Patent CA-2292439-A1 (CA)
Inventor: ROURKE HOWARD NEIL
IPC: H04B10/297
Filed: 1999-12-16
Abstract: In a duplex WDM transmission system, an optical amplifier that uses different amplification paths for amplification of the different directions of signal propagation requires filters to keep the loop gain less than unity for all wavelengths within the amplification waveband. Simple high-pass and low-pass filters can be used when red channels are used for signals propagating in one direction, and blue ones for those propagating in the other. Comb filters are, however, required for use in any optical amplifier employed such a transmission system using any form of interleaved form of channel allocation in place of the red/blue allocation. Examples of such amplifiers are described, these amplifiers having filters possessing a tandem arrangement of an optical isolator and a series of Bragg reflection gratings.

Title: Extracellular matrix-binding proteins from staphylococcus aureus
Inventor: PATTI JOSEPH M
IPC: A61P31/04
Filed: 1998-11-25
Abstract: Isolated extracellular matrix-binding proteins, designated ClfB, SdrC, SdrD and SdrE, and their corresponding amino acid and nucleic acid sequences and motifs are described. The proteins, peptides, fragments thereof or antigenic portions thereof are useful for the prevention, inhibition, treatment and diagnosis of S. aureus infection and as scientific research tools. Further, antibodies or antibody fragments to the proteins, peptides, fragments thereof or antigenic portions thereof are also useful for the prevention, inhibition, treatment and diagnosis of S. aureus infection. In particular, the proteins or antibodies thereof may be administered to wounds or used to coat biomaterials to act as blocking agents to prevent or inhibit the binding of aureus to wounds or biomaterials. ClfB is a cell-wall associated protein having a predicted molecular weight of approximately 88 kDa and an apparent molecular weight of approximately 124 kDa, which binds both soluble and immobilized fibrinogen. ClfB binds both the alpha and beta chains of fibrinogen and acts as a clumping factor. SdrC, SdrD and SdrE are cell-wall associated proteins that exhibit cation-dependent ligand binding to the extracellular matrix. It has been discovered that in the A region of SdrC, SdrD, SdrE, ClfA and ClfB, there is a highly conserved amino acid sequence that can be used to derive a consensus motif of TYTFTDYVD.

Title: Modification of voice prompting based on prior communication in a call center
Inventor: FOSTER ROBIN H
IPC: H04M3/523
Filed: 2000-07-24
Abstract: A call center is configured such that voice prompts provided to a given caller are modified based on prior e-mail notifications or other non-telephonic communications between the call center and that caller. In an illustrative embodiment, information regarding at least one previous non-telephonic communication with a given caller is stored in a database or other memory accessible to the call center. When the given caller places a subsequent call to the call center, the call center retrieves the stored information for that caller, and selects voice prompts for the caller based at least in part on the e-mails or other non-telephonic communications previously sent to the caller. The call is then routed to an appropriately-skilled agent based at least in part on a response of the caller to the voice prompt. Additional information relating to the previous non-telephonic communication, e.g., a copy or summary of the communication, may be transmitted to the agent that receives the call.
Patent CA-2314698-A1 (CA)
Title: Timer
Inventor: AMONETT DANIEL KEITH
IPC: H01H43/10
Filed: 2000-07-28
Abstract: A cam-operated timer for a household appliance has a variety of improvements. An audible and tactile feedback member engages a textured surface on the cam wheel, to produce desired audible and tactile feedback when the timer is manually set.      When the timer is manually set, the cam-actuated switches are moved away from the cam surfaces, and a clutch is opened to permit bi-directional slip between the cam wheel and motor, so that the sole source of audible and tactile feedback is the audible and tactile feedback member. The timer also features lanced switch arm contacts, that provide a sharp contact edge to permit the switch arms to make good contact with adjacent switch arms. The switch arms are mounted in a stack of wafers, where each wafer may have switch arms of differing thickness or metal, allowing high current and low current switches to be mixed.      Features in the housing are used to receive and locate the wafers to prevent inaccuracies in wafer thickness from accumulating through the stack of wafers. Also, the motor and geartrain are reduced in size. The motor comprises a stator plate and a rotor mounted for rotation in the stator plate. The geartrain comprises meshing gears positioned on both opposite sides of the stator plate and mounted directly to the stator, for providing a gear reduction of the rotation of the motor.
