A device for signal transmission in computer tomographs comprising a rotating part supported to be rotatable with respect to a stationary part. A transmission controller is provided on the rotating part for compiling, from video data of a video source and from control information of a control unit, serial data for transmission to the stationary part by means of a rotary joint. A receiving controller is provided in the stationary part for receiving the serial data transmitted by the rotary joint and for evaluating these data and communicating the control information contained therein to a control unit, and the video data to a data sink. The serial data generated by the transmission controller comprise data frames, and video data and control information each being transmitted in a data frame.

摘要:
An inductive rotary joint for non-contact transmission of electrical energy between a stationary part and a rotating part of the rotary joint comprises a power generator for generating an alternating voltage or an alternating current, which feeds a load by means of a rotatable power transmitter. An electrical parameter on the primary side of the power transmitter is determined with a measurement means, and from this, the condition of another electrical parameter at the load is approximated by means of a functional unit. Regulation of the power generator is effected with this approximated value.

摘要:
A device for receiving digital signals comprising at least one receiving antenna, a measuring means for determining parameters of relevance to signal quality, a digitizer, and a signal-processing unit. The signal-processing unit is controlled to optimize the reception of the digital signals on the basis of the parameters determined by the measuring means. A signal-processing unit processes signals from the receiving antenna and a digitizer converts the processed signals so that the converted processed signals can be measured to determine their relevance signal quality; a transmitter conductor array coupled to the receiving unit can be controlled therefrom. Controlling the signal quality occurs using a dielectric or ferromagnetic materials, impedance elements, or actuators between the receiving antenna and the transmitter conductor array.
摘要:
A device for transmission of digital signals between two units movable relative to each other, particularly with non-contacting rotating data transmission devices, comprises an encoder on a transmitter side along a signal path for conforming a coding of the digital signals to transmission characteristic of a transmission path, so that a given spectral distribution of signals is attained. An optional decoder on a receiver side restores original signals, so that the coding remains concealed, but a substantially more reliable transmission is achieved.

A device for the transmission of 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 signal transmission path, so that an optimum transmission is achieved. An optional decoder means on a receiver side regenerates original signals so that the coding remains hidden, but a substantially more reliable transmission is achieved.
