<p>A safety ski binding includes a first jaw which is fixedly mounted on a ski and a second jaw which is supported movably on the ski and includes an electrically activated release mechanism. A piezoelectric sensor is provided on each jaw, the sensor in the first jaw being wired to a signal-processing circuit provided in the ski and powered by a battery provided in the ski. An electromagnetic coupling is provided to couple the circuitry in the ski with and to provide power to the release mechanism and sensor in the second jaw. Signals from the sensor in the second jaw are transmitted to the signal-processing circuit through the electromagnetic coupling. The signal-processing circuit evaluates the signals received from both sensors and, when a release is required, sends a signal through the electromagnetic coupling to activate the release mechanism.</p> |
