Publication number: 20080011093Abstract: An anti-entrapment system for preventing objects from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device and a controller. The sensor has first and second conductors separated by a separation distance and a compressible dielectric element interposed between the conductors. The conductors have a capacitance dependent upon the separation distance. The capacitance of the conductors changes in response to a geometry of the sensor changing as a result of either conductor or the dielectric element deforming in response to a first object touching the sensor. The capacitance of the conductors changes in response to a second conductive object coming into proximity with either conductor. The controller receives a signal from the sensor indicative of the capacitance of the conductors, and controls the translating device as a function of the capacitance of the conductors to prevent the translating device from entrapping either object.Type: ApplicationFiled: September 19, 2007Publication date: January 17, 2008Applicant: Nartron CorporationInventors: David Shank, Randall Perrin, John Washeleski

Publication number: 20050092097Abstract: 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.Type: ApplicationFiled: August 27, 2004Publication date: May 5, 2005Applicant: Nartron CorporationInventors: David Shank, Randall Perrin, John Washeleski

Publication number: 20050016290Abstract: 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.
