ANTI-ENTRAPMENT SYSTEM
First Claim
1. A sensor comprising:
- a jacket having a cavity;
a dielectric element within the cavity; and
first and second electrical conductors, wherein the conductors are within the cavity on opposite sides of the dielectric element such that the conductors are separated from one another by a separation distance;
wherein the capacitance of the conductors changes in response to an electrically conductive object moving in proximity to at least one of the conductors;
wherein the jacket is attachable to a seal configured to receive a translating device.

Abstract
An anti-entrapment system for preventing an object from being entrapped by a translating device such as a vehicle window includes a capacitance sensor and a controller. The sensor has a jacket with a cavity, a dielectric element within the cavity, and first and second electrical conductors. The conductors are within the cavity on opposite sides of the dielectric element such that the conductors are separated from one another by a separation distance. The capacitance of the sensor changes in response to an electrically conductive object moving in proximity to at least one of the conductors. The controller is configured to control a translating device as a function of the capacitance of the sensor. The jacket is attachable to a seal configured to receive the translating device.
