Patent DE-19809834-A1 (DE)
Title: Operating method for bidirectional wireless link between base station and user
Inventor: BOELIKE BERND
IPC: H04L12/28
Filed: 1998-03-02
Abstract: The method involves utilizing measures or components that are dependent on the signal flow direction, to assign frequencies within a single frequency band for both outward and return traffic. A sequence of processing steps is created for execution at the transmitting end, for operations/activities or transmission directions after digitization and before emission. Interactive multiple traffic is provided in the frequency band of the main traffic direction, for both directions of the signal transmission to the user, and from the user in the reverse direction, via a return channel. Measures are used for recognition and separation of the transmit and receive signals, for separating the signal flow directions during the traffic times, in both directions. This is done at least at the transmitting end, when possible, and also at the user's end. The method involves using highly directional antennas to achieve decoupling, in order to recognize or separate the transmit and receive signals, and to separate the signal flow directions. Parts of the known transmission signal are subtracted from the antenna signal in order to recognize and separate the transmit signals, in order to separate the signal flow directions. An Independent claim is included for a broadcasting apparatus.

Title: Method of controlling electron flow in X=ray tube used for diagnosis
Inventor: HELL ERICH DR
IPC: H05G1/50
Filed: 1998-08-05
Abstract: The method controls the flow of electrons in an X-ray tube from a constantly heated electron emitter with associated focusing electrodes to an anode.
