Patent CA-2420269-A1 (CA)
Inventor: HEMPFLING DAVID C
IPC: F16B33/02
Filed: 2003-02-27
Abstract: A threaded fastener includes a lead having bosses separated from one another by bases along the thread crest. The lead-in and lead-out profiles of the bosses, and other features of the bosses and bases may differ from one another along the fastener shank. The lead-in and lead-out profiles may have linear and non-linear surfaces. The lead-in and lead-out profiles may have cutting edges angled toward the direction of propagation of the bosses. The boss profiles may be selected to reduce insertion torque and to provide excellent resistance to pullout. The fastener may be formed by roll threading via a tool made by a plunge EDM process.
Patent CA-2422715-A1 (CA)
Inventor: XU DONNA D
IPC: H04L12/56
Filed: 2001-08-16
Abstract: The invention provides a novel protocol suite for supporting micro-mobility within a radio access network (RAN). The protocol suite and comprises three separate protocols, namely a Mobile Registration Protocol, a Handoff Affected Router Discovery Protocol (HARDP) and a Mobile Location Update Protocol. The Mobile Registratio Protocol is used to register mobile terminals within a RAN  while the Mobile Location Update Protocol is used to update mobile terminal reachability during a handoff. The HARDP protocol is used at network boot-up time to identify a subset of routers that needs to be updated when a mobile terminal handoff occurs between two neighboring radio access nodes.

Title: Energy saving electrical power control device and method
Inventor: GIBSON J ALAN
IPC: H02M5/293
Filed: 2003-04-09
Abstract: An electrical load power control device is described that reduces the power consumption of inductive and inductive-dissipative loads, including for example fluorescent lighting. The power circuit of the invention interrupts AC power supply to the load during a plurality of intervals within each half cycle of the AC  mains signal frequency whilst providing an alternate path for current flow during the interruption to maintain a sinusoidal-like current to the load. During a crossover lag interval encompassing zero crossing points of the voltage and current and during which the voltage and current have opposite polarities, both elements of the power switch are switched to the "on" condition, one element of the circulating switch is switched to the "on" condition when a positive current is flowing in the load and the other element of the circulating switch is switched to the "on" condition when a negative current is flowing in the load. The power factor presented by the load is unaffected and other current parameters of the load such as form factor and total harmonic distortion may be desirably modified. In the preferred embodiment an oscillator has a duty cycle control circuit which deactivates the power switch and simultaneously activates the circulating switch during a predetermined portion of the oscillator duty cycle. The duty cycle establishes the amount of power reduction.

Title: Electrostatic spray device
Inventor: MORI TAKESHI
IPC: B05B5/16
Filed: 2002-01-11
Abstract: An electrostatic spray device that maintains a consistent charge-to-mass rat io in order to maintain a consistent target spray quality is disclosed. During steady state conditions, the high voltage power supply adjusts the output voltage level in response to changing environmental and/or operating conditions. During transient conditions such as start-up, shut-down and changing flow rate conditions, the high voltage power supply ensures that th e charge-to-mass ratio is maintained. During, start-up, for example, the high voltage power supply charges the high voltage electrode to a predetermined voltage level before the product is delivered to the charging location. Duri ng shut-down, the product delivery is stopped before the high voltage power supply shuts off power to the high voltage electrode, and during changes in product flow rate, the voltage level of the high voltage electrode is adjust ed to maintain a consistent charge-to-mass ratio. The present invention also prevents afterspray by discharging the stored charge remaining in storage elements of the high voltage power supply.

Filed: 2003-12-04
Abstract: A data backup system for backing up a data file from a source device having a source processor and an input device to a target device having a target processor and a database over a communication network. The source processor determines whether the data file has been modified, and if so, determines the modified data block(s). The modified data block(s) are transmitted from the source processor to the target processor over the communication network. The target processor receives the modified data block(s) from the source device over the communications network, and uses the modified data blocks to construct the data file, and to store the data file on the database. Concurrently, it is determined if the input device is active at any time during the backup process, and if so, the backup processing is interrupted until the input device has been inactive for a predetermined period of time.

Filed: 2004-03-24
Abstract: A process is described for in situ recovery of bitumen or heavy oil from a reservoir having a horizontal injection well and a horizontal production well. The process includes a first phase in which steam and a heavy hydrocarbon solvent are injected into the reservoir, a second phase in which the steam and heavy hydrocarbon injections are transitioned to a light hydrocarbon solvent injection, and a third phase in which a light hydrocarbon solvent is injected without further steam or heavy hydrocarbon injection. A  displacement gas may be added during any of the phases, and production of hydrocarbons continues throughout all phases. The process allows maximal economic benefit by employing a high-production start-up phase, followed by lower cost phases which progress a depletion chamber within the reservoir to achieve high levels of reservoir fluid recovery.
