Abstract
A sensor system includes: a housing having an internal wall defining an opening; a transparent window mounted within the opening; a sensor device within the housing and having at least one of a sensor output or a sensor input alignable with the transparent window; a vibration device in communication with the transparent window, where the vibration device is controllable to produce a first sonic movement; where the transparent window is movably responsive to the first sonic movement with a second sonic movement; and at least one damping member located between the transparent window and the sensor device, where the damping member substantially isolates the sensor device from at least the second sonic movement of the transparent window. A method includes determining a cleaning trigger corresponding to cleaning the transparent window; and controlling, in response to the cleaning trigger, a vibration frequency, amplitude, or duration of the vibration device.
