Abstract: Moisture detection permits moisture removal equipment, such as automotive windshield wipers and defogger systems, to be operated automatically. A system for detecting moisture on a surface includes a light emitter directed at the surface. The presence of moisture is based on the intensity of light from the emitter reflected by the surface and received by a light sensor. The light sensor accumulates charge in response to incident light over a variable integration period.

Abstract: A package that encapsulates an integrated circuit optical sensor and mounts on a support substrate includes a base substrate constructed of an insulating material. The optical sensor bottom surface is bonded to the base substrate top surface. Conductive strips on the base substrate top surface extend from a region near the optical sensor to an edge of the base substrate top surface. Wires are bonded on one end to a sensor bonding pad for which connection is desired and on the other end to a corresponding conductive strip. A window is bonded to the base substrate top surface in a spaced-apart relationship using seal material extending around the sensor enclosing each wire bond. Various means are provided for connecting each conductive strip to a corresponding trace on the support substrate. An electrochromic variable attenuator may be formed on the window, allowing control over the intensity of light striking the optical sensor.
