Patent CA-2504495-A1 (CA)
Inventor: JUPP DAVID J
IPC: F17C13/06
Filed: 2005-04-20
Abstract: A sealing system for a high pressure fuel cylinder has an inner seal and an outer seal sealing an insert into a boss of the cylinder. Permeation rates as a result of the differential pressures across the seals are balanced across both the inner and outer seals to maintain a constant pressure in an intermediate space between the seals. Permeation is balanced by selecting suitable seal materials or by seal geometry or by providing a pressure relief device to the intermediate space to release excess pressure built up in the intermediate space beyond a desired intermediate pressure.     Maintaining the intermediate pressure lower than the cylinder pressure and higher than atmospheric pressure results in lower pressure differentials across the seals, extending the seal life. A pressure switch or gauge is provided to monitor the pressure in the intermediate space. Changes in the pressure are indicative of a leak in one or both of the seals.
Patent CA-2505460-A1 (CA)
Title: Device authentication
Inventor: DAVIS DINAH L M
IPC: H04Q7/36
Filed: 2005-04-27
Abstract: Authentication of two devices in communication with a third device is achieved where the first and second devices each possess a shared secret value. The authentication includes communication of authentication values from the first device to the second device using the third device. Similarly, there is communication of values from the second device to the first device using the third device. The third device retains the communicated values. The values are calculated to permit the third device to authenticate the first and second devices without the third device receiving the shared secret value. The authentication may be used to establish a communications channel between the first and the second devices.

Title: Controlled superposition coding in multi-user communication systems
Inventor: LAROIA RAJIV
IPC: H04J99/00
Filed: 2004-02-19
Abstract: Methods of using superposition coding in a communications systems, e.g., a multi-user communications system. Superpostion coding in accordance with the invention occurs in the case of an uplink (1212, 1216) by transmissions of different wireless terminals (1204, 1206) transmitting using the same communications resource, e.g., simultaneously transmitting using the same frequencies. The signals combine in the communications channel resulting in one transmission being superimposed on the other transmission. The device, e.g., base station (1207), receiving the superimposed signals uses superposition decoding techniques to recover both signals. To obtain the benefit of the superposition, assignments of channel segments to multiple wireless terminals is controlled by the base station and/or transmission power levels are controlled by on or more wireless terminals sharing the same uplink communications resource, e.g., time slot, to make sure that the received signals from the different devices will have different received power levels making superposition decoding possible.

Title: Method and apparatus for utilizing historical network information for mitigating excessive network updates when selecting a communications channel
Inventor: LIU XIN
IPC: H04W52/02
Filed: 2005-08-23
Abstract: A method and apparatus utilizing historical network information for mitigating excessive network updates when performing channel selection between a serving base transceiver station and an adjacent base transceiver station when determined channel selection would result in either a Location Area Update (LAU) or a Routing Area Update (RAU) is presented. If a network update, either LAU or RAU, is the first occurrence, network identification information for the LA or RA is stored and an incremental value indicating occurrence is set; else in the case occurrence is not the first, the incremental value is incremented. A first margin value is then selected if the incremented value does not meet or exceed a predetermined value, or a second margin value is selected if the incremented value does meet or exceed a predetermined value. The signal level of the adjacent base transceiver station is then compared to the reference signal level of the serving base transceiver station plus the selected margin value in order to determine channel selection.

Filed: 2004-03-04
Abstract: A lottery game having a first pool of numbers and a second pool of numbers.  The lottery operator picks a predetermined number of selections out of the first pool and each player of the lottery game also picks out the same predetermined number of selections out of the first pool. The lottery operator picks two, or more, selections out of the second pool while each player is allowed to pick only one selection out of the second pool. The jackpot prize is won by matching all selections from the first pool and any of the lottery operator selections out of the second pool. By adjusting the number of selections in each pool, the prize structure of the novel lottery game increases the amount of money awarded to jackpot and lower range subordinate prizes and decreases the amount paid to intermediate range subordinate prizes.

Title: Controlling data security procedures using an admission control signaling protocol
Inventor: ORAN DAVID R
IPC: H04L12/56
Filed: 2004-04-27
Abstract: Providing data security involves receiving a request message at an intermediate network node. The request message is associated with a number of data packets from a communication device. The intermediate network node determines whether the request message has a satisfactory security hint. If the request message does not have a satisfactory security hint, the intermediate network node performs a security procedure on the data packets.  If the request message has a satisfactory security hint, the intermediate network node relies on a security transform present in the data packets and routes the data packets without performing the security procedure.
