A method of detecting fraudulent or erroneous data from a transaction data set is provided. A first transaction record having a plurality of key values is selected from a transaction record database. One of the key values is selected from the selected transaction record. The transaction record database is then queried for transaction records having the selected key value. A second database is compiled of transaction records that contain the selected key value. At least one other key value is then selected from the originally selected transaction record, and the transaction record database is again queried for transaction records also having the second key value. The results of the fist, second and any subsequent queries are added to a second or a suspect transaction database. Then, using the uncovered records, the transaction database is queried for the use of key values common to the uncovered set of transactions to see if additional records are suspect. A list of queried key values is maintained to prevent the unnecessary or redundant use of the same query of the transactions. Risk coefficients of levels of fraud or mistake are assigned to the transaction records which have one or more common key values to the records uncovered as a consequence of the database queries.

A structure and method for testing spacing of wiring in a circuit comprises forming a plurality of conductor rectangles representative of conductors of the circuit, forming minimum spacing rectangles around the conductor rectangles (the minimum spacing rectangles being larger than respective ones of the conductor rectangles), identifying a possible error rectangle when a first conductor rectangle of the conductor rectangles occupies a portion of a minimum spacing rectangle of a second conductor rectangle of the conductor rectangles, checking whether the possible error rectangle is a true error, and reporting the true errors.

Reproduction signals include patterns for which recognition errors are likely. With respect to such patterns, probable error patterns are prepared. Tables showing correct patterns and error patterns are prepared, and evaluation values accurately representing signal quality are calculated. In an apparatus using a PRML method, discrimination data and a plurality of predetermined bit sequence pairs are examined to detect matching. A bit sequence and corresponding two ideal responses are calculated. Euclidean distances between the two ideal responses and equalization signals are obtained, and the difference between the Euclidean distances is further obtained. A quality evaluation value of a reproduction signal is calculated based on a mean value, a standard deviation, an appearance probability of the predetermined bit sequence, and a Hamming distance between the predetermined bit sequence pairs.

A method of operation of a navigation system with predictive multi-routing includes: calculating a primary route; predicting a probable deviation location on the primary route; calculating a non-primary route for the probable deviation location; and sending the primary route, the non-primary route, or a combination thereof for displaying on a device.

A detector circuit is to be used for measuring current by means of substantially identically wound ring core transformers, in which magnetomotive forces are induced by a main current. The magnetomotive forces are counteracted by magnetomotive forces induced by a compensating current. Two of the ring core transformers (2, 3) are magnetized in antiphase by means of a modulation signal. The detector circuit includes optionally a synchronous rectifier for providing an adjusting signal for the compensating current. According to the invention means are provided for compensating for possible differences between the two ring core transformers for the modulation signal. These means include a cornmon winding surrounding the two ring cores (2, 3), said common winding detecting a possible error signal used in a negative feedback loop which automatically seeks to establish an equilibrium.

The present invention relates to a digital hearing aid, which models the structures of external ear canals, sizes and shape characteristics of which differ between respective persons, obtains resonance gains generated due to the structural characteristics of the external ear canals, and performs digitization and signal processing to allow the resonance gains to be used as the gain factors of the digital hearing aid, and thus applies the gain factors to digital signal processing units. Further, the present invention proposes a gain obtainment unit capable of taking both resonance gains, generated due to the structural characteristics, and gains, obtained through a hearing test, into account, thus reducing the time required for gain fitting and possible errors, and optimizing the performance of the digital hearing aid for each individual.

A search sphere-based linear block decoder is provided. A received vector, v, is decoded by computing a syndrome vector, S, corresponding to the received vector, v; (S=vH); obtaining a set of all possible error vectors, e, corresponding to the computed syndrome vector, S, wherein the set of all possible error vectors, e, is obtained from a pre-computed error table and has a specified maximum number of bit errors; calculating a set of all possible received vectors, x, based on the received vector, v, and the set of all possible error vectors, e; determining a k-bit code-vector x that is closest to the received vector, v; and determining an n-bit data-vector, d, associated with the k-bit code-vector x. The pre-computed error table can be generated by multiplying all possible error vectors by a Syndrome Matrix, to obtain all possible syndrome vectors associated with all possible error vectors.
