Abstract: For the automatic evaluation of the transmission quality of a voice signal that is transmitted by a digital transmission system (1) frequency components that correspond to a data frame rate (fr) of the digital transmission system (1) are extracted from the received voice signal and analyzed. In order to obtain a measurement value that is independent of signal strength, a standardization with the spectral output values occurring in the middle of the quoted frequencies can be conducted. For comparison purposes, an undistorted voice signal is processed the same way in advance. The measurement values of the transmitted voice signal are placed at a ratio to the reference values and then evaluated, e.g., by a neuronal network (13).

Abstract: A document feeder employs a lifting lever to lift stacked documents away from a feed roller each time a document is being fed away from the stack. In this way the separation of documents is enhanced, providing a mechanism that more readily accommodates documents of varying shapes, thicknesses, and materials. The feeder uses a motor linked by one-way clutches to feed mechanisms for documents and for labels, stacked separately. The motor is driven in one direction to feed documents and in the other direction to feed labels. A moistener is provided below the paper path, and the moistener is mounted so that it can be slidably removed. When it is removed, feed rollers are permitted to relax and move apart which helps in the clearing of jams.

Abstract: A method and apparatus for transmitting a signal through a power magnetic structure. A power magnetic core has one or more windings for transmitting power, and two windings for transmitting a signal or auxiliary power. The signal or auxiliary power windings are looped around features of the core so as to cancel the effect of magnetic flux circulating in the core as a result of currents flowing through the one or more power windings.

Abstract: A signal used in the transmission of data in a communication system (for example in an ATM network), comprised of immediately successive cells. For the purpose of cell synchronization, filler cells (I) containing a predefined bit pattern are provided. This pattern is provided with an error protection code that differs from the error protection code used for the user data. Even if the user data should coincidentally contain the predefined bit pattern, the synchronization circuit will not be able to be simulated, since this false bit pattern is provided with a different error protection code. In order to test and ensure the synchronization state, a BIP value at the end of the cell is checked at the receiver end.

Abstract: A postage meter (franking machine) uses a digital print head such as an ink-jet or thermal transfer or dot-matrix print head, for which it is necessary to know the velocity of the mail piece passing by the print head. Two collimated monochromatic beams strike the mail piece, one at an angle leading the mail piece velocity and the other at an angle lagging the mail piece velocity. The beams converge yielding a sensing region filled with a diffraction pattern. The mail piece, assumed to be rough at a scale that is appropriate for the velocity measurement, moves at some velocity. A detector detects light intensity (photon flux) at a small region within the sensing region, and the intensity signal has a frequency that is proportional to the mail piece velocity. The frequency is detected or measured, the instantaneous velocity is derived therefrom, and the velocity is used to control the print head.

Abstract: A transformer providing low output voltage. A transformer core has two outer leg portions and a center portion. A primary winding has a first portion looped around one of the legs so that a current passed through the first winding will produce a magnetic flux in that leg that circulates in either the right hand or left hand sense. A second portion of the input signal winding is looped around the other leg in the opposite sense. This provides for a magnetic flux circulating through the two outer leg portions in the same sense, and provides that the magnetic flux circulating through the center portion is zero. The secondary winding is preferably provided as a fractional loop around one of the outer legs.

Abstract: A method and device for checking a telecommunication system (4) with respect to an accurate routine detection of system-internal call data records (13, 14). Various communications connections are established and later terminated between two subscriber stations (2,3) via the telecommunication system (4) on the basis of predefined communication parameters; further call data records (10a,10b) are independently prepared and saved from these communications connections at both of these subscriber stations (2,3); and the system-internal call data records (101013) for said communications connections that are routinely created by the telecommunications system (4) itself, are compared to the further call data records (10a, 10b).

Abstract: A current sensing cell, using PCB trace-loops, with the loops either contained in a single layer—horizontal loops, or in two separate layers—vertical loops interconnected by vias into a single two-pole inductive component. The horizontal loop-sensor cell will be used sideways, next to a planar conductor carrying a current parallel to the sensor traces, so as to collect the magnetic field lines on the side of the planar conductor, where they come closer together. The vertical loop sensor cell will be used on top or bottom of a planar conductor carrying current parallel to the cell, so as to collect the magnetic field lines going across the conductor, or between two parallel conductors, carrying parallel current of opposite sense, so as to collect the magnetic field lines that run in between the two conductors, summing up the two fields.

Abstract: The invention relates to an apparatus for initial charging of the output capacitors of a three-phase three-point pulsed rectifier system. According to the invention, a thyristor is arranged in each phase between the input terminal and is connected in the current flow direction to the anode of the freewheeling diode, and an initial charging path is connected in parallel with this thyristor. The circuit for actuating the thyristor is activated after completion of the initial charging; the reference voltage is applied to the negative input of the comparator.

Abstract: A stepping motor with an electrical activation circuit for electrical control of its exciter windings, is made as a driving motor and also as a braking motor with an adjustable braking action. The predefinable braking action is achieved passively without any current feed into the exciter windings. For this purpose a stipulated impedance with an adjustable duty factor can be connected to each exciter winding. One such stepping motor that is controlled in its braking action is used in an arrangement in which a strip or filament material can be transported braked from a storage.

Abstract: A postal meter mail piece feeder comprising a hopper section, a singulating section and a mail piece turner. The hopper section comprises a bottom mail piece support deck for supporting mail pieces thereon, a rear wall having a mail piece drive for contacting and moving the mail pieces along the support deck, and a front stop for biasing the mail pieces towards the rear wall. The singulating section is downstream from the hopper section and comprises a retard drive and a sensor connected to the retard drive. The mail piece turner is downstream from the singulating section and comprises a turning surface for turning the mail pieces about 90° from the singulating section for entry into a postage applying section of a postage meter.

Abstract: A postage meter has a locking cam follower so that locking arms on the print wheels of the postage meter are able to lock the wheels from unintended movement when the print rotor is out of its home position. Stiff runners are provided below guide rods of setting racks in the rotor so that the racks cannot be displaced away from the value wheels. A sensor is placed on the rotor cover with the meter software set up to keep a print cycle from starting if the cover is open. A cam on the rotor makes it impossible to open the cover when the rotor is out of the home position. A latch holds the cover shut, and the only way the latch can be released is if the meter software releases it, for example by sliding a rack to a position that triggers the latch. Cogs and cog teeth are used instead of gears and gear teeth to reduce the possibility of unintended movement of the value wheels. Rotating disks lock the racks when the rotor is not in the home position.

Optionally a receiving area is provided which can receive a printed sheet, and a touch-sensitive area is juxtaposed with the sheet, permitting user selection of items on the printed sheet. By means of a scrolled display of subsets of a character set, the user may readily create text strings on the touch-sensitive display of limited size. A history is kept of frequently selected print parameters, and the user can scroll through a list derived from the history.
