Abstract: The present invention relates to a ceiling mounted charging station for charging the battery of an electric vehicle (210) parking on a parking space (200). The charging station comprises a charging arm (120) for connection with the electric vehicle (210). The first end of the charging arm (120) is mounted to a housing (140) of the charging station. A charging interface (180) for connection with a corresponding charging socket (220) of the electric vehicle (210) is located at a second end of the charging arm (120) opposite to the first end. The charging arm (120) is rotatable with respect to the housing (140) between a stored-position and a use-position. The distance of the second end of the charging arm (120) to the ground (250) of the parking space (200) is smaller in the use-position as in the store-position.

Abstract: In a circuit arrangement for analyzing a clocked signal reflected from an object, particularly an optical signal, wherein at least one radiation emitter which, for providing the clocked signal, is connected to a clocking signal generator, and at least one radiation receiver which receives radiation pulses emitted by the radiation emitter and reflected from the object, and a comparator by which the output signal pulses of the radiation are compared with reference pulses whose amplitudes depend on output signals of the comparator, are provided, the reference signal pulses occur concurrently with the radiation impulses received by the radiation receiver and the impulses received by the radiation receiver are compensated for each by a respective internal reference impulse before their analysis in the circuit arrangement.
