Automated fire control device
A device that causes a weapon to fire upon a target when the weapon is enabled by an operator, and when the weapon point of impact passes through a target or in a proximity thereto and when the target satisfies certain criteria as determined by one or more sensors/designations.This invention represents a significant paradigm shift. Some prior art (large scale) weapons automatically acquire/track/prioritize/target/fire upon targets without operator intervention (i.e. Phalanx). Most prior art weapons, especially but not limited to small arms, are manually aimed, and fire immediately upon an input (trigger pull, or equivalent) from the operator. The current invention is a novel approach which triggers the release of a round, multi-round burst, rocket, missile, or other projectile(s) when enabled by the operator, and when the target passes through the point of impact (or desired/computed proximity thereto), relieving the operator of the split second judgment in timing the release and/or cessation of such fire. The results intended include a reduction in off-target rounds fired, increased hit rate, conservation of ammunition, more effective targeting for non-motion-stabilized weapons (in particular small/medium arms), and the introduction of a backup mode for nominally motion-stabilized weapons which may allow effective operations when primary stabilization systems fail or are overwhelmed by dynamics.This invention is applicable (in embodiments of varying complexity) to weapons ranging from handheld pistols to the main (artillery) gun of a tank, a ship, or the cannon aboard an aircraft. |

Illuminated laminate with superior aesthetics and brightness
The trend towards increasing the glazed area in automobiles has reduced the potential locations for mounting cabin lighting. This is especially true for vehicles having large panoramic glazing.

Well-fouling abatement system and method for wells
Exemplary embodiments seek to eliminate or reduce fouling enabled by atmospheric oxygen entering the airspace of the well column. An inerting gas is used to flush atmospheric oxygen out of the well airspace. Once atmospheric air in the well gas-column has been replaced with an inerting gas, the well is sealed and pressurized with the inerting gas. The introduction of atmospheric oxygen back into the system through leaks is overcome by keeping a small, positive pressure-differential between the well-column gas pressure and the atmosphere. Results, as described herein, have shown the removal of atmospheric oxygen from the system can greatly reduce, or eliminate, both chemical and biological fouling as well as reduce or eliminate the need for well cleaning treatments. |

A waste water treatment system for removing contaminant chemicals, bacteria and organic matter to reduce the chemical oxygen demand (COD) and the biological oxygen demand (BOD). The system uses thermal energy to remove chemicals that can be oxidized to reduce the COD, and to destroy bacteria and organic matter to reduce the BOD of the treated water. The system can include an expansion chamber and a nozzle to create steam which can be used as thermal energy to heat the waste water and provide the proper treatment to reduce the COD and BOD of the processed waste water. |

Method for producing sulfide solid electrolyte
A method for producing a sulfide solid electrolyte includes a firing step of firing a raw material containing Li2S in a hydrogen sulfide-containing atmosphere at a temperature of 300° C. or higher, Li2S having a purity of 50 to 90% by mass at the start of firing. The Li2S may contain impurities including at least one of LiOH, Li2O, LiHCO3, and Li2CO3. In the firing step, it is preferable that a concentration of a hydrogen sulfide in the hydrogen sulfide-containing atmosphere is 50 volume % or more. It is preferable that the raw material further contains P2S5 and LiX (X represents at least one type of elemental halogen), and the sulfide solid electrolyte has an argyrodite-type crystal structure. |

Systems and methods for increasing the hydrogen permeance of hydrogen-separation membranes in situ
Hydrogen-producing fuel processing systems and related methods. The systems include a hydrogen-producing region configured to produce a mixed gas stream from a feedstock stream, a hydrogen-separation membrane module having at least one hydrogen-selective membrane and configured to separate the mixed gas stream into a product hydrogen stream and a byproduct stream, and an oxidant delivery system configured to deliver an oxidant-containing stream to the hydrogen-separation membrane module in situ to increase hydrogen permeance of the hydrogen-selective membrane. The methods include operating a hydrogen-producing fuel processing system in a hydrogen-producing regime, and subsequently operating the hydrogen-producing fuel processing system in a restoration regime, in which an oxidant-containing stream is delivered to the hydrogen-separation membrane module in situ to expose the at least one hydrogen-selective membrane to the oxidant-containing stream to increase the hydrogen permeance of the at least one hydrogen-selective membrane. |

Safety stirrup
A safety stirrup includes a C-shaped frame and a supporting assembly. A pivot portion and a first connecting portion are respectively disposed at two ends of the opening of the frame. An arm with a second connecting portion is pivotally connected to the pivot portion and is selectively connected with the first connecting portion. The supporting assembly consists of a first plate, a second plate with elasticity and a third plate. The third plate is stacked on the bottom portion of the frame. The second plate is stacked on the third plate. The first plate is stacked on the second plate with a higher position of a front end than that of a rear end. |

Contactless liquid dispensing valve
A contactless valve configured to dispense a liquid can include an actuator configured to move a plug between a closed position in which the plug prevents the flow of liquid through valve body, and an open position in which liquid can be dispensed through an outlet. The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor. The controller can be configured to switch the presence sensor into the activated state in response to the detection of the prerequisite condition by the activation sensor, and to control the actuator to move the plug from the closed position to the open position in response to the detection of the object in the upper detection zone by the presence sensor. |

Method and filling system for filling containers
A filling method includes executing a pre-stressing phase, during which, at plural time intervals, gas is drawn from a gas space that lies above the filling material in a tank. The gas pre-stresses a container up to a second pressure that is below the pressure in the gas space. During a filling phase, a liquid valve opens to allow the filling material in the tank to enter into the container. This valve is above the level of the filling material, thus preventing gravity from driving the flow. |
