Patent CA-2475938-A1 (CA)
Inventor: LI YONG
IPC: H04L9/00
Filed: 2004-07-27
Abstract: A RADIUS server is provided with the capability of authenticating a wireless access point whose IP network address has been dynamically allocated. One the wireless access point has received its IP network address on booting a request for authentication is sent to the RADIUS server from a wireless access point. The RADIUS server determines a MAC  address, a IP network address, and an authenticator from the request. The MAC address is used to determine a shared secret which is used to verify the message attribute authenticator for the request, which is used for verifying both addresses. The method and apparatus can be applied to other AAA server protocols, for example Diameter protocol.

Patent CA-2482308-A1 (CA)
Inventor: DE MICHELE ONOFRIO
IPC: F16K17/38
Filed: 2004-09-21
Abstract: A safety valve for pressurized tanks, particularly for tanks for containing methane or LPG for motor vehicles, comprises an open/close element (15) that is kept by elastic means (19) in a closing position, in which it does not enable communication of the internal cavity (4) of the tank with the external atmosphere.      When a pre-set maximum value of the pressure inside the tank is exceeded, sufficient for overcoming the load of said elastic means (19), the open/close element (15) is displaced from its closing position and enables discharge of the gas contained in the tank into the external atmosphere. The elastic means (19) are arranged in series with a fuse element (22) , which is set between the open/close element (15) and the valve body (5). In this way, whenever the temperature exceeds a pre-set maximum value, the fuse element (22) melts, causing unloading of said elastic means (19), which consequently leaves the open/close element (15) free to open. Preferably, associated to the open/close element (15) are sensor means for detecting the displacement of the open/close element from its closing position, which are designed to signal intervention of the safety valve to the driver.

Title: Radiotelephone system for groups of remote subscribers
Inventor: COOLEY DAVID M
IPC: H04M11/06
Filed: 1994-07-21
Abstract: A power-conserving time division multiple access (TDMA) radiotelephone system is disclosed in which a cluster of subscriber stations, remote from a base station, employs a common pool of frequency-agile modems each of which digitally synthesizes, on a time slot-by-time slot basis, the different channel-identifying intermediate needed to support communications between several of the subscriber stations and the base station. Power conservation is facilitated inter alia by controlling the assignment of modems to calls, maintaining unassigned modems in a powered-down state and by controlling the number of calls using the same time slot. Delay in assigning a powered-down modem to a call is eliminated by making available to all modems the highest quality synchronization information obtained by any of the active modems.
