Abstract

A method for calibrating an acoustic calibration tank providing the tanks with reference hydrophones positioned along the tank. The tank is filled with a fluid at a known temperature and pressure. A calibrated reverse hydrophone is positioned in the tank, opposite one of the reference hydrophones. A known acoustic wave is created in the tank using the calibrated reverse hydrophone and the opposite reference hydrophone output is measured. Free field voltage sensitivity is computed for the reference hydrophone. This gives the calibration factor for the reference hydrophone. The calibrated reverse hydrophone can be repositioned. An iterative process can be utilized for the other reference hydrophones, and other known pressures and temperatures.

Abstract

A method includes providing a set of deep learning neural networks where no pair of deep learning neural networks within the set of deep learning neural networks produces a semantically equivalent output by design. An input to the set of deep learning neural networks is provided, where responsive to the input, one or more of the deep learning neural networks produces an output. The output of the deep learning neural networks is input into a case-based reasoning (CBR) system. The CBR system generates an output responsive to the input received by the CBR system if the input received by the CBR system is known by the CBR system. The output of the CBR system is then determined to be a correct/incorrect output. One of the deep learning neural networks is trained on the correct output if the correct output is specific to the particular deep learning neural network.

Abstract

According to an exemplary embodiment of the inventive test method, heat is externally applied to an electrochemical “trigger” test cell via a heating element that receives electrical current from a power supply that is characterized by approximately the same impedance as the trigger test cell. For instance, the power supply and the trigger cell can be same or similar cells. The trigger test cell is proximate “propagation-vulnerable” test cells in a cell pack. Because of the impedance-matching between the power supply and the trigger test cell, the ensuing propagative behavior is at least substantially attributable to the short-circuit current failure of the trigger cell as brought about by the externally applied heat. The energy and/or power characterizing the power supply's current at least approximately equates to the energy and/or power characterizing the trigger test cell's short circuit current. Exemplary inventive testing is propitiously representative of real-world propagative failure events.

The snap-through buckling beam produces mechanical energy. The proof mass is attached to the snap-through buckling beam. The proof mass transfers mechanical energy to two piezoelectric transducers that convert the mechanical energy into electrical energy and produce an output signal. The ultra-low-power microcontroller unit converts the output signal into output data. The wireless transmitter transfers the output data to an external device. The power management unit provides the electrical energy to the ultra-low-power microcontroller unit and the wireless transmitter. The power storage unit is rechargeable, stores electrical energy from the two piezoelectric transducers, and non-replaceable. The autonomous sensor simultaneously harvests energy and measures vibrations in an external environment.

Abstract

Exemplary inventive practice replicatively tests the effects of cleaning processes applied to marine hulls coated with biofouling-control substances. A sample (e.g., antifouling-coated panel) is coupled with a trolley that is linearly moveable via trolley wheels upon two parallel tracks provided along the length of an open rectangular box-shaped tank, partially filled with natural or artificial seawater. The cleaning element (e.g., brush bristles) points vertically upward in a stationary position atop a motorized cleaning unit installed proximate the bottom of the tank. In accordance with the trolley's horizontal movement, and while the sample and cleaning element are immersed in seawater, the sample traverses the cleaning element in a contactual manner that mimics underwater cleaning dynamics for a hull surface. Using sensory data, seawater portions are evaluated to relate the cleaning instrumentation and operation to the nature and degree of biocides and chemicals that, concomitant the cleaning, are released into the seawater.

Abstract

A torque meter shaft that includes a hollow tube, a ring with ring tabs, the ring enveloping the hollow tube, a shaft with shaft tabs and a deformable section, the shaft disposed within the hollow tube such that the ring tabs and the shaft tabs correspond forming an inter-locking non-contact fit, and a first spline coupling and a second spline coupling. The first spline coupling communicates with an engine such that torque from the engine is transferred to the deformable section and elastically deforms when torque is applied to the first spline coupling and the shaft tabs change radial position relative to the position of the ring tabs such that relative change in torque can be measured, and when torque results in creating a shaft deformation that passes the material yield point, the ring tabs and shaft tabs contact each other, and the ring tabs are pushed back into a new position that compensates for the shaft deformation allowing the engine to maintain its full power capacity.

Abstract

Exemplary practice of the present invention provides a magnetostrictive actuator characterized by linear force output and uniform magnetic biasing. A center bias magnet combined with a flux transfer tube produces a uniform magnetic bias down the length of a magnetostrictive component. Depending on the inventive embodiment, the magnetostrictive component may include one magnetostrictive element or a pair of collinear magnetostrictive elements. A center bias magnet, in combination with a flux transfer tube, drives magnetic flux through the magnetostrictive component (e.g., a series of magnetostrictive rods) in opposite directions, while surrounding drive coils apply flux in the same direction through the magnetostrictive component. The net response is substantially linear with respect to the drive coil current. The flux transfer tube applies distributed magnetic flux to the magnetostrictive component at a rate that ensures uniform magnetic flux density down the length of the magnetostrictive component.

Abstract

A thermocouple (TC) protection gauge may guard TCs from flying debris and fragments in an explosive environment or demanding commercial environments. The gauge may contain multiple co-located TCs. By using the protection gauge, the survivability of the TCs is significantly increased and allows for a longer time frame of data collection. Temperature data is acquired from multiple TCs that are experiencing approximately the same gas temperature and gas velocity. The temperature data may be used to reconstruct the real gas temperature of a dynamic event. Each of the TCs has a different diameter and therefore has a different time resolved temperature trace. The individual temperature traces may be used to extrapolate the real gas temperature using, for example, a reconstruction algorithm.

Abstract

A self-supervised machine-learning system identifies whether an intermittent signal is present. The system includes a receiver, an encoding neural network, a decoding neural network, and a gating neural network. The receiver detects radiation and from the detected radiation generates a sampled sequence including sampled values describing the intermittent signal and noise. The encoding neural network is trained to compress each window over the sampled sequence into a respective context vector having a fixed dimension less than an incoming dimension of the window. The decoding neural network is trained to decompress the respective context vector for each window into an interim sequence describing the intermittent signal while suppressing the noise. The gating neural network is trained to produce a confidence sequence from a sigmoidal output based on the interim sequence. Despite the noise, the confidence sequence identifies whether the intermittent signal is present in each sampled value in the sampled sequence.

Abstract

Methods and systems are provided for schedule deconfliction to enhance cooperation among heterogeneous teams of autonomous agents in situations where communication is severely limited. A dynamic scheduling framework, referred to herein as the Generous Agent Algorithm (GAA), organically deconflicts redundant service tasks as agents from distinct teams come into conflict and discover one another. Individual agents within a localized area can communicate their schedules to one another. Using the GAA, the agents propose modified schedules, vacating their most costly task from their schedules, while simultaneously augmenting their schedules with another agent's vacated task. The action taken by an agent does not increase an agent's makespan beyond the time set by that agent's team. Thus, the methods and systems, ensure that schedule alterations are done without degrading a team's global makespan.

Abstract

A secure communication network includes interconnected switches including a source switch, a destination switch, and an intermediate switch. Packets are transferred over the secure communication network from a start node to an end node. The source switch replaces an original payload of each packet with an encrypted payload that combines the original payload and a respective random pad for the packet. The source switch then discards the respective random pad. The source and intermediate switches forward each packet toward the destination switch. The destination switch replaces the encrypted payload of each packet with a decrypted payload, which combines the encrypted payload and the respective random pad so as to match the original payload, discards the respective random pad, and transmits the packet with the decrypted payload to the end node. A controller sends the respective random pad for each packet to the source and destination switches via secure management links.

Abstract

A wideband antenna transmits and/or receives electromagnetic radiation. The wideband antenna includes a feedline, a first dielectric layer, a via, a driven patch, a second dielectric layer, and a parasitic patch. The feedline couples a radiofrequency signal and an element of the wideband antenna. The first dielectric layer is between the feedline and the driven patch. The via couples the radiofrequency signal of the feedline through the first dielectric layer. The driven patch couples between the electromagnetic radiation and the radiofrequency signal of the via. The second dielectric layer has a low dielectric constant of less than 1.3. The parasitic patch is electrically isolated from the driven patch by the second dielectric layer between the driven patch and the parasitic patch. The parasitic patch electromagnetically couples with the driven patch and the electromagnetic radiation to produce a wideband frequency response of the wideband antenna.

Abstract

Provided is a firearm cartridge chamber with a relief feature that traps a portion of a cartridge case within the cartridge chamber when fired. The relief feature causes the cartridge case to deform within the chamber, wherein it optionally separates into a forward section and a rearward section. The deformed case remains trapped after firing, preventing extraction of the fired case and the chambering or firing of any subsequent cartridges, thereby causing a firearm malfunction. The cartridge chamber can distinguish between higher and lower pressure cartridges by allowing for normal firing and function with blank training ammunition while also facilitating localized deformation of the cartridge case when firing standard ammunition that includes one or more projectiles. The inventive chamber prevents more than one higher pressure round from firing while allowing lower pressure or training rounds to fire without limitation, which aids in enhanced safety during training exercises.

Abstract

A lift based acoustic source is towable in an undersea environment by a towing vessel. A controller provides a combined lift control signal and an acoustic source signal. A control cable is joined between the towing vessel and a towed depressor having an active lift control system. The combined signal is used to control the towed depressor active lift control system. The towed depressor lift fluctuates in response to the source signal to generate the undersea acoustic signal. A hydrophone or hydrophone array can be provided for measuring the generated acoustic signal for feedback and monitoring.

Abstract

A method is provided to measure a modulus of complex sensitivity of hydrophone data channels using a quasi-diffuse sound field. In the method, a radiation pattern representing shallow water sources directs to a location as a direct acoustic path and sound reflects to the location from the water bottom as a reflected acoustic path. At least one hydrophone receives the sounds at the location as acoustic signals with an acoustic intensity being the sound intensities along the acoustic paths. The sound intensity at the hydrophones also relates to a zenith angle and a bottom intensity reflection coefficient. The modulus of the frequency dependent sensitivity of the hydrophone is computed from measurements of the voltage output and voltages of reference hydrophones with the sound intensity as factor and with uncertainty reduced by averaging hydrophone sensitivities.

Abstract

According to exemplary practice of the present invention, a probe laser beam characterized by a Stokes luminescence wavelength is trained upon a thermally insulated medium; the Stokes luminescence is measured upon conclusion of the probe laser impingement of the medium. Following this first Stokes luminescence measurement, a pump laser beam characterized by an anti-Stokes luminescence wavelength is trained upon the medium; the Stokes luminescence is measured upon conclusion of the pump laser impingement of the medium. Each laser has a blocking device associated therewith. A computer is implemented to transmit control signals to open and close the two blocking devices in alternating fashion so that only one laser beam at a time is aimed at the medium. The computer is also implemented to process the measurement signals to determine heating versus cooling. If the luminescence intensity following the pump laser impingement exceeds the luminescence intensity following the probe laser impingement, then the medium is being cooled.

Abstract

A minimally invasive method for attaching to a surface is provided. The method utilizes an attachment apparatus for non-penetrating mechanical attachment of components to a target surface. The apparatus includes a cartridge assembly and mounting assembly. Actuation of the cartridge assembly causes first and second exothermic reactants located between outer casing and the inner casing to come into contact and cause an exothermic reaction. This reaction liquefies a bonding material between the cartridge assembly and mounting assembly, allowing it to flow around the mounting assembly and onto a target surface creating a seal. Vacuum pressure will bind the mounting assembly to a target surface.

Provided herein are projectiles for use in a propellant driven disrupter device, and associated methods, to neutralize an explosive target. The projectile may comprise a friction reducing container at least partially filled with one or more fluids, fluid mixtures, particles, and other components to provide one or more desired fluid properties to achieve a desired one or more jet parameters upon target impact. The fluid(s) in the container are referred to as highly efficient energy transfer (HEET) fluids do to the improved fluid jet action on target compared to conventional water projectiles. The projectiles and disruptor can be more precisely individually tailored to the target, thereby increasing the likelihood of successful disablement and decreasing the likelihood of inadvertent and uncontrolled explosion.

A second material of the second layer scintillates a second stream of photons for each of the beta particles, but passes the first stream of photons for each alpha particle. The photomultiplier amplifies the first and second streams of photons for the alpha and beta particles into an electrical signal. The electrical signal includes a respective pulse for each of the alpha and beta particles. From the electrical signal, the analyzer determines a respective energy of each of the alpha and/or beta particles from a shape of the respective pulse for each of the alpha and beta particles.

Abstract

An amputation system includes a cutting element having a cutting blade traversing a V-shape. The V-shape has a vertex and an angle in a range of 90-120°. A rod, rigidly coupled to the cutting element, has its longitudinal axis aligned with the vertex so it bisects the angle of the V-shape. A barrel having a bore receives at least a portion of the rod therein wherein the rod's outboard end resides in the bore. An energetic energy source, positioned in the bore adjacent to the rod's outboard end, generates a pressure force that is incident on the rod's outboard end. The pressure force is one that peaks within 0.5 milliseconds to propel the rod from the bore at a velocity in a range of 300 to 1000 feet per second.
