Patent CA-2437377-A1 (CA)
Title: Aircraft applicable ground fault circuit interrupter
Inventor: BAX RONALD A
IPC: H02H3/10
Filed: 2002-01-30
Abstract: The aircraft applicable ground fault circuit interrupter interrupts a circuit when a current imbalance is sensed. The circuit interrupter includes a power supply, a sensor for sensing a current imbalance at the line side of the circuit, a logic controller, and a power controller. The power supply provides power to the sensor, logic controller, and the power controller. The logic controller receives input from the sensor, and the power controller receives input from the logic controller, and interrupts power to the load side of the circuit when the sensor senses a current imbalance. Power interruption due to a sensed current imbalance is maintained until the power source is cycled. The circuit interrupter is preferably autonomous, requiring no additional signals, imputs, or sources of power.

Title: Communication system employing multiple handoff criteria
Inventor: ENGLISH SEAN
IPC: H04J13/00
Filed: 2002-06-28
Abstract: Disclosed herein is a communication system which manages guarantee of service (GOS) requirements for various users while efficiently managing backhaul network traffic and optimizing overall system capacity. In one aspect, armed handoff is used to transmit forward link data from a single base station to a particular mobile station as long as certain minimum requirements are met, such as minimum data throughput, minimum data rate, and GOS requirements. If these criteria are not met, soft and softer handoff can be employed to transmit forward link data from one or more base stations to a particular mobile station until the conditions for armed handoff are met. In another aspect, the test to add a base station sector to the active set differs based on whether other sectors of that base station already exist in the active set.  The test is less stringent when a sector is not the first of its base station to enter the active set, and more stringent when it is the first.

Title: Overflow chamber
Inventor: LECORNU PAUL
IPC: E03F5/14
Filed: 2002-10-08
Abstract: An overflow chamber (2) is provided for use in a combined sewer overflow. An inlet (12) and an outlet (14) open into the chamber (2) below a screen (20), and an overflow outlet (15) opens into the chamber above the screen. Baffles (26) are provided underneath the screen (20) across the general flow of storm water. In storm conditions, the storm water in the chamber (2) will reach the level of the screen (20), which traps aesthetically offensive material and gross solids, leaving the water to flow through the screen (20) to the overflow outlet (15). The baffles (26) circulate the storm water, and this dislodges material accumulated on the underside of the screen (20) and so helps to prevent blinding of the screen (20) in storm conditions.
