摘要： A sensor configured to sense when a force is applied to a surface includes a capacitive structure having a first conductive layer, a dielectric layer, and a second conductive layer. The dielectric layer is overlain on the first conductive layer and the second conductive layer is overlain on the dielectric layer. A glass superstrate has a first side and a second side, with the first side overlain on the second conductive layer. The force is applied to the second side of the glass superstrate. The force results from an object attached to the second side of the glass superstrate. The force causes capacitance changes between the first and second conductive layers. The force can be compressive or tensile, depending on whether the object is attached by magnet or adhesive.

摘要： Embodiments are directed to sensors that detect objects attached to a vehicle. The sensor includes a layered capacitive structure. The sensors utilize a deformable dielectric layer sandwiched between two conductive layers. The layered capacitive structure measures capacitance changes caused by an applied force to the uppermost layer of the capacitive structure.

摘要： A radio frequency (RF) test hat. The RF test hat may comprise: a cylinder having forward and aft ends, end cap, arm and strap assembly, first and second absorber materials, a receiving antenna, and lens. The end cap may couple to the forward end of the cylinder. The arm and strap assembly may hingedly couple to the aft end of the cylinder and may be configured to mount the RF test hat onto a pod or transmitting antenna. The first absorber material may be located within the forward end of the cylinder. The second absorber material may be located near the aft end of the cylinder. The receiving antenna, which may be disposed within the first absorber material, may measure the intensity of a beam of electromagnetic radiation. The lens, which may be located within the middle portion of the cylinder, may spread the beam across a larger surface area of the first absorber material.

摘要： An RF test hat. The RF test hat may comprise: a body having a substantially rectangular portion with open forward and aft ends, an end cap, arm and strap assembly, absorber material, a receiving antenna, lens, and upper and lower mesh screens. The end cap may couple to the open forward end of the body. The arm and strap assembly may hingedly couple to the open aft end of the body. The absorber material may be within the end cap. The receiving antenna may be disposed within the first absorber material and may measure the intensity of a beam of electromagnetic radiation. The lens may be located within the middle portion of the body and may spread the beam across a larger surface area of the absorber material. The upper and lower mesh screens may be disposed between the end cap and lens and may comprise openings that are substantially hexagonal in shape.

摘要： A system for augmenting 360-degree aspect monostatic radar cross section of an aircraft. The system may comprise a pair of pods mountable on opposing wing tips of an aircraft and each having a pod housing with an elongate body tapering forwardly to a nose and rearwardly to a tail. Each pod may comprise a forward SDL disposed within the nose, a rear SDL disposed within the tail, and a pair of mid-body SDLs disposed within a mid-section of the pod housing. The SDLs may be arranged within the pods to reflect radiation and provide coverage around the aircraft over a region of about 360 azimuth degrees. Each SDL may comprise radar absorbing material located on an interior reflective surface, and portions of the elongate bodies may be constructed of radome material. The SDLs may be Luneburg lens having diameters of at least approximately 8-inches.

摘要： The embodiments are directed to methods of initiating insensitive explosive formulations. The disclosed methods include positioning a donor explosive pellet adjacent to an insensitive acceptor explosive pellet having a plurality of relative percent theoretical maximum density (TMD) zones. The insensitive acceptor explosive pellet is adjacent to an insensitive explosive fill. Upon donor explosive pellet initiation, the donor explosive pellet provides a shock stimulus to the insensitive acceptor explosive pellet, which initiates the insensitive acceptor explosive pellet, causing a detonation wave to be driven through the plurality of relative percent TMD zones and into the insensitive explosive fill.

摘要： A brine electrolysis system for producing pressurized chlorine and hydrogen gases. In its basic configuration, the brine electrolysis system may comprise: two liquid storage tanks for storing two liquid reactants; a tank having two interior spaces separated by a diaphragm for receiving the liquid reactants; two pumps for regulating the flow of the liquid reactants from the liquid storage tanks to the interior spaces of the tank, two open-bottom cylinders for storing and dispensing two gases; an electrolysis stack assembly for converting the liquid reactants into two gases; and two submersible pumps for pumping each liquid reactant into an electrolysis stack assembly. Each open-bottom cylinder may comprise a float sensor for determining the amount of fluid entering its cylindrical space. The system may further comprise controllers for regulating ionic concentrations within the two interior spaces. Dispense lines and valves may be utilized to release the gases.

摘要： The invention generally relates to novel poly-substituted cis stilbenes, their synthesis, their purification, and their use in thermoset resins. These novel cis stilbenes give rise to thermoset resins with greatly improved processing characteristics such as lower melting temperature and lower viscosity; resulting in polymers and composites having greatly improved thermal stability.
