Title: Word grouping accuracy value generation
Inventor: JAMALI HAMADI
IPC: G06F40/00
Filed: 1999-03-08
Abstract: The present invention is a computer-implemented method for calculating word accuracy. Word grouping accuracy values (260) are calculated (212) by using the character accuracy values (250) calculated by an OCR program present in a computer system. The present invention preferably uses these character accuracy values (250) to create a word grouping accuracy value (260). Various methods are employed to calculate the word accuracy (260), including binarizing the character accuracy values (250). modified averaging of the character accuracy values (250), and creating fuzzy visual displays of word grouping accuracy values (260). The calculated word grouping accuracy values (260) are then adjusted based upon known OCR strengths and weaknesses. and based upon comparisons to stored word lists and the application of language rules. In a system with multiple character recognition techniques. the system can compare the accuracy values (260) of different versions of the word groupings to find the most accurate version. Then, the most accurate version of the word groupings is kept.

Abstract: A continuously adjustable surface mounting system for supporting objects in a range of positions with respect to a mounted surface. The system includes a surface mounted assembly and one or more support assemblies releasably secured at any point along a length of the surface mounted assembly. J-shaped bends formed in member(s) of the support assembly fit within T-shaped channels in the surface mounted assembly and react to cantilever force exerted upon the surface mounted assembly by binding within the T-shaped channels, thereby locking in place on the surface mounted assembly. Clips may be secured to the support assembly and tightened to prevent release of the support assembly from a force opposing the cantilevered force. A cantilevered member extending from the support assembly preferably supports a shelf on which objects may be placed. To adjust sag of the cantilevered member, tilt adjustment screws may be used to tilt the cantilevered member with respect to the remainder of the support assembly. Flexible wire management shrouds may flank and be attached to the surface mounted assembly for running and hiding wires, cords, etc. along the length of the surface mounted assembly. The flexible wire management shrouds provide easy opening and access to wires, cords, etc. within the wire management shrouds. Vibration isolation elements may be installed between the shelf and the remainder of the support assembly to isolate each shelf from receiving and transmitting vibration. A lighting system is preferably installed in several locations on the surface mounting system.

Abstract: Cette invention concerne un procédé et un dispositif (100) de traitement de signaux codeurs issus de turbomachines (10) en vue de la production de signaux en modulation de fréquence représentant des résonances parfaitement isolées des vibrations d'un rotor. Un traitement à capteurs multiples et à groupes de bandes latérales multiples (72) permet d'obtenir des résultats améliorés. On supprime les effets engendrés par la modulation de l'amplitude et les bruits aléatoires (56) au moyen d'une variété de procédés exempts de tout artefact. On sépare ainsi complètement les signaux en composantes (74, 76, 78) associées à la vibration de rotation et à la vibration de translation. La vibration de rotation entièrement isolante démasque des composantes du signal précédemment indécelables qui possèdent une valeur diagnostique. En cas de forte vibration d'arrière-plan, le filtrage de Wiener supprime les effets de la vibration exogène. Au moyen de ces divers procédés, la présente invention permet d'obtenir des informations diagnostiques considérablement améliorées permettant d'évaluer l'état et l'efficience des turbomachines.
Patent CA-2279471-A1 (CA)
Title: Detectors for cdma systems
Inventor: MAILAENDER LAURENCE EUGENE
IPC: H04B1/7093
Filed: 1999-07-30
Abstract: Linear space-time multiuser detectors are described that combine array processing, rake detection, and multiuser detection and that satisfy a minimum mean-squared error criteria. Both embodiments can be implemented adaptively so as to account for unknown sources of interference. The adaptive implementation of the first embodiment of a linear space-time detector requires explicit estimates of the channel coefficients. On the other hand, the adaptive implementation of the second embodiment does not require these estimates since they can be adaptively obtained. Both of these detectors provide significant performance advantages over single-user space-time detectors and over multiuser detectors which do not account for CDMA interference from unknown sources.

IPC: G16H20/70
Filed: 1998-04-14
Abstract: A method for diagnosing a psychiatric disorder in a subject, the method comprising the steps of: measuring the pattern of a subject's biophysical parameter and using said pattern to diagnose the psychiatric disorder. It has been found that certain clinical states are consistently associated with distincly different patterns of biophysical parameters. Normal and abnormal profiles are established, and subjects are tested by monitoring the pattern of a given parameter and comparing said pattern with reference patterns indicative of a psychiatric disorder. Heart rate is one biophysical parameter that can be readily and conveniently measured. Psychiatric disorders may be identified and diagnosed from analysis of characteristic patterns within portions of the circadian heart rate pattern. In one particular form, the heart rate pattern is measured over a period of at least approximately 90 minutes. The portion of the circadian heart rate pattern is preferably the sleep portion and in particular the sleep portion including the transition of the subject into and out of sleep. Preferably, the subject's heart rate is measured with a monitor that is unobtrusive and leaves the person freely ambulant.  Heart rate patterns may be affected by a range of factors. Some factors may produce noise that may hamper the interpretation of the heart rate pattern. Comparison of the subject's heart rate pattern with the record of the subject's activities allows for the effects of noise in the subject's heart rate pattern to be negated.

Patent CA-2287869-A1 (CA)
Inventor: JOINES WILLIAM T
IPC: H05B6/74
Filed: 1998-04-28
Abstract: The present invention overcomes many of the problems associated with electromagnetic exposure of planar materials (40). A diagonal slot (36) compensates for the effects of signal attenuation along the propagation path. Adjustably variable path lengths allow peaks (17) and valleys (18) of the electromagnetic field (16) in one exposure segment (30) to compensate for peaks and valleys in another exposure segment.   Dielectric slabs may be used to extend the peak field region between top and bottom conducting surfaces (12, 14) to allow for more uniform exposure of planar materials (40) that have a significant thickness (41). Specialized choke flanges prevent the escape of electromagnetic energy. One or more~ rollers between exposure segments (30) may be enclosed by an outer surface to prevent the escape of electromagnetic energy.
