A communication device for a remote switch has a control device designed to supply a preparatory signal for preparing a transmission process and a transmission signal for starting the transmission process. A memory device is designed to save one structural information and a parameter for different transmission protocols. A processing device is designed to supply data to be sent, read the structural information and the parameters from the memory device in response to the preparatory signal and, based on the data to be sent and the structural information, create a send packet, and output the send packet and the parameter in response to the transmission signal. A transmission device is designed to wirelessly emit a transmission signal representing the send packet with a transmission characteristic defined by the parameter.

Communication devices, radio switch and method for communication

A hinge assembly comprising a hinge and an autonomous remote switch unit. The hinge comprises two hinge parts that are connected by an intermediate joint of which a first hinge part is connected to a stationary component, and a second hinge part is coupled via the joint to a pivoting element, especially a door, to pivot relative to the first hinge part, and the autonomous remote switch unit comprises a radio unit and a generator unit having an actuation element that transmits an opening and closing of the hinge to the generator unit such that the generator unit induces an electrical current pulse to supply power to the radio unit. The generator unit induces an electrical current pulse both during transmission of the opening and closing of the hinge by the actuation element, and the radio unit transmits data when power is thereby supplied.

Hinge assembly

A motor vehicle transmission with at least one sensor (), associated with the motor vehicle transmission, for picking up measurement signals at the motor vehicle transmission and transmitting them by a wireless unit to a transmission control unit () of the motor vehicle transmission. In each case, an RFID-responder () is associated with each sensor (), which transmits the respective measurement signals concerned to an RFID-reader (), associated with the transmission control unit (). The RFID-reader () transmits wirelessly to the RFID-responder (), associated with the sensor () concerned, electrical energy for operating the sensor () and for operating the RFID-responder () associated with the sensor ().
