  • Patent number: 7451664
    Abstract: A mechanical architecture for a user interface system enables the use of the low cost commercial load cells. Force inputs to a user interface that is rotatable about two perpendicular axes are reacted in each axis by cantilevered load cells. Two load cells react the loads in each axis, thereby enabling the system to exhibit quadruple redundancy in the load cells.

  • Patent number: 7413418
    Abstract: A compressor system that is configured to compress the fluid from low pressure source to a higher pressure magnitude is powered from the same low pressure fluid source. The compressor system includes two piston assemblies that are coaxially coupled to one another, and that are of differing cross sectional areas. The low pressure fluid is used to move the larger piston assembly, which is in turn used to move the smaller piston assembly. Low pressure fluid is selectively admitted to the smaller piston assembly, and movement thereof is used to compress the low pressure fluid to a higher pressure magnitude. The compressor system uses a fluidic bistable amplifier, which also coupled to the low pressure fluid source, to control low pressure fluid flow to the larger piston assembly, to thereby control its movement.

  • Patent number: 7111617
    Abstract: A diverter, apparatus and method of bypassing an exhaust gas recirculation cooler in order to selectively cool recirculated exhaust gas is disclosed. The diverter relies on the Coanda effect to direct the exhaust gas flow to the cooler or to a bypass around the cooler and thus preferred embodiments do not require a valve to be provided in the exhaust gas flow for this purpose. This simplifies the assembly of the diverter and apparatus and provides for a more reliable diverter compared to certain known systems.

  • Patent number: 7096888
    Abstract: A fluidic pulse generator system includes two fluidic diverter valves that are both controlled by a single fluidic pilot valve. The fluidic pilot valve and the two fluidic diverter valves are each adapted to receive a flow of pressurized fluid. The flow of pressurized fluid through the fluidic pilot valve is controlled in response to pressurized fluid flow through a control valve. In turn, the flow of pressurized fluid through the two fluidic diverters valves is simultaneously controlled in response to the flow of pressurized fluid through the fluidic pilot valve.

  • Patent number: 5386716
    Abstract: Fluidic proximity sensing apparatus for use with a linear induction motor car. The apparatus is comprised of a floating sensor head in operative combination with a dual flapper valve which forms two air gaps. A change in the proximity of the sensor head to a track surface is converted to a dimensional variation in the air gaps, which in turn is sensed by fluidic oscillators.

  • Patent number: 5374025
    Abstract: A vibration cancellation system having a fluidic driver providing fluid pressure differential and flow to an actuator having a reaction mass. The pressure differential drives the reaction mass so that the actuator's oscillations cancel any vibrations emanating from a vibrating structure mounted thereto.

  • Patent number: 5362987
    Abstract: A fluidic generator (38) employing a fluidic feedback oscillator (12) in combination with a magnetogenerator (41) is described. Oscillational changes in pressure produced within the feedback oscillator are transmitted to opposite sides of a pole cap (74) which reciprocates a coil (70) in a magnetic field.

  • Patent number: 5127622
    Abstract: A vibration cancellation mount for use in a vibration cancellation system is provided that includes a fluidic driver providing a modulated air stream to an elastomeric air spring. The pressure of the air stream is caused to fluctuate by an acoustical cancelling signal generated by an electroacoustic transducer electrically coupled to cancellation controller. As this pressure varies the air spring is filled and vented so that it responds at the same frequency and phase as the cancellation signal and thereby cancels the vibrations emanating from a vibrating structure mounted thereto. By employing a fluidic driver, the vibration cancellation mount is not frequency limited and can cancel vibrations having frequencies anywhere in the audio frequency spectrum.

  • Patent number: 5127173
    Abstract: A volumetric fluid flowmeter and method utilizes a venturi nozzle in the flow being measured, along with a negative feedback fluidic oscillator driven by a small bypass flow diverted from the main flow upstream of the venturi nozzle, and subsequently re-introduced into the main flow in the throat section of the venturi.

  • Patent number: 4949755
    Abstract: Fluidic volumetric flow meter method and apparatus wherein undesirable dynamic interaction (ringing) which could appear in an output signal is inhibited. Electrical isolation and shielding also contribute to a high quality output signal in accordance with the invention. Particularly advantageous housing structures adapt the flow measurement device to a variety of applications as a complete flow meter.

  • Patent number: H221
    Abstract: A ramjet fuel control system that provides a regulated fuel pressure of a predetermined differential between the fuel pump pressure and the inlet pressure to a metering valve. The differential regulator uses a spool valve and sleeve in which the sleeve has ports positioned to prevent hydrodynamic flow force while the sleeve metering valve spool has rectangular ports so that the metering area which is uncovered by the spool is linearly related to the stroke of the valve spool.
