Patent CA-2240776-C (CA)
Inventor: DAHL RUSSELL A
IPC: A61B19/00
Filed: 1998-07-16
Granted: 2006-01-10
Abstract: An assembly adapted to emit electromagnetic radiation made up of an emitter of electromagnetic radiation; a non-reflective ceramic support for the emitter; a substantially transparent crown mounted on the support to define and enclose a space that houses the emitter; and leads attached to the emitter through the support. The combination of the non-reflective support and the transparent crown, and the location of the emitter in the enclosed space enables the emitter to emit electromagnetic radiation in a conical radiation pattern. The radiation pattern appears to have a centroid. This centroid appears to be in a more constant spatial position regardless of the viewing angle as compared with the apparent position of this centroid with other assemblies.

Abstract: Apparatus and a method for testing tiered digital multiplexing apparatus. To test a primary train of tiered demultiplexers, a data path assurance train of demultiplexers and a selector is used to generate a demultiplexed signal for comparison with a primary demultiplexed signal. To test a primary train of tiered multiplexers, the output of the final multiplexing stage is connected to the input of the data path assurance train of demultiplexers to generate a demultiplexed signal for comparison with a primary input signal to the primary multiplexer train. Advantageously, a simpler, more reliable, and less expensive data path assurance circuit using the same types of components as the primary multiplexers and demultiplexers can be used to detect failures in these primary units as well as the data path assurance circuit.

Title: Method of creating and searching a molecular virtual library using validated molecular structure descriptors
Inventor: CRAMER RICHARD D
IPC: G16C20/62
Filed: 1997-01-27
Granted: 2004-07-20
Abstract: The problem of how to select out of a large chemically accessible universe molecules representative of the diversity of that universe is resolved by the discovery of a method to validate molecular structural descriptors. Using the validated descriptors, optimally diverse subsets (5) can be selected. In addition, from the universe, molecules with characteristics similar to a selected molecule can be identified (3). The validated descriptors also enable the generation of a huge virtual library of potential product molecules which could be formed by combinatorial arrangement of structural variations and cores. In this virtual library it is possible to search billions of possible product compounds in relatively short time frames.

Title: Golf club-distance selector
Inventor: FONG WING SON
IPC: A63B57/00
Filed: 1998-09-02
Granted: 2001-10-02
Abstract: A golf club-distance selector, custom tuned by a golfer for personalized use, comprises a base disk, on which are successively and concentrically located an intermediary and windowed disk. After performing several golf shots with a selected club, shots which are characterized by the lengths the normal golf ball fly through the air, an average length value is estimated and identified on the base disk. This value is matched with the selected club inscribed on the intermediary disk. The base and intermediary disks are attached in the above position, thereby "locking" the selected golf club to the average length value, simultaneously "tailoring" all the other golf clubs to the individual's golf swing, thus personalizing the selector. An aperture is provided on the windowed disk, indicating a length, and a golf club, far normal playing conditions. Also indicated for the same length are other golf clubs for different playing conditions.      The selector comprises the full range of golf clubs.

Abstract: A graphite powder has surface closed-end structures in which the graphite c-plane layers of the graphite layer crystal lattices have closed-ends on the surface of the graphite powder by linking the ends of one or more pairs of the c-plane layers, leaving interstices which are open on the surface of the graphite. The number of open interstices is at least 100 and at most 1500 per micrometer in a c-axis direction of the graphite.      Preferably, the graphite powder has a specific surface area of 1.0 m2/g or less. Such a graphite powder can be prepared either by graphitizing a carbon material, which has been pulverized at a high speed under well-controlled conditions before and/or after the carbonization, or by subjecting a carbon material, which has been pulverized under well-controlled conditions before and/or after the carbonization, to graphitization and then to oxidative heat treatment at a temperature of 600 - 800°C and finally to heat treatment at a temperature of 800°C or higher in an inert gas. The graphite powder can be used to produce negative electrodes of lithium ion secondary batteries having a high discharge capacity of at least 320 mAh/g and a high charge/discharge coulombic efficiency of at least 90%.

Abstract: A system, method and mobile station in a telecommunications system for handling communication requests in the form of call attempts and attempts to send text messages from a requesting party to the mobile station where the mobile station is unreachable via a normal-power-level page signal. After the mobile station has failed to respond to at least one normal-strength, first page signal, a subscriber database is consulted to determine if the mobile station is attached to the telecommunications system. If the mobile station is attached, an identifier associated with the requesting party is compared with the contents of a communication screening list associated with the mobile station to determine whether a second, higher-power page signal, called a High-Power Notification (HPN) page, may be sent to the mobile station. If so, the mobile station is paged through the HPN page signal, either via a terrestrially-based part of the telecommunications system or through a satellite-based part of the telecommunications system.
