The invention refers to a docking device for the docking of a maintenance device to a nozzle of a satellite, including a distance sensor for determining the distance between the maintenance device and the nozzle of the satellite. Further, a locking device is provided for connecting the docking device with the nozzle of the satellite.

Robust capacitive distance sensor

An assembly for wireless energy communication to an implanted device comprises an external belt () accommodating a wearer control () followed by controller (), a battery pack (), an inverter (), a transmission coil () connected in parallel by a plurality of capacitors, and an infrared transceiver. Provided furthermore is an implanted device comprising a receiver coil () having the same dimensions as the transmission coil (), a rectifier following said receiver coil (), an infrared transceiver () followed by a controller and an sensor assembly () assigned thereto as well as a battery pack () for powering said implanted device via an energy manager ().

According to the invention, in order to suppress a latch-up, the supply voltage is switched off following the detection of a latch-up, charge located in the circuit is reduced with the air of a short-circuiting switch, and the detection of a low voltage is temporarily canceled when the supply voltage is gradually increased again. A protective circuit is assigned to an electronic circuit in order to protect the radiation-sensitive components thereof, the electronic circuit being subdivided into groups of active circuit components accepting a similar amount of current in a predefined area and a protective circuit being assigned to at least one of the groups of active circuit components accepting approximately the same amount of current in a predefined area. In order to prevent the output current from influencing the output voltage, a current-detecting unit is mounted upstream of a voltage-regulating unit.
