摘要： An antenna includes a plurality of superconducting quantum interference device (SQUID) arrays on a chip, and a printed circuit board (PCB) formed with a cutout for receiving the chip. The PCB is formed with a set of coplanar transmission lines, and the chip is inserted into the cutout so that each said transmission line connects to a respective SQUID array. A cryogenic system can cool the chip to a temperature that causes a transition to superconductivity for the SQUID arrays. A thermal radome can be placed around the chip, the PCB and the cryogenic system to maintain the temperature. A DC bias can be applied to the SQUID arrays to facilitate RF detection. The SQUID array, chip and CPW transmission lines can cooperate to allow for both detection of said RF energy and conversion of said RF energy to a signal without requiring the use of a conductive antenna dish.

摘要： A method for connecting an integrated circuit (IC) to a printed circuit board (PCB) can include the steps of fixing the IC and the PCB to a dielectric substrate. A single wire bond can be used to bond the IC to the PCB, and a ground plane can be established for the PCB. To minimize inductance losses at high frequency operation, a ground plane defect can be intentionally established by forming at least one opening in the ground plane. The opening can be rectangular when viewed in top plan, although the number of openings formed and opening geometry can be chosen according to the desired operating frequency of the device. The defect can allow for single wire bonding of the IC to the PCB in a manner which allows for high frequency operation without requiring the integration of additional matching network components on the IC and PCB.

摘要： A dynamically balanced, tracked robot, which can switch between dynamically balanced (wheeled) operation and tracked operation, can include a body and at least one wheel rotatably mounted to the body. At least one strut can also be mounted to the body so that it extends therefrom, and an idler wheel can be fixed to the distal end of the strut. A track can be slipped over the wheel and that idler wheel, so that the track frictionally engages both the wheel and the idler wheel. The robot can have a defined vertical reference vector and a processor. The processor can have non-transitory written instructions that, when accomplished, cause the vertical reference vector to be parallel with a vector defined by the robot axis and the revised post-installation center of gravity, to continue to allow for dynamic balancing of the newly-tracked robot.

摘要： Systems and methods for wavelength optimization for underwater optical communication can include a plurality of n lasers having different wavelengths λi for i=1 to n, a beam splitter and a corner retro-reflector. The plurality of n lasers can simultaneously illuminate the beam splitter along a coincident axis. The plurality of n lasers can be selectively blocked so that only one laser wavelength λi at a time impinges on the beam splitter. A portion passes through the beam splitter to establish a reference signal, while the remainder is reflected off the corner retro-reflector. A portion of return illumination passes through the beam splitter to establish a return signal. The process can be repeated for each of n lasers for i=1 to n. The λi wavelength where the normalized signal-to-noise differential between the reference signal and return signal is the minimum can be the optimum communication wavelength.

摘要： A variable buoyancy buoy and method for deployment therefor can include a fixed buoyancy portion formed with a cavity and an enclosure. A pressure hull containing instrumentation can be place in the cavity, and a variable buoyancy portion that can be inserted into the enclosure. The fixed buoyancy portion can have a spar buoy configuration or a marker buoy configuration, and can further be formed with at least one opening to establish a path of fluid communication between the exterior of the buoy and the enclosure. The variable buoyancy portion can be a compressible bladder, or compressible foam, which can change form a maximum volume at the water surface to a minimum volume as the buoy descends towards stowage depth. The decrease in buoyancy facilitates retrieval of the buoy by an apparatus on the ocean floor.

摘要： A method for enhancing a microbial environment for a fuel cell can include the initial step of oxidizing the outer surface of the fuel cell anode to establishing reactive chemical functional groups. The anode surface can be oxidized by washing the anode with a solution of 4-carboxybenzene diazonium tetrafluoroborate, followed by washing with acetone, methanol and water. Once the anode surface has been oxidized, the methods can include the step of binding a surface graft matrix to the reactive chemical functional groups (the activated carboxyl groups on the anode surface). EDAC and sulfo-NHS can be used as a surface graft matrix, to bind to the activated carboxyl groups. A biological substance, such as a biological agent or biomolecule, can be chemically attached to the outer terminal reactive groups of the surface graft matrix. The result is a microbial fuel cell with increased power generation and durability properties.

摘要： An IED detection training device can include a barrel which can be adapted to receive a blank ammunition cartridge. A housing can be connected to the barrel, and a firing pin having a tab extending from the firing pin can be disposed in the housing. A spring can surround the firing pin, and a sleeve having a slot can surround the sleeve so that the firing pin tab is disposed in the sleeve slot. A lever can be pivotably attached to the housing so that the lever selectively engages the tab. A pull ring can also be pivotably attached to the housing, to selectively engage the lever. Pivoting of the pull ring can cause pivoting engagement of the lever and disengagement of the tab, which can further cause the spring to move the firing pin forward to strike the ammunition blank cartridge.

摘要： Class types of input signals having unknown class types are automatically classified using a neural network. The neural network learns features associated with a plurality of different observed signals having respective different known class types. The neural network then recognizes features of the input signals having unknown class types that at least partially match at least some of the features associated with the plurality of different observed signals having respective different known class types. The neural network determines probabilities that each of the input signals has each of the known class types based on strengths of the matches between the recognized features of the input signals and the features associated with plurality of different observed signals. The neural network classifies each of the input signals as having one of the respective different known class types based on a highest determined probability.

摘要： Methods for detection and identification of bacteria within a sample include the step of inserting a pair of electrodes into the sample. A first impedance across the electrodes is established with a first AC voltage source having a first frequency. A phage is introduced into the sample, and impedance fluctuations that are caused by ion release by the bacteria due to the phage introduction are measured. The use of impedance fluctuations instead of voltage fluctuations to detect and identify bacteria minimizes 1/f noise effects and increases system sensitivity. To further increase system sensitivity by eliminating thermal noise, a second impedance across the electrodes can be established using a second AC voltage source at a second frequency. Second impedance fluctuations are cross-correlated to the first impedance fluctuations, and the cross-correlation results are analyzed to determine whether or not bacteria are present in the sample based on phage electrical activity.
