There is provided herein a system and method of acquiring, processing, and imaging transient Controlled Source ElectroMagnetic (t-CSEM) data in ways that are similar to those used for seismic data. In particular, the instant invention exploits the time-distance characteristics of t-CSEM data to permit the design and execution of t-CSEM surveys for optimal subsequent processing and imaging.

A method of analyzing results from an underwater controlled source electromagnetic (CSEM) survey of an area that is thought or known to contain a subterranean hydrocarbon reservoir is described. The method is based on a wavefield extrapolation of narrow-band electromagnetic field data obtained from pairs of source and receiver locations. The data comprise a plurality of discrete frequencies between 0.01 Hz and 60 Hz. The wavefield extrapolation is performed for each of these discrete frequencies to provide distributions of electromagnetic scattering coefficient as a function of position and depth beneath the survey area. These distributions may then be combined to provide a displayable image of electromagnetic scattering coefficient. The method is able to quickly provide a displayable image that is readily interpretable.

3D music visualization process employing a novel method of real-time reconfigurable control of 3D geometry and texture, employing blended control combinations of software oscillators, computer keyboard and mouse, audio spectrum, control recordings and MIDI protocol. The method includes a programmable visual attack, decay, sustain and release (V-ADSR) transfer function applicable to all degrees of freedom of 3D output parameters, enhancing even binary control inputs with continuous and aesthetic spatio-temporal symmetries of behavior. A “Scene Nodes Graph” for authoring content acts as a hierarchical, object-oriented graphical interpreter for defining 3D models and their textures, as well as flexibly defining how the control source blend(s) are connected or “Routed” to those objects. An “Auto-Builder” simplifies Scene construction by auto-inserting and auto-routing Scene Objects. The Scene Nodes Graph also includes means for real-time modification of the control scheme structure itself, and supports direct real-time keyboard / mouse adjustment to all parameters of all input control sources and all output objects. Dynamic control schemes are also supported such as control sources modifying the Routing and parameters of other control sources. Auto-scene-creator feature allows automatic scene creation by exploiting the maximum threshold of visualizer set of variables to create a nearly infinite set of scenes. A Realtime-Network-Updater feature allows multiple local and / or remote users to simultaneously co-create scenes in real-time and effect the changes in a networked community environment where in universal variables are interactively updated in real-time thus enabling scene co-creation in a global environment. In terms of the human subjective perception, the method creates, enhances and amplifies multiple forms of both passive and interactive synesthesia. The method utilizes transfer functions providing multiple forms of applied symmetry in the control feedback process yielding an increased level of perceived visual harmony and beauty. The method enables a substantially increased number of both passive and human-interactive interpenetrating control / feedback processes that may be simultaneously employed within the same audio-visual perceptual space, while maintaining distinct recognition of each, and reducing the threshold of human ergonomic effort required to distinguish them even when so coexistent. Taken together, these novel features of the invention can be employed (by means of considered Scene content construction) to realize an increased density of “orthogonal features” in cybernetic multimedia content. This furthermore increases the maximum number of human players who can simultaneously participate in shared interactive music visualization content while each still retaining relatively clear perception of their own control / feedback parameters.

The more the wind-power generator sets are simulated, the more evidently the efficiency is improved, simulation step-length can be increased on the premise of guaranteeing accuracy, and simulation efficiency is improved greatly.

Features within an integrated-circuit memory chip enables scrambling or randomization of data stored in an array of nonvolatile memory cells. In one embodiment, randomization within each page helps to control source loading errors during sensing and floating gate to floating gate coupling among neighboring cells.

In another embodiment, randomization is implemented both within a page and between pages. The scrambling or randomization may be predetermined, or code generated pseudo randomization or user driven randomization in different embodiments. These features are accomplished within the limited resource and budget of the integrated-circuit memory chip.

Systems and methods as described for providing visual telepresence to an operator of a remotely controlled robot. The robot includes both video cameras and pose sensors. The system can also comprise a head-tracking sensor to monitor the orientation of the operator's head. These signals can be used to aim the video cameras. The controller receives both the video signals and the pose sensor signals from the robot, and optionally receives head-tracking signals from the head-tracking sensor. The controller stitches together the various video signals to form a composite video signal that maps to a robot view. The controller renders an image to a display from that portion of the composite video signal that maps to an operator view. The relationship of the operator view to the robot view is varied according to the signals from the pose sensors and the head-tracking sensor.

The polarization direction of a signal is rotated by a polarization controller so as to be orthogonal to the main axis of a polarizer. A control pulse generator generates control pulses from control source with a wavelength which is different from the wavelength of the signal. The signal and the control pulse are input to a nonlinear optical fiber. In the nonlinear optical fiber, the signal, during the time period in which the signal and the control pulse coincide, has its polarization direction rotated by cross phase modulation, and is amplified by optical parametric amplification. The signal, during the time period in which the signal and the control pulse coincide, passes through the polarizer.

Method for efficient inversion of controlled-source electromagnetic survey data to obtain a resistivity model of the subsurface of the survey area. The method extracts the dimensions and location of sub-surface structures as they may be revealed by existing seismic or other available high resolution survey data from the subsurface area (33). This structure geometry information is used to construct a discretization (grid, or mesh) for the inversion computation (34) that is different from the mesh used for the forward modeling calculations (32) in that (a) it has fewer and hence larger cells; and (b) the cells honor the assumed structural information. The inversion need only extract resistivity information (35), the geometry of the resistive structures being specified by the inversion mesh.

Method for determining time-dependent changes [73] in the earth vertical and horizontal electrical resistivity and fluid saturations from offshore electromagnetic survey measurements. The method requires both online and offline data, which should include at least one electromagnetic field component sensitive at least predominantly to vertical resistivity and another component sensitive at least predominately to horizontal resistivity [62]. Using a horizontal electric dipole source, online Ez and offline Hz measurements are preferred. For a horizontal magnetic dipole source, online H2 and offline E2 data are preferred. Magnetotelluric data may be substituted for controlled source data sensitive at least predominantly to horizontal resistivity. Maxwell's equations are solved by forward modeling [64,65] or by inversion [66,67], using resistivity models of the subsurface that are either isotropic contrast, and [64,66] or anisotropic [65,67]. Fluid saturation is determined from the vertical and horizontal resistivities using empirical relations or rock physics models [70].

The inventive system and method advantageously enable superior preserved storage, preservation, and management of selective dispensation of beverages (e.g., wine), by storing the beverages in a pressurized environment to ensure that the stored beverage does not come into contact with air, and then by selectively dispensing a portion of the stored beverage, in accordance with a desired dispensing regime (which may be configured and controlled locally, remotely, and / or via a computerized system), by utilizing a controlled source of pressure force to apply a sufficient pressure to the pressurized environment to expel the desired volume of the beverage in a pressurized stream directed to a remote dispensing / pouring interface (for example located in a desired area of a bar, restaurant, or other hospitality establishment) through a liquid delivery system. In at least one embodiment thereof, the system and method of the present invention are configured for use with compressible wine-in-bag (“WinB”) product containers placed into at least one pressurized chamber (serving as the pressurized environment) and interfaced with a liquid delivery system connected one or more dispensing components.

A method of analysing electromagnetic survey data from an area of seafloor (6) that is thought or known to contain a conductive or resistive body, such as a subterranean hydrocarbon reservoir (12), is described. The method includes providing electric field data and magnetic field data, for example magnetic flux density, obtained by at least one receiver (25) from a horizontal electric dipole (HED) transmitter (22) and determining a vertical gradient in the electric field data. The vertical gradient in the electric field data and the magnetic field data are then combined to generate combined response data. The combined response data is compared with background data specific to the area being surveyed to obtain difference data sensitive to the presence of a subterranean hydrocarbon reservoir. Because the combined response data are relatively insensitive to the transverse electric (TE) mode component of the transmitted signal, the method allows hydrocarbon reservoirs to be detected in shallow water where the TE mode component interacting with the air would otherwise dominate. Furthermore, because there is no mixing between the TE and transverse magnetic (TM) modes in the combined response data, data from all possible transmitter and receiver orientations may be used. The background data may be provided by magneto-telluric surveying, controlled source electromagnetic surveying or from direct geophysical measurement.

Apparatus and method for estimating the 3D orientation angles for remotely deployed devices with flexible arms such as dipole antennas of receivers used in marine controlled-source electromagnetic surveys to explore for hydrocarbons. Acoustic transponders or transducers, or other positioning sensors such as attitude sensors or strain-sensitive fiber optic cables are placed on each electrode arm of the receiver. Acoustic sensors (101) on the receiver frame (94) work in conjunction with the positioning sensor(s) (101) on the electrode arms (92) to provide accurate 3D spatial position of the receiver electrodes (93) relative to the receiver frame. Alternatively, sonar transducers mounted on the frame are used to image the electrode arms, which image can be enhanced by fixing reflectors to the arms. An attitude sensor is mounted on the receiver frame, enabling conversion of the relative electrode positions to an earth reference frame.
