Title: A method and apparatus for symbol recognition using multidimensional preprocessing and symbol sorting
Inventor: LECUN YANN A
IPC: G06V30/10
Filed: 1993-09-09
Abstract: Data samples describing a plurality of micro-segments that compose a symbol to be recognized are received from a device such as an electronic pad. A preprocessor maps the micro-segments into cells of an array that has several feature dimensions. The preprocessor assigns values to the cells based on the length of a micro-segment associated with the cell, and how well the features of the associated micro-segment correspond to the feature label of the cell. The cell values are used as inputs to at least one of a plurality of neural networks, where each neural network is trained to identify symbols from a different group of symbols. A sorter examines the symbol to determine which neural network should be used to recognize the symbol. An output produced by the sorter controls a switching means that communicates the cell values to the proper neural network. The systemovercomes problems of previous systems, namely undue complexity and unacceptable error rates.

Abstract: In a method of positioning a work piece carrier member with regard to a machining apparatus, it is provided to insert the work piece carrier member into the machining apparatus and to fix it there in a position which at least approximately corresponds to a desired nominal position. Thereafter, the effective position of the work piece carrier member is determined by scanning two reference marks provided on the work piece carrier member. The determination of the exact position of the work pieces received in the work piece carrier member is carried out in a separate measuring and aligning station. The positional data thus determined are transferred to the machining apparatus. The effective position of the work pieces received in the work piece carrier member can be calculated on the basis of the position of the reference marks.      The invention further provides a work piece carrier member comprising at least two reference marks located in a certain horizontal distance from each other. Thereby, the exact effective position of the work piece carrier member in X- and Y-direction as well as regarding its angular orientation around the Z-axis can be easily determined.

Abstract: ABSTRACT     Cash vault (1) has vault control unit (7) to be operated alternately by two tellers (4a, 4b), with only a single banknote disbursement (11) and input unit (39). The disbursement opening of banknote disbursement unit (11) can be closed by a two-part cover (13a, 13b).  Only that opening part which is adjacent to the pertinent teller (4a, 4b) is cleared at the time for currency disbursement.    In this way, allocation of the amount of money made available to one of the two bank employees takes place without problems.  The second bank employee cannot take the banknote bundle made available to the first bank employee even inadvertently.    Preferably, vault control unit (7) can be removed from vault base unit (15) of cash vault (1) which contains a banknote repository.  The upper side of vault base unit (15) adjacent to vault control unit (7) is completely closed except for a narrow slot through which the banknotes can be disbursed from the banknote repository or input into the latter.  That is, with vault control unit (7) removed, there is sufficient protection against unauthorized access to the banknote repository.    For path selection of banknotes from banknote input unit (39) to the banknote repository or to banknote disbursement unit (11) or from the banknote repository to the banknote disbursement unit (11), a bar-shaped path selection element which can turn around its longitudinal axis is used.  The path selection element is traversed by at least one longitudinal slot.     Abstract  (Cont'd.) An input opening of input unit (39) for banknotes can be closed with hinged lid (57).  On the lid is a lever of a two-arm lever arrangement.  With the lever arrangement a banknote pressure plate for pressing the banknotes for their isolation can be pressed against a feed plate.  During the pressing process, the banknote pressure plate can move parallel to the surface of the feed plate due to the lever arrangement by closing the lid.
