Patent CA-2145659-C (CA)
Inventor: DAUGMAN JOHN G
IPC: G06V10/42
Filed: 1992-10-10
Granted: 2004-05-25
Abstract: Image analysis algorithms find the iris in a live video image (10) of a person's face, and encode its texture into an "iris code" (24). Iris texture is extracted from the image at multiple scales of analysis by a self-similar set of quadrature bandpass filters defined in a dimensionless polar coordinate system. The sign of the projection of many different parts of the iris onto these filters determines each bit in an iris code. Comparisons between codes are readily implemented by the Exclusive-OR (XOR) logical operation. Pattern recognition is achieved by combining signal processing methods with statistical decision theory, leading to a statistical test of independence based on a similarity metric (Hamming distance) (26) that is computed from the XOR of any two iris codes. This measure positively establishes, confirms, or disconfirms, the identity of any individual (28). It also generates an objective confidence level (30) associated with the identification decision.

Title: Method and devices for wavelength and power demodulation based on the use of a quantum well electroabsorption filtering detector
Inventor: COROY TRENTON G
IPC: H04B10/158
Filed: 1996-11-20
Granted: 2003-02-18
Abstract: Devices for measuring one or more properties of a light signal is disclosed. More particularly the invention relates to devices for wavelength and power demodulation based on the use of quantum well electroabsorption photodiodes. In one aspect the invention provides and power and wavelength demodulation system based on a quantum well electroabsorption (QWEA) filtering detector. The input optical signal passes through an optical beam splitter with part of the signal input into a filtering detector which is a multiple quantum well electroabsorption (MQW EA) photodiode having a tunable bandgap and the other part into a reference detector. The input light signal is impinged on the QW diode perpendicular to the plane of the quantum wells. The output of filtering detector is amplified by an amplifier and the output of the reference detector is input into another amplifier. The output from reference detector amplifier serves as a measurement of the power of the input optical signal. The outputs of the amplifiers are input into an analog divider circuit where the signals are ratioed. A ratiometric voltage signal, Vratio, is obtained by ratioing the filtered output of filtering detector and the unfiltered reference output to provide optical intensity self-referencing (immunity to input power fluctuations). This Vratio output signal is continuously compared with a reference voltage signal, Vref, and the difference of Vratio and Vref is input into a feedback control circuit. The output voltage Vout of the feedback control circuit is used to bias the QW EA photodiode so that in closed loop operation the QW EA photodiode is continuously wavelength tuned to maintain Vratio equal to Vref.

Title: Method and apparatus for an improved language recognition system
Inventor: ALSHAWI HIYAN
IPC: G10L15/18
Filed: 1997-02-24
Granted: 2001-05-01
Abstract: Methods and apparatus for a language model and language recognition systems are disclosed. The method utilizes a plurality of probabilistic finite state machines having the ability to recognize a pair of sequences, one sequence scanned leftwards, the other scanned rightwards. Each word in the lexicon of the language model is associated with one or more such machines which model the semantic relations between the word and other words. Machine transitions create phrases from a set of word string hypotheses, and incrementally calculate costs related to the probability that such phrases represent the language to be recognized. The cascading lexical head machines utilized in the methods and apparatus capture the structural associations implicit in the hierachical organization of a sentence, resulting in a language model and language recognition systems that combine the lexical sensitivity of N-gram models with the structural properties of dependency grammar.
