    • The position and the weight of a person, in particular a person on a motor vehicle seat, is determined. Reflectors are used to reflect electromagnetic radiation from a transceiver. The attenuation of the sensor reflector radiation enables a report on the seat position of a person in the radiation path. An antenna of each sensor reflector is connected to an electrical load assigned thereto, which is dependent on the weight of the person acting upon it. Depending on this weight, weight information about the person is superimposed by the load onto the reflected sensor reflector signal. The reflected sensor reflector signal is received by the transceiver and fed to the evaluation unit after a signal pre-processing, which enables the weight information of the person to be evaluated.
    • 确定人的位置和重量,特别是汽车座椅上的人的重量。 反射器用于反射来自收发器的电磁辐射。 传感器反射器辐射的衰减使得能够报告人在辐射路径中的座位位置。 每个传感器反射器的天线连接到分配给它的电负载,这取决于作用在其上的人的重量。 根据该重量,关于人的重量信息被负载叠加到反射的传感器反射器信号上。 反射的传感器反射器信号由收发器接收并且在信号预处理之后被馈送到评估单元,这使得能够评估人的权重信息。
