Abstract
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.
Claims17
Device for wideband transmission of digital signals between at least one first unit and at least one second unit mobile along a predetermined path relative to said first unit, in particular via non-contacting rotary joints, said first unit comprising:
- a data source for generating a serial data stream;
- a transmitter for generating electrical signals from said serial data stream from said data source;
- a transmitter conductor array for transmitting said electrical signals;
- and said second unit comprising:
- a receiving antenna for tapping electrical signals in a near field of said transmitter conductor array;
- a receiver for receiving the electrical signals tapped by said receiving antenna;
- a data sink for subsequent processing of the electrical signals received by said receiver;
- wherein a coding means is provided between said data source and said transmitter, which performs a digital coding of said data stream in such a way that data is transmitted as said digital signals with a minimum of errors via said transmitter, said transmitter conductor array, said receiving antenna, and said receiver.
Method of wideband transmission of digital signals between at least one first unit and at least one second unit mobile along a predetermined path relative to said first unit, in particular via non-contacting rotary joints, said first unit comprising:
- a data source for generating a serial data stream;
- a transmitter for generating electrical signals from said serial data stream from said data source;
- a transmitter conductor array for conducting said electrical signals generated by said transmitter;
- and said second unit movable in an arcuate path relative to the first unit, comprising:
- a receiving antenna for tapping electrical signals in a near field of said transmitter conductor array;
- a receiver for receiving the electrical signals tapped by said receiving antenna;
- a data sink for subsequent processing of the electrical signals received by said receiver;
- wherein a coding operation is performed on signals on a transmitter side, and a corresponding decoding operation is performed on signals on a receiver side, so that a transmission of the signals is improved.
