Patent CA-2287685-A1 (CA)
Inventor: SZURKOWSKI EDWARD STANLEY
IPC: H04M3/00
Filed: 1999-10-28
Abstract: A technique for dynamically adjusting the attributes of a DSL communications channel to satisfy varying bandwidth allocations and/or symmetry requirements. More particularly, the symmetry and/or bandwidth allocation across a communications channel, e.g. a local loop, is dynamically adjusted to satisfy particular communications transmission requirements. The dynamic adjustment of the symmetry and/or bandwidth allocation is made as a function of monitoring of the real-time usage pattern across the communications channel. Further, the dynamic adjustment of the symmetry and/or bandwidth allocation can also be made as a function of a request received from a particular application employing the communications channel. Advantageously, both symmetric and asymmetric DSL applications are satisfied across the same communications channel by dynamically adjusting the available bandwidth and/or symmetry of the communications channel.

Title: System for providing guaranteed wireless communication service to priority wireless communication subscribers
Inventor: MCCORMICK MARK ALAN
IPC: H04W4/90
Filed: 2000-04-05
Abstract: The system for providing guaranteed wireless communication service to priority wireless communication subscribers provides the capability to restrict access to wireless communications services to a selected set of subscribers, such that their access to wireless communication services is not interruptible.  This is accomplished by provisioning the cell sites of a wireless communications system into a plurality of service priority groupings, with wireless subscribers being assigned a one of the plurality of service priorities. The wireless service provider can manually activate the system to provide guaranteed wireless communication service for subscribers in a selected one or more of the service priorities in response to the occurrence of an emergency. Alternatively, the system can automatically engage in response to a traffic overload condition to ensure that emergency service personnel have immediate access to wireless communication services, regardless of the presence of an emergency situation that impacts the traffic load on the wireless communication system. The wireless subscribers who have been assigned a predetermined service priority are provided with access to reserved wireless communication capacity in the wireless communication system by either reserving a predetermined amount of wireless communication capacity for the use of the priority wireless subscribers or dynamically reserving wireless communication capacity by denying access to wireless communication subscribers when they attempt to initiate a wireless call connection in the impacted call coverage area.

Title: Method and device for verifying the workability of a safety device
Inventor: HOGSTROM KARL-KRISTIAN
IPC: G05B23/02
Filed: 1998-10-07
Abstract: The invention relates to the maintenance of safety devices. Valves and similar automatic mechanical safety devices normally maintaining a fixed position are in danger of getting stuck, and consequently may not be fully operable in an emergency situation. In a system according to the invention, real-time data indicating the operability of, for example, a valve actuator, is provided. When a fault is discovered, it can be localized using online diagnostic tools. A standby state is continuously maintained, as the unit for activating the safety function is independent of the unit for monitoring the operability, and the latter is bypassed in an emergency situation.

Inventor: MIXON DAVID A
IPC: C03B19/14
Filed: 2000-11-27
Abstract: The invention provides a process capable of heating sol-gel tubes, or other bodies, in a manner that both limits the amount of undesirable condensation on cooler surfaces and also promotes heating and treatment with gaseous reactants in a uniform manner. In one embodiment, the process involves the steps of providing a furnace comprising a tubular muffle having an opening at one end; placing tubes or other bodies into the muffle through the opening; placing within the muffle, just inside the muffle opening, a cylindrical heat and gas shield, e.g., a plug; sealing the muffle opening with a door; heating the tubes; and treating the tubes by directing the gases through a feed hole located in the door or elsewhere in the muffle. The heat-gas shield controls the amount of heat reaching the door, thereby maintaining the integrity of the o-ring. It is also possible in other embodiments for the shield to control the extent to which both process gases and condensable materials driven from the tubes are able to back diffuse toward the muffle door, thereby reducing or avoiding condensation of the materials on the door as well as undesirable reactions between the process gases and the o-ring seal.
