Abstract:
1. An anti-entrapment system for preventing objects from being entrapped by a translating device, the system comprising: a capacitance sensor positioned adjacent to a translating device, the capacitance sensor having first and second conductors separated by a separation distance and a compressible dielectric element interposed between the conductors, the conductors having a capacitance dependent upon the separation distance, wherein at least one of the conductors includes a dopant added to a portion of the dielectric element so as to form a conductive region on the dielectric element; wherein the capacitance of the conductors changes in response to a geometry of the capacitance sensor changing as a result of at least one of the conductors and the dielectric element deforming in response to a first object touching the capacitance sensor; wherein the capacitance of the conductors changes in response to a second conductive object coming into proximity with at least one of the conductors.
