A method for identifying postage meter and monetary value stamping machines from printed patterns thereof includes performing microprocessor-controlled printing processes in the machine for forming a printing pattern including a monetary value stamp, a data stamp and a printing block from stored data and current data only immediately prior to being printed and temporarily storing the printing pattern until being printed. An identification characteristic is imprinted in the open in addition to the pattern to be printed. The temporarily stored printing pattern and the identification characteristic are supplied together to a printer control for generating a final printing pattern.

A position-resolving sensor for detecting individual light flashes with a multiplicity of adjacent light-receiving elements and an evaluating circuit which determines the light-receiving element which is struck by a light flash. The sensor comprises light-receiving elements subdivided into a plurality of groups such that each light-receiving element is exclusively adjacent to light-receiving elements belonging to other groups. Each group of light-receiving elements is associated with a row of light detectors and at least one optical connecting element establishes a light-conducting connection between each individual light-receiving element and light detectors which are selected in accordance with a given code from the assigned row of light detectors. A high solid-angle resolution can be achieved with few light detectors. In addition, that order number of the light-receiving element is read out which has registered the light flash, directly in a digital code.

A circuit for operating recording nozzles in ink mosaic recorders, each nozzle having an associated ink channel cylindrically surrounded by a piezoelectric transducer having a diameter which expands upon the application of a voltage thereto having a polarity which is opposite to the direction of polarization of the transducer and contracts upon the application of a voltage having a polarity in the direction of the transducer polarization, has a charging circuit which connects the transducers in a rest state to a common voltage source having a polarity in the direction of polarization of the transducers so that the transducers assume a state of contracted diameter. The circuit further includes a discharging circuit operated by a control input for each transducer operable for discharging an ink droplet from the nozzles after ink is drawn into the channels by operation of the charging circuit. The charging circuit contains a switching arrangement so that the charging circuit can be interrupted independently of the operation of the discharging circuit.

A piezoelectric drive element which surrounds an ink channel in a writing jet in a mosaic printing device is a winding formed by plies of thin synthetic foil having piezoelectric properties. The plies of the foil contact adjacent plies over large areas of adjacent plies and form a compression chamber in the interior of the winding which surrounds the ink chamber. Application of a voltage of a first polarity to the winding expands the winding and application of a voltage having an opposite polarity then contracts the winding forcing ink out of the chamber for printing. The winding and chamber may be surrounded by a covering of silicon rubber.

A technique of operating a flow line is provided. The flow line includes two or more assembly stations for the assembly of a heavy machine. The technique involves installing a prepared assembly trailer in the flow line before or at a first assembly station. The prepared assembly trailer is connected to at least one flow line tow bar. If the prepared assembly trailer is installed before the first assembly station, then the assembly trailer is moved to the first assembly station. If not, all the flow line assembly trailers are moved to the next assembly station. The steps of moving the flow line assembly trailers are performed timewise stepwise.

An address management unit is provided for the conversion of logical addresses contained in a program into physical addresses for a multi-processor central control unit of a computer-controlled communications switching system comprising a central bulk storage, and additional memories in the processors, and peripheral units, a logical address forms a polysyllable address word of which one address syllable corresponds to the logical starting address of a logical address space and the other address syllable corresponds to the logical address within this logical address space. A special-purpose memory serves the purpose of storing four-syllable words having a long word length which are respectively stored therein under the addresses formed by the one address syllables. The four word syllables each correspond to a specific control signal in which the first word syllable corresponds to the address of the physical address space, the second syllable corresponds to the plurality of physically-present addresses of the physical address space to be selected, the third syllable corresponds to the total physical object to be selected, and the fourth syllable corresponds to respective information concerning access rights, whereby the fourth syllable monitors the access to the unit to be selected in accordance with the third word syllable.
摘要:
A light sensitive detector arrangement contains a plurality of photosensitive detector elements, which in each instance have a multilayer structure of alternating positively and negatively doped photosensitive semiconductor material with a superlattice structure and control electrodes arranged vertically to the semiconductor layers and bordering on them on their front faces. To these a control voltage can be applied in order to control the spectral light sensitivity. An array contains in each case a predetermined number (for example three) of photo detector groups (E.sub.11 to E.sub.mm) of photosensitive detector elements (E.sub.111, E.sub.112, E.sub.113. . . respectively E .sub.mml, E.sub.mm2, E.sub.mm3). The control electrodes of the photo detector elements of each photo detector group are connected to variable voltage regulators (U.sub.1, U.sub.2, U.sub.3). Through the voltage regulators the upper and/or lower limit wavelength (.lambda..sub.o, .lambda..sub.u) of the photo detector elements of the discrete photo detector groups can be set differently and graded with respect to each other. A filter arrangement is provided having high pass or low pass function, the filter edge (.lambda. .sub.F) of which subdivides the spectral range of the discrete photo detector elements of the photo detector groups into an upper or lower effective spectral range (.lambda..sub.F -.lambda..sub.o3, .lambda..sub.F -.lambda..sub.o2, .lambda..sub.F -.lambda..sub.ol). Differential amplifiers can be driven with the signals of the photo detector elements of each photo detector group, the inputs of which can be driven by the spectral signals of the outputs of two adjacent photo detector elements, such that at the outputs of the differential amplifiers differentiable selected spectral signal responses occur.

The invention relates to an image recording sensor (1) with a plurality of photodetectors (15) in a matrix arrangement. The photodetectors (15) are here integrated components of cells (2), which through address lines (PX, PY) can be coupled for the definition of cell addresses. Each cell has at least one capacitor (C1, C2), in which the photocharge of the photodetector (15) can be stored. The resulting capacitor voltage (U1) is compared in a comparator (17) with a reference voltage (U.sub.REF, U2). The comparator is succeeded by an output circuit (18) for the output of a signal to the address lines upon the occurrence of a positive comparison result. All cells (2) can be driven via an external control circuit (4) with groups of common control and check signals. With such image recording sensor (1) no intensity values per picture element are output but only the addresses of the picture elements of interest, in which the intensity value has exceeded a given level, i.e., the intensity equivalent of the reference voltage (U.sub.REF, U2).
