Filed:

Oct 28, 2005

Appl. No.:

11/262004

Inventors:

Andy R. Askew - Pfafftown NC, US
Gregory S. Lyon - Mamaroneck NY, US

International Classification:

H01L 41/053

US Classification:

310328, 310324, 310332, 310344, 310348

Abstract:

An actuator is disclosed, which includes a piezoelectric bimorph. The actuator also includes a substantially moisture impervious and electrically insulating packaging having a cavity around the bimorph providing for a clearance around the bimorph. The packaging includes a carrier having first and second surfaces and an aperture wherein the bimorph is disposed, the packaging further includes first and second cover films selectively attached to the first and second surfaces respectively, and at least one flex circuit connected to the bimorph for supplying electrical energy thereto.

International Classification:

F16K 31/02

US Classification:

137 1, 1374875

Abstract:

An electro-pneumatic transducer for controlling gas pressure is disclosed. The transducer includes a nozzle body and a valve housing interconnected therebetween by a nozzle and a solenoid assembly including a magnetized valve assembly and a solenoid having a top portion and a bottom portion, which when energized generate a magnetic field having a predetermined polarity in response to which the magnetized valve assembly is actuated to control gas flow through the nozzle. The transducer also includes a control circuit adapted to receive an input signal. The control circuit is configured to energize the solenoid in response to the input signal to generate the magnetic field thereabout to actuate the valve assembly. The transducer further includes a capacitor coupled to the control circuit, wherein upon loss of the input signal, the control circuit signals the capacitor to provide an electrical signal to the solenoid to actuate the valve assembly.

International Classification:

H04R 1/42
G05D 16/20

US Classification:

381165, 25112915

Abstract:

Systems and methods for a high performance transducer are disclosed. For example, one described transducer includes: a pressure locking chamber with at least one orifice; a two-state solenoid configured to be controlled by a control circuit and a capacitor, the two-state solenoid comprising a solenoid housing; and a permanent magnet assembly configured to be actuated by the two-state solenoid to move between an open and a closed position, the permanent magnet assembly comprising a stopper configured to seal the at least one orifice in the closed position.
