Abstract: Methods and systems are disclosed for discovery of knowledge, interest and experience of individuals indicated by measured psychophysiologic response (e.g., electroencephalograph) to sensible stimuli (e.g., images). Stimuli are selected to explore targeted topics described in various levels of detail and sub-categories organized as hierarchal trees. The degree of psychophysiologic response to stimuli associated with sub-categories of topics in the hierarchal tree guides selection of additional stimuli to systematically explore hierarchal tree nodes, levels and branches to discover the extent of knowledge, interest or experience related to the targeted topic.

Abstract: Techniques are disclosed for detecting knowledge based on brainwave response to external stimulation. A subject can be exposed to stimuli and brainwave responses indicating a p-300 signal can be detected. Further stimuli or sequences of stimuli can be selected be presented to the subject based on the category correlated with the stimuli that indicate a p-300 response.

Abstract: A plurality of sound emitters mounted on a vehicle having a configurable phase of emission and configured such that they focus the beam pattern in a selected direction.

Abstract: A phase-change device for use in a volume of fluid, comprising a pressure vessel; a displacement cylinder; a displacement piston; a drive cylinder containing a phase-change material; a drive piston; and a gas spring. As the device sinks and experiences cooler fluid temperatures, the phase change material reduces in volume, causing the drive cylinder to move relative to the drive piston and thereby exert an outward force on the displacement piston. The displacement piston is pulled away from the displacement cylinder, increasing the overall displacement of the device. The increase in displacement increases the buoyancy of the device, thereby causing the device to rise in the fluid.

Abstract: A watercraft comprising a plurality of linearly ordered, connected segments that are configured to enable the connected segments to articulate relative to each other in at least one degree of freedom. The watercraft harvests mechanical energy from ambient waves by means of the articulation of the segments, and converts the mechanical energy into electrical energy that powers a propulsion mechanism.

Abstract: An optical geophone or hydrophone for detecting seismic vibrational energy comprising a laser material, which generates a lasing frequency signal, the frequency of which varies in accordance with vibrational energy incident upon the laser material, a light source occurring at an excitation frequency for providing excitation energy incident upon the laser material, so that the laser material emits light at the lasing frequency modulated by the vibrational energy and a fiber optic cable for transmitting the excitation frequency light to the laser material and receiving the frequency modulated lasing frequency for transmission to a receiver. The laser material comprises a first face and a second face, the first face being parallel to the second face. The first face is coated so that it passes substantially all of the lasing frequency light and reflects substantially all of the excitation frequency light.

Abstract: This present invention provides an array formed by a continous line array of piezoelectric film with discrete points of increased sensitivity to sense and measure acoustic signals. The configuration provided by the present invention simultaneously provides the advantages and attributes of both the continuous line array and the multi-element discrete array. The line array and the multi-element array are designed to enhance or cancel specific frequency bands of signal noise and to enhance beam forming of the array. The piezoelectric array can be extended and shaped into two-dimensional and three-dimensional hydrophone arrays. The present invention comprises a continuous line array formed by a single piece of piezoelectric film with one or more points of enhanced sensitivity to alter the beam pattern or spectral sensitivity of the array. The electrical output of the entire array may be observed with one set of connectors, one positive and one negative lead.

Abstract: An apparatus and system for integrating acoustic pods within marine seismic streamers. The integrated acoustic pod eliminates the attachment and detachment of acoustic pods from the streamer exterior surface when the seismic streamers are deployed into and retrieved from the water. Control electronics are integrated within the streamer interior and receive electric power from a streamer electrical conductors and receive control signals from a streamer control wire. The control electronic components can be integrated within the streamer interior or within modules connecting each streamer section. Acoustic transducer elements can extend through the connector module or can be attached to the connector module exterior. The acoustic transducer elements can be oriented to steer transmission of acoustic energy into the water, such as in a horizontal azimuth, and to permit correction of the steering direction.

Abstract: A marine vessel having backup power storage in the event of primary power source failure. The invention applies to different marine vessels and is particularly suited to vessels used in marine seismic operations. A rotating mass energy storage provides stored energy which can be distributed to the vessel following primary power source failure. A pulsed generator charges the energy storage means, and the pulsed generator can comprise a homopolar generator or a compensated pulsed alternator.
