摘要： An improved corrosion-resistant magnetic influence minesweeping cable is provided. The cable produces a magnetic field that simulates a ship's magnetic signature as the ship passes through the sea. It has an outer anode conductor made of titanium-clad copper with mixed metal oxide at its aft end, an outer cathode conductor made of nickel-clad copper at its forward end, an inner conductor made of aluminum that runs the length of the cable, and a steel core strength member that also runs the length of the cable. The outer anode conductor is in electrical contact with the inner conductor. The outer cathode conductor is insulated from the inner conductor. The outer cathode conductor and the inner conductor can be connected to an electrical power source onboard a towing vessel.

摘要： A system for thermal transient imaging of an object includes a radiation source configured to irradiate the object with radiation in accordance with an excitation profile. An imaging device includes an array of detector pixels and is configured to detect thermal radiation from a surface of the object. A processor is configured to obtain a series of frames of thermal image data of the surface acquired by the imaging device over time when the object is irradiated by the radiation source. The processor is further configured to process, using the excitation profile, the series of frames of thermal image data to transform the thermal image data to an equivalent wave field representation that represents a series of depth-resolved virtual images of the object.

摘要： A DC superconductor quantum interference device (i.e. DC SQUID) is used in a flux-locked loop as a sensitive detector of magnetic flux. Prior art devices of this sort had a transfer function which was frequency-limited by the transfer function of impedance matching circuitry which is used to connect the DC SQUID with the first preamplifier, which amplifies the DC SQUID signal before it is applied to a detector circuit. The present invention corrects this frequency limitation by creating a compensating circuit having a transfer function which is the inverse of that of the impedance matching circuitry, and inserting it in the system after the first preamplifier and before the detector circuit.

摘要： A type of Superconducting Quantum Interference Device (SQUID) requires that relatively large, circular, toroidally wound wire coils within a first cavity of a superconducting canister should be inductively coupled to a relatively small SQUID created as an annular ring plus Josephson junctions upon a substrate within a second cavity of the superconducting canister. The required inductive coupling is through a dielectric filled cavity called a coupling cavity which is conical in the shape of a dunce's cap. The conically shaped coupling cavity within the superconducting canister minimizes the parasitic stray inductance which is coupled to the SQUID, and thusly improves the noise performance of the SQUID.

摘要： A superconducting quantum interference device (SQUID) is direct current biased through physical connections asymmetric to, and preferably maximally asymmetric to, the two Josephson junctions. The asymmetric SQUID so created is, responsively to such physical asymmetry, biased for operation in the linear region of the input magnetic flux/output (voltage or current) device response curve. A resistance of specified value is connected in parallel, or shunt, to the parasitic bridge capacitance of the asymmetric SQUID in order to minimize hysteresis. Two asymmetric SQUIDS of opposite asymmetry are serially connected as a push-pull linear amplifier stage which exhibits zero output (voltage or current) at zero input magnetic flux, and which is specifiable in parameters of construction so as to exhibit optimum linearity of response about such point. Plural successive such linear amplifier stages are connected by an LC filter, which filter is lowpass to the Josephson oscillation frequency, in order to form a linear amplifier entirely with the cyrogenic environment and with a bandwidth of the order to D.C. to 10.sup.9 Hertz.

摘要： A connector anchors as outer conductor onto a cable and connects the outer conductor to the cable's inner conductor without exposing the inner conductor to the ambient environment. The connector includes a longitudinally split cylinder having a thicker center wall and a pair of flanking walls that wrap around a notched section of the cable and contact the inner conductor. An inner ring with multiple recessed interior circumferential grooves wraps around and overlaps the split cylinder so that the grooves will emboss and grip the cable's jacket without piercing the jacket when swaged. The outer conductor is placed over the inner ring. An outer ring anchors the outer conductor to the inner ring when swaged.

摘要： A system for forming an image of an object in a turbid medium comprises a light source for producing a coherent light beam of a selected frequency that is divided by a beamsplitter into a reference beam directed along a first optical path and a signal beam directed along a second optical path where the object to be imaged is located. The signal beam impinges upon the object and reflects back toward the beamsplitter. The reference beam is modulated to shift its frequency. A mirror reflects the reference beam back toward the beamsplitter for combination with the signal beam to produce an output optical signal. A photodetector receives the output optical signal from the beamsplitter and produces an electrical signal having a frequency related to shifts in frequency between the reference beam and the signal beam and having an amplitude proportional to the image intensity. A heterodyne detector connected to the photodetector produces a beat signal when the first and second optical paths have matching lengths so that the location of the point on the object where the signal beam reflected can be determined. By scanning the signal beam across the object, the system determines locations of a number of points on the object sufficient to form its image.
