Patent CA-2303853-A1 (CA)
Inventor: CLARK RON
IPC: A61F2/08
Filed: 1998-09-24
Abstract: A pin (20) and method for use are provided for securing a replacement ligament (24) inside a tunnel (10) of a receptor bone (36). A threaded section (30) of the pin (20) engages and anchors the pin (20) in the receptor bone (36). A first taper (26) opposite the threaded section (30) is configured to enter a drilled hole (14) which is transverse to the tunnel (10), capture a looped replacement ligament (24), and extend into the medial side (25) of the receptor bone (36). A second taper (28) urges the replacement ligament (24) against the wall (15) of the tunnel (10) and provides resistance when the second taper (28) contacts the medial side (25) of the bone (36), thus signaling that the pin (20) has been inserted to the proper depth. The body (21) of the pin (20) secures the looped replacement ligament (24) in the tunnel (10) and holds the replacement ligament (24) in contact with the wall (15) of the tunnel (10) to insure ingrowth.

Title: Transaction notification system and method
Inventor: PALMQUIST JOHN MARK
IPC: G06Q20/00
Filed: 2000-06-20
Abstract: Communicating commands and/or data to a remote controller, such as a programmable logic controller, coupled to a cellular communications device by sending multiple pages via a cellular network control channel of a cellular mobile radiotelephone system. Each cellular communications device operating within the coverage area of the cellular mobile radiotelephone system can monitor the cellular network control channel for a pair of target pages within a first time period.  Each target page includes a specific identifier assigned to one or more of the cellular communications devices. In the event that a cellular communications device receives target pages having a matching specific identifier, the device will monitor the cellular network control channel over a second time period for at least one command page or data page carrying instructions or information for use by the remote controller. The cellular communications device can respond to the reception of one or more command or data pages by forwarding the instructions or information to the controller via a communications link. In addition, the cellular communications device can acknowledge receipt of the data or command pages by issuing an acknowledgment signal formatted as an Autonomous Registration signal via the cellular network control channel.
Patent CA-2312304-A1 (CA)
Title: Digital broadcasting receiver
Inventor: HASHIMOTO AKINORI
IPC: H03L7/06
Filed: 1998-12-04
Abstract: A digital broadcasting receiver is provided which can reproduce a carrier quickly and capture a desired signal at high speed. A carrier reproduction phase error detection circuit (6) detects a phase error voltage in accordance with a demodulation output obtained by demodulating a demodulated wave of a modulated wave during a predetermined section in a header section. A peak number calculation circuit (92) calculates an error frequency between a desired reception frequency and a reproduction carrier frequency in accordance with the phase error voltage. A differential coefficient calculation circuit (94) calculates the polarity of the error frequency. A step frequency control circuit (96) converts the calculated error frequency having the calculated polarity into a step frequency width for automatic frequency control. The reproduction carrier frequency is scanned at the converted step frequency width until a frame sync is established after the frame sync is detected. It is therefore possible to reproduce the carrier quickly and capture the desired signal at high speed.

Title: Self sealing firestop coupling assembly
Inventor: CORNWALL KENNETH R
IPC: F16L5/04
Filed: 2000-07-07
Abstract: A firestop coupling assembly (10 or 210) for allowing the passage of utility members (50 or 52) through a penetration in a partition (54 or 56) while preventing the transmission of fire and smoke through the penetration. The coupling assembly includes an outer sleeve (12 or 212) and an inner conduit (16 or 216). The outer sleeve has a concentric indention (12D or 212D) around its inner surface within which is mounted an intumescent material (20 or 220). In one (1) embodiment, the inner conduit is mounted in the open top end of the outer sleeve so that the second end (16B or 216B) of the inner conduit is adjacent the intumescent material. In another embodiment, the inner conduit is adjustable along the length of the outer sleeve. A plug (22 or 222) can be provided in at least one end of the inner conduit allowing passage of at least one (1) utility member through the assembly. In another embodiment, the inner diameter of the inner conduit is only slightly greater than the outer diameter of the utility member so that the utility member can be solvent welded to the inner surface of the inner conduit. When the coupling assembly is exposed to heat, the intumescent wrap expands into the inner passageway of the outer sleeve and prevents the transmission of smoke end fire through the coupling assembly.

Patent CA-2316525-A1 (CA)
Inventor: IENAKA TAKUYA
IPC: G02B6/34
Filed: 1997-03-27
Abstract: An optical waveguide grating with radiative mode-coupling properties, with exceptional stability and reliability as an optical component, wherein the central wavelength of the rejection band has a low temperature dependence, due to the use of silica glass doped with germanium and boron for the core.      The rejection bandwidth can be narrowed without increasing the grating length by forming the radiative mode-coupled optical waveguide grating in an optical waveguide wherein the mean relative refractive index difference of the core is greater than that of optical communication waveguides. The rejection can be increased by reducing the occurrence of cases wherein propagation modes of the core coupled to cladding modes once again couple to the core in planar optical waveguide gratings formed by making periodic changes in the waveguide structure along the direction of propagation of light in an optical waveguide having a cladding with a lower refractive index than the core surrounding the core, by making the thickness of the cladding at least thirteen times the thickness of the core.

Abstract: The moulding tool comprises a plurality of components which are connected to one another and form a flexible string. The tool incorporates actuating means which pulls the components into an abutting relationship in which the tool has the form of a rigid string. The actuating means can comprise electromagnets.  When power is supplied the electromagnets pull the components together.  Alternatively a passageway through the tool, constituted by a passage in each component, can be connected to a source of suction. As the passageway is evacuated, the components are drawn together. The tool is used in a preform mould. Once the preform has been moulded, it and the tool embedded in the preform, are removed to a blow mould and the preform blown. The tool is then returned to its flexible string form. It can then be withdrawn from the bottle through its neck.

Title: Combined channel coding and space-time block coding in a multi-antenna arrangement
Inventor: NAGUIB AYMAN F
IPC: H04L1/00
Filed: 1999-08-23
Abstract: Enhanced performance is achieved by combining channel coding with the space-time coding principles. With K synchronized terminal units transmitting on N antennas to a base station having M $m(G K) receive antennas, increased system capacity and improved performance are attained by using a concatenated coding scheme where the inner code is a space-time block code and the outer code is a conventional channel error correcting code. Information symbols are first encoded using a conventional channel code, and the resulting signals are encoded using a space-time block code. At the receiver, the inner space-time block code is used to suppress interference from the other co-channel terminals and soft decisions are made about the transmitted symbols. The channel decoding that follows makes the hard decisions about the transmitted symbols. Increased data rate is achieved by, effectively, splitting the incoming data rate into multiple channels, and each channel is transmitted over its own terminal.
