Abstract: A method is described for checking a value document, wherein measuring values of the value document are detected in spatially resolved fashion. The measuring value detected in the respective measuring point is allocated to a node corresponding to this measuring point, and a two-dimensional network of nodes is formed therefrom. A network is formed from the two-dimensional network of the nodes and a source node and a sink node. By means of the maximally possible flow through the network, the value document is classified as suspected of forgery or not suspected of forgery. The maximally possible flow through the network is a measure for the degree of probability of the value document having a continuous object along a direction transverse to the direction of the network, said object indicating a manipulation of the value document, such as e.g. an adhesive strip or a separating line of a composed forgery.

Abstract: Measuring the limpness of a note is necessary to separate a worn note out of circulation. Several methods are disclosed which can be used either alone or in combination to test for limpness. One method measures the note's ability to reflect light or transmit the light. Another method measures the response of the note to an acoustic wave. Another method measures the note's deflection to a pressure or force. Yet another method measures the dielectric value of the note when placed between the plates of a capacitor. A final method involves measuring the thermal conductivity of the note. In each case, a limp note will produce distinguishable results from a stiff note.

Abstract: A magnetic detection device for use in a bank note discriminating apparatus is proposed. A magnetic pattern which has been already formed on each bank note by applying the magnetizable printing ink thereon is detected by a magnetic detecting head of the device. The device further includes a conveyer driven at a conveying speed of V.sub.1, and a positioning roller rotated at a circumferential speed of V.sub.2. According to this invention, the speed V.sub.2 is adjusted to be approximately equal to or only slightly higher than the speed V.sub.1. According to another feature of this invention, the detection face of the magnetic head is spaced from the opposing peripheral face of the positioning roller by a gap D which is greater than the thickness T of the bank notes to be handled. By the use of the device of this invention constructed and operated as aforementioned, the magnetic detecting head is prevented from picking up noise signals caused by impulsive force applied thereon by the impinging leading end of the inserted bank note or uneven compression force otherwise applied thereon by the bank note which is bent on or above the magnetic head when the speed V.sub.2 is appreciably different from the speed V.sub.1 to accelerate or decelerate the travelling speed of the bank note just above the magnetic head.

Abstract: A method for evaluating sensor data for a value document includes a memory and a multi-core processor arranged to access the memory. A management sub-group of the cores comprises at least one of the cores, and at least one evaluation subgroup of the cores comprises at least one other of the cores. The management subgroup manages the memory regarding the storing of at least the sensor data and generates evaluation information for carrying out the evaluation. At least one evaluation subgroup carries out at least one part of the evaluation in dependence on the evaluation information and stores the result in the memory.
