Abstract
An occupation detection apparatus is provided including a conductor, a sensor, and a shielding electrode. The shielding electrode is located between the sensor and the conductor, and the shielding electrode is coupled, through a low impedance, to electrical ground. The conductor potentially represents an electrical potential of electrical ground. The coupling of the shielding electrode to electrical ground mitigates the susceptibility of the sensor to the conductor and other objects having a potential of electrical ground or near electrical ground.
