Patent DE-19526836-A1 (DE)
Inventor: SCHMIDT HERIBERT DR
IPC: H01M10/44
Filed: 1995-07-22
Abstract: The invention concerns a device (10) for equalizing the charge in two accumulators or power converters (1, 11) connected in series to form a power-storage unit. The device has an inductive element (23) which can be connected in parallel to the accumulators by means of switches (2, 12) controlled by a time-signal generator (4, 14), the inductive element (23) being connected at one of its terminals (22) between the two accumulators or power converters (1, 11) while the other terminal can be connected, by means of two switches (2, 12) associated one with each of the accumulators or power converters (1 and 11, respectively), in parallel to the respective accumulator or power converter (1 or 11). The device also includes a comparator circuit (27) by means of which the voltages of the two accumulators or power converters can be compared with each other or with a reference value. The comparator circuit (27) is connected by control lines to the time-signal generator (4, 14). During a cut-in phase initiated by the comparator circuit (27), only the switch (2 or 12) associated with the accumulator or power converter (1 or 11) with the higher voltage is closed by the time-signal generator (4 or 14) so that, in a cut-out phase also initiated by the comparator circuit (27), the power stored in the inductive element (23) is delivered through the other switch (12 or 2), which is closed during this phase, or through one of two diodes (13 and 3) connected in parallel to the switches (12 and 2, respectively) into the lower-voltage accumulator or power converter (11 or 1). When a circuit of this kind (10) is used with a multiplicity of accumulators (1, 11), the accumulators (1, 11; 1a, 11a; 1b, 11b) whose charge is equalized by one particular charge-equalization device (10) are also each associated with another charge-equalization device (10).

Patent DE-19539733-A1 (DE)
Title: Method of producing index prints
Inventor: DEUTSCH RAINER
IPC: G03D15/00
Filed: 1995-10-25
Abstract: The method involves subjecting the pointwise acquired image signals for the photographs of the non copied originals to image processing before the generation of the index prints. The image processing amplifies the negative effect of the selection criteria on the image result, so that the justification for the selection is detectable even for the reduced images. The lack of focus of the photographs which are not worthy of copying is increased by filtering in a median filter or a combination of four, nine or more pixels to one image point.

Patent DE-19543844-A1 (DE)
Inventor: VUOLTEENAHO MERJA
IPC: H04B1/40
Filed: 1995-11-24
Abstract: The output frequency of a frequency synthesizer (21) in a transceiver according to the present invention is a multiple of a transmission frequency and said output frequency is divided (23) before modulation (at 24) to produce the transmission frequency (fTX). In an advantageous embodiment, the frequency synthesizer (21) produces a frequency that is twice the transmission frequency, which is divided by a divide-by-2 divider (23) to produce 90 DEG -phase-shifted transmission frequency components required by a transmission frequency quadrature modulator (24). A simple, disturbance-tolerant transmitter construction is achieved by means of the present invention. Residual modulation or interference of the received signal caused by coupling of the modulated transmission signal to the frequency synthesiser (21) operating at the same transmission frequency in conventional transceivers is thus avoided. The receiver local oscillator output is also derived from the output of the same synthesiser. <IMAGE>
Patent DE-19546936-A1 (DE)
Title: DC voltage converter
Inventor: MUECK HORST DIPL ING
IPC: H02M3/337
Filed: 1995-12-15
Abstract: A DC push-pull converter is driven by a series regulator to which a comparator is assigned to compare the regulator output signal with a reference value. To this reference value, a load dependent variable is added. The load dependent value is derived from a current sensor in the circuit of the main switch of the converter. The sensor is supplemented by a condenser. The load-dependent value is chosen so that a load-dependent counter-coupling can be obtained to compensate for the internal resistance of the converter, taking the series regulator into account. In the output circuit of the converter there are devices to give delayed connections to the loads.
