    • An obstacle detection system includes a first component and a second component. The motor is configured to move the second component toward the first component. Radio frequency identification tags (RFIDs) are connected to one of the first component and the second component. A controller is operatively connected to the motor and has a transmitter operatively connected to the other of the first component and the second component. The transmitter is operable to create a magnetic field between the first component and the second component. Each of the RFIDs is operable to provide a respective signal in response to the field. The controller is configured to modify power delivery from a power source to the motor when the respective signals received by a receiver change due to at least a portion of the magnetic field being at least partially blocked or attenuated. A method of detecting an obstacle is also provided.
    • 障碍物检测系统包括第一部件和第二部件。 电动机被配置成朝向第一部件移动第二部件。 射频识别标签(RFID)连接到第一组件和第二组件之一。 控制器可操作地连接到电动机并且具有可操作地连接到第一部件和第二部件中的另一个的发射器。 发射器可操作以在第一部件和第二部件之间产生磁场。 每个RFID可操作以响应于该场提供相应的信号。 控制器被配置为当由于至少部分磁场被至少部分阻塞或衰减时由接收机接收到的相应信号改变时,修改从电源到电动机的功率传递。 还提供了一种检测障碍物的方法。
