| 20110015914 | SPECIAL NUCLEAR MATERIAL SIMULATION DEVICE - An apparatus for simulating special nuclear material is provided. The apparatus typically contains a small quantity of special nuclear material (SNM) in a configuration that simulates a much larger quantity of SNM. Generally the apparatus includes a spherical shell that is formed from an alloy containing a small quantity of highly enriched uranium. Also typically provided is a core of depleted uranium. A spacer, typically aluminum, may be used to separate the depleted uranium from the shell of uranium alloy. A cladding, typically made of titanium, is provided to seal the source. Methods are provided to simulate SNM for testing radiation monitoring portals. Typically the methods use at least one primary SNM spectral line and exclude at least one secondary SNM spectral line. | 01-20-2011 |

| 20100282375 | Method of Fabricating a Uranium-Bearing Foil - Methods of fabricating a uranium-bearing foil are described. The foil may be substantially pure uranium, or may be a uranium alloy such as a uranium-molybdenum alloy. The method typically includes a series of hot rolling operations on a cast plate material to form a thin sheet. These hot rolling operations are typically performed using a process where each pass reduces the thickness of the plate by a substantially constant percentage. The sheet is typically then annealed and then cooled. The process typically concludes with a series of cold rolling passes where each pass reduces the thickness of the plate by a substantially constant thickness amount to form the foil. | 11-11-2010 |

| 20080299851 | PERSONAL WATER CRAFT TO ENABLE A USER TO WALK ON WATER - A water craft allows a user to travel across a surface of water utilizing a natural walking motion, which employs arms and legs for propulsion similar to cross-country snow skiing. The water craft includes a pair of skis adapted to fit on the user's feet. The skis can be coupled together by semi-elastic tethers. Each ski can include a foot well for receiving the user's foot. The foot well is designed to simulate the natural walking motion of the user. The user can propel the water craft using tail paddles and ski poles. The tail paddles are coupled to the rear of the skis. The tail paddles are configured to float on the water and to rotate about a transverse axis of the skis. The tail paddles are shaped to grip or “dig in” the water in response to the user moving the skis in a direction opposite the direction of motion of the water craft. The tail paddles provide resistance to propel the water craft when the ski is moved backward and slide along the water when the skis move forward. The ski poles include a paddle shaped to grip or “dig in” in response to the user pushing backwards on the ski poles. The paddle provides resistance to the backwards motion to propel the water craft forward. When the user pulls the ski poles forward, the paddles surface and slide across the water as the water craft moves forward. | 12-04-2008 |

| 20090219152 | PERSONAL ANNUNCIATION DEVICE - A personal annunciation device (PAD) providing, in an area of interest, compensatory annunciation of the presence of an abnormal condition in a hazardous area and accountability of the user of the PAD. Compensatory annunciation supplements primary annunciation provided by an emergency notification system (ENS). A detection system detects an abnormal condition, and a wireless transmission system transmits a wireless transmission to the PAD. The PAD has a housing enclosing the components of the PAD including a communication module for receiving the wireless transmission, a power supply, processor, memory, annunciation system, and RFID module. The RFID module has an RFID receiver that listens for an RFID transmission from an RFID reader disposed in a portal of an area of interest. The PAD identifies the transmission and changes its operating state based on the transmission. The RFID readers recognize, record, and transmit the state of the PAD to a base station providing accountability of the wearer. | 09-03-2009 |

| 20110254208 | HEAT TREATMENT FURNACE - A furnace heats through both infrared radiation and convective air utilizing an infrared/purge gas design that enables improved temperature control to enable more uniform treatment of workpieces. The furnace utilizes lamps, the electrical end connections of which are located in an enclosure outside the furnace chamber, with the lamps extending into the furnace chamber through openings in the wall of the chamber. The enclosure is purged with gas, which gas flows from the enclosure into the furnace chamber via the openings in the wall of the chamber so that the gas flows above and around the lamps and is heated to form a convective mechanism in heating parts. | 10-20-2011 |

| 20090211173 | COMPOSITE WIND TURBINE TOWER - A composite wind turbine tower, method for fabricating a composite wind tower and an apparatus for forming a composite wind tower. The tower includes a first layer and a second layer, each having a matrix material and a plurality of reinforcing fibers disposed in the matrix material. The tower further includes a core layer disposed intermediate to the first layer and the second layer. The tower is capable of being partially or fully fabricated on-site. | 08-27-2009 |
