    Abstract: A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.

  • Patent number: 9771911
    Abstract: A fuel injection valve is attached to an engine and to have an annular seal material attached thereon. The seal material is attached to a first reduced diameter part. In a use state where a body is inserted in an attachment hole formed at a predetermined position of the engine and a gas pressure that is equal to or higher than a predetermined pressure is applied to the seal material from its nozzle hole-side, the seal material is pressed against a first tapered part by the gas pressure to be compressively deformed, and a clearance between an inner peripheral surface of the attachment hole and an outer peripheral surface of the body is sealed with a compressively-deformed part of the seal material. A taper angle of the first tapered part is set in a range from 10 degrees to 20 degrees.

  • Patent number: 9752789
    Abstract: A humidifying apparatus includes a nozzle and a base on which the nozzle is mounted. The nozzle has respective first and second air inlets, air outlets and interior passages for conveying air therefrom and thereto. The nozzle defines a bore through which air outside the humidifying apparatus is drawn by air emitted from the air outlets. The base generates first and second air flows through the respective first and second interior passages, and a water reservoir. First and second air passageways convey the first and second air flows to the respective first and second air inlets. As the second air passageway conveys the second air flow over the water in the reservoir, water stored in the reservoir is agitated. An ultraviolet radiation generator irradiates the agitated water for a period of time before water stored in the reservoir is atomized to increase the humidity of the second air flow.
