Title: Downhole cyclic pressure pulse generator and method for increasing the permeability of pay reservoir
Inventor: BARYKIN ALEXEY EVGENIEVICH
IPC: E21B43/263
Filed: 2007-05-30
Abstract: This invention relates to the oil and gas industry and to exploration and production of water resources, in particularly, for stimulation of fluid flow to the well, e.g., for higher oil production, productivity index, and recovery factor. The disclosed device and method can be used for higher permeability of the pay zone due to creation of a network of microcracks in the bottomhole formation zone and facilitates to increase the flow of oil, or other fluids, from the reservoir to the well. Generation of cyclic pressure pulses with varied amplitude and time parameters and proper localization of pulses in space through mechanism of convective combustion provides a "soft" impact upon the wellbore without risk of damage or formation consolidation; the said impact is achieved by using a device which is a downhole cyclic pressure generator operating by a consecutive combustion of layers of compositions having different combustion rates. The compositions are made on the basis of loose-paked solid fuel, solid oxidizer, and functional additive of a liquid hydrocarbon.

Title: Adjustable landing gear system
Inventor: WILSON PHILLIP K
IPC: B64C25/10
Filed: 2009-06-25
Abstract: A landing gear system includes a shock strut assembly and a linkage member coupled to an aircraft. Preferably, the shock strut assembly and linkage member are oriented or angled relative to one another in a non-parallel relationship. Actuation of the linkage member moves the shock strut from a de-hiked to a hiked configuration or vice-versa. In addition, the orientation of the linkage member relative to the shock strut assembly permits it to automatically move the shock strut assembly to the de-hiked position during retraction of the landing gear system and prevents the shock strut assembly from exceeding a desired length during retraction. The linkage member may take the form of a hydraulic actuator having a lower end portion coupled to an inner cylinder of the shock strut assembly and an upper end portion coupled to the aircraft aft of where the shock strut assembly is coupled to the aircraft.

Title: Sps receiver with adjustable linearity
Inventor: WANG KEVIN HSI-HUAI
IPC: G01S1/04
Filed: 2008-02-20
Abstract: A satellite positioning system (SPS) receiver that can provide good performance with low power consumption is described. The SPS receiver may be operated in one of multiple modes, which may be associated with different bias current settings for the SPS receiver. One of the modes may be selected based on output power level of a transmitter co-located with the SPS receiver. The bias current of an LNA, a mixer, and/or an LO generator within the SPS receiver may be set based on the selected mode. In one design, a first (e.g., lower power) mode may be selected for the SPS receiver if the transmitter output power level is below a switch point. A second (e.g., high linearity) mode may be selected if the transmitter output power level is above the switch point. The second mode is associated with more bias current for the SPS receiver than the first mode.
