Title: Position sensing and detection of skin impedance
Inventor: LEVIN MICHAEL
IPC: A61M25/095
Filed: 2006-08-25
Abstract: Apparatus and methods are provided for determining in near realtime the position of a probe placed within a living body. Electric currents are driven between one or more electrodes on the probe and electrodes placed on the body surface. The impedance between the probe and each of the body surface electrodes is measured, and three-dimensional position coordinates of the probe are determined based on the impedance measurements. Dynamic compensation is provided for changing impedance of the body surface and its interface with the electrodes, resulting from such causes as electrode peel-off and changes in moisture and temperature. The compensation improves the accuracy of, inter alia, medical procedures, such as mapping the heart or performing ablation to treat cardiac arrhythmias.

Patent CA-2562907-A1 (CA)
Title: Natural gas liquefaction
Inventor: WILKINSON JOHN D
IPC: F25J3/02
Filed: 2005-04-28
Abstract: A process for liquefying natural gas in conjunction with producing a liquid stream containing predominantly hydrocarbons heavier than methane is disclosed. In the process, the natural gas stream to be liquefied is partially cooled and divided into first and second streams. The first stream is further cooled to condense substantially all of it, expanded to an intermediate pressure, and then supplied to a distillation column at a first mid-column feed position. The second stream is also expanded to intermediate pressure and is then supplied to the column at a second lower mid-column feed position. A  distillation stream is withdrawn from the column below the feed point of the second stream and is cooled to condense at least a part of it, forming a reflux stream. At least a portion of the reflux stream is directed to the distillation column as its top feed. The bottom product from this distillation column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas.  The residual gas stream from the distillation column is compressed to a higher intermediate pressure, cooled under pressure to condense it, and then expanded to low pressure to form the liquefied natural gas stream.

Filed: 2005-04-22
Abstract: A system and method for minimizing timeouts when enhanced services are requested through a digital home communications terminal (DHCT) requiring discovery of a service group identification (SGID) assigned to the DHCT. A  service group map (SGM) includes a plurality of entries. Each entry includes a frequency, a tabulated transport stream identification (TSID), and a SGID  associated with one another. The SGM has multiple occurrences of the same frequency. The entries are arranged relative to one another such that first occurrences of each SGID are interspersed alternately with one another. A  match for the tabulated TSID can be found in order to determine the SGID  assigned to the DHCT before tuning any frequencies that correspond to second occurrences of any of the SGIDs. The frequencies associated with particular occurrences of each SGID may be prioritized.
Patent CA-2567611-A1 (CA)
Inventor: ASHDOWN IAN
IPC: H01S3/10
Filed: 2005-05-26
Abstract: The present invention provides a luminance enhancement apparatus and method for use with light-emitting elements comprising a conversion system adjacent the light-emitting element for converting electromagnetic radiation of one or more wavelengths to alternate wavelengths. This conversion process can be enabled by the absorption of the one or more wavelengths by the conversion system and emission of the alternate wavelengths thereby. The conversion system comprises a predetermined surface relief pattern on the face opposite the light-emitting element to provide a means for reducing absorption of the emitted alternate wavelengths in addition to providing a means for reflection of the emitted alternate wavelengths from the conversion system with a reduced number of reflections, thereby enhancing the illumination provided by the light-emitting element. As the present invention operates on principles of increased surface area and self-excitation of the conversion materials through the use of a predetermined surface relief pattern, the present invention may be applied to both organic LEDs, phosphor-coated semiconductor LEDs, and light-emitting elements coated with a population of quantum dots embedded in a host matrix.
Patent CA-2568049-A1 (CA)
Title: Pipeline architecture for analyzing multiple video streams
Inventor: RUSSELL STEPHEN G
IPC: G06T5/20
Filed: 2005-03-15
Abstract: A pipeline architecture for analyzing multiple streams of video is embodied, in part, in a layer of application program interfaces (APIs) to each stage of processing. Buffer queuing is used between some stages, which helps moderate the load on the CPU(s). Through the layer of APIs, innumerable video analysis applications can access and analyze video data flowing through the pipeline, and can annotate portions of the video data (e.g., frames and groups of frames), based on the analyses performed, with information that describes the frame or group. These annotated frames and groups flow through the pipeline to subsequent stages of processing, at which increasingly complex analyses can be performed. At each stage, portions of the video data that are of little or no interest are removed from the video data. Ultimately, "events" are constructed and stored in a database, from which cross-event and historical analyses may be performed and associations with, and among, events may be made.

Abstract: It is found out that age-related diseases or symptoms are induced in a knockout mouse lacking the function of S1-5 gene. It is also clarified by histological analysis that the bone mineral content, the bone density and the bone strength are lowered in this knockout mouse while the osteoclast count is increased in its bone tissue. By analyzing the osteoclastogenesis ability in vitro using bone marrow-origin cells of the knockout mouse, it is also clarified that this mouse has accelerated osteoclastogenesis ability and large-sized osteoclasts compared with a wild type mouse. It is disclosed that the addition of purified S1-5 protein to this in vitro system lowers the osteoclastogenesis ability.
