Abstract: A breath actuated nebulizer for efficiently and reliably delivering aerosolized liquid to an inhaling patient is disclosed. The nebulizer includes a valve assembly having an actuator piston for quickly responding to an inhalation and beginning the nebulization process, and a relief piston to lower the inhalation effort required of the inhaling patient. Also provided is a method of providing breath actuated nebulization including the steps of moving an actuator piston connected to a diverter so that the diverter reaches a nebulizing position during an initial period of inhalation, and moving a relief valve to allow a greater flow of air, and thereby reduce inhalation effort, after the initial period of inhalation.

Abstract: An aerosol dispensing inhaler training device for determining whether a user is properly operating an aerosol dispensing device. The training device includes an aerosol dispensing device having a container with a valve stem extending longitudinally therefrom and movable between a closed position and an open position. The container dispenses a portion of the contents within the container when the valve stem is moved to the open position. The aerosol dispensing device includes a housing adapted to support the container reciprocally moveable within the housing along a longitudinal axis from a first position, the housing comprising a well adapted to receive the valve stem and an exhaust port comprising one end in fluid communication with the well and a second end in fluid communication with the ambient atmosphere, wherein the portion of the contents within the container is dispensed from the first end of the exhaust port to the second end of the exhaust port when the housing moves to an actuation position where the valve stem is actuated so that a portion of the contents within the container is dispensed through the second end of the exhaust port when the valve stem is moved to the open position. An actuation sensor generates a signal that indicates when the housing is moved to the actuation position and the valve stem is actuated. A shake sensor determines whether the contents within the container have been properly agitated for consumption by a user.

Abstract: There is described an optical radiation sensor device for detecting radiation in a radiation field. The device comprises a sensor element capable of detecting and responding to incident radiation from the radiation field and a radiation window interposed between the sensor element and the radiation field. The radiation window comprises a non-circular (preferably square) shaped radiation transparent opening. The optical radiation sensor device can be used in a so-called dynamic manner while mitigating or obviating the detection errors resulting from the use of a circular-shaped attenuating aperture and/or angular (even minor) misalignment of the sensor device with respect to the array of radiation sources when multiple such circular-shaped attenuating apertures are used.
