Inventor: KOELLE ALFRED R
IPC: G06K19/07
Filed: 1987-07-14
Abstract: A reader transmits interrogating rf signals to a transponder including an antenna having a particular impedance. The signals received by the antenna (30) are converted to a direct voltage which is introduced to a first terminal of a switch such as an emitter of a semi-conductor device (42) having conductive and non-conductive states of operation. A second terminal of the switch, such as the base of the semi-conductor device, receives a voltage variable between first and second magnitudes in accordance with a pattern of binary 1's and 0's in a data source such as a read-only memory (ROM). This pattern of binary 1's and 0's is individual to an object identified by the reader 
     The variable voltage on the base of the semi-conductor device causes the emitter-collector current of the semi-conductor device to vary between first and second amplitudes. When this current has the first amplitude, the impedance of the semi-conductor device and the ROM substantially matches the antenna impedance. When this current has the second amplitude, the impedance of the semi-conductor device and the ROM is substantially greater than the antenna impedance. Capacitance (54) may be connected to the collector of the semi-conductor device and the ROM to store energy in accordance with the current flow through the semi-conductor device. This stored energy provides for an energizing of the semi-conductor device and the ROM. A diode (56) may be connected between the emitter and collector of the semi-conductor device to increase the second amplitude of the current through the semi-conductor device.

Filed: 1987-03-10
Abstract: Utilizing different deposition techniques or deposition conditions for the luminescent material and possibly other materials, a radiation conversion screen is formed which has properties which vary in the thickness direction of the layer. Thus, a high absorption, insignificant scattering of light, suitable shielding, suitable light transmission, low structure noise level and a high resolution can be combined in a single layer. For known layers these different requirements lead to compromises, where invariably at least one of the requirements cannot be satisfied as desired.

Abstract: In a circuit for driving an active-matrix liquid crystal (LC) display panel, a control voltage is periodically con­verted from a value corresponding to the ON state of the LC elements to a value corresponding to the OFF state of the LC elements during one horizontal scanning period. Analogue switches (28) connected to source lines of the panel are switched on at the beginning of each horizontal scanning period. After that the corresponding source lines (15) are charged until a voltage corresponding to respective digital data signal samples is reached and the respective analogue switch is turned off. After that the voltage is maintained by the capacitance of the source line and/or an additional sample holder, thereby making it possible to apply to the LC elements an analogue signal based on digital input data signal.
