  • Patent number: 10047731
    Abstract: Systems and methods for improving plasma propellant ablation/sublimation based systems are provided. One set of embodiments provides systems and methods for reducing carbon charring during plasma system (e.g., a plasma coating application system) propellant (e.g., a carbon-fluorine polymer) ablation and increasing heat transfer, ablation, and plasma thrust from plasma systems. In particular, one embodiment can include using a nano or micro-sized magnetic or electromagnetic field responsive material as particulates or microcapsules that are intermixed with polytetrafluoroethylene (e.g., TeflonĀ®) nano-fibers, and using resulting fiber composites as the propellant material. Embodiments can include improved plasma system, e.g., pulsed plasma thrusters, plasma torches, plasma coating systems, etc, as well as nozzle improvements such as embodiments with magnetic structures disposed in relation to the nozzle. Alternative embodiments also include recovery and reuse systems.

  • Patent number: 9417286
    Abstract: A system and method for image enhancement associated with scan generators is provided. For example, a source stimulates a device under test (DUT) at electrical interconnects. An internal clock of the DUT is synchronized with the scan rate of the source to reduce the noise of the output signal and enhance a resultant image. A phase adjustment is effected to further reduce the noise in the signal. The synchronization and the phase adjustment seek to ensure that the data is collected at uniform times relative to the reference signal and thereby reduce the noise introduced into the system, by such offsets. Post-scan processing increases the signal-to-noise ratio through averaging techniques. Using a pixel overlay algorithm the averaged data is transformed into a 2-D array and the image of the DUT reconstructed.

  • Patent number: 8907225
    Abstract: A method and an apparatus for mitigating electrical failures caused by intrusive structures. Such structures can be tin whiskers forming on electrical circuits. In an illustrative embodiment, nano-capsules are filled with some type of insulative and adhesive fluid that is adapted to bind to and coat an intrusive structure, e.g., a whisker, making the whisker electrically inactive and thereby reducing the electrical faults that can be caused by the whisker. In another illustrative embodiment, randomly oriented nano-fibers having an elastic modulus higher than tin or any other whisker material is used to arrest a growth or movement of a whisker and further reduce a likelihood that a whisker can cause an electrical fault.
