Raytheon's re-engineered Patriot radar prototype uses two key technologies - active electronically scanned array, which changes the way the radar searches the sky; and gallium nitride circuitry, which uses energy efficiently to amplify the radar's high-power radio frequencies (PRNewsFoto/Raytheon Company)
Raytheon has a new laser-guided, 155mm “Excalibur” artillery shell — with technology that allows the weapon to change course mid-flight — that it’s pitching to the Army and Navy. The dual-mode Excalibur variant called Excalibur S maintains its GPS guidance system but also adds a laser spot tracker which is a seeker that will detect laser energy from a laser designator and guide to that energy spot on a target.

The hardworking "at" symbol that makes our e-mail go has a rich history in commerce and was used almost exclusively by grocers and accountants when it was plucked from obscurity on a teletype machine's keyboard by Tomlinson back in 1971.
