摘要： A wireless power transmission and communication network that provides efficient interrogation and powering of sensors for use on undersea vehicles. The present invention employs a wave-guide that allows the propagation of electromagnetic waves through a dielectric material that covers the exterior of an undersea vehicle's hull. Embedded within the dielectric material is an N dimensional array of Micro Electronic Mechanical Systems sensing devices coupled with radio frequency (RF) decoders and transceivers, and strips of conductive metal tape. Electromagnetic waves such as microwaves propagate through the dielectric material both powering the sensor network and addressing and interrogating individual sensing devices. The sensing devices take readings and then format and transmit the data results back across the wave-guide where they are received and processed by a digital processor within the hull of the undersea vehicle.

摘要： A system and method are provided to supply power to and to communicate with an array of remote devices. The remote devices can be acoustic sensors or types of remote devices. In a preferred embodiment, the system includes a microwave source/signal demodulator that supplies wireless power and provides data interrogation signals to the sensors. The microwave transmission line is of a stripline construction. The source/demodulator radiates power to the sensor transceivers and receives data from the sensors. The source/demodulator can transmit sequential interrogation signals to activate address-selectable sensors. The source/demodulator may also decode received signals returning from the sensors. The stripline may be attached to a vessel's hull beneath a hull treatment layer and the sensors mounted on the surface of the hull treatment.

摘要： A reinforced foam core acoustic baffle includes a pressure-release polystne foam core, upper and lower steel reinforcing plates, a plurality of steel reinforcing rods, and a high-density foam skirt. The reinforcing plates are bonded to the upper and lower surfaces of the foam core, and the reinforcing rods are received through the core and are secured between the reinforcing plates so as to maintain the plates in spaced relation. The high-density foam skirt comprises a plurality of high-density foam panels which are bonded to the side surfaces of the foam core so as to overlap the upper and lower reinforcing plates. The foam panels are bonded with a watertight epoxy adhesive that forms a watertight seal with the reinforcing plates, and the foam panels further prevent the pressure-release foam from being crushed inwardly at the sides.

摘要： A remotely controllable signal device, such as a buoy which may be used as target for gunfire training includes platform, a radio receiver, a decoding device, and one or more visual location signaling devices. The platform is floatable in the case of a buoy. The visual location signaling devices provide a visual indication of the location of the device. The visual location signaling devices include smoke generating devices such as marine smoke canisters, and a light such as a strobe light. The light can be mounted on a short tower for higher visibility. The decoding device can be a dual-tone multiple frequency decoder, and can include a switching device which selectively activates one of a number of visual location signaling devices located on the platform. The radio receiver may be a UHF AM receiver. The platform can also include a Global Positioning System transceiver device to assist in tracking the platform in the open ocean. As another option, the platform can include a sonar pinger to allow acoustic tracking of the impacts of shells when implemented as a buoy on instrumented hydrophone tracking ranges.

摘要： The present invention is an electrical circuit for a sensor designed to detect external magnetic fields. The circuit is composed of a stable voltage reference source, connected to a low frequency amplifier where the operating point of the amplifier depends on the voltage reference source that is biased for maximum allowable voltage swings of the amplifier. A GMI fiber is connected to the low frequency amplifier and to a crystal oscillator that generates a square wave excitation signal with which to excite the GMI fiber. A decoupling network connected to the amplifier allows stable excitation of the GMI fiber by separating the direct current paths of the amplifier from the excitation signal. When the GMI fiber is excited by the square wave signal the GMI fiber impedance varies with impressed magnetic fields, which in turn varies the output voltage of the amplifier.

摘要： A preamplifier and pre-emphasis network is provided having a differential plifier exhibiting common mode noise rejection. The preamplifier is particularly suited for use with a double-sided sensor element and it includes a double-sided, balanced calibration circuit. First and second variable gain buffers are joined to the differential amplifier for preventing current noise degradation at the differential amplifier inputs. A pre-emphasis network is further provided in conjunction with the variable gain buffers for providing balanced differential gain of the sensor element signal. Further elements of the invention provide for high and low pass filtering, and differential buffering of the output signal.

摘要： A wireless hydrophone system includes a hydrophone joined to a preamplifier. A serial A/D converter receives the amplified hydrophone signal and provides a serial digital output representative of the signal. The A/D converter is joined to a processor which provides a start signal and a clock signal to the A/D converter. A digital transmitter is also controlled by the processor. The transmitter receives the serial digital output from the A/D converter for wireless transmission over an antenna. The system can also include logic for allowing the processor to provide an extended sync signal for transmission. The extended sync signal can alert a receiver to an initial transmission. The system can be incorporated in a hull treatment for positioning on a vessel's hull.

摘要： The balanced, bi-directional calibration circuit of the present invention joined to a sensor and a differential preamplifier. The sensor has two outputs which are received by the differential preamplifier such that common-mode line noise is rejected. The calibration circuit includes a broadband signal generator which provides the calibration signal. The calibration circuit also includes a switching network that allows the calibration signal to be switched to either of the two sensor outputs or isolated from the sensor and preamplifier. A dual-state switching control signal is applied via a single control wire to the switching network to select which preamplifier input receives the calibration signal. The calibration signal generator control line is electrically isolated from the preamplifier by an opto-isolator. The electrical balance of the bi-directional calibration circuit and electrical isolation of the calibration signal generator preserve the common-mode noise rejection of the differential preamplifier.
