20090065637 | Buoyancy system using double-sorb controllers for engine fueling and airship attitude correction - A buoyancy system using double-sorb controllers for engine fueling and airship attitude control is disclosed. The buoyancy system is based on the use of a Liquefied Natural Gas (LNG) payload that assists in buoyancy control and provides simultaneously a fuel for natural gas engines that propel the airship. The airship attitude correction is achieved by changing the amount of buoyant gas such as methane that is enclosed in the airship's baffles located forward and aft in the airship, and to the starboard and port if necessary for active roll control. The airship attitude control is provided by absorption or desorption of the natural gas using two double-sorb controllers. One of two double-sorb controllers is mounted forward and the other is mounted aft in the airship, so the differential absorption/desorption of natural gas is used to control the pitch of the airship. Each double-sorb controller consists of a thermally insulated external container connected with the LNG payload and natural gas engines. The double-sorb controller includes two sorbs equipped with heaters and separated by vacuum space and thermally conductive shell. The first sorb is connected with the airship's baffle to absorb or desorb the natural gas enclosed in the baffle, and the second sorb is connected to the natural gas engine. The LNG payload controls the level of the vacuum in a space that completely surrounds the first sorb. By the regulation of temperature increase or decrease of two sorbs within the double-sorb controllers, the fueling of the natural gas engines and the airship attitude control is achieved. A second system may be used to plumb the natural gas boil-off into or out of each baffle as necessary to provide course control of the overall airship, and buoyancy and attitude control. Other liquefied or solidified gases such that the gas phase of the material is lighter than air, such as hydrogen, may be substituted for natural gas in this invention. All lighter than air airships, including but not limited to blimps, may be controlled using the invention described herein. | 03-12-2009 |

20090275946 | Intramedullary Fixation Device for Small Bone Fractures - A fracture fixation system particularly useful for bones of the hand and foot is disclosed. The system uses curved shape-memory alloy (e.g., Nitinol) wires that have a predetermined radius of curvature to accommodate different sized bones. These shape-memory alloy wire forms can be inserted into phalanx, metacarpal or metatarsal bones via a percutaneous technique. The technique uses small skin incisions; a specialized drill guide that has holding K-wires to maintain fixation of the drill guide to the bone so that it does not lose the insertion point; a specialized drill as well as a specialized wire cutter and advancement tool to make sure that the level of the wire is below the level of the outer cortical bone. Shape-memory alloy (e.g., Nitinol) based wires with a pre-bent curve have an advantage over the typical standard K-wire in that they can spring back to their predetermined memory shape when inserted into the intramedullary canal of the bone and heated, i.e., a more aggressive curve. By increasing their bending or flexion to increase the arc of curvature, this allows fixation points for the wire, essentially locking it to bone. | 11-05-2009 |

Then a calculation is made to determine how to modify moisture content in order to maximize the value of the lumber. In yet another embodiment, geographic positions of individual packages are tracked in the kiln. The efficiency of the kiln is determined based on drying uniformity of the packages. Then the moisture content can be modified to determine how it impacts value of a charge of lumber. | 04-08-2010 |
20110277547 | MEASURING HUMIDITY OR MOISTURE - An apparatus for measuring humidity or moisture, such as in concrete, is described comprising a sensor module comprising a humidity or moisture sensor in electrical communication with a first set of terminals and a hand-held reader module comprising a controller in electrical communication with a second set of terminals that are mateable with the first set of terminals such that the hand-held reader module is electrically connectable to and electrically disconnectable from the sensor module. The hand-held reader module is configured to read data from the sensor in response to making electrical connection with the sensor module. One set of terminals can comprise plural connector pins and the other set of terminals can comprise plural landing pads, such that the plural connector pins and the plural landing pads make a same electrical connection regardless of the rotational orientation of the hand-held reader module relative to the sensor module. | 11-17-2011 |
