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
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
