Title: Dispenser for patient infusion device
Inventor: FLAHERTY J CHRISTOPHER
IPC: A61M5/28
Filed: 2003-03-31
Abstract: A device (10) for delivering fluid such as insulin to a patient. The device (10) includes an exit port assembly (70), a syringe-like reservoir (30) including a side wall (32) extending towards an outlet (36) connected to the exit port assembly (70). A threaded lead screw (202) is received in the reservoir (30) and a plunger (204) has an outer periphery linearly slideable along the side wall (32) of the reservoir (30) and an inner periphery threadedly received on the lead screw (202). The plunger (204) is non-rotatable with respect to the side wall (32) such that rotating the lead screw (202) causes the plunger (204) to advance within the reservoir(30) and force fluid through the outlet (36). The device (10) also includes a dispenser (40) having a return element for causing rotation of the lead screw (202), and a shape memory element (220). A changeable length of the shape memory element (220) decreasing from an uncharged length to a charged length resets the return element.

Patent CA-2485035-A1 (CA)
Title: Gas recovery apparatus, method and cycle having a three chamber evacuation phase and two liquid extraction phases for improved natural gas production
Inventor: REITZ DONALD D
IPC: E21B43/18
Filed: 2004-10-18
Abstract: Natural gas produced from a well by executing a multiple-phase gas recovery cycle which includes a phase during which a relatively lower evacuation pressure is applied within three chambers in the well to assist in accumulating liquids at a well bottom, followed by a liquid reduction phase which clears the liquid from two of the chambers while leaving the liquid in the third chamber. The remaining liquid is thereafter lifted in subsequent liquid capture and liquid removal phases. The liquid reduction phase clears the fluid from the well more effectively with less interruption in the production of gas from the well while maintaining the full gas productivity of the well.
Patent CA-2485922-A1 (CA)
Inventor: MAAS WILHELMUS G TH M
IPC: B25B27/10
Filed: 2004-10-26
Abstract: A high strength reinforcing bar splice uses a contractible jaw assembly bridging the bar ends to be joined. The jaw assembly includes interior teeth designed to bite into the projecting ribs or deformations on the outside of the bar ends which form the overall diameter of the bar but not the core or nominal diameter of the bar. The jaw assembly is constricted from both axial ends by driving tapered locking collars on each end of the jaw assembly with a tool while concurrently causing the jaw assembly to constrict and bite into the bar ends. When the tool is removed, the collars remain in place locking the jaw assembly closed. The splice provides not only high tensile and compressive strengths but also has good fatigue and dynamic strength to qualify as a Type 2 coupler.

Title: Mac protocol with duty-cycle limitation for portable devices to comply with specific absorption rate (sar) limits
Inventor: ALAPURANEN PERTTI O
IPC: H04W4/02
Filed: 2003-06-04
Abstract: A system and method for medium access control (MAC) protocol which controls transmissions in wireless devices (102) to at least substantially comply with specific absorption rate (SAR) limits. The system and method of MAC protocol uses "source-based" time averaging measurements of transmitter "on-times" and an integral of transmission power to direct transmitter duty-cycle such that SAR limits are met. The system and method monitors and controls topology-dependent functions of a node transceiver, including transceiver duty cycle, transceiver transmit power levels and transceiver power-time products, using an automatic transmission control protocol (ATP) to vary functions to maintain specific absorption rate (SAR) limits for handheld and portable devices which are used close to human bodies. In cases in which SAR limits are approached, the ATP can direct the transceiver at the device to adjust each function, or combination of functions, to maintain an acceptable SAR limit.

Title: Encoding and decoding of digital data using cues derivable at a decoder
Inventor: RAMCHANDRAN KANNAN
IPC: H04N19/94
Filed: 2003-09-05
Abstract: Encoding digital data by using cues at a decoder (104). An encoder (102) selects an index to indicate a target codeword (112) from the complete space of all codewords to a decoder (104). The index identifies a group or a set of codewords that contain the target codeword. The sets are represented by a bit-length thus achieving compression. Two or more codewords in such a set are separated by a predetermined distance and all such sets of codewords considered together form the complete space of all codewords. The encoder sends syntax information (114), including the index, to specify the decoding.  The decoder then uses a set of candidate cues in a comparison operation to determine the target codeword from the indexed set. Processing complexity can be allocated among the encoder, decoder and other possible devices as, for example, in a digital network.
Patent CA-2498456-A1 (CA)
Title: Cyclone dust collecting apparatus
Inventor: OH JANG-KEUN
IPC: F15D1/00
Filed: 2005-02-25
Abstract: A cyclone dust collecting apparatus has a cyclone body having an air inlet for drawing in, contaminant-laden air and an air outlet connected with a vacuum suction source. The vacuum provided by the vacuum source draws air from the air outlet, which passes through the cyclone body from the air inlet. As the air flows through the cyclone body, it forms a whirling stream in the cyclone body. The whirling stream creates a centrifugal force on particles that are suspended in the air, which, because of their greater mass, causes them to become separated from air that is drawn out of the whirling stream and into the air outlet by the vacuum source. The air outlet is provided with a passage guide member arranged in the air outlet that reduces the speed of air discharged via the air outlet and also for guiding a flow streamline. The passage guide member reduces a pressure loss by a turbulence flow generated during discharging a cleaned air such that load of vacuum suction resource decreases and power consumption for operating the cyclone dust collecting apparatus can be reduced.
