Patent CA-2378984-A1 (CA)
Inventor: WILKINSON GRANT R
IPC: A61K31/445
Filed: 2000-08-07
Abstract: L'invention concerne une composition pharmaceutique comprenant un 10, 11 méthanodibenzosubérane, et l'utilisation de cette composition pour le traitement de l'infection à VIH. L'administration conjointe de ce 10, 11 méthanodibenzosubérane et d'un inhibiteur de protéase VIH permet d'augmenter la concentration de l'inhibiteur de protéase dans certains tissus, notamment dans le cerveau et dans les testicules, sans augmenter de manière notable les concentrations plasmiques de l'inhibiteur de protéase. On peut ainsi mettre en oeuvre un traitement antiviral complémentaire sans augmentation des dosages des médicaments, ce qui permet de réduire le risque d'effets secondaires liés à la toxicité des médicaments.

Title: Compositions comprising modafinil for treatment of attention deficit hyperactivity disorder
Inventor: MILLER MATTHEW S
IPC: A61K9/20
Filed: 2000-08-16
Abstract: Modafinil is effective in improving symptoms of attention deficit hyperactivity disorder and symptoms of multiple sclerosis fatigue. The administration of modafinil is also shown to activate the tuberomamillary neurons of the posterior hypothala-mus, and thus exhibits activity in an area of the brain associated with normal wakefulness functions.
Patent CA-2380948-A1 (CA)
Inventor: DAVIS S CHRISTOPHER
IPC: H01J49/04
Filed: 2000-08-11
Abstract: This invention provides libraries of recombinant derivatizing enzymes that are useful for biocatalytic synthesis of derivatives oforganic molecules, including lead compounds for pharmaceutical use. The recombinant derivatizing enzymes catalyze reactions such as modification or replacement of functional groups on the organicmolecules, or addition of chemical moieties onto preexisting functional groups. The use of recombinant enzyme libraries enables one to obtain enzymes that catalyze the formation of organic molecule derivatives that could not otherwise be made using only naturally occurring enzymes.

Title: Low cost long distance rfid reading
Inventor: MONICO DOMINICK L
IPC: B65D5/42
Filed: 2000-09-28
Abstract: In the production radio frequency (RF) sensable objects, it is possible to produce a package, envelope (10), or like container which has enhanced read distance, producable by a simple method.  Large areas are printed on the envelope or package in conductive ink (12, 14) which are separated by a non-conductive portion (15) of the package or envelope and function as an RF antenna. Then by placing an otherwise conventional label (17) with an RFID  chip (19) associated with it so that it bridges the conductive ink portions of the RF antenna, a much easier to sense or read product is produced. The conductive ink can be applied in a pattern, logo, and letters or character indicia. The label may have conductive pressure sensitive adhesive on one face, which actually connects the antenna sections to the RFID chip to form the operable structure that can be sensed by an RF receiver at a distance of three meters or more.
Patent CA-2385040-A1 (CA)
Title: Variable-speed control system for transmission
Inventor: ONOGI KENKICHI
IPC: F16H61/662
Filed: 2002-05-06
Abstract: In a constant horse-power type continuously variable transmission, a pressing force supply path using for a rotation-speed control, is supplied to one of an input pulley or an output pulley, and an elastic force supply path using for an axial torque control, is supplied to the other. However, since the one pulley is applied only the pressing force as a control element although the torque of the other pulley can be regulated by the elastic force, the frictional force applied to said one pulley cannot be positively regulated, and consequently, whole axial torque controls of an input shaft and an output shaft cannot be achieved sufficiently, and the effect causes the transmission efficiency to deteriorate at both end ranges of a variable speed range. In the present invention, a variable-speed control system for a transmission makes axial torque controls of both the input and output pulleys compensate and hold a low-speed range and/or a high-speed range into a higher transmission efficiency, while cooperating with the semi-elastic force to the one pulley, of which elastic vibration is suppressed by the pressing force thereto to half, and the elastic force to the other pulley. Further, the variable-speed control system is capable of widely expanding an entire transmittable range width to maintain the state of higher transmission efficiency, in combination with a first speed-ratio range and a second speed-ratio range of a first and a second transmission device. By means of using at least the application of the semi-elastic force to the pulley or combination of two individual speed-ratio ranges, a band width of an entire transmittable speed range of the variable transmission is substantially enlarged.

Title: Variable length encoding of compressed data
Inventor: LE KHIEM
IPC: H03M7/30
Filed: 2000-11-02
Abstract: The invention is a method and system for compressing a current value into a minimum number of bits for transmission from a compressor to a decompressor. A method in accordance with the invention includes maintaining a series of at least one previous value at the compressor, each previous value having different k least significant bits and which have been transmitted to the decompressor; determining a value of k representing a smallest number of bits which allows successful decompression of the current value at the decompressor using as a reference value any value in the series of at least one previous value; and transmitting the current value from the compressor to the decompressor in compressed form with the k least significant bits of the current value.
Patent CA-2389463-A1 (CA)
Inventor: WEATHERS ARTHUR K
IPC: A61B17/16
Filed: 2002-06-06
Abstract: This application relates to a dental apparatus for the initial and subsequent guidance of hypodermic needles, or similar drug delivery devices into the cortical plate of human mandibular and maxillary bones. The invention comprises a solid drill bit bearing a channeling groove along the majority of the shaft. The groove is scalloped at its delivery end to flex the needle tip and deflect the tip out from the drill and into the desired tissue.      Variations are described, with the preferred embodiment having the circumference of the drill bit reduced in girth for the length bearing the groove. This permits an inexpensive plastic covering which serves as a practical seal against bacteria. The seal is permeable to the needle's tip and closes back on itself after withdrawal of the needle.

Title: Dynamic selection of field/frame-based mpeg video encoding
Inventor: KLIVINGTON JASON
IPC: H04N7/50
Filed: 2003-01-06
Abstract: A discrete cosine transform (DCT) level enhancement to Motion Picture Experts Group (MPEG) video encoding is described that results in a more concise bitstream than MPEG encoding without the enhancement. One degree of freedom provided by the MPEG encoding specifications is whether a frame- or field-based DCT operation will be used. In the field-based DCT operations, luminance sub-blocks are built from even or odd rows of the original image, which correspond to the top and bottom fields in field-based video. This allows the encoder to take advantage of the higher correlation between rows for the same field, especially in field-based video with a high level of motion. In one embodiment, both field-and frame-based DCT operations are performed and the results are quantized. On a macroblock-by-macroblock basis, the option that results in the fewest non-zero coefficients is selected and those coefficients ire used for run-time encoding.

Abstract: In writing a unitary image on an imaging media using two or more exposure heads where each exposure head writes a portion of the unitary image, alignment of the imaging heads is essential to ensure that an artefact is not apparent where the imaged portions join. The alignment is accomplished by determining the degree of misalignment between the heads by examining an image that has been written and then adjusting the scanning speed of at least one of the exposure heads to compensate for any misalignment.
