Abstract: The invention as disclosed is of a coaxial transducer that uses lead zirconate titanate ceramic or other suitable material as an isolator between the conductors in a coaxial cable to transmit acoustic power at useful levels. The lead zirconate titanate ceramic is diced into thin disks and placed in between spacers made of much stronger insulating material. The coaxial cable is then integrated into a conventional double-armored steel tow cable with a typical diameter of 1″. This provides substantial longitudinal strength and provides crushing resistance to the lead zirconate titanate ceramic when the cable is being deployed or retrieved over a sheave under tension.

Abstract: A system and method are provided for launching and recovering an unmanned, water-borne vehicle (UWBV) from a mother ship. The UWBV mimics the behavior of dolphins and is positioned ahead of the ship in preparation for bow riding. The UWBV uses a guidance system to position and keep in the bow wave. A high-frequency (HF) sonar transceiver array aboard the ship computes and sends course corrections to maintain the UWBV within the bow wave. The frequency range of the HF array can be 100 kHz or higher due to the short distance between the ship and the UWBV. Accordingly, the HF array can have a small aperture allowing for accurate bearing resolution. Course corrections can be sent on a near-continuous basis such that changes in thrust and rudder angle can be minimized to allow for accurate control of the UWBV.

Abstract: A method for determining the direction of an incoming signal is provided in which each of a plurality of receivers arranged in a linear array is sampled in sequence to simulate a single receiver moving along an aperture defined by the linear array at a simulated speed. This generates a simulated time series data from which a simulated Doppler shift in the incident angle is measured. The simulated Doppler shift is used to determine the incident angle between the incident signal and the linear array of receivers. By adjusting the simulated speed to eliminate artifacts in the power spectral density of the data obtained from the receivers, the incident angle can be obtain from the expression of the simulated Doppler shift.

Abstract: A tow cable in which the temperature of the cable is measurable by the use of multiplexing capability intrinsic to optical fibers in which the optical fibers are positioned at the center of the tow cable and wound as part of two layers of surrounding strength wires. The optical fibers of the two layers intersect a vector extending radially from the optical fiber at the center to an outer surface of the tow cable. Light signals emitted from a multiplexer to positions along the optical fibers, in which the positions intersect the vector, return light signals from the positions to provide measurements that in conjunction with a data processor further provide temperature measurement of the outer boundary of the tow cable.

Abstract: A safety device for reducing the likelihood of superheating a liquid includes a transducer disposed on a support surface proximate to a placed container containing a liquid. The transducer generates a vibrational force in the container and onto the liquid that creates nucleation within the liquid. The nucleation allows the liquid to boil, thus preventing the liquid from becoming superheated.

Abstract: A system for preventing overflow from a tank being filled. An open-ended elongated adapted for fixture to a tank extends from an opening of the tank and proximate to a bottom of the tank. A nozzle connectable to a source of pressurized liquid has an open end extension extending through the opening into the elongated tube. The nozzle creates broadband acoustic signals inside of the elongated tube during filling. A microphone mounted on the nozzle near the open end extension senses resonant frequency signals of the acoustic signals and generates representative signals. A module processes the representative signals and generates a closing signal when the representative signals represent a critical resonant frequency. A shut-off valve between the fuel source and the nozzle is responsive to the closing signal.

Abstract: A system and method is provided for determining the temperature to which a structure is subjected. An optical fiber having at least one pair of fiber sensors is attached to the structure. The fiber sensors comprise Bragg gratings and each is configured to have a particular coefficient of thermal expansion and be responsive to a particular wavelength. A broadband spectrum of light is launched into the optical fiber. The light returning from the fiber sensors is detected. The temperature to which the structure is subjected is then determined based on the difference in strain response of the fiber sensors as a result of the effects of temperature upon the fiber sensors. Coatings of different materials may be applied over the optical fiber to provide the fiber sensors with differing coefficients of thermal expansion.

Abstract: The present invention is a method of coating a substrate. First, a layer of liquid polymeric coating having a pigment and a solvent is applied to the substrate. An ultrasonic acoustic source is then provided and operated at a frequency of from about above 40 kHz to provide an acoustic pressure field and an it acoustic pressure of above 190 dB and directing the main lobe of the acoustic pressure field toward the layer of liquid polymeric coating. This acoustic pressure field reduces the gradient in and smoothes any uneven surface features in the liquid polymeric coating.

At least one acoustic transducer is coupled to the fluid flow in a region that is susceptible to the formation of cavitation bubbles. The transducer (or transducers) applies an acoustic field to the fluid flow in order to raise the cavitation threshold pressure of the fluid flow above the total local pressure including the pressure drop induced by the fluid flow and the pressure due to the acoustic field.
