Abstract: Seismic interpretation includes obtaining a seismic volume of a subterranean formation of a field. Through the seismic volume based on a similarity criterion of seismic values in the set of seismic traces, an estimated horizon is generated based on a selected seed while maintaining tracking data tracking the generating of the estimated horizon. A first selection of a selected point in the estimated horizon is received, and, from the tracking data, an ancestral path from the selected point to the selected seed is extracted. A subset of the set of seismic traces is selected based on the subset comprising points along the ancestral path, and displayed, within a graphic window on a physical display, the subset of the set of seismic traces.

Abstract: A method of detecting tissue oedema in a subject. The method includes determining a measured impedance for first and second body segments. An index indicative of a ratio of the extra-cellular to intra-cellular fluid is then calculated for each body segment, with these being used to determine an index ratio based on the index for the first and second body segments. The index ratio can in turn be used to determine the presence, absence or degree of tissue oedema, for example by comparing the index ratio to a reference or previously determined index ratios.

Abstract: In some embodiments, apparatus and systems, as well as methods, may operate to enable moving a drill string through a borehole while acquiring data generated by a plurality of receiver sub-arrays included in a drill string. The sub-arrays may be separated by one or more sources of sonic energy, as well as by a non-aliased receiver spacing distance, a distance associated with a selected aperture of investigation, or a distance associated with a formation slowness. The sonic energy may be received by the sub-arrays at a plurality of stations. Data may be collected at a telemetry receiver.

Abstract: A method and apparatus for the non-invasive measurement of cardiac function. A signal is applied between a pair of electrodes on a patient. The signal delivers a constant alternating current at multiple simultaneous frequencies. A second pair of electrodes measures a voltage signal. The impedance at each frequency is obtained by demodulating the current signal and the voltage signal using techniques such as Fast Fourier Transform (FFT). The FFT gives a phase and amplitude which is converted to an impedance value. The impedance values are fitted to a theoretical frequency dependent impedance locus and the locus is extrapolated to obtain a value at zero frequency. The steps are repeated to obtain a time-varying plot of impedance and measures of cardiac function are calculated from the time-varying plot.

Applying the plurality of signal thresholds to the acoustic borehole signal to determine a corresponding plurality of peak amplitudes and signal travel times for selected ones of the plurality of signal thresholds may also be included.

Abstract: A seismic acquisition system comprising a remote-controlled buoy for conducting seismic acquisition operations. The buoy comprises an operating system for operating a seismic wave production device on the buoy, a placement system, a communications system, and dynamic position locating system. The seismic acquisition system also comprises a remote control system for controlling the buoy systems. The seismic acquisition system also comprises receivers for receiving the seismic wave and generating a data signal indicative of the received seismic wave. The seismic acquisition system operates by controlling the placement system with the remote control system to position the buoy and then controlling the operating system with the remote control system to produce a seismic wave from the seismic wave production device. The receivers then receive the seismic wave and generate a data signal indicative of the seismic wave.
