Abstract: A device for transporting a sheet (18) to be printed in a printer is described, with a carriage (14) which is designed for receiving the sheet and which can be displaced on a fixed stand (12) perpendicularly to the line direction between a starting position for inserting and removing the sheet and an end position moved into the printer. Mounted on the carriage (14) is a releasable clamping device (26) which comprises a bearing surface (22) for the sheet (18) and a clamping lever (35) spring-loaded in the clamping direction. The latter is provided with an actuating cam (48) which co-operates with a control bar (40) provided on the stand (12), in such a way that the clamping device (26) is opened in the starting position, closes after this starting position has been passed in the direction opposite to the end position and opens again when the carriage (14), coming from the end position, reaches the starting position.

Abstract: An arrangement has peripheral systems such as disc memory controllers or other device controllers used in the field of data technology. This allows a flexible design in such a manner that it is possible to match the controller designed using the arrangement to desired values in a simple manner in terms of performance, that is the throughput and the response time, failure reliability, the capability for expanding from very small to very large systems and the capability for connection to a large number of host systems (HS). The design is based on a specific combination of serial device buses to form ring circuits (RS) and high-performance buses (SPBP; SPBS), for example parallel buses, for linking relevant data transmission controllers (DS).

Abstract: A system for dispensing sheet material such as security documents from one of two sheet compartments to a collecting station is disclosed. The system includes a delivery roller and a stepping motor provided independently for each of the two sheet compartments. The delivery roller associated with each of the sheet compartments draws the foremost sheet from a sheet stack within the respective compartment. The foremost sheet drawn off from the stack is fed to a conveyor roller independently associated with each respective sheet compartment wherein the conveyor roller of each sheet compartment is driven by the stepping motor of the other sheet compartment. The sheet drawn off from the stack is fed to a dispensing conveyor which is common to both sheet compartments. The drive for the system is carried out by the two stepping motors. The motors are operated in opposite directions when dispensing is taking place from each of the sheet compartments.

Abstract: A printer (10) for printing single sheets (126, 128) and at least one continuous paper strip (122) on a printing substrate plane (19), in which a single sheet (126, 128) is led up to the printing station (36, 56) from the operator side by being displaced manually on a feed table (20) and, in said printing station, can overlap the continuous paper strip (122), at least over part of the width of the latter. The continuous paper strip (122) is fed to the printing station (36, 56) from the operating side and the continuous paper feed channel (34) and the single-sheet feed channel (30) are each assigned a driven feed roller (98; 38) of a pair of feed rollers (100; 44). A mating roller (42) that is arranged on a rocker (48) can be pressed optionally against the driven feed roller (98; 38) of the continuous paper feed channel (34) or the single-sheet feed channel (30).

Abstract: By moving the printing head of a printing unit to a position outside the printing area, a paper stop is pivoted into the paper transport path and, by lowering the printing head, a gap is opened both between the printing head and printing abutment and between the paper pressure rollers, the coupling of the printing head to the paper pressure rollers in relation to the lowering movement simultaneously effecting adjustment of the printing head gap.

Abstract: The invention relates to a sheet-extracting device with a cassette for receiving a stack of sheets, and to a method of controlling the pressing force of the stack of sheets against the extracting device. The latter has extracting rollers (16) which are arranged on a floating shaft (34). For its part, the floating shaft (34) is centrally connected in a rationally fixed manner to a drive shaft (18) passing through it. The drive shaft (18) is mounted, by one end (20), in a frame-mounted bearing (21) and, by its other end (62), in a displaceable bearing (64). Acting on the bearing (64) is a force sensor (70, 74, 76) which is intended for determining the pressing force of the stack of sheets (12) against the extracting rollers (16). The pressing force is controlled such that it always moves within a narrow middle range between a minimum and a maximum possible value.

Abstract: Method and arrangement for buffering between two synchronously pulsed devices which transmit and receive data packets of data words, the output being enabled as soon as the number of output clock cycles after the start of a data packet exceeds a start value which is determined in advance by measuring the output clock cycles as a function of the input clock cycles.

Abstract: Linear structures are used to identify persons. In order to be able to combine a multiplicity of such linear structures in a database, their original images are analyzed and reconstructed using orthonormal basic functions. A preferred direction of the linear structure is determined for each pixel. A quality measure is used to evaluate the reliability of the analyzed data. Singularities (SI) and minutiae (MI) are extracted and stored.

Abstract: The method is for non-erasable or non-alterable storage of data records in a device, initialization establishing the format of the data records and determining those data fields by way of which summation is permissible. An initialization character sequence is transmitted that has at least a number and length of the data fields to be stored. The valid initialization character sequence is accepted and executed only once. After acceptance only data records whose coding satisfies the information is accepted.

Abstract: Bus segments are connected using interconnected coupling units that are connected to one bus segment each. The coupling units are essentially similar, and the bus segments respectively use one arbitration procedure. The respective arbitration procedure permits interruption by the respective coupling unit without the coupling unit for this purpose obtaining control over the bus segment connected to it. At most one of the coupling units has a state A authorizing arbitration while all the others have a state B not authorizing arbitration. If a coupling unit is in the state B not authorizing arbitration, it itself interrupts all arbitration on the bus segment connected to it without for this purpose obtaining control over just this bus segment, and transmits at least one request at least to the coupling unit in the state A authorizing arbitration.

Abstract: In a memory device for storing data according to the FIFO principle, an input counter is provided having a value which is modified when data are written into a memory, and having a comparison unit that outputs a status signal concerning presence of data in the memory dependent on a comparison of the counter states. A scanning unit is arranged at the connection between the comparison unit and the input counter. The scanning unit scans the state of the input counter according to a clock signal and outputs the scan result to the comparison unit.

Abstract: The method is for coupling segments of a bus system having data and control lines by transmission of bit packets with a predetermined number of bits per packet, which number is less than the sum of the data and control lines. The bit packets contain an indicator to distinguish between data packets and control packets, data packets transmitting the status of the data lines and control packets transmitting the status of control lines. A bus status is formed from the status changes of the status lines. The control packets contain an indicator which selects one of at least two transmission modes in a first transmission mode, the reception of data packets influencing only data lines, and in a second transmission mode, the reception of data packets also influencing control lines, which are defined by the respective bus status, in addition to the data lines.
