Title: System and method for the detection and removal of radio frequency noise artifact from biopotential signals
Inventor: SHAMBROOM JOHN R
IPC: A61B5/308
Filed: 2002-06-21
Granted: 2008-09-16
Abstract: A system and method of identifying and removing artifact from radio frequency noise from biopotentials identifies epochs contaminated with radio frequency noise. Contaminated epochs are then replaced with recent uncontaminated epochs stored in a buffer, depending on the current level of artifact and the availability of suitable data. Discontinuities arising at the beginning of the replaced epochs are smoothed by means of a windowing function.

Title: A method for preparing a homogenous cellulosic product from cellulosic waste materials
Inventor: ELEY MICHAEL H
IPC: A61L11/00
Filed: 2001-10-22
Granted: 2010-06-15
Abstract: A method for treating diverse pulp and paper materials, including such products contained in municipal solid waste and biohazardous wastes, to produce a homogenous cellulosic product comprises the steps of feeding diverse pulp and paper materials into a vessel, introducing steam into the vessel while agitating the materials, purging the gases from the vessel while agitating the materials, sealing the vessel so that the vessel is pressure tight, saturating the materials with steam at sufficient temperature and pressure to expand the physical and chemical structure of the materials, while agitating the materials, depressurizing the vessel to further enhance the physical and chemical expansion of the materials, and discharging the processed products. Alternatively, the method can be performed without purging the gases, if the temperature in the range of about 140 ~C to about 160 ~C, and the pressure is in the range of about 275 to 450 kPa. During the optional purging step, during the depressurization step, and during the optional evacuation step, volatile organic compounds and other air pollutants can be captured and treated. The temperature, pressure, and process time is more than sufficient to decontaminate and sterilize biohazardous laboratory and medical wastes.

Abstract: L'invention concerne un système et un procédé permettant de coder et de décoder des données vidéo. Dans un système et un procédé de compression de données vidéo, une trame vidéo (32) est divisée en séquences de blocs d'images (38), l'un des modes de codage de bloc possible étant un mode de compensation de mouvement global implicite (IGMC) utilisé pour copier des pixels provenant d'une trame antérieure (32) déplacée au moyen d'un vecteur de mouvement prédit. Dans un autre mode de réalisation de l'invention, une trame vidéo (32) de système et de procédé de compression de données vidéo est segmentée en séquences de tranches (36), chaque tranche (36) comprenant un certain nombre de macroblocs (38). Les tranches respectives (36) sont codées et un signal est inclus dans l'en-tête (44) d'une tranche codée (40) afin d'indiquer le moment où la tranche (40) est activée par compensation de mouvement global (GMC), c'est-à-dire le moment où GMC doit être utilisée pour reconstruire la tranche codée. Le cas échéant, des informations GMC, telles que des informations représentant un ensemble de vecteurs de mouvement (42a-42d) sont incluses dans la tranche codée. Dans un mode de réalisation utile, chaque tranche (36) de trame (32) contient les mêmes informations GMC afin d'améliorer la résilience contre les erreurs. Dans un autre mode de réalisation, différentes tranches (36) de trame (32) contiennent des informations GMC différentes. Dans les deux modes de réalisation, des vecteurs de mouvement (42a-42d) de chaque image d'une tranche codée (40) particulière peuvent être reconstruits au moyen des informations GMC contenues uniquement dans cette tranche codée particulière.

Abstract: The present invention provides an intrusion detecting system and method for precisely locating an intruder along the length of a sensor cable and for determining the intruder distance from the cable to precisely locate multiple, simultaneously occurring intrusions. The method includes the steps of: generating a TX signal and transmitting same over a first transmission line of the sensor cable, for creating an electromagnetic field; detecting an RX signal induced in a second transmission line of the cable by the electromagnetic field and identifying in the RX signal a contra-directional reflection received from a target and a co-directional reflection received from the far-end (F) of the first transmission line, processing the contra-directional reflection for providing a first coordinate (R) of the target, and processing the co-directional reflection for providing a second coordinate (Z) of the target. The method and system may also be implemented with a "true one cable" using a single coaxial cable sensor with a directional coupler for separating coupled signals along a single transmission line in the cable. Ultra high speed data correlation of the RX signal is achieved through use of a field programmable gate array. The present invention also provides a separate calibrated threshold for every meter of cable to reduce the installation cost associated with meticulous control and the number of cables required for sites with varying burial mediums. In another embodiment, the use of two parallel single cables may be utilized whereby each cable in the system is used to detect and locate intruders independently and more clearly define the direction of crossing and the speed of crossing.
