WiTricity Corporation is an American wireless charging technology company based in Watertown, Massachusetts. The Massachusetts Institute of Technology (MIT) spin-off was founded by professor Marin Soljačić in 2007. WiTricity technology allows wireless power transfer over distance via magnetic resonance and the company licenses technology and reference designs for wireless electrical vehicle (EV) charging as well as consumer products such as laptops, mobile phones and televisions.

thumb|Four reclosers on the right side of a substation In electric power distribution, a recloser, also known as autorecloser or automatic circuit recloser (ACR), is a switchgear designed for use on overhead electricity distribution networks to detect and interrupt transient faults. Reclosers are essentially rated circuit breakers with integrated current and voltage sensors and a protection relay, optimized for use as a protection asset. Reclosers are governed by the IEC 62271-111/IEEE Std C37.60 and IEC 62271-200 standards. The four major classes of operating maximum voltage are 15.5 kV, 27 k
