Title: Systems & methods with identity verification by streamlined comparison & interpretation of fingerprints and the like
Inventor: HARKLESS CURT R
IPC: G06K9/00
Filed: 1998-04-10
Abstract: Preferably a sensor receives a print image from an authorized person to form a template, and from a candidate to form test data.  Power spectral density (PSD) data for the template and candidate are compared, to read out rotation & dilation; these are used to adjust the template or candidate preparatory to a correlation to find translation.  After applying the translation, and refinement of the rotation and dilation, normalized spatial correlation values (NSCVs) are used as a measure of quality of the match - and thresholded to make an early rejection or acceptance decision in very clear cases. Where the question is closer, isomorphic adjustment is applied to the entire template or candidate for a fairer comparison in their overlap area. Such comparison proceeds by the same type of PSD analysis - but for multiple subregions in the overlap area. Resulting NSCVs are averaged to obtain a measure of quality of the match, which again is thresholded for a final decision in the closer cases. Noise variance from the test data, vs. position in the image, is used to weight the importance of comparison with the template in each subregion. Nonvolatile memory holds instructions for automatic operation.
Patent CA-2265655-A1 (CA)
Inventor: FARREN CARL A
IPC: G01N35/02
Filed: 1997-11-12
Abstract: The invention provides an automatic analyzing machine comprising a unique reaction cup combination for running high volume chemical analyses, such as analyses for sodium, potassium, glucose, creatinine and BUN (blood urea nitrogen). The reaction cup combination includes an aluminum body having at least one flat smooth side. A planar heating element is sandwiched between the flat side and a planar outer sidewall. Within the planar outer sidewall is disposed a reagent inlet conduit coiled or otherwise disposed in planar fashion. By this design, heating of inlet reagent is more efficient and control of the temperature within the reaction cup is more precise. In a preferred embodiment, the reaction cup assembly includes a pair of such heating element and inlet conduit combinations so that the reaction cup can be rinsed with heated water instead of heated reagent. Such a design not only reduces the use of expensive reagent, but minimizes toxic waste disposal needs.

Abstract: A correlation detector is provided which can establish initial acquisition quickly, and achieve high accuracy tracking by extracting crosscorrelation components in a receiver for CDMA communication, and a communication system using the correlation detector is also provided. During the initial acquisition, a received signal 21 is supplied to a matched filter 43. When an acquisition decision circuit 45 decides that the matched filter 43 detects the acquisition, it controls a switching circuit 42 to supply the received signal 21 to multipliers 47 and 48, and resets a VCCG 29 and a spreading code replica generator 30. After establishing the acquisition, a received spreading code is quasicoherent detected, and the detected spread signal is multiplied by a phase advanced replica and a phase retarded replica.      Correlation detection signals are produced from the products, and squared components of the correlation detected signals are generated, summed in the opposite phase, and averaged along the time axis. The averaged signal is inversely modulated by a decision signal of received data to obtain a phase error signal, the decision signal being obtained by multiplying the received spread signal by a replica in synchronism with the received spread sinal, and by integrating the product over a plurality of chips to compensate for a receive phase error.      The replica generator is driven by a clock signal whose phase is controlled by the phase error signal.

Abstract: A hanger primarily designed to hold pants, skirts, ties or scarves, embodies one or more vertical arms attached to a horizontal bar.      Each vertical arm houses a solid or hollow retaining cylinder or ring, which rolls up and down between the walls of the vertical arm. One wall of the vertical arm has a channel. As a clothing article is inserted upward between the walls of the vertical arm, the article pushes the retaining cylinder up, causing it to roll along the channel and out of the way of the clothing article. When the article is released, it allows the retaining cylinder to roll back down and grip the clothing article between the surface of the retaining cylinder and the flat (non-channelled) wall of the vertical arm.
