Title: Architecture for network manager
Inventor: KAIROUZ JOSEPH
IPC: G06F13/00
Filed: 1998-06-03
Abstract: A distributed network management architecture, where a plurality of network managers share information about network elements by building the necessary infrastructure to discover alternate routes to element controllers when possible. A large number of network elements and operation controllers or managed object agents spans are simultaneously accessible to multiple graphical network browser instances on physical workstations. Each network manager can manage an element controller directly, through a direct connection, or indirectly, through an indirect connection to a second network manager which directly manages that element controller. As well, a plurality of telecommunication networks can be federated for transparently increasing the number of users and the reliability of each network. By allowing each network manager to be configured individually, more flexibility over both engineering and survivability is achieved.

Abstract: A wellhead safety valve control system for opening and closing subsurface and surface safety valves in a predetermined sequence and certain components used with such control system. Dump valves in both latching and non-latching configurations are utilised within the control system. Embodiments of the dump valve mag incorporate a time delay feature to ensure the subsurface safety valve is closed after a desired time period following the closure of the surface safety valve in the event of flowline anomalies.      Provision is made for independent closure of the surface safety valve without closure of the subsurface safety valve.

Title: The dental flosser and dispenser
Inventor: PABLO GERARDO Y
IPC: A61C15/04
Filed: 1999-11-23
Abstract: Our invention relates to a "DENTAL FLOSSER AND DISPENSER". A particular application is for the device to be able to effectively floss and clean one's teeth free of food debris, plaque, tartar, and other such material imbedded in-between one's teeth, in particular after having a meal.  The device's main focus is to replace the awkward use of tying and twining of the dental floss thread into one's fingers and hands (left) into the other one's fingers and hands (right) to floss one's teeth. The invention is designed not only to eliminate the use of ones hand in flossing but also to dispense the dental floss thread in a highly, effective, calibrated manner. The device, with its unique design, is able to both hold and dispense the dental floss thread in an easy, simple motion. Because of the nature of its intended use and purpose for personal use in one's oral hygiene and dental care and for safety and health concerns, the device is designed and manufactured for use as a one-time use disposable item. The device is recommended for individual use only and recommended for use much like a toothbrush in a personal way.
Patent CA-2291455-A1 (CA)
Inventor: MARSHALL ROBERT E
IPC: H01R13/658
Filed: 1999-12-02
Abstract: An electrical connector that may be surface mounted to a circuit board that includes a housing having an outer shielding and mounting posts formed at a base of the connector. The outer shielding surrounds the housing and includes two "Tshaped" extensions that are formed at a bottom of the shielding. The "T-shaped" extensions are bent at approximately a 90.degree. angle with respect to the lateral walls of the housing and through an opening in the mounting posts such that the top of "T" is retained within a groove that is formed in the bottom of each mounting post. The top of the "T" has length that is longer than the diameter of the mounting post such that the ends of the "T" extend beyond the periphery of the mounting post, and are longer than the diameter of a receiving hole of a printed wiring board into which the mounting post is inserted. When the connector is mounted to a printed wiring board, the mounting posts are inserted into their respective receiving holes and the ends of the "T" that extend beyond the periphery of the mounting posts are deflected upwardly in a direction opposite of the direction of insertion to retain the connector on the printed wiring board.
Patent CA-2292400-A1 (CA)
Inventor: FIORE JOSEPH FRANK
IPC: B65D43/10
Filed: 1999-12-10
Abstract: A snap fit lid for a container is described. The lid can be made to incorporate thermal insulation and engages the container internally and at its edge to form a double seal. An annular gap is formed between the double seals. A groove runs transversely to the annular gap across the internal and external seals to allow pressure equalization in the container with its surrounding environment. The closure straddles the container at its top and snaps to the container top to create a pair of offset opposed seals for a snug fit to the container. The closure is particularly amenable to use in tray sized containers used extensively in foodservice applications.
Patent CA-2296135-A1 (CA)
Title: Testing system for circuit board self-test
Inventor: DAUDELIN DOUGLAS STREETER
IPC: G06F11/22
Filed: 2000-01-14
Abstract: A circuit pack self-testing system adapted to carry out tests on circuit pack electronic devices is disclosed. The self-testing system executes various test programs in a test suite, and keeps an historical record of test results from previous test suites in non-volatile memory. The historical record is updated only when the most recent results are different than the last-recorded results, and are easily accessible for circuit pack failure analysis and repair. At the beginning of each test suite, a temporary record for containing test results is initialized. As the system progresses through the various test programs, the test programs update the temporary record with test results. In preferred embodiment, this temporary record is created by utilizing two registers, a start register and an end register. The start register stores the beginning of each test program (test portion) in a test suite and the end register stores the ending of each test program. If a test suite runs to completion the start and end registers will contain the same value.      However, if a test program in a test suite cannot run to completion, the value stored in the start register will be one greater than the value stored in the end register.      Should a fault, possibly intermittent, on the circuit pack under test cause a test program to halt or hang, a sanity-recovery mechanism causes the self-testing system to be restarted. Prior to initializing the temporary record at the beginning of the next test suite, the temporary record is examined to determine whether a previously executed test suite failed to run to completion. If the examination shows that it failed to run to completion, and the failure information is different than the last-recorded results in the historical record, then information from the temporary record indicating this failure is stored in the historical record.

Abstract: A sensor for measuring the dielectric constant of a fluid uses time of flight measurements. The sensor has a conduit for the fluid, preferably a transmission line. The dielectric constant of the fluid affects tranmission of electrical energy along the transmission line. An electrical generator, having as output an electrical transient, is operably connected to one end of the transmission line for transmitting the electrical transient along the conduit, wherein propagation of the electrical conduit is affected by the fluid. A receiver is connected to the other end of the conduit for detecting electrical transients that have passed along the conduit from the electrical generator. A processor is operably connected to the electrical generator and to the receiver, the processor being programmed to cause an electrical transient to be generated by the electrical generator for passage along the conduit and determine the dielectric constant of the fluid from characteristics of the electrical transient detected at the receiver.
