Abstract
A method and apparatus for controlling of ski vibration consisting an accelerator/actuator sub-system attached to the ski and a adaptive vibration control application residing in the user smart-phone and communicating with the accelerometer/actuator sub-system over Bluetooth radio interface is disclosed. The adaptive vibration control application extracts vibration frequencies and amplitudes from signal received from an accelerometer, separates such frequencies according to their types—bending or torsional, and after thresholding and scaling by the ski calibration parameters and by the user desired ski response, apply such signal to the control loop and consequently to the actuators to provide vibration dampening force. In one embodiment, such actuators are attached to the ski, while in another embodiment such actuators are embedded into the ski.
