摘要： 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.

摘要： A method for isolating vibrations from a source on a structure includes modeling the structure as a beam having a portion for isolation. A sensor is positioned proximate to the source, and at least one actuator is positioned on the structure between the source and the portion for isolation. A controller receives signals from the sensor and calculates vibrational inputs for each actuator that will isolate the structure portion. Driving signals are provided to each actuator by the controller in response to the calculated vibrational inputs, and each actuator is vibrated accordingly, isolating the structure portion from the source. This method can be implemented in multiple configurations to isolate the structure portion.

摘要： A safety system and method of use is provided for a tow cable handling system. In use, the cable is from a winch and onto a sheave where a cable tension surge is transmitted to a meter and onto a software element. The software of a controller determines torque needed from a motor to increase winch speed to unreel cable to relieve the surge but not too much that the cable will unreel off the winch. Once the surge concludes, the motor reverses and decreases speed of the winch. If the tension surge is transient, then the motor can increase the winch speed and then slow down the winch before the cable completely unreels. The sheave is suspended by a spring and a dashpot for an over-damped response to increase the time for the winch to speed up to an acceptable speed.

摘要： A neutrally buoyant underwater vehicle is provided in which a length of the vehicle is up to one tenth the length of a predetermined acoustic wavelength. The vehicle includes an inertial navigation system with an accelerometer capable of measuring velocity in a multi-axis direction. The navigation system is operationally connected to a hydrophone which measures acoustic energy of the wavelength arriving at the underwater vehicle. A processor gathers the data from the accelerometer and the hydrophone to convert the data into usable units. The operation of the vehicle-based components is similar to a vector sensor for frequencies of 250 Hz or lower.

摘要： An acoustic projector is provided with an enclosure having a semi-permeable membrane on one side. High salinity liquid is injected at the enclosure to increase osmotic pressure. Valves thereafter allow free flooding between the enclosure and surrounding seawater to equalize the pressure. Transient pressure in the enclosure generates a pressure pulse that propagates from the semi-permeable membrane. The timing of the injection by salt jets and the free-flooding valves enables a repeatable acoustic pulse at low frequencies and a determinable upper frequency. If the acoustic projector is mounted to be conformal to the hull of a ship; the acoustic projector includes a free-flowing region on one side of a semi-permeable membrane and valves. When the valves are opened; the other side of the membrane is free-flooded. Salt jets inject high salinity liquid into an enclosure to increase pressure with the result of an acoustic pressure pulse.

摘要： A method is provided for transmitting a plurality of narrowband signals in estimating a Doppler shift of a target object. The method includes simultaneously transmitting at least two narrowband signals from a source and receiving incident signals at a receiver. Multiple narrowband signals can be sent simultaneously and in combination with broadband signals from a source. The incident signals are filtered and processed to determine range and Doppler shift of the target.

摘要： A method of use for parametric sonar is provided that utilizes an acoustic beam formed at a difference frequency generated by non-linear interaction of acoustic energy of primary frequencies. At least three primary frequencies are transmitted from a frequency source by amplifiers and acoustic projectors of the sonar. The non-linear interaction of the primary frequencies produces at least three difference frequencies. The difference frequencies are received by a receiver array. Increased interaction increases efficiency linearly with the number of primary frequencies used. The increased bandwidth resulting from the use of multiple center frequencies can also produce signal processing gains and signal-to-signal ratio is also improved, especially at the lower difference frequencies.

摘要： A well conductor strain monitoring system is provided which includes a plurality of fiber optic Bragg grating sensors written onto a single optical fiber. Cable strands are wound around the optical fiber to form an armored cable protecting the fiber. The armored cable is further integrated into a strength cable to provide robustness. This strength cable is then wrapped around the conductor under tension and anchored at both ends. The cable is wound at a prescribed angle so as to have multiple wraps around the conductor. Once tensioned, the cable remains stationary against the conductor and holds a position. The strain gages are spaced along the optical fiber, such that the strain gages are oriented 90 degrees apart when the cable is wrapped about the conductor. This orientation supports the estimation of bending in any direction.
