A novel match/mismatch emulation scheme for an addressed location in a CAM system that includes a plurality of CAM blocks. The plurality of CAM blocks are organized into at least one rectangular array having rows each having a plurality of CAM blocks, a group of CAM cells and associated read/write bit lines connecting the group of CAM cells to an addressed search circuit. During debug mode, where the individual array cells do not participate in search, all the cells in the debug column behave the same way to emulate a match/mismatch on all words. The circuit provides a control input to include address evaluation of a debug cell in a row. The circuit also provides simultaneous switching noise analysis on an evaluating row. The resulting CAM cell provides a circuit to test individual rows for defects and noise analysis.

The apparatus greatly reduces the registered data amount and the verification computation amount required for user verification, in comparison with the verification using image information itself, and also decreases the false verification rate. The apparatus divides a biometric information image into cells, and extracts minutia information as well as cell basic information from the individual cells. After comparison of direction information of the individual cells of the registered data with direction information of the individual cells of the to-be-verified data, thereby aligning the registered fingerprint image and the to-be-verified fingerprint image, the apparatus compares the minutia information of corresponding cells between the registered data and the to-be-verified data to make a match/non-match decision. Such an apparatus is applicable to systems that employ pattern matching type image verification to perform user verification utilizing biometric information such as fingerprints, palm prints, blood vessel patterns, iris patterns, and facial images.

The present invention discloses devices and methods for improving data correlation using a multiple-correlation state-machine, the method including the steps of: (a) pre-processing a data frame having a plurality of symbol sets, wherein each symbol set demarks a respective frame field of the frame, to provide a threshold-compared hamming-distance indicator; (b) comparing the threshold-compared hamming-distance indicator with at least one multiple-correlation threshold to provide a threshold-compared multiple-correlation indicator; and (c) combining the threshold-compared hamming-distance indicator and the threshold-compared multiple-correlation indicator to determine a match/no-match comparison indicative of the respective frame field. In some embodiments, the step of combining includes forming a logical-AND of the threshold-compared hamming-distance indicator and the threshold-compared multiple-correlation indicator. Preferably, the method further includes the step of: (d) prior to the step of combining, comparing a BER of the frame to a BER threshold. Also disclosed is a weighted-correlation method for improving data correlation.

Rectangular partial areas “Ri” for use in template matching in a process of determining match/mismatch between fingerprint images are spread adjacently to each other in one of the images. A boundary-including partial area is set in a portion including a crossing point of cross-shaped boundaries defined by the four neighboring partial areas. The plurality of partial areas formed of the neighboring partial areas and the boundary-including partial area are used as a template so that the number of the partial areas can be increased while ensuring a certain size of the partial area. Further, the boundary-including partial area covers the boundary between the neighboring partial areas so that continuity of image data at the boundary between the neighboring partial areas can be reflected in the determination of the match/mismatch between the images.

A system and method for statistical matching that determines statistical curves for data described in a data request and stored data that satisfies the request. The system may determine the statistical curves for each data type and determine whether any overlap exists between the statistical curves. A user may specify a particular acceptable percentage of data that may be used to satisfy the request. The data satisfying the request may be presented to the user or, alternatively, a match/no-match result may be presented indicating whether any data that satisfies the request exists.

A power supply controller with a function to identify whether or not a signal that was output is reliable and to perform the necessary processing on the input side when an unreliable signal was sent that might adversely affect the input side in communication systems. A controller 1 and a controlled device 21 are connected at both ends of a cable 17 (27) with connectors. The controller contains a first processing system 1, a second processing system 2, and a comparator 7. The first processing system and the second processing system 2 are for example equivalent to microcomputers, etc. The comparator 7 compares the outputs of these two processors and generates a match/mismatch signal according to whether the outputs are a match or not. When the two outputs are a match then the outputs of these processors are reliable. However if the outputs are a mismatch then it signifies there is an error in one of these processing systems. Either of these processors outputs a general output signal separate from the match/mismatch signal. The general output signal may be output from either the first processing system or the second processing system without passing through the comparator. The general output signal is converted to a contact signal. The match/mismatch signal functions to turn the monitor signal on the monitor signal line on and off. The actual connection for this (output signal line) is shown in the drawings. The monitor signal line forms a loop on the monitor signal line for the signal to move back and forth between the controller and the controlled device. The controlled device contains an internal open-identifier for sensing whether the control signal line is open or closed.

A CAM array including volatile or non-volatile ternary CAM cells that discharge their associated match line through a special discharge line (e.g., a low match line), instead of through the bit line, is disclosed. Each ternary CAM cell includes a pair of storage elements that are used to store a data bit value, a comparison element that is used to compare the stored value with an applied data value, and a discharge element that is coupled between the discharge line and the match line. During operation, when the applied data value matches the stored value, the discharge element de-couples the discharge line from the match line (i.e., a high voltage on the match line remains high). Conversely, when the applied data value does not match the stored value, the discharge elements couple the discharge line to the match line, thereby discharging the match line to the discharge line. By discharging the match line to the discharge line instead of the bit lines of the CAM array, the size of the CAM array is not limited by the length bit lines. Because the voltage on the match line is sensed to determine the match/no-match condition of a CAM cell, the match line does not need to be completely discharged.
