Granted: 1999-09-07
Abstract: A temporally-pipelined predictive encoder/decoder circuit for encoding or decoding an input signal containing a sequence of data frames received at a particular frame rate and frame data rate into an output signal having an equal frame rate employs a plurality of N predictive encoders/decoders. An input buffer may be used to extract the information for each data frame in the input signal and supply such information to a corresponding one of the encoders/decoders at rate of 1/N of the particular frame data rate. Each encoder/decoder generates corresponding encoded/decoded information as it is received as well as provides digitized frame information to the encoder/decoder processing the next received image frame. The encoded/decoded information is provided to corresponding frame buffers which temporarily store such information. Each one of the frame buffers is connected to respective inputs of a multiplexer, wherein the encoded/decoded information is provided to a multiplexer output to form the encoded/decoded output signal. When information for the entire frame has been stored by a frame buffer,the stored data information is provided to the multiplexer output to provide theportion of the output signal corresponding to that frame.

Title: Sliding interleaved motsa for magnetic resonance imaging
Inventor: LIU KECHENG
IPC: A61B5/055
Filed: 1996-10-16
Granted: 2005-02-01
Abstract: A method for the elimination of slab boundary artifact (SBA) or venetian blind artifact in three dimensional multiple overlapped thin slab acquisition (3D     MOTSA) for magnetic resonance angiography (MRA). The method uses a sliding slab, interleaved K-space MOTSA (SI-MOTSA) data acquisition strategy, equalizing flow-related signal intensity weighting accross the entire slab dimension. The method demodulates signal intensity changes along the slab direction and can essentially eliminate the SBA while retaining the same or better imaging time efficiency as that of conventional MOTSA, providing robustness to complicated flow patter and thereby resulting in more accurate depiction of vascular morphology. In addition, the method does not need specialized reconstruction and extra computation.

Patent CA-2208418-C (CA)
Inventor: WOODRUFF BRYAN A
IPC: G06F17/30
Filed: 1997-06-19
Granted: 2008-05-20
Abstract: A method and computer program product for synchronizing processing between two or more data streams (e.g., video and sound input) and for rate matching between two different hardware clocks that may drift with respect to one another (e.g., an originating clock represented in a timestamped data stream versus a clock actually rendering the data) in a system of interconnected software drivers running in kernel mode. The present invention overcomes the coordination complexity and inaccuracies in the prior art by providing a clocking mechanism in a system wherein multiple drivers having input and output connection pin instances are chained together. The clocking mechanism synchronizes between data streams by providing a master clock on an input pin instance of a driver that is used to synchronize with other input pin instances on other drivers and "slave" clocks. Synchronization is achieved through event notification or stream position queries so that corresponding frames of data in separate streams are rendered together (e.g., video frames with corresponding sound track). Rate matching is achieved through monitoring a physical clock progression in comparison with a series of data stream timestamps thereby allowing adjustments to match the different clock rates. A common physical clock (e.g., PC clock) can be used as a reference for a component to translate a particular clock time to a time shared by all components with a minimum of error.

Title: Spring cartridge rotor bearing
Inventor: WATSON ARTHUR I
IPC: E21B4/00
Filed: 1997-07-16
Granted: 2004-10-12
Abstract: A spring cartridge rotor bearing is inserted into an electric motor during assembly as a preassembled unit. The rotor bearing includes a sleeve having a bore adapted to receive therethrough a shaft of the electric motor, and each end of the sleeve adapted to contact adjacent motor rotor sections. A bearing has a bore extending therethrough with the sleeve received therein. The bearing thermally locks into the stator bore early in motor warm-up and the bearing has sufficient end play on the sleeve to accommodate shaft expansion. One or more springs are located on the sleeve to bias the bearing to a neutral or generally centered position on the sleeve. The springs permit the bearing to move along the sleeve during times of thermal expansion and contraction, and prevent the bearing from becoming locked into an extreme position. This prevents the transmission of thrust loads from the rotor to the bearing.

Abstract: La présente invention concerne des compositions pharmaceutiques à base de  gamma -butyrobétaïne et de 3-(2,2,2-triméthylhydrazinium) propionate (ou "Mildronate"). Ces compositions conviennent en administration orale, parentérale, sous-cutanée ou rectale, au traitement des affections cardiovasculaires de diverses étiologies et localisations, des troubles de la circulation sanguine, de l'angine de poitrine, de l'infarctus du myocarde, de l'arythmie, de l'hypertension, de la myocardite et de l'insuffisance cardiaque. En expérimentation, cette composition administrée à raison de 5 mg/kg de  gamma -butyrobétaïne + 5 mg/kg de Mildronate à des chats anesthésiés, augmente in vivo le débit sanguin total de 18 %, sans changement notable de la tension artérielle et du rythme cardiaque. Cette composition bloque les spasmes induits par l'adrénaline au niveau des vaisseaux sanguins d'une oreille isolée de lapin, et lorsqu'elle est administrée dans une concentration de 2,0  mu M de  gamma -butyrobétaïne + 2,0  mu M de Mildronate, elle fait baisser la pression de reperfusion de 33 %. Le blocage de la NO-synthétase fait essentiellement baisser l'effet de la composition sur les spasmes induits par l'adrénaline au niveau des vaisseaux sanguins. Administrée à raison de 60 mg/kg de  gamma -butyrobétaïne + 40 mg/kg de Mildronate, la composition fait baisser de 70 % la mortalité de la souris par arythmie induite par le CaCl2. Administrée à raison de 30 mg/kg de  gamma -butyrobétaïne + 30 mg/kg de Mildronate, la composition fait baisser de 60 % la mortalité du rat par arythmie induite par CaCl2. Dans des posologies prophylactiques et thérapeutiques de 50 mg/kg de  gamma -butyrobétaïne + 50 mg/kg de Mildronate, la composition dans des expériences menées sur le rat empêche effectivement le myocarde de subir des défaillances, induites par l'occlusion consécutive à une reperfusion, et des fibrillations ventriculaires. Dans le cas d'expériences comparatives, la composition de l'invention fait preuve d'un effet plus puissant que la préparation connue de Mildronate associée à la  gamma -butyrobétaïne lorsqu'elles sont administrées séparément. La composition est remarquable pour sa faible toxicité et sa grande marge de sécurité d'action thérapeutique.
