Title: System and method for merging tomographic images with human vision
Inventor: STETTEN GEORGE DEWITT
IPC: A61B8/00
Filed: 2001-07-09
Abstract: A device for combining tomographic images with human vision using a half-silvered mirror to merge the visual outer surface of an object (or a robotic mock effector) with a simultaneous reflection of a tomographic image from the interior of the object. The device maybe used with various types of image modalities including ultrasound, CT, and MRI. The image capture device and the display may or may not be fixed to the semi-transparent mirror. If not fixed, the imaging device may provide a compensation device that adjusts the reflection of the displayed ultrasound on the half-silvered mirror to account for any change in the image capture device orientation or location.

Abstract: Il existe plusieurs types différents d'arythmies cardiaques graves. La présente invention utilise les mesures d'intervalles RR (intervalles entre les battements) pour détecter la fibrillation auriculaire d'un patient, entre autres. La fibrillation auriculaire est un dysfonctionnement grave impliquant un battement du coeur généralement rapide et irrégulier. On utilise des histogrammes de densité de probabilité de .DELTA.RR (différence entre deux intervalles RR successifs) réalisés pendant la fibrillation auriculaire d'une pluralité de sujets comme référence pour la détection d'une fibrillation auriculaire. Dans un mode de réalisation, on compte 16 histogrammes standard .DELTA.RR de densité de probabilité à chaque 50 ms d'un intervalle RR moyen d'un nombre donné de battements, l'intervalle RR moyen étant compris entre 350 ms et 1149 ms. On détermine la similarité entre les histogrammes standard de densité de probabilité et un histogramme test de densité de probabilité de .DELTA.RR d'un patient au moyen d'un test de Kolmogorov-Smirnov. Si l'histogramme de densité de test n'est pas sensiblement différent de l'histogramme de densité standard, une fibrillation auriculaire est détectée.

Abstract: In communications, there exist various communication ways with different control (WWW, WAP, email, SMS...). Messages are written, sent and received using different user interfaces. With present communication ways it is difficult to connect them mutually and to redirect one communication. way into another. Also simple person to person communication tool is missing.        The new solution, suggested in the patent, is to use the bar on the display as a form for unified messaging. The content of this bar communication is created by connecting various communication ways, redirecting one communication way into another communication way and direct bar to bar communication.        This solution puts together simple and user friendly communication environment with powerful content of unified messaging.

Filed: 2002-07-11
Abstract: A method, system, and computer program for improving the image quality of one or more bi-directionally predicted intermediate frames in a video image compression system, where each frame comprises a plurality of pixels (See fig.  4). In one aspect, the invention includes determining the value of each pixel of each bi-directional predicted intermediate frame as a weighted proportion of corresponding pixels values in non-bidirectionally predicted frames bracketing the sequence of bi-directionally predicted intermediate frames (See fig. 4, item 400). In one embodiment, the weighted proportion is a function of the distance between the bracketing non-bidirecitonally predicted frames (See fig. 4, item 401). In another embodiment, the weighted proportion is a blended function of the distance between the bracketing non-bidirectionally predicted frames and an equal average of the bracketing non-bidirectionally predicted frames (See fig. 4, item 403). In another aspect of the invention, interpolation of pixel values is performed on representations in a linear space (See fig. 4, item 405), or in other optimized non-linear spaces differing from an original non-linear representation (See fig. 4, item 406).

Abstract: New sensors and methods for qualitative and quantitative analysis of multiple gaseous substances simultaneously with both high selectivity and high sensitivity are provided. The new sensors rely on a characteristic difference in energy between the interaction of a particular substance with a catalyst coated heat transfer device (HTD) (5) (figure 1A) and a non-catalyst coated (or one coated with a different catalyst) reference HTD (10) (figure 1B).  Molecular detection is achieved by an exothermic or endothermic chemical or physical reaction between the catalytic surface of the sensor and the molecule, tending to induce a temperature change of the sensor. Both high temperature and non-destructive low temperature detection are possible. The magnitude and rate of endothermic or exothermic heat transfer from a specific molecule-catalyst interaction is related to molecular concentration.

Filed: 2003-12-31
Abstract: A mail processor and a method for processing mail is provided. The mail processor severs envelopes along one or more edges and transports the envelopes to a work desk where an operator removes contents from the envelopes. A feeder draws envelopes from the bottom of a stack of mail placed in a hopper. The envelopes are serially fed by tree feeder to a cutting assembly that severs each envelope along one or more edges. A transport assembly tilts each envelope in an inclined plane and presents the tilted envelope to an operator. An extractor opens the severed faces of the envelope to expose the contents to the operator and permit the operator to remove the contents from the envelope. In one embodiment of the invention, the envelope is discharged from the extractor to a verifier that confirms that the envelope is empty prior to disposal of the envelope.
