Abstract: An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device. The sensor has first and second conductors separated by a separation distance, a compressible dielectric element interposed between the conductors, and a non-conductive elastomer outer jacket encasing the conductors and the dielectric element. The sensor having a capacitance dependent upon the separation distance between the conductors. The capacitance changes in response to the separation distance changing as a result of the dielectric element compressing in response to a first object touching the outer jacket, and in response to a second conductive object coming into proximity with at least one of the conductors. A controller controls the translating device as a function of the capacitance in order to prevent the translating device from entrapping either object.
