Abstract: The invention relates to a device and a method for transmitting digital signals between at least two units disposed to move relative to each other. By combining information signals with random signals, the spectral power density of a signal is reduced for the same transmission power.

Abstract: What is described here is a device for the transmission of modulated optical signals between two units supported for rotation relative to each other, by means of optical transmitters and receivers. The total of optical transmitters and receivers is three at minimum. A switching unit selects optical transmitters or receivers, respectively, for transmission in dependence on the position as well as in a synchronised manner so that the optical path will always have the same orientation as the direction of movement. Moreover, means are provided for suppressing multiply transmitted data.

Abstract: A device for transmitting digital signals between two units mobile relative to each other, in particular via non-contacting rotary joints, comprises a coding means on a transmitter side along a signal transmission path, for matching a coding of the digital signals to transmission characteristics of the transmission path so as to achieve a predetermined spectral distribution of a signal. An optional decoder means on a receiver side regenerates original signals so that the coding will be hidden, but a substantially more reliable transmission is achieved.

Abstract: A device for transmitting digital signals between two units mobile relative to each other, in particular via non-contacting rotary joints, comprises a controller on a transmitter side for controlling an issued data rate or data package size of digital signals according to transmission characteristics of a data transmission path so as to achieve an optimum transmission. An optional analyzer means on a receiver side regenerates original signals so that a conversion remains hidden, but a substantially more reliable transmission is achieved.

Abstract: A data transfer system for the optical transmission of data using an optical waveguide. The emitter and/or the receiver is adapted to be displaced along the optical waveguide or positioned at different sites. The optical data transfer system allows light to be coupled or decoupled by scattering centers at optional positions.

Abstract: What is described here is an arrangement for transmitting electrical signals and/or energy between parts that can be rotated relative to each other, whereof the part (transmitting part) on which the transmitter is disposed comprises at least two electrical conductors whose shape is adapted to the trajectory or path of movement and into which said transmitter feeds the signal to be transmitted in a symmetrical form, while the other part comprises the receiver (receiving part),
