Abstract
The disclosure generally relates to a method and apparatus for determining if an optical scanner is moving. In one embodiment the method for sensing movement of an optical scanner comprises the steps of providing an oscillating system comprising a flexible member, a magnet coupled to the flexible member, a coil disposed within a magnetically effective distance from the magnet, and sense circuitry coupled to the coil; generating a first electrical signal from the oscillations of the flexible member; amplifying the generated electrical signal; analyzing the first electrical signal to determine if the generated signal is indicative of movement of the optical scanner.
