    Abstract: A system for measuring water quality parameters, such as pH, CO2, alkalinity, and so forth, includes sensors or other measuring components integrated onto a circuit board. The circuit board may be contained within a submersible, watertight housing. A spectrophotometer may be located on the circuit board to measure the wavelength and intensity of light transmitted through the water being tested. Sensors for measuring salinity, pressure, temperature, or other properties may also be included on or near the circuit board. A microcontroller for processing these measurements is located on the circuit board. System components used to direct and filter the water, such as certain pumps, filters, and so forth, may be included in the housing off of the circuit board. Integrating the sensors and other measuring components onto a circuit board allows for a compact, low-cost water-quality-measuring system that is capable of making very accurate and precise measurements.

    Abstract: The present invention provides a fuel injection system in which fuel is delivered to the engine by varying the fuel pump pressure creating a variable flow rate through a fuel injector. The system comprises an engine control unit, a variable DC brushless motor fuel pump, and a fuel injector, wherein the engine control unit drives and varies the pump rate of the fuel pump to vary the fuel flow rate to the engine.

    Abstract: A positioning system is provided for use in a wind tunnel that results in accurate and dynamic orientation for a model while reducing aerodynamic interference. The system includes a pitch-yaw sleeve having a generally cylindrical shape and a torque tube disposed askew within the sleeve and rotatable about its longitudinal axis to drive a shaft. The shaft is generally elongated and crooked. The sting, to which a model is affixed, is rotatably attached to a distal end of the shaft. Rotation of the pitch-yaw tube and/or the pitch-yaw sleeve provides precise pitch and yaw orientation of the model, and rotation of the sting relative to the shaft provides precise roll orientation.

    Abstract: A VTOL aircraft includes at least one puller rotor and at least one pusher rotor. The VTOL aircraft, for example, may include three puller rotors and one pusher rotor. The combination of static puller and pusher rotors allows the rotors to remain in a fixed orientation (i.e., no moving mechanical axes are required) relative to the wings and fuselage of the VTOL aircraft, while being able to transition the aircraft from a substantially vertical flight path to a substantially horizontal flight path.

The system includes a pitch-yaw sleeve (36) having a generally cylindrical shape and a torque tube disposed askew within the sleeve and rotatable about its longitudinal axis to drive a shaft. The shaft is generally elongated and crooked. The sting, to which a model is affixed, is rotatably attached to a distal end of the shaft. Rotation of the pitch-yaw tube (38) and/or the pitch-yaw sleeve (36) provides precise pitch and yaw orientation of the model (14), and rotation of the sting relative to the shaft provides precise roll orientation.
