Patent CA-2188224-A1 (CA)
Inventor: BREESE DOUGLAS E
IPC: F16C3/02
Filed: 1996-10-18
Abstract: A driveshaft includes a center portion having a larger diameter, an end portion having a reduced diameter, and a diameter reducing portion positioned between the center and end portions. The reduced diameter end portion of the driveshaft is secured to a reduced diameter tube yoke. This facilitates the introduction of tooling during assembly of a universal joint. The driveshaft is formed by a method which involves first heat treating the driveshaft to a relatively soft temper, then swaging the end portion of the driveshaft, and thenheat treating the driveshaft again to a relatively hard temper. In more detail, a driveshaft is provided having a predetermined first diameter, the driveshaft being heat treated to achieve a relatively soft temper so as to possess a desired elongation factor. This allows the end portion of the driveshaft to be swaged toreduce the diameter thereof to a second predetermined diameter. After swaging, the driveshaft is heat treated again to achieve a relatively hard temper to meet the strength requirements for use.

Title: Method and apparatus for monitoring and correcting individual wavelengthchannel parameters in a multi-channel wavelength division multiplexer system
Inventor: KOCH THOMAS LAWSON
IPC: H04B10/572
Filed: 1997-02-05
Abstract: A system and associated method for determining if a channel signal carried by a discrete wavelength channel is properly centered for that wavelength channel. A signal generator is provided that superimposes a secondary signal over the original signal in a signal channel. Tone detectors are provided at a point after the superimposition of the secondary signal. The tone detectors detect the superimposed tone signal at wavelengths that are longer and/or shorter than the wavelength assigned to the wavelength channel. By measuring the degree of balance between wavelengths longer than the wavelength assigned to the wavelength channel and the wavelengths shorter than the wavelength assigned to the wavelength channel, it can be determined if the original signal is centered for that wavelength channel. If a predetermined degree of balance is not obtained, the original signal for the wavelength channel can be corrected or can be recognized as being non-compliant.

Abstract: A telecommunications system infrastructure that facilitates easy insertion of feature software into existing such telecommunications systems and easy integration of the new calling features and their implementing software with existing features and their software. The infrastructure comprises the Lucent Technologies MMCX multimedia communications server (100) and middleware-compliant communications endpoints (101-102) executing the Lucent Technologies MMCX communications middleware (111-112). Feature-implementing software has a modular client/server construction, with feature managers (server modules, 300,350) executing on the MMCX server and feature administration agents (client modules, 303-353, 304-354) executing on the endpoints. The infrastructure provides a context service (120) and a context API(121) for registering an instance of a feature manager (a user policy, 301-302, 351-352) for each user upon that user becoming entitled to the feature, an administration API(360) for communications between feature managers and feature administration agents on the user's endpoint to customize the user's user policies for the user, and a context (a cyberspace meeting room, 200) and the context API for involving the user policies of users who are parties to a call in the call and for communicating call-related events to feature servers and other service-implementing software. Call-related events are passed to user policies involved in the call, and they are given a chance to react to the events by allowing or rejecting the events. Interactions between features are managed by having feature managers register at different priorities with the context service; higher-priority modules are serially given an opportunity to allow or reject events before lower-priority modules.

Inventor: CHAN TIMOTHY Y C
IPC: A61J1/22
Filed: 1997-10-14
Abstract: This invention is a fluid depletion monitoring device. It is used to remind people to change a solution bag before it runs out completely. The inventor works in an ophthalmology operating room of a Toronto hospital. Phaco Emulsification is a fairly new technique in cataract extraction surgery (removal of an opaque lens from the eye). A small piece of instrument called ultra-sound-handpiece from the emulsifier is inserted into the eyeball. By using ultrasound, the opaque lens is fragmented into micro particles and aspirated out, and at the same time, a balanced salt solution (BSS) is infused into the eye in order to keep the eyeball in shape. This mechanism of aspiration and infusion must be maintained at all times otherwise the eyeball will collapse and serious complications will occur.
