Patent ID: 7448341

Claim:
A gauge comprising: a face plate; a plurality of indicators disposed on a front side of the face plate; a stationary laser diode, pointed away from the face plate, for projecting a beam onto the face plate; a sensor disposed to monitor a parameter and output a signal indicating a value of the parameter; a drive system, disposed behind a rear side of the face plate, for rotating the beam from the laser to a position adjacent a specific one of the plurality of indicators based on the signal output from the sensor, the drive system including a rotating reflector rotatably attached to a stepper motor, the rotating reflector for receiving the beam perpendicular to the face plate and projecting the beam at a non-perpendicular angle to the face plate, wherein the drive system is mounted to a first circuit board and the stationary laser diode is mounted to a second circuit board; and a connector mechanically and electrically connecting the second circuit board to the first circuit board.
