| 41 | RECONSTRUCTION OF NONLINEAR WAVE PROPAGATION | US12629739 | 2009-12-02 | US20100165348A1 | 2010-07-01 | Jason W. Fleischer; Christopher Barsi; Wenjie Wan |
| Disclosed are systems and methods for characterizing a nonlinear propagation environment by numerically propagating a measured output waveform resulting from a known input waveform. The numerical propagation reconstructs the input waveform, and in the process, the nonlinear environment is characterized. In certain embodiments, knowledge of the characterized nonlinear environment facilitates determination of an unknown input based on a measured output. Similarly, knowledge of the characterized nonlinear environment also facilitates formation of a desired output based on a configurable input. In both situations, the input thus characterized and the output thus obtained include features that would normally be lost in linear propagations. Such features can include evanescent waves and peripheral waves, such that an image thus obtained are inherently wide-angle, farfield form of microscopy. | ||||||

| 53 | Coupler for electrical waveguides and mechanical waveguides | US786538 | 1991-11-01 | US5220296A | 1993-06-15 | Andreas von Flotow; Nesbitt Hagood; Tomas Valis |
| A system for coupling energy between electrical and mechanical waves includes a mechanical waveguide for propagating a mechanical wave having a mechanical wavelength at a given frequency, and an electromechanical energy converter for coupling energy between electrical and mechanical waves attached to a portion of the waveguide and capable of propagating an electrical wave having an electrical wavelength substantially equal to the mechanical wavelength at the given frequency. The portion has a length, measured in units of coupled wavelength, which is selected on the basis of the reciprocal of the coupling strength of the electromechanical converter and a selected amount of wave energy to be coupled. The function is based primarily on desired efficiency and may also be an odd integer multiple of the coupling strength reciprocal, preferably one. Piezoelectric elements are the preferred electromechanical energy conversion elements. This system is applicable to damping of structural waves, transferring structural waves from one mechanical waveguide- to another, and for creating a linear motor. | ||||||
| 54 | Method for mixing audio subliminal recordings | US440244 | 1989-11-22 | US5170381A | 1992-12-08 | Eldon Taylor; James R. Woodhams |
| Audio subliminal recordings are made in which in addition to using a primary carrier, such as music, two audio channels are used to deliver subliminal messages to the brain. On one channel, accessing the left brain hemisphere, the message delivered is meaningfully spoken, forward-masked, permissive affirmations delivered in a round-robin manner by a male voice, a female voice and a child's voice. On the other channel, accessing the right brain, directive messages, in the same voices, are recorded in backward-masked (or meta-contrast). The three voices are recording in round-robin fashion with full echo reverberation. The audio tracks are mixed using a special processor which converts sound frequencies to electrical impulses and tracks the subliminal message to synchronize the subliminal message in stereo with the primary carrier. The processor maintains constant gain differential between the primary carrier and the subliminal verbiage and, with the subliminal verbiage being recorded with round-robin, full echo reverberation, ensures that none of a message is lost. The primary carrier should be continuous music without breaks or great differences in movements. | ||||||

| 57 | Method and apparatus for converting tube waves to body waves for seismic exploration | US496089 | 1990-03-15 | US4993001A | 1991-02-12 | Graham A. Winbow; Mark S. Ramsey; J. David Fox |
| Method and apparatus for converting tube waves into body waves downhole for seismic exploration are disclosed, comprising a rotary valve tube wave source for producing swept frequency tube waves that are injected into a tubing or wellbore.

The tube wave converter comprises an elongate body that preferably substantially fills the wellbore or tubing and has a preferred shape in order to convert efficiently the tube waves to body waves at the selected position downhole. | ||||||
| 58 | Fish behavior control system | US255145 | 1988-10-07 | US4932007A | 1990-06-05 | John Suomala |
| A device for modifying the behavior of fish, causing them to swim along a desired path, projects sequences of sound into the water, resulting in sound wave patterns which direct the fish along the desired path. The device includes a fish detector, which detects the monitors the activities of fish, an array of sound projectors and a controller. When fish are detected the controller generates sequences of signals which are applied to the projector array. The projectors project corresponding sounds into the water, producing the sound wave patterns. The detector monitors the activities of the fish and the controller, if necessary, adjusts the sound sequences until the fish are directed along the path. When the detector no longer detects any fish, the controller stops applying signals to the projector array, preventing approaching fish from habituating to the projected sounds. | ||||||
| 59 | Acoustic convective system | US172100 | 1988-03-23 | US4858717A | 1989-08-22 | Eugene H. Trinh; Judith L. Robey |
| A small and simple system is provided for cooling or heating a small component by flowing air or other fluid over it, which does not require any macroscopic moving parts. The system includes a transducer and reflector that are spaced apart with the component between them, and with the transducer being operated at a frequency resonant to the spacing between it and the reflector. The resulting standing wave pattern produces acoustic streaming which results in the circulating of air or other fluid in the environment across the component. The system is especially useful in the reduced gravity environment of outer space because of the absence of any buoyancy-induced convection there. | ||||||
| 60 | High temperature acoustic levitator | US526750 | 1983-08-26 | US4463606A | 1984-08-07 | Martin B. Barmatz |
| A system is described for acoustically levitating an object (12, FIG. 1) within a portion of a chamber (14) that is heated to a high temperature, while a driver (22) at the opposite end of the chamber is maintained at a relatively low temperature. The cold end of the chamber is constructed so it can be telescoped to vary the length (L.sub.1) of the cold end portion and therefore of the entire chamber, so that the chamber remains resonant to a normal mode frequency, and so that the pressure at the hot end of the chamber is maximized. The precise length of the chamber at any given time, is maintained at an optimum resonant length by a feedback loop. The feedback loop includes an acoustic pressure sensor (42) at the hot end of the chamber, which delivers its output to a control circuit (44), which controls a motor (36) that varies the length (L) of the chamber to a level where the sensed acoustic pressure is a maximum. | ||||||
