COMPRESSIBLE CAPACITANCE SENSOR FOR DETERMINING THE PRESENCE OF AN OBJECT |
摘要 |
A compressible variable capacitance sensor for determining the presence, size, position, and type of an object such as a human body part includes two flexible conductor elements separated by a non-conductive compressible element. The capacitance of the capacitance sensor changes as a function of force applied by an object on the capacitance sensor. A controller senses the capacitance of the capacitance sensor and controls a device accordingly. The device may be a movable closed opening such as a window in which the controller controls the window as a function of the monitored capacitance to prevent pinching of the object. The device may also be a seat in which the controller determines the characteristics of the seat occupant based on the monitored capacitance. |
