    • An occupant detection system and method that uses an isolation assembly to isolate electrically a power supply providing power to a heater element for heating a vehicle seat from a sensing circuit that uses the heater element as an electrode for electric field or capacitance type occupant detection. The isolation assembly includes a common mode choke that by itself provides sufficient isolation when the sensing circuit excitation signal frequency is high enough, and provides switches that infrequently interrupt electrical power to the heater element so a humidity level can be determined using a relatively low excitation signal frequency. Knowing the humidity level is desirable to adjust a threshold use to determine if the sensing circuit indicates that the seat is empty, or is occupied.
    • 一种乘员检测系统和方法,其使用隔离组件来隔离电源,将电力提供给加热器元件,用于从使用加热器元件的感测电路加热车辆座椅作为用于电场或电容式乘员检测的电极。 隔离组件包括共模扼流圈,当感测电路激励信号频率足够高时本身提供足够的隔离,并且提供不频繁地中断加热器元件的电力的开关,从而可以使用相对低的激​​励信号来确定湿度水平 频率。 了解湿度水平是期望的,以调整阈值使用以确定感测电路是否指示座椅是空的或被占用。

    • An input device with a housing which includes a displaceable cover wall attached to a circuit board to which is affixed a displaceable magnetic part, at least one sensor and a microprocessor; a second magnetic part which is permanently fixed relative to the housing cooperates with the displaceable magnetic part and, upon displacement of the cover wall, generates a haptically perceptible force; the position of the cover wall relative to the housing is detected by the at least one sensor in the form of a coil which varies its inductance value in response to the detected magnetic field of the two magnetic parts, whereby the coil is a frequency-determining component of an oscillator.
