摘要:
This invention discloses a chamber adapted for the administration of medication from a source of aerosolized drug, such as a metered dose inhaler (MDI) or nebulizer, comprising a conduit with an oval cross section, a mounting for the MDI at the rear, an annular one-way valve at the front in fluid communication with the inhalation airway of the patient that permits air to flow out of the chamber during an inhalation by the patient, but prevents exhaled air from entering the chamber, an exhaust valve in the front section that provides an effective seal during inhalation, and a solid state whistle, wherein the whistle is adapted to making a sound if the air pressure within the chamber is below a predefined threshold. The inventive chamber may be used to directly administer inhaled medication to the mouth of a patient, or it may be used with an inhalation mask.
摘要:
A method and apparatus for producing metastable nanostructured materials employing a ceramic shroud surrounding a plasma flame having a steady state reaction zone into which an aerosol or liquid jet of solution precursor or powder material is fed, causing the material to be pyrolyzed, melted, or vaporized, followed by quenching to form a metastable nanosized powder that has an amorphous (short-range ordered), or metastable microsized powder that has a crystalline (long-range ordered) structure, respectively.
摘要:
A system and method for aircraft taxiing and guidance using ground station's communication network is disclosed. In one embodiment, in a method of aircraft taxiing and guidance, a communication link between an aircraft computing system and a ground station system is established using a communication network provided by the ground station system. An aircraft taxi selection and guidance application residing in the aircraft computing system is displayed on a display device upon establishing the communication link. Further, one or more pilot selectable taxiing and ground services are displayed upon selecting the aircraft taxi selection and guidance application. One of the displayed pilot selectable taxiing and ground services is selected by a pilot of an aircraft. Information associated with the selected pilot selectable taxiing and ground service is then displayed on the display device using ground station data. The aircraft is taxied and guided by the pilot using displayed information.
