Abstract: A microvalve includes a displaceable member having an elongated arm portion, a plurality of actuator ribs connected through a central spine to the elongated arm portion, and a hinge portion. Each of the actuator ribs has a first portion and a second portion, the first portions each having an end connected to the central spine, the second portions each having an end connected to the central spine. A channel is formed in the plate. A plurality of elongated openings is formed in the plate and define the actuator ribs, each elongated opening having longitudinally extending side edges. One of the elongated openings separates each rib in the second portion of ribs from an adjacent rib or the plate. The channel and a longitudinally extending side edge of one of the elongated openings separate the second portion of the actuator ribs from the plate and define an electrical isolation region.

Abstract: An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece, an actuator, a flow control canister valve assembly attached to the aerosol container, a battery, and an electronically controlled flow control valve electronically connected to the battery and in fluid communication with the flow control canister valve assembly. The aerosol container and the attached flow control canister valve assembly are further attached to the actuator and the actuator is mounted for slidable movement within the discharge piece. The flow control canister valve assembly is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control canister valve assembly to the electronically controlled flow control valve, and a closed position wherein the aerosol formulation is not permitted to flow through the flow control canister valve assembly to the electronically controlled flow control valve.

Abstract: An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a flow control valve mounted within the discharge piece, a battery, and an electronically controlled metering valve electronically connected to the battery and in fluid communication with the flow control valve. The flow control valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control valve to the metering valve, and a closed position, wherein the metering valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece. A solenoid is electronically connected to the battery and is movable between an actuated position wherein the solenoid urges the flow control valve into the open position, and an un-actuated position wherein the flow control valve remains in the closed position.

Abstract: The electronically switchable MEMS valve includes a housing formed from soft magnetic material and defining a fluid flow path therethrough. A magnetic field generating member is mounted within the housing and connected to a source of electrical power. A MEMS valve portion is mounted within the magnetic field generating member, has a valve closing member movably mounted therein, and defines a portion of the fluid flow path therethrough. The valve closing element is movable between a closed position wherein the fluid flow path is blocked, and an open position wherein the fluid flow path is not blocked. When an electric current is removed from the magnetic field generating member, the valve closing element is configured to move to and remain in the one of the closed position and the open position to which the valve closing element is the closest when the electric current is removed.
