International Classification:

F02G 5/00
US Classification:

123549, 123557
Abstract:

There is provided a fuel injector system for vaporizing liquid fuel and metering the vapor to an internal combustion engine of an automobile. The system has at least one fuel injector with at least one capillary flow passage with a heat source arranged along the flow passage capable of heating liquid fuel in the flow passage to a level sufficient to vaporize it, a solenoid operated metering valve located at the capillary outlet for metering vaporized fuel to the internal combustion engine, and a system for operating the metering valve while delivering the vaporized fuel at an opening and closing frequency of at least 15 Hz or more preferably at least 60 Hz independent of engine rpm. The system is expected to be useful for starting a cold engine with reduced emissions.

Abstract:

A drug delivery system, which includes an aerosol generator unit, a pumping unit, a flow tube, at least one condensate collector and an aerosol transition adapter. The aerosol generator forms an aerosol from a liquid formulation, which is partially volatilized. The pumping unit supplies the liquid formulation to the aerosol generator unit and a flow tube having an inlet end in fluid communication with an outlet of the aerosol generator unit and an outlet adapted for connection to a patient interface, which supplies ventilation gas to a patient's lungs. The system also includes at least one condensate collector adapted to collect condensed liquid or liquid produced by the aerosol generator unit, and a transition adapter arranged to mix aerosol produced by the aerosol generator unit with heated air or ventilation gas and direct the mixed aerosol into the inlet end of the flow passage.

US Classification:

392397, 392385, 392399
Abstract:

An aerosol generation system having an aerosol generator wherein a liquid formulation is at least partially volatilized in a capillary passage and discharged from the capillary passage to form an aerosol. The aerosol generation system includes a pumping unit adapted to supply a liquid formulation to the aerosol generator; and a fluidic element located between the pumping unit and the capillary passage of the aerosol generator, wherein the fluidic element increases backpressure of the liquid formulation as the liquid formulation enters the capillary passage of the aerosol generator.

US Patent:

20060047368, Mar 2, 2006
Filed:

Sep 2, 2004
Appl. No.:

10/932257
Inventors:

Niranjan Maharajh - Richmond VA, US
Chris Tucker - Midlothian VA, US
David Keeler - Midlothian VA, US
International Classification:

B05B 17/00
A61M 11/00
US Classification:

700283000, 128200140
Abstract:

A programmable vapor generator forms a volatilized liquid by supplying a material in liquid form to a flow passage and heating the flow passage, such that the material volatilizes and expands out of an outlet of the channel. The volatilized material, if desired, mixes with ambient air such that volatilized material condenses to form the aerosol. An apparatus and method for generating such a volatilized liquid, as well as the control and methods of heating, are disclosed as an analytical tool useful for experimental use, a tool useful for production of commercial products or an inhaler device.

International Classification:

A61B 5/00
A61B 5/1455
A61B 7/00
A61B 5/0205
Abstract:

An apnea analysis system may include a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. An apnea analysis system includes a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. The PPG sub-system is configured to be operatively connected to an individual and output a PPG signal from the individual. The breath detection sub-system is configured to be operatively connected to the individual and output a breath signal from the individual. The apnea analysis module is in communication with the PPG sub-system and the breath detection sub-system. The apnea analysis module analyzes the breath signal and a respiratory component of the PPG signal and, based on the analysis, identifies a presence of apnea, differentiates between obstructive apnea and central apnea, and provides an indication of the identified apnea.
