摘要： A sensor for use in an optic system to detect current conditions in an environment. The sensor has a crystal member with a first waveguide extending from a top surface and a second waveguide extending from a bottom surface of a core member. Polarized light waves from a source are simultaneously communicated to the first and second waveguides. A first pressure is communicated to the top surface of the crystal member and an unknown pressure corresponding to the pressure of the environment is communicated to the bottom surface of the crystal member. The first pressure and the unknown pressure develop a pressure differential which acts on the crystal member to deform the first and second waveguides. The deformation of the first and second waveguides modifies the polarized light waves to create first and second output waves which are communicated to an optical interface where differences therebetween are extracted. The differences are analyzed by a computer to identify the current pressure and temperature of the environment.

摘要： A direct metering fuel supply system includes a plurality of axial gap motors, a fixed displacement, variable speed positive displacement piston pump, and a gas turbine engine control. Each axial gap motor is configured to be selectively energized and is operable, upon being energized, to supply a drive torque at a drive speed. The fixed displacement, variable speed positive displacement piston pump is coupled to each of the axial gap motors to receive the drive torque selectively supplied therefrom and is operable, upon receipt of the drive torque, to supply fuel at a flow rate dependent on the drive speed. The gas turbine engine control is adapted to receive fuel flow commands and is operable, in response to the fuel flow commands, to energize one of the plurality of axial gap motors.

摘要： A fuel control valve (100) includes a rotary throttling valve assembly (4,7) providing one or more of the benefits of being lightweight, having a relatively low power consumption, having a fail-closed structure and/or zero leakage. The fuel control valve (100) is a rotary, throttling valve that is actuated via a rotary torque motor (70). The valve (7) can be spring loaded for providing positive shutoff. Position indication of the valve (7) is obtained via a position sensor (31) and cam (13) mounted to the throttling valve shaft at a driven end (98). In a de-energized state, a torsion spring (45) is provided that is loaded to rotate the valve (7) to the closed position. The fuel control valve (100) may be advantageously utilized in extreme operating environments, e.g., such as extreme temperature and vibration environments found in missile control fuel systems.

摘要： The invention relates to a micro-optic switch used for transmitting optical signals between optical fibers. More particularly, the invention pertains to a micro-optic switch using polymer structures to position a microactuator and optical fibers on a substrate so that the microactuator can move an optical fiber cantilever between two fixed fibers to transmit optical signals between either one of the fixed fibers and the cantilever fiber. Using polymers instead of micromachined structures to position components of the switch reduces cost and simplifies assembly. The invention further provides processes for producing a micro-optic switch and for switching the path of an optical signal.

摘要： A high response valve (10) has a leaf spring (25) preloaded and positioned over an orifice plate (23). The orifice plate (23) has a plurality of interleaved ridges (62, 64) and grooves (61, 63, 65) with the grooves being in continuous communication with a valve inlet (13, 19). A plurality of slits or openings (49, 51) in the aperture plate (23) are in continuous communication with a valve outlet (21), each opening (49, 51) passing through a corresponding ridge (62, 64). A pair of electromechanical transducers (27, 29), each comprising a generally cylindrical stack of piezo-electric disks having a central axis (71), actuate the valve (10). One end of each stack (27, 29) is adjustably fixed relative to the housing by adjustment screws (41, 43), and a cap (35, 37) at the other end of the stack couples the stack to a corresponding spring (25) end. Each cap (35, 37) includes a notch (39) for engaging and maintaining a corresponding spring end near the corresponding central axis (71). Energization of the piezo-electric stacks (27, 29) applies an additional axial load to the spring (25) and proportionally opens the flow area of the valve (10). The high mechanical forces available from a piezoelectric actuator permits the construction of very stiff systems with high natural response frequencies, and the plurality of openings (49, 51) provide an effectively large total flow area.
