Abstract:
A board for use on snow, comprising:(a) a longitudinally extending structural, flexing body;(b) a sensor coupled to the body so as to flex with the body to produce a sensed electrical signal in response to a vibration produced within the body;(c) a control circuit mounted on the body and electrically connected to the sensor that receives the sensed electrical signal and generates an electrical control signal in response thereto, the control signal having a waveform that is an inverse of the sensed electrical signal and that is proportional to the amplitude and to the frequency of the sensed electrical signal;(d) a piezoelectric material coupled to the body so as to flex when the body flexes, the piezoelectric material being electrically connected to the control circuit so that electrically induced deformation of the piezoelectric material is influenced in response to the control signal to dampen vibrations within the body; and(e) a power supply electrically connected to the control circuit.
