Patent CA-2019165-C (CA)
Title: Method and apparatus for validating a paper-like piece
Inventor: YOSHIHARA KENZO
IPC: G07D7/20
Filed: 1990-06-18
Granted: 1996-02-13
Abstract: An apparatus and method for validating a paper-like piece  are of a type having a detector which  irradiates light  onto  a  deposited paper-like piece  and  thereby produces  a detection signal corresponding to a  pattern on  the paper-like piece and validating  the  paper-like piece  by collating the detection signal produced by the detector  in  response to deposition of  the  paper-like piece with a predetermined standard  pattern.   Features of  the apparatus and method are that a reference paper-like piece having no particular pattern is deposited and reference  level  data  is obtained on the  basis  of  a detection signal produced by the detector in response to this deposition, that data to be examined is provided by converting  a detection signal produced by the  detector in  response to deposition of a paper-like piece  to  be validated  to a ratio to or deviation from the reference level data and that validation is made by collating this data  to be examined with the standard  pattern.   Since the base for normalizing measured data for collation  is set  at  the  level of the reference  paper-like  piece, validation becomes less vulnerable to adverse effects by a parts error and an assembling error in an optical type detector  with resulting improvement in  the  validation accuracy.

Title: External-to-internal numbering plan aliasing
Inventor: BOGART FRANK JEFFREY
IPC: H04Q3/62
Filed: 1992-08-26
Granted: 1997-04-08
Abstract: External invocation of features on a switching system from a network is made possible by aliasing otherwise-unused network numbers that are assigned to the switching system within the network numbering plan to feature-access codes of the switching system's internal numbering plan, in the switching system's call processing arrangement that uses stored definitions of syntax and grammar of the internal and network numbering plans. The aliasing is accomplished as follows. The syntax definitions of the internal numbering plan include definitions of individual feature access codes, while the syntax definitions of the network numbering plan includedefinitions of the aliased network numbers, which either are the same as the definitions of the corresponding feature access codes or direct the aliased network numbers to be translated into the corresponding feature access codes. In use, symbol strings received by the switching systems are parsed to identify them as featureaccess codes or aliased network numbers, requisite translations are performed, and feature modules that are pointed to within the definitions are invoked.

Title: Method of recognizing handwritten symbols
Inventor: SINDEN FRANK WILLIAM
IPC: G07C9/00
Filed: 1993-03-15
Granted: 1996-10-01
Abstract: An unknown handwritten symbol written on a digitizing tablet is compared with symbols in a predefined "alphabet" or library of model symbols andthe closest match chosen. Recognition is independent of the size, position or orientation of the symbols. The alphabet can be any collection of symbols, such as alphanumeric characters, ideograms or words in cursive script and is created by writing at least one example of each symbol on the tablet.  A sequence of samples of the pen position is recorded while a symbol is being written.  The samples form a vector, which is then translated so that the centroid of the symbol lies at an origin. The comparison, which can easily be done in real time, involves calculating a correlation factor from scalar products of the vector for the unknown symbol andtwo versions of the vector for each model symbol and choosing the model symbol having the highest correlation factor.  If needed to distinguish between model symbols with similar correlation factors, the comparison can also include calculating a rotation factor from such vectors for use in making such choice. Embodiments of the invention can be configured that are user-independent, user-dependent or that evolve from one to the other.
