Abstract

The present invention provides a touch detector for preventing collision involving an electron therapy applicator. A sensor is suspended from a cable wrapped on a system of pulley wheels and attached to a spring. By adjusting the configuration and tension of the cable properly with respect to the weight of the sensor, the detector sensitivity can be made reasonably independent of the direction of the detected force as well as the position of the apparatus.
