20100022929 | Snap Lock Assisted Mechanical Joint - A compact close contour mechanical joint that uses a snap ring, a transfer gear partially press-fit into a brake wheel, a distal bar having integral gear teeth that engage the exposed portion of the transfer gear, a second bar with a T-shaped proximal end, a handle disengaging an unlocking pin to separates gear teeth that allows incremental distal bar movement, and a two-axis arrangement for distal bar rotation. Instead of using a spring biasing member, the mechanical joint uses a gear ratio reduction that provides a smaller stop increment, less travel, enhanced joint strength, less stress on gear teeth, and less force required to unlock it than prior close contour joints. Although it is contemplated for use of the mechanical joint to be primarily in orthotic, any application for which the mechanical joint's compact configuration would provide some assistance or technical advantage is considered to be within its scope. | 01-28-2010 |

20130053762 | METHOD AND APPARATUS FOR COLD PLASMA TREATMENT OF INTERNAL ORGANS - Chronic sinusitis is treated by the application of cold plasma or plasma-activated species to the infected mucosal surfaces through use of an endoscope having a steerable end which may be projected into the sinus cavities through the nasal cavity. The cold plasma is generated at either the distal end of the endoscope with a power source by application of a power, or at the distal end by gas and electrical connections extending through the endoscope. The cold plasma or plasma-activated species act to destroy bacterial cells but not eukaryotic cells. | 02-28-2013 |

20140264048 | NEUTRON RADIATION SENSOR - Embodiments utilize high energy particles generated by nuclear reactions involving neutron radiation and neutron-sensitive materials to generate and maintain an electric potential gradient between an electrode and a region separated from the electrode by an electric insulator. System and methods contemplated by the invention thereby enable passive detection of neutrons without an externally applied electric potential bias by maintaining a charge accumulation facilitated by nuclear reactions involving neutrons. The charge accumulation produces an electric potential gradient within an electric insulator that separates the charge accumulation from an exterior region. | 09-18-2014 |
20140315347 | Scalable Multi-Role Surface-Wave Plasma Generator - Systems and methods are described herein for generating surface-wave plasmas capable of simultaneously achieving high density with low temperature and planar scalability. A key feature of the invention is reduced damage to objects in contact with the plasma due to the lack of an RF bias; allowing for damage free processing. The preferred embodiment is an all-in-one processing reactor suitable for photovoltaic cell manufacturing, performing saw-damage removal, oxide stripping, deposition, doping and formation of heterostructures. The invention is scalable for atomic-layer deposition, etching, and other surface interaction processes. | 10-23-2014 |

20110044418 | LONG LIFE HIGH EFFICIENCY NEUTRON GENERATOR - The design of a compact, high-efficiency, high-flux capable compact-accelerator fusion neutron generator (FNG) is discussed. FNG's can be used in a variety of industrial analysis applications to replace the use of radioisotopes which pose higher risks to both the end user and national security. High efficiency, long lifetime, and high power-handling capability are achieved though innovative target materials and ion source technology. The device can be scaled up for neutron radiography applications, or down for borehole analysis or other compact applications. Advanced technologies such as custom neutron output energy spectrum, pulsing, and associated particle imaging can be incorporated. | 02-24-2011 |
20110091000 | METHOD AND SYSTEM FOR IN SITU DEPOSITON AND REGENERATION OF HIGH EFFICIENCY TARGET MATERIALS FOR LONG LIFE NUCLEAR REACTION DEVICES - Aspects of the invention relate to several methods to deposit and regenerate target materials in neutron generators and similar nuclear reaction devices. In situ deposition and regeneration of a target material reduces tube degradation of the nuclear reaction device and covers impurities on the surface of the target material at the target location. Further aspects of the invention include a method of designing a target to generate neutrons at a high efficiency rate and at a selected neutron energy from a neutron energy spectrum. | 04-21-2011 |
