摘要： The invention relates to an apparatus for the transmission of data and energy between two objects moving relative to one another about a common axis of rotation. The objects each comprise coils which are disposed opposite and are spaced apart axially with respect to the axis of rotation such that an energy transmission between the coils is possible by inductive coupling. A respective electrode carrier having a respective electrical conductor is provided coaxially to and rotationally fixed with respect to the respective coils, wherein the electrode carriers are disposed opposite and spaced apart axially and the electrical conductors are arranged such that a data transmission between the electrical conductors is possible by electrical coupling. The electrical conductors are circular or part-circular and are concentric to the axis of rotation of the relative movement. In addition, the respective coil windings and electrical conductors are arranged concentric to one another. The respective coil carriers and electrode carriers are formed in one piece and as a respective circuit board. A respective arrangement of conductive material for shielding is provided between the first coil and the electrical conductor coaxial thereto and/or between the second coil and the electrical conductor coaxial thereto. The arrangement for the electrical shielding comprises bores in the circuit board in the radial region between the coil and the electrical conductor in which bores conductive material is located. The invention furthermore relates to a laser scanner having such a transmission apparatus in accordance with the invention.

摘要： A sensor is provided comprising at least one transmitter for transmitting a transmission signal; at least one receiver for generating a received signal from the transmitted signal reflected back by the objects; a base unit; a scanning unit movable about an axis of rotation with respect to the base unit for a periodic scanning of the monitored zone; and a control and evaluation unit for detecting information on the objects with reference to the received signal, wherein an inductive energy transmission unit is provided between the base unit and the scanning unit that comprises a first guide element of the base unit and a second guide element of the scanning unit for guiding the magnetic field of the inductive energy transmission; and wherein the guide elements have an L-shaped cross-section. In this respect, the guide elements are divided into at least two respective guide segments in the peripheral direction.
