Abstract: A method and system for driving an air core gauge whereby pointer resolution of an air core gauge is improved across a full range of motion. The method including the steps of generating a first gauge control signal responsive to a signal, the first gauge control signal having a first duty cycle corresponding to a first pointer position; generating a second gauge control signal responsive to the signal, the second gauge control signal having a second duty cycle corresponding to a second pointer position; and modulating between the first gauge control signal and the second gauge control signal alternating drive periods to drive the gauge pointer to display an average pointer position.

Abstract: A backlit switch for use on the instrument panel of an automotive vehicle that eliminates virtual images in the line of sight of a vehicle operator. The switch provides a legend which is spaced back from a clear transparent lens element and oriented to have its normal below the normal of the lens element. The lens element provides an actuation surface which is substantially normal to the force exerted by the operator's finger.
