摘要： A connector assembly includes a first and a second releasable and mateable connector. Each connector includes a front assembly composed of a manifold and a plurality of optical stems. Each manifold includes a plurality of inserts and a plurality of spherical seal assemblies. Each seal assembly is composed of a spherical ball, a ball dowel pin, and a ball actuator pin having a cam. Each spherical ball is configured to rotate about an axis defined by the two pins when the actuator pin cam traverses a groove fabricated in one of a plurality of guide rails disposed in the first connector. When the plurality of seal assemblies are in an open configuration, the optical stems of the first connector may slide through the inserts of the first connector, through the seals, and mate with the optical stems of the second connector within the inserts of the second connector.

摘要： An acoustic transducer and method of generating acoustic transmit and receive beams is disclosed. The system includes a plurality of transducer elements arranged to form an array, where the elements are electrically connected into groups which operate at the same electrical phase, where the phases of adjacent groups of elements differ by between about 50 and 70 degrees and a beamforming circuit where the transmit and receive signals are operated with appropriate phase shifts to maintain the between about 50 and 70 degrees phase difference between adjacent groups. The resulting transducer generates transmit and receive beams that are nominally inclined less than about 30 degrees from a planar normal axis of the array.

摘要： A near-field hydrophone is disclosed. The near-field hydrophone includes a housing, a piezoelectric element configured to produce an analog signal in response to an acoustic signal generated by the release of compressed air into water, an analog circuit coupled to the piezoelectric element, wherein the analog circuit is configured to receive the analog signal and to produce a conditioned analog signal, an analog-to-digital converter configured to receive the conditioned analog signal and to produce a digitized form of the conditioned analog signal, and a processor coupled to a memory circuit and to the analog-to-digital converter, wherein the processor is configured to control the operation of the analog-to-digital converter and to provide a digitized serial communication output corresponding to the digitized form of the conditioned analog signal. The piezoelectric element, the analog circuit, the analog-to-digital converter, the processor, and the memory circuit are located within the housing.

摘要： A submersible sound system may include a housing, an end piece, an elastic membrane, an end cap affixed to the elastic membrane, and a subwoofer speaker system disposed within the housing and supported by a speaker support. A bubble sound source may be defined by the speaker support, the speaker diaphragm, an anterior end of the housing, the elastic membrane, and the end cap. The housing, end piece, and a posterior surface of the speaker support may form a sealed enclosure. The sound system may include a tuning pipe disposed between the sealed enclosure and the bubble sound source. A Helmholtz resonator may be disposed anteriorly of the speaker system. Multiple sound system may be assembled to form a cluster. The cluster may be defined by the vertices of regular polyhedron. The sound systems may be controlled to maintain the speaker systems within acceptable thermal limits.

摘要： In one aspect, an acoustic full-duplex communication system includes a transmitter array having at least two transmitters. The transmitters are positioned along an axis of maximum transmission and are separated by about half of a wavelength of a transmission frequency band. The transmitters transmit waveforms of opposing polarity that mutually interfere in a plane orthogonal to the transmission axis. The system includes a receiver array having at least one receiver in the orthogonal plane. In a second aspect, an underwater acoustic full-duplex communication system includes a transmitter and two receivers. The receivers are symmetrically positioned about an axis, separated by about half of a wavelength of a transmission frequency band, and equidistant from the transmitter. The receivers are connected in opposing polarity. Either aspect may include an adaptive filter to improve cancellation of transmitter originated near field transmissions received by the one or more receivers.

摘要： A hybrid energy harvesting system for powering underwater vehicles having at least one thermal engine, at least one of a solar or a wave energy harvester, and a battery which stores electric energy produced by the harvesters. The energy harvesters keep the battery charged and thereby expand an underwater vehicle's operational areas to high latitudes and shallow water. Multiple thermal engines employing different phase-change materials can be used to expand the vehicle's working temperature range and thus allow it to operate over a larger area. An electric motor powered by the battery and a pump driven by the motor can be used to pump hydraulic fluid between the accumulators and external bladders of the thermal engines to cause the vehicle to descend and ascend when the thermal gradient to which the vehicle is subjected is insufficient.

摘要： An apparatus and a method for a trace oxygen sensor is configured with a floating cathode that has a capability to detect part-per-billion (ppb) level or less of oxygen in a gas background. An electrolyte reservoir can supply electrolyte when electrolyte level is low. An electrolyte reservoir may be connected to the main cell along with a protection electrode.

摘要： A variable inductor includes a three-limbed core first section having an inductor winding wound about a medial limb. An air gap is disposed in the medial limb. The inductor includes a second section having a control limb in which a first end of the control limb is connected to a first outer limb of the three-limbed core, and a second end of the control limb is connected to a second outer limb of the three-limbed core. A control winding is wound about the control limb. The inductor may be used in a control circuit to control a power signal driving a transducer. The inductor may be controlled by a signal derived from a comparison of a voltage phase of a power signal to the transducer and a phase of the current traversing the transducer. A system may include the control circuit, including the variable inductor, and the transducer.
