Patent CA-2542038-A1 (CA)
Inventor: ARTHERHOLT DANNY LEE
IPC: E21B33/12
Filed: 2006-04-05
Abstract: A cup tool for use with a high-pressure mandrel of a wellhead isolation tool has a three-part packoff assembly that slides over a cup tool tube from an unset position to a set position. The three-part pack off assembly includes an elastomeric cup, a rigid alignment ring located above the elastomeric cup and an elastomeric packoff element located above the rigid alignment ring. The rigid alignment ring helps ensure that the elastomeric cup remains correctly aligned in a casing or tubing that is not straight, is out of round or is washed, and helps ensure that the elastomeric packoff achieves a high-pressure seal in the set position, even under adverse downhole conditions.

Title: Data demodulation for a cdma communication system
Inventor: LI TAO
IPC: H04B1/707
Filed: 2004-10-18
Abstract: An integrated circuit that performs data demodulation on partially despread symbols includes a despreading unit (620), a channel compensation unit (640), and a symbol combiner (650). The despreading unit (620) despreads input samples and provides despread symbols for a first code channel with a first spreading factor. The channel compensation unit (640) multiplies the despread symbols with channel estimates and provides demodulated symbols. The symbol combiner (650) combines groups of demodulated symbols to obtain recovered data symbols for a second code channel with a second spreading factor that is an integer multiple of the first spreading factor. The channel compensation and symbol combining are dependent on whether or not transmit diversity is used.  For a TDM design, despread symbols for multiple first code channels are processed in a TDM manner, one channel at a time, to obtain recovered data symbols for multiple second code channels. The channel compensation unit and symbol combiner can be operated in a pipelined manner.

Patent CA-2549546-A1 (CA)
Title: Aerosol valve actuator
Inventor: KOLANUS GUNTER
IPC: B65D83/14
Filed: 2004-12-17
Abstract: An aerosol valve actuator with an enclosure, an aerosol valve stem engaging portion, a product dispensing opening, and a flexible and expandable product conduit extending between the valve stem engaging portion and the product dispensing opening. The product conduit is molded at least in part of a first expandable and flexible plastic material which is softer than a second plastic material of the remainder of the actuator. The remainder of the actuator is first molded, followed by molding the first plastic material to form at least a part of the product conduit. After the actuator has been actuated to dispense a foaming product and actuation ceases, the post-foaming product expands within rather than outside the product conduit since the conduit itself expands to absorb the product expansion. Thereafter, when the next actuation occurs, the post-foaming product in the product conduit merely exits the actuator outlet as it is forced out by the product in the container being dispensed The actuator of the present invention may have a cap and a base, each with a product dispensing opening in its side wall. These openings are aligned upon actuation, but misaligned after actuation so that the post foaming of the product in the product conduit cannot then exit the actuator and the foaming expansion in the conduit is taken up by expansion of the product conduit itself. The base of the actuator includes a side wall with a plurality of inwardly flexible members. The cap has a plurality of internal ramps. When the cap slides downward on the base to initiate actuation, the cap ramps flex the base side wall flexible members inwardly. After actuation ceases, the base flexible members act against the ramps to bias the cap to slide upwardly on the base. The base has an upper portion and a lower portion connected together by one or more flexible tab members that allow the upper portion to be depressed in relation to the lower portion to actuate the aerosol valve. The valve stem engaging central tube is located in the upper portion of the base. When the cap is manually depressed to slide downwardly on the upper portion of the base, it reaches the position where the cap and base product dispensing openings are aligned. When the cap is further depressed, it forces the upper portion of the base to telescope within the lower portion of the base, at which point the central tube of the upper portion actuates the valve stem to initiate product dispensing.

Title: Reoptimization triggering by path computation elements
Inventor: GOGUEN ROBERT
IPC: H04L45/42
Filed: 2005-03-10
Abstract: A mechanism to alleviate bandwidth fragmentation in a network employing path computation element(s) to place MPLS Traffic Engineering tunnels. One application is a multiple Autonomous System or multiple area network employing distributed computation of MPLS Traffic Engineering LSPs. A particular path computation element may determine that bandwidth fragmentation is present based on monitoring of path computation failures where desired paths are blocked due to bandwidth constraints. In response to the detected bandwidth fragmentation condition, the path computation element floods a routing notification within its Autonomous System or area. Nodes respond to the routing notification by requesting reoptimization of their own previously requested Traffic Engineering LSPs allowing the path computation element an opportunity to alleviate bandwidth fragmentation.
