Patent CA-2272072-A1 (CA)
Inventor: WILSON STUART E
IPC: H01H35/14
Filed: 1997-11-13
Abstract: A shock sensor (20) having some structural similarities to a reed switch, particularly in the use of a glass capsule (22) which hermetically seals the components of the shock sensor. The shock sensor employs a sensing mass (31) mounted on a metallic planar spring (32). Under the influence of a crash-induced acceleration, the sensing mass is driven against a fixed contact to close an electrical circuit. To extend the closure duration and increase the reliability, the contact surface (40) which is formed on the sensing mass is oriented at an angle of 60 degrees out of the plane containing the spring.

Title: Flicker photometer
Inventor: BONE RICHARD ANDREW
IPC: A61B3/06
Filed: 1998-03-04
Abstract: A flicker photometer has beam generating means (1, 8 and 4) for generating two beams of light of different colours.      Light from the beams is viewed at the viewing means, and the intensity of light of one beam relative to that of the other beam can be adjusted by adjustment means comprising an attenuating filter (20) which is movably mounted in the path of one beam.      Movement of the filter relative to the beam alters the degree to which the beam is attenuated, and is achieved using an electric motor (22). The motor provides a relatively easy means of adjusting the filter position, and can be used to provide coarse and fine adjustments in response to suitable signals from an optical encoder. The motor also enables the filter, along with the beam generating means, to be mounted on a movable table for use in enabling the photometer to accommodate both short and long-sighted subjects.

Abstract: The invention provides nutritional supplements and methods for administering nutritional supplements that improve glucose metabolism, particularly for persons with diabetes. A first nutritional supplement, or "Phase I"  supplement, comprises a source of vanadate and a source of chromium. A second nutritional supplement, or "Phase II" supplement, comprises Gymnema sylvestre and lipoic acid. The nutritional supplements are alternated to prevent accumulation of the nutrients in the body and also to overcome desensitization that can occur over long periods of continuous use. While the nutritional supplements may be alternated at almost any frequency and taken over almost any duration, it is preferred that each Phase be taken for between about 2 and about 6 months, most preferably about 3 months or about 90 days, before alternating back to the other Phase.

Patent CA-2286995-A1 (CA)
Title: Multi-level leaching system
Inventor: PRESBY DAVID
IPC: C02F1/28
Filed: 1999-10-19
Abstract: The invention most fundamentally is a leaching system substantially consisting of subsystems of liquid permeable conduit, serial or parallel interconnected for the serial or parallel flow of fluid being processed. Fluid flow is within subsystems and between subsystems from one level to another level. I.e., the subsystems of which the system is comprised are located at different depths one above the other within a "leach bed" or within the volume designed to process the leached fluid. The leaching system has at least two (2) leaching subsystems wherein each of the leaching subsystems is planarly located at a different depth within the leaching field having the leaching system installed therein. The leaching subsystems are fluid flow connected, using tubing, such that fluid being leached either flows; (1.) sequentially or serially through one of the subsystems and then sequentially or serially through another of the subsystems and subsequently through yet another subsystem until the last of the subsystems; or (2.) the fluid being leached is divided such that the divided portions flow in a parallel paths or substantially simultaneously through one of the subsystems and then subsequently through the remaining subsystems either simultaneously or sequentially and in either sequential flow or parallel flow within the components of the subsystems. The system permits a greater density of bacteria within a leaching area. The multi-level system allows a straightforward installation of a leaching system in small or irregularly shaped areas where installation of effective single level systems would be difficult or impossible.

Abstract: An optical leak detector (200) for use with a cooling system is described. The optical leak detector includes a light source (203), a light detector (205), and a conversion device (215). The light source is optically coupled to the light detector by way of an optical path (210). The light detector generates an electronic signal in response to light received from the light source. The conversion device, which is attached to the light detector, generates an electronic signal in response to the amount of light received from the light source. This electronic signal can indicate if a leak has occurred in the cooling system by the traversal of a entrapped gas bubble across the optical path formed by the light source and the light detector.

Title: Circuit set-up and caching for multimedia multipoint servers
Inventor: ST HILAIRE MARC
IPC: H04N7/15
Filed: 1998-08-20
Abstract: An MMS circuit set-up system includes a real time link manager (RTLM, 50) which is coupled to the audio video controller (AVC, 74) of the MMS. The AVC (74) receives data from MMS reservation system and sends commands to the RTLM (50) to set up connections for the conference. The RTLM (50) sends configuration messages to ATM switches and/or other networking equipment using SNMP in order to set up a conference using SNMP via an ETHERNET connection to the slot controllers of the ATM switches and networking equipment which does no support SNMP. The ATM switches are controlled by the RTLM (50) using TCP/IP via an ETHERNET connection to the servers. The ATM circuits are preferably created by adding entries to an SPVC table in the ATM switch. According to one aspect of the invention, when ATM circuits are no longer needed, the SPVC table entries are not deleted, but the status of the circuit is marked "idle". This allows the circuit to be reused with minimal set-up time when it is again needed.
