Title: Quick release and fastening cover
Inventor: LACONTE RICHARD J
IPC: E05B65/00
Filed: 1999-11-24
Abstract: A quick release and fastening panel assembly includes a panel that covers a structural opening and is securely fastened to the structure surrounding the opening by a release and locking assembly.

Patent CA-2351157-A1 (CA)
Inventor: KOCHIE PATRICK S
IPC: E05F15/14
Filed: 2001-06-21
Abstract: A security system for control access of multiple users to a selected area combines rotating electronic security code or equivalent technology with an automatic self-learning receiver. The first transmitter is "learned" by the receiver manually, but subsequent transmitters are learned without the need for actuating the conventional "manual learn" mode of the receiver. Instead, by simply sending the transmit signal twice within a fixed time period, users of the subsequent transmitters use "self learning" circuitry (interposed between conventional transmitter and re-ceiver technology) in a way that is relatively transparent to the user. Other aspects of conven-tional systems are provided, such as separate control via computer or otherwise of an authorized list of uniquely-identified transmitters. In alternative embodiments, even the first transmit-ter/controller can be programmed into the receiver (such as at the time of manufacturing or in-stalling the system).

IPC: H04B7/26
Filed: 1999-12-06
Abstract: Mobile stations in communication with several base stations in a cellular CD MA system (as when undergoing soft handoff) do not use the conventional "or of the downs" rule for assessing power control commands from base stations. Mobile stations assess the link quality of the links from the base station. If any base station displays link quality above a predetermined threshold and i f that base station is requesting power reduction, power is reduced by a predetermined amount, delta. Otherwise, power is adjusted up or down by an amount less than or equal to delta according to the received power control signals from each base station in conjunction with a weight determined from the signal quality of the link from each base station.
