Wireless PC Security Lock

Wireless PC Security Lock

A great idea for someone in a public office, working on a laptop in a coffe house or WiFi spot. A small radio transmitter weighing about 9 grams sits in your pocket, a not-much-larger receiver plugs into a USB port, and whenever the receiver can't hear the transmitter which is when the user walks out of range, the computer will lock and then resumes normal operation when they enter the range again.
