Abstract: A two-stage fluid control valve includes a first stage electronically switchable, bi-stable two-port valve movable between an open position and a leak-free closed position, and a second stage microvalve configured to control the flow of fluid through a fluid outlet of the two-stage fluid control valve when the first stage electronically switchable, bi-stable two-port valve is in the open position. The electronically switchable, bi-stable two-port valve is disposed between the second stage microvalve and a fluid inlet of the two-stage fluid control valve.

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: A microvalve includes a first plate having a surface defining an actuator cavity. A second plate has a surface that abuts the surface of the first plate and includes a displaceable member that is disposed within the actuator cavity for movement between a closed position, wherein the displaceable member prevents fluid communication through the microvalve, and an opened position, wherein the displaceable member does not prevent fluid communication through the microvalve. An actuator is connected to the displaceable member and has only one or two pairs of actuator ribs.

Abstract: A system for controlling fluid pressure to a transmission system through a MEMS microvalve includes a transmission controller configured to receive a target command pressure, a current system command pressure input signal, and a transmission system operating temperature. A power determination module determines a temperature-related power factor from the target command pressure, the current system command pressure input signal, the transmission system operating temperature received in the controller, and a look-up table within the controller. A power signal module adjusts the current system command pressure input signal by the temperature-related power factor and applies the adjusted current system command pressure input signal to the MEMS microvalve via the controller.

Abstract: A plate is adapted for use in a microvalve and includes a displaceable member configured for movement between a closed position, wherein the displaceable member prevents fluid communication through the microvalve, and an opened position, wherein the displaceable member does not prevent fluid communication through the microvalve. The displaceable member includes an elongated arm portion, a plurality of actuator ribs connected through a central spine to the elongated arm portion, and a hinge portion. The actuator ribs have a first portion and a second portion, the first portion having a first end and a second end, the second end of the first portion connected to the central spine, the second portion having a first end and a second end, the second end of the second portion connected to the central spine. A channel is formed in the plate. A plurality of elongated openings are 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 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.
