Assignee:

Aerogen, Inc. - Sunnyvale CA

International Classification:

A61M 1600

US Classification:

12820016, 12820312

Abstract:

The invention provides methods and apparatus for nebulizing liquids. In one exemplary embodiment, an apparatus is provided which comprises a thin shell member having a front surface, a rear surface, and a plurality of apertures extending therebetween. The apertures are tapered to narrow from the rear surface to the front surface. A liquid supplier is further provided which delivers a predetermined unit volume of liquid to the rear surface. A vibrator vibrates the thin shell member to eject liquid droplets from the front surface of the thin shell member.

International Classification:

B05B 1706

US Classification:

12820016, 12820014

Abstract:

The invention provides exemplary aerosolization apparatus and methods for aerosolizing a substance. According to one exemplary method, a liquid is transferred from a first chamber into a second chamber having a substance that is in a dry state to form a solution. The solution is then transferred from the second chamber and onto an atomization member. The atomization member is operated to aerosolize the solution.

US Classification:

12820014, 12820312, 604 48, 604514, 604186, 604246

Abstract:

An apparatus to make a certain volume of liquid available for atomization comprises a container adapted to hold a liquid, and a piston pump. The piston pump comprises a piston member and a valve body, with the piston member being slidable within the valve body. Further, the valve body functions with the piston member to define a metering chamber. In this way, the metering chamber is adapted to be filled with liquid from the container when the piston member is moved to a filling position, and the piston pump is adapted to dispense a known volume of the liquid from the metering chamber when the piston member is moved to a dispensing position.

US Classification:

379 8813, 379 85, 706 62, 709219, 714 32

Abstract:

A system and method for representing call content in a searchable database includes transcribing call content to text. The call content is projected to vector space, by creating a vector by indexing the call based on the content and determining a similarity of the call to an atomic-class dictionary. The call is classified in a relational database in accordance with the vector.

Abstract:

A natural language business system and method is developed to understand the underlying meaning of a person's speech, such as during a transaction with the business system. The system includes a speech recognition engine, and action classification engine, and a control module. The control module causes the system to execute an inventive method wherein the speech recognition and action classification models may be recursively optimized on an unisolated performance metric that is pertinent to the overall performance of the natural language business system, as opposed to the isolated model-specific criteria previously employed.
