Patent number: 8055446Abstract: A method for processing magnetotelluric data to identify subterranean deposits is provided for. The data comprise the amplitude of alternating magnetic or electrical fields recorded over time in at least two vector components at one or more locations in an area of interest. Amplitude pulses are identified in the data, wherein the pulses are time segments comprising an amplitude peak meeting defined threshold criteria in at least one vector component. The pulses are filtered at a set of predetermined frequencies to separate amplitude data at each frequency from the remainder of the amplitude data in the pulses. The frequencies correspond to subterranean depths over a range of interest. Differential impedances ?Z of the pulses at each frequency at each location are then statistically analyzed to determine a value correlated to the resistance of the earth at each frequency. The resistance values are indicative of the presence or absence of deposits at the corresponding subterranean depth at the location.Type: GrantFiled: October 11, 2006Date of Patent: November 8, 2011Inventor: Kent A.

Patent number: 6866098Abstract: System and methods for transmitting and receiving electromagnetic pulses through a geological formation. A preferably programmable transmitter having an all-digital portion in a preferred embodiment may be operated at frequencies below 1 MHz without loss of target resolution by transmitting and over sampling received long PN codes. A gated and stored portion of the received signal may be correlated with the PN code to determine distances of interfaces within the geological formation, such as the distance of a water interfaces from a wellbore. The received signal is oversampled preferably at rates such as five to fifty times as high as a carrier frequency. In one method of the invention, an oil well with multiple production zones may be kept in production by detecting an approaching water front in one of the production zones and shutting down that particular production zone thereby permitting the remaining production zones to continue operating.Type: GrantFiled: October 30, 2002Date of Patent: March 15, 2005Assignee: The United States of America as represented by the National Aeronautics and Space AdministrationInventors: G.

Patent number: 6650280Abstract: System and methods are disclosed for fluid measurements which may be utilized to determine mass flow rates such as instantaneous mass flow of a fluid stream. In a preferred embodiment, the present invention may be utilized to compare an input mass flow to an output mass flow of a drilling fluid circulation stream. In one embodiment, a fluid flow rate is determined by utilizing a microwave detector in combination with an acoustic sensor. The acoustic signal is utilized to eliminate 2&pgr; phase ambiguities in a reflected microwave signal. In another embodiment, a fluid flow rate may be determined by detecting a phase shift of an acoustic signal across two different predetermined transmission paths. A fluid density may be determined by detecting a calibrated phase shift of an acoustic signal through the fluid. In another embodiment, a second acoustic signal may be transmitted through the fluid to define a particular 2&pgr; phase range which defines the phase shift.Type: GrantFiled: September 14, 2001Date of Patent: November 18, 2003Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: G.

Patent number: 6559645Abstract: Transceiver and methods are included that are especially suitable for detecting metallic materials, such as metallic mines, within an environment. The transceiver includes a digital waveform generator used to transmit a signal into the environment and a receiver that produces a digital received signal. A tracking module preferably compares an in-phase and quadrature transmitted signal with an in-phase and quadrature received signal to produce a spectral transfer function of the magnetic transceiver over a selected range of frequencies. The transceiver initially preferably creates a reference transfer function which is then stored in a memory. Subsequently measured transfer functions will vary depending on the presence of metal in the environment which was not in the environment when the reference transfer function was determined. The system may be utilized in the presence of other antennas, metal, and electronics which may comprise a plastic mine detector for detecting plastic mines.Type: GrantFiled: October 30, 2001Date of Patent: May 6, 2003Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: G.

Patent number: 6529443Abstract: A two-conductor bidirectional digital telemetry interface between a seismic sensor acquisition/conversion module and a seismic data collection module. The data collection module is configured as a master electronics device and the sensor acquisition/conversion module is configured as a slave electronics device in the telemetry system. The master device provides power to the slave device over the two conductors. The master device transmits portions of commands to the slave device at a first time and the slave device transmits portions of a digital seismic data packet to the master at a different second time in a fixed-duration frame. The frames are transmitted at regular intervals. The outbound commands and inbound data are encoded by block codes. A phase-locked loop in the slave is locked to a master clock in the master by deriving a clock and a sync point from the block-coded commands it receives from the master.Type: GrantFiled: January 10, 2001Date of Patent: March 4, 2003Assignee: Input/Output, Inc.Inventors: John C.

Patent number: 4762994Abstract: A compact optical scanner includes a base unit and a scan unit. The base unit includes an optical source such as a laser and an optical path directing a beam emitted by the laser to a scan mirror which is located in and supported by the scan unit. As the scan mirror rotates, the optical beam is reflected back to the base unit from which it is emitted as a beam scanning to and fro in a scan plane. The scan unit is supported by reference to the base unit such that the oscillation axis of the scan mirror is substantially and preferably parallel to the scan plane.Type: GrantFiled: November 10, 1986Date of Patent: August 9, 1988Assignee: IBM Corp.Inventors: Kent A.

Patent number: 4692877Abstract: A pel timing clock compensates for the non-linear displacement profile of a resonant galvanometerscanner. A pel time counter is loaded with a count value and outputs a clock pulse after expiration of a delay serial determined by the count value. Each time the clock pulse is produced the pel time counter is reloaded. The various count values are accessed from a memory which is addressed by an address counter whose contents are also altered each time the clock pulse is produced. The memory stores a sequence of count values which, when used to load the pel time counter, produces the desired sequence of clock pulses to compensate for the non-linear displacement profile of the scanner.Type: GrantFiled: June 27, 1986Date of Patent: September 8, 1987Assignee: IBM CorporationInventors: Kent A. Byerly, Marvin E. Feldhacker, Duane E. Grant
