ABSTRACT:
This invention relates to a device which is either permanently attached or removable to the edge of a material such as a vehicular glass window. This device may be comprised of a converter sub-unit (vibrator) and an amplifying coupler. These elements are arranged so as to propagate mechanical motion generated by the converter sub-unit through the amplifying coupler and into the edge of the attached material. The resulting vibration motion in the material, which could take the form of a longitudinal compression/rarefaction wave, transverse wave, or a combination of the two waveforms, is of a sufficient magnitude so as to cause the adhesive bond between the material's surface and other solid debris, such as ice, to be quickly broken. This allows the debris to fall away while not damaging the material. The vibration motion in the material is also of sufficient magnitude to remove a liquid such as water from the material surface.
