    • A system is provided for detecting the presence of a human in a compartment of a vehicle that comprises a pyroelectric sensor and a control coupled to the pyroelectric sensor. The pyroelectric sensor comprises a first sensing element and a second sensing element. The first sensing element is arranged in an opposed electrical connection with respect to the second sensing element whereby infrared radiation from a human moving within the compartment is selectively detected by one of the first sensing element and the second sensing element, thereby producing an output signal of the pyroelectric sensor. This output signal is received by the control, and the control generates a control signal indicative of detection of a human within the compartment.
    • 提供了一种系统,用于检测车辆的车厢中的人的存在,其包括热电传感器和耦合到热释电传感器的控制。 热电传感器包括第一感测元件和第二感测元件。 第一感测元件相对于第二感测元件布置成相对的电连接,由此通过第一感测元件和第二感测元件之一选择性地检测来自在隔间内移动的人的红外辐射,由此产生 热电传感器。 该输出信号由控制器接收,并且该控制产生指示检测室内的人的控制信号。
