Abstract
An anti-entrapment system for preventing an object from being entrapped by a translating device includes a sensor positionable adjacent to or on the translating device. The sensor has a non-conductive compressible jacket with a cavity, and first and second conductors positioned within the cavity opposite from one another. In response to an object pressing against the jacket, the jacket compresses from a non-compressed state in which the conductors are not in electrical contact to a compressed state in which the conductors are in electrical contact. The sensor has a compressible support either inside or outside of the cavity. In response to the object pressing against the jacket while the jacket is compressed, the support compresses to allow the jacket to compress further in order reduce pinching of the object by the translating device when the object is between the jacket and the translating device.
