Abstract
An apparatus for clearing water from a window comprises one or more transducers for coupling to a window. Each of the one or more transducers is operable at any selected one of a plurality of different frequencies to generate respective wave-types. A frequency generator () provides ultrasonic drive signals () to the one or more transducers for the plurality of different frequencies. A mode controller () controls the generator () and transducer configuration of electrodes () to apply to the window ultrasonic waves of any selected frequency and wave-type from the plurality of different frequencies and wave-types.
