The invention specifies a holding apparatus comprising a support element and a circuit board. A trench for receiving the circuit board is embodied in the support element. At least one first clamping element is arranged on one or both longitudinal sides of the circuit board and/or at least one second clamping element is arranged in the trench. As a result, the circuit board received by the trench is fixed in the trench in a clearance-free fashion.

Holding apparatus

A retaining facility for clearance-free fixing of a printed circuit board onto a one-dimensional curved surface is provided. In the direction of curvature of the one-dimensional curved surface, a tensile or compressive force acts on the printed circuit board or on at least one first connection device connected to the latter, with the printed circuit board being bent and pressed onto the curved surface. In this way the printed circuit board is held solidly and with little vibration on the surface even when acted on by centrifugal forces.

Retaining facility for printed circuit boards on curved surfaces

An apparatus for transmitting data at high data rates, between two systems that move relative to one another is provided. The apparatus includes an optical fiber and an axial module on one of the two systems for the purpose of axial data coupling, using the optical fiber and a lateral module on another of the two systems for the purpose of lateral data coupling using the optical fiber.

Apparatus for transmitting data between two systems which move relative to one another

A transmission device is provided. The transmission device is operable to transmit data between a rotor and a stator. The transmission device includes at least two pairs of transmission units with one transmission unit embodied as a transmitter and one as a receiver.

Transmission device

The invention relates to a method for adjusting an optical rotating data transmission device having two units that are rotatable with respect to each other about a rotation axis, and that each have a coaxial collimator for coupling light in or out, and relates also to an optical rotating data transmission device that is adjustable by means of the method. For an adjustment, a deviation of a light beam from the rotation axis is determined by means of two detectors at different distances, and from this a positional deviation and also a tilt of the light beam is calculated and suitably compensated.

Apparatus and method for adjusting an optical rotating data transmission device

An optical transfer device for transferring optical signals from a moveable part to a stationary part through an optical transfer medium in order to minimize distortions of the optical signal and increase the effective bandwidth of the signal transit path by minimizing and/or maintaining equal alternate optical signal transit paths from the transmitter to the receiver.

Device for optical signal transmission

In a device of the invention for transmitting modulated optical signals between a first unit and a second unit, the first unit is supported to be rotatable relative to the second unit. The device comprises a light guide along a circular track on the first unit, a first light coupler for coupling light into or out of the light guide, and a second light coupler for coupling light into or out of the light guide and disposed on the second unit and movable relative to the means for guiding light. For an achievement of a high quality of transmission, a regulating means for the position of the coupling elements relative to the light guide, or a hydrodynamic bearing means is provided. An optical light-guiding fiber of the invention for conveying optical signals from an optical transmitter to an optical receiver has a light exit face and means for deflecting light emerging from the fiber in a direction that deviates from a longitudinal axis of the fiber.

Optical rotating data transmission device having an unobstructed inner diameter

Devices for providing optical signal transmissions between a transmitter unit and a receiving unit which is mobile relative to the transmitter unit. The units are optically coupled to each other via an optical transfer medium, and thus improve transmission quality by eliminating, or greatly reducing interferences that affect the transmission quality.

Device for the optical transmission of signals

The present invention relates to a communication station (MT; FIGS. ; FIGS. ) including a power supply unit ( &Prime;), a core unit ( ) connectable to the power supply unit ( &Prime;) and constituted by a mechanically rigid assembly ( - - - - ) of all other electrical units of the communication station except for the power supply unit, and a shell unit ( - ) which houses the core unit ( ) and comprises no electrical units of ther communication station. Front and back housings of the shell unit can be exchanged easily, since no electrical connections are necessary to the core unit during the exchange. Thus, differently shaped communication stations can be easily achieved from a variety of differently shaped housings.
