  • Patent number: 6169936
    Abstract: The invention concerns a method of controlling the input station in a letter-sorting installation, the input station having a scanning and reading device and a mechanical letter-storage path in which letters are conveyed after being scanned by the scanner, the position x at which the address of each letter is read along the storage path being controlled so that x remains between specified values x0 and xmax. The invention calls for the number y of uncoded letters along the storage path to be determined in an auxiliary control circuit and the value of y used to generate the control signal u for control of the input station by a control unit.

  • Patent number: 5915037
    Abstract: The invention concerns a method and device for binarization of pixel data in which a number of black-and-white binary images each having binarization characteristics of different degrees of sensitivity is formed from a set of grey scale value binary data. A dimension S is calculated for each of these binary images, according to the equation ##EQU1## where FS designates the number of black binary pixels and U designates the number of black-and-white transitions. A selection of the binary image for which the dimension S is at its maximum is optimally carried out.

  • Patent number: 5870715
    Abstract: A logistical network has nodes and edges, or transport links, which permit mailed articles that are being set from a sender to a receiver to be transferred, processed, and forwarded in a sequence which is predetermined in terms of time and place. The network includes devices for determining differences between nominal data describing the state of the logistical network and actual measured data. A controlled system is provided for minimizing differences in a predetermined period of time by shifting the processing of mailed articles from one node or a plurality of nodes of which the capacity is reduced with respect to the nominal data to one or a plurality of other nodes such that minimal additional expenditure is incurred.

  • Patent number: 5584649
    Abstract: A device for separating flat parcels from a stack of parcels includes a drawing element that travels in a conveying direction and acts by friction on a parcel to be drawn off from the stack of parcels. A guide wall for the stacked parcels forms a gap with the drawing element for a drawn off parcel to pass through. A support surface supports the stack of parcels and generates a stack pressure in a direction of the drawing element. At least one first nozzle disposed in the region of the support surface, and/or the region of the guide wall, blows compressed air between the parcels in the stack. At least one second nozzle, disposed in the region of the gap, between the stack of parcels and the guide wall, blows compressed air having a predetermined inclination counter to the conveying direction of the parcels to be drawn off.

  • Patent number: 5574462
    Abstract: A proximity detonator which derives its firing criterion from reflected beam measurements and thus obtains information about the radial relative velocity of the detonator with respect to its target object by evaluating the Doppler effect, wherein the firing signal is produced by a circuit including a function generator whose output voltage has a time sequence which corresponds to the decrease in radial relative velocity as the detonator approaches its target object (possibly under consideration of a correction value resulting from the firing law), a voltage controlled oscillator whose control input is connected to the output of the function generator, and a phase comparator having two signal inputs, one of which receives a Doppler signal which corresponds to the radial relative velocity and the other of which is connected to the output of the oscillator.
