Abstract: A device operable as a transducer is provided for use in which the device is mountable on a tow cable which in operation extends underwater substantially throughout the length thereof. The device comprises a head mass encompassing the tow cable wherein the head mass reacts to a wave-like strumming configuration about an axis of the tow cable thereby causing the tow cable to be displaced in one direction, along the axis and then in an opposite direction such that a low frequency continuous sound wave radiates from the head mass.

Abstract: Systems and methods are provided for determining information about particle geometry are provided. As such, an ultrasonic transducer acts as both a transmitter and a receiver. The transducer insonifies a particle and scattered waves are then received by the transducer—now acting as a receiver. A small flat target moving relative to a stationary receiver will lead to the same radiated field as waves propagating through an equivalent moving aperture. Based on the Doppler distribution of the scattered or radiated waves resulting from relative motion between the particles and a receiver, the acoustic pressure field in the plane of the equivalent two-dimensional aperture can be inferred. The equivalent aperture geometry can be obtained from the inferred field. Hence, the particle geometry can be determined.

Abstract: The invention as disclosed is a system for real time detection of tsunami waves. A tsunami is considered a “shallow water wave”, having a large wavelength compared to the ocean depth. A tsunami can have wavelengths ranging from 100 to 500 km, and amplitudes up to 60 cm (i.e., a pressure signal of up to 1 psi). At least one telecommunications grade optical fiber cable fitted with repeaters spanning the length of an ocean, a laser and a signal processor are used to measure pressure signals over spatial cells as small as 0.5 meters in width based on Rayleigh scattering effects and employing optical time delay reflectometry. The tsunami pressure signals are extracted from the pressure signals generated by wind-generated water waves (having much shorter wavelengths) through signal processing to distinguish between the substantial differences in wavelength, period and propagation speed.

Abstract: An underwater RF signal propagation path is created by utilizing a plurality of individual RF transceivers such as MEMS RF transceivers. Each MEMS RF transceiver has a predetermined buoyancy. A stream of the RF transceivers are released to form a line of RF transceivers underwater such that the individual RF transceivers have an RF transmission and reception distance greater than the distance between the RF transceivers whereby an RF signal can be repeatedly retransmitted down the line of RF transceivers.

Abstract: A sonar dome having an acoustic array housed therein. A plurality of bubbles are generated within the fluid inside the sonar dome. The generated bubbles are of an amount and size to reduce the speed of sound within the sonar dome fluid. Reduction of the speed of sound within the sonar dome fluid effectively increases the aperture of the acoustic array. The bubbles can be generated from a gas source or electrolytically. Typically, each individual bubble is less than 0.01 mm in diameter to reduce bubble velocity in the fluid.

Abstract: A method is provided for estimating the size of an object from a region of a fluid medium when that object is emitting acoustic radiation of known wavelength λ on its own or as the result of being interrogated by acoustic pulses that reflect from the object. The acoustic radiation is monitored using a line array of N acoustic receivers such that N signals indicative of the acoustic radiation are generated. M time series summations are formed using the N signals. Each of the M time series summations is formed using a unique time delay predicated on a corresponding unique estimated speed of propagation of the acoustic radiation where M estimated speeds of propagation are defined. For an object in the region having a diameter D on the order of λ, the M values will vary as a function of the M estimated speeds of propagation with the resulting distribution of the M values being indicative of diameter D.

Abstract: An acoustic array deployment system and a method are provided. An optical fiber acoustic array has a first end coupled to a projectile housed onboard an underwater vehicle. A second end of the array is coupled to the underwater vehicle. The acoustic array is stored on a spool while the projectile is housed onboard the underwater vehicle. The projectile is launched from onboard the underwater vehicle in a gravitationally downward direction that is not aligned with the underwater vehicle's direction of travel. As a result, the acoustic array is paid out from the spool as the projectile is launched and then sinks. By establishing the line array's broadside beam in a direction that is away from the vehicle and approximately perpendicular to the vehicle's direction of travel, the relative angular difference between the underwater vehicle and target can be used to guide the vehicle towards the target.

Abstract: An exercise apparatus for providing resistance to a motion of a user. The apparatus is provided with a bar having a pair of buoyancy chambers which causes the bar to float. A user may exercise by submersing the apparatus in a body of water against a buoyant force provided by the chambers. An anchoring system for both the user and the apparatus is provided to secure a position thereof in the body of water. In addition, the chambers may be inflated by a pressurized gas canister contained within the bar. The buoyancy chambers are retained between collars and circumferential journals on the bar. Pivotally openable clasps engage the journals. Cylindrical retainers are positioned over the clasps to prevent the clasps from opening, thus retaining the buoyancy chambers on the bar.
