    Abstract: Computer tomography method in which the summation required for back-projection is undertaken in two stages. After the first stage summation a filtering operation is undertaken. The method is applied to points lying on a surface that is defined by radiation beams lying in parallel planes that join together opposite segments of the helix. Independent claims are included for: (1) computer tomograph apparatus (2) a computer program.

    Abstract: A discharge area (10) of pre-determined gas pressure and two electrodes (11,12) each have an opening set up on the same symmetrical axis (13) and form a plasma (17) in an area of their openings during an increase in voltage as they reach a preset ignition voltage. This is a source of radiation (17') to be generated, triggers plasma ignition and feeds stored energy into the plasma via the electrodes on igniting the plasma. An Independent claim is also included for a device for generating extremely ultraviolet radiation and weak X-rays.

    Abstract: The arrangement has a control unit (1) or master and at least one controlled unit or slave (2) for transferring address, instruction and/or data messages from master to at least one slave and for returning receipt acknowledgments from the slave to the master for each message. The control unit signals error-free message transfer using the acknowledgment signal. The arrangement has at least one slave which suppresses the acknowledgment for at least one message depending only on the selectable parameters of the slave's operating state, even for error-free message transfer. In this case the control unit still signals error-free transfer. The control unit has an evaluation stage in which the absence of an acknowledgment signal for the message is received and processed as an information signal re the selectable parameters of the slave's operating state. Independent claims are also included for a method of transferring address, instruction and data messages and an electronic communications device.

    Abstract: The invention relates to a detector arrangement for the conversion of electromagnetic radiation into electrical signals. The detector arrangement includes sensitive areas (D 1 , D 2 , D 3 , D 4 ), where each sensitive area corresponds to a respective electrical signal, and at least two of the sensitive areas mesh with one another in such a manner that non-overlapping envelopes (C 1 , C 2 , C 3 , C 4 ) of the individual meshing sensitive areas also mesh with one another.

    Abstract: A device for dynamic impedance matching between a power amplifier and an antenna, having a circulator ( 210 ), which routes a signal received from the power amplifier ( 10 ) at a first port via a second port to the antenna ( 30 ) and diverts the signal reflected at the antenna ( 30 ) and received at the second port through a third port; and a controllable matching network ( 24, 240, 250 ); is characterized in that a directional coupler ( 200 ) diverts a proportion of the signal traveling from the power amplifier ( 10 ) to the antenna ( 30 ), from which the magnitude and phase of the signal may be derived, to a signal detector ( 220 ); and the circulator ( 210 ) routes the entire signal reflected at the antenna ( 30 ) into the signal detector ( 220 ); wherein the signal detector ( 220 ) passes the magnitude and phase of both the signal traveling to the antenna ( 30 ) and the signal reflected at the antenna ( 30 ) to a controller ( 230 ), which evaluates the information received from the signal detector ( 220 ) in order to determine the present impedance value of the antenna ( 30 ) and to correct the controllable matching network ( 24, 240, 250 ) having active and passive components in accordance with the determined impedance value of the antenna ( 30 ).
