay) makes system integration easy. Features include light/dark operation selection, gain adjustment and multi-color LED indicators. All sensors are IP67 rated, and are available with a variety of cabling choices, including micro and mini quick-disconnect styles or a 6-ft integrated cable. Matching cables and mounting brackets are also available. AutomationDirect http://rbi.ims.ca/4912-536

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.
