  • Method and system for driving an air core gauge with improved pointer resolution
    Patent number: 5497078
    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.
