Abstract: K data signals are transmitted over a shared spectrum in a code division access communication system. A combined signal is received and sampled over the shared spectrum (48). The combined signal has the K transmitted data signals (48). A combined channel response matrix is produced (49) using the codes and impulse responses of the K transmitted data signals. A block column of a combined channel correlation matrix is determined using the combined channel response matrix (50). Each block entry of the block column is a K by K  matrix (51). At each frequency point k, a K by K matrix is determined by taking the Fourier transform of the block entries of the block column (52). An inverse of a K by K matrix is multiplied to a result of the Fourier transform (52). Alternately, forward substitution (53) and backward substitution (54) can be used to solve the system. An inverse Fourier transform is used to recover the data from the K data signals (55).

Inventor: BALDAUFF JOHN J
IPC: E21B47/10
Filed: 2001-09-19
Abstract: A novel method, system and tool for performing formation and well evaluation while drilling are disclosed. These inventions determine the properties of a particular formation (F) within a reservoir as the reservoir is being intersected during well construction. In one form of the invention, the formation evaluation is made using a direct measurement of the formation's ability to flow fluids. The flow potential of a reservoir during underbalanced well construction is determined as the well is being constructed. The methods produce an understanding of the volumes and types of the fluids such as oil, gas, and/or water, that can be produced out of discrete sections of a formation within a reservoir as the reservoir is intersected. The trajectory and path of the wellbore through the reservoir are modified to intersect formation having more desirable permeability and productivity to decrease the time to market of the hydrocarbon reserves within a reservoir without the time delay inherent when conventional formation evaluation techniques are applied.  A downhole flow measurement instrument (27) is used to obtain actual flow ratios. The instrument is integrated into a near-bit stabilizer (12) and can be used for early kick and benign "breathing" fractures detection in the open hole wellbore.

Title: Method and device for minimizing oil consumption in a gas turbine engine
Inventor: LIU XIAOLIU
IPC: F01D25/18
Filed: 2002-11-07
Abstract: A method of minimizing oil consumption in a gas turbine engine, by avoiding reliance on air intake into the engine oil circuit for bearing chamber oil sealing purposes. The engine has an oil circuit with at least one bearing supporting at least one engine shaft at a support point along a shaft axis, at least one bearing chamber enveloping each bearing and maintaining a volume of oil with an oil-air interface in communication with a volume of air, and an oil circulation system in flow communication with each bearing chamber for supplying a flow of oil to a bearing chamber inlet and for evacuating spent oil from an outlet of the bearing chamber. The method involves sealing each bearing chamber with a hydropad seal between the shaft and bearing chamber.  The hydropad seal having an annular ring mounted to the shaft and an annular pad mounted to the chamber, each having abutting seal surfaces. During engine operation the ring rotates to cast oil radially outwardly from the shaft axis toward the outer periphery of the bearing chamber under centrifugal force. Oil is then collected from the outer periphery of the bearing chamber and directed to the bearing chamber outlet.
