ANTI-ENTRAPMENT SYSTEM

An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned in a jamb portion of the translating device, on the translating device, or adjacent to the translating device. The sensor has first and second flexible conductors...

Beschreibung
Zusammenfassung:	An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned in a jamb portion of the translating device, on the translating device, or adjacent to the translating device. The sensor has first and second flexible conductors separated by a separation distance and a compressible dielectric element interposed between the conductors. The conductors have a capacitance dependent on the separation distance. 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 capacitance sensor, and changes 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.
