Laser beam projector power and communication system

Abstract

A rotating laser beam projector includes a power controller having a micro controller coupled to a laser power circuit which determines whether the laser beam emitted by the projector is rotating or stationary. When the laser beam is rotating, the laser power circuit delivers a first level of continuance power to the laser. When the laser beam is stationary, the laser power circuit delivers a second level of continuance power to the laser which is less than the first level of power. The micro controller communicates messages from the laser beam projector to a remotely positioned sensor assembly by rotating the laser beam at a first speed when no message is to be communicated and rotating the laser beam at a second speed, different from the first speed, when a message is to be communicated. The laser beam projector includes a bridge for delivering electrical power to a pendulum-supported device from a stationary source. A first conductor is affixed to the stationary source and a second conductor is electrically coupled to the pendulum-supporting device. At least one wire is bonded, such as by ball-and-stitch bonding, from the conductor to the second conductor across a gap.
