Patent CA-2557893-A1 (CA)
Inventor: JESS PETER E
IPC: B64B1/30
Filed: 2006-08-29
Abstract: A hybrid lift air vehicle for lifting and transporting a payload to a delivery location, which comprises a helium filled envelope mounted on an airframe. Vertical thrusters are positioned on the airframe, and at least two lateral thrusters are mounted on the envelope wherein, when the vehicle is connected to the payload for transport, the helium supports the weight of the vehicle and the vertical thrusters are then continuously engaged to support the weight of the payload and to provide lift to the payload, wherein the lateral thrusters are then engaged to effect lateral movement of the vehicle to the delivery location, whereby, once at the delivery location, the plurality of vertical thrusters are slowly disengaged so as to allow the air vehicle to descend and the payload to again engage the ground surface for unloading of the payload from the vehicle, the vehicle continuing to be kept aloft, once unloaded, by the helium. In this manner, the vehicle utilizes the helium to offset the weight of the vehicle, thus allowing the vertical thrusters to provide 100% of the power to lift the payload from vertical thrusters.

Title: Engine optimisation method and apparatus
Inventor: WENG LARRY LIN FENG
IPC: F02D45/00
Filed: 2005-04-27
Abstract: An engine management apparatus for an internal combustion engine of a vehicle includes a microprocessor that is operable on adjustment mechanisms of the vehicle. The vehicle has a torque sensor for sensing torque generated by the engine and the adjustment mechanisms adjust parametric values related to the torque. Memory circuitry is accessible by the microprocessor. The memory circuitry stores data representing at least one set of parametric values and a range of torque values corresponding to respective parametric values in the set. A set of instructions are executable by the microprocessor so that the microprocessor cyclically retrieves a real time torque value from the torque sensor and updates the memory if the retrieved torque value is higher than a stored torque value corresponding to a current parametric value. The microprocessor adjusts the current parametric value if the retrieved torque value is lower than the stored torque value.

Title: Stabilizing crosslinked polymer guars and modified guar derivatives
Inventor: HORNER DONALD NELSON
IPC: C09K8/08
Filed: 2005-08-04
Abstract: An aqueous, viscoelastic treating fluid gelled with a crosslinked guar or guar derivative is stabilized and improved with an effective amount of a glycol, such as ethylene glycol. These fluids are more stable in that viscosity is maintained, particularly at elevated temperatures. The additives may also increase viscosity to the point where less of a crosslinked guar or guar derivative gelling agent is required to maintain a given viscosity. These stabilized, enhanced, aqueous, viscoelastic fluids may be used as treatment fluids for subterranean hydrocarbon formations, such as in hydraulic fracturing.

Title: Systems and methods for decoding forward error correcting codes
Inventor: CONWAY ADRIAN EVANS
IPC: H03M13/00
Filed: 2006-05-11
Abstract: Systems and methods are disclosed that can improve the performance of decoders of forward error correcting codes by using the information contained in late packet arrivals to update (or recompute) the state of the decoder. The systems and methods of the disclosed embodiments are generally applicable to decoders that maintain state information in decoding successive bits or information frames. The systems and methods disclosed herein can improve the performance (i.e., the bit error rate) of the decoder since the recomputed state is exactly the state that the decoder would have had if the information contained in the late packet had originally arrived on time and been decoded in a usual manner. In effect, the updating of the decoder state following a late packet arrival terminates the propagation in time of the effect of the late packet erasure on the state of the decoder.
