摘要： The present invention is a portable electronic video display. The display is configured to be worn on the arm or wrist of a user, or stored in a pocket or backpack. The display is raised to eye level and the user looks through an eyepiece to view the video display. Control buttons are located on the display for generating point and click type commands. The display is meant to be used remotely from a computer. The computer could be worn or carried by the person or simply be free standing, some distance away. The computer is configured to convert video signal into a serial data stream and then transmit that stream via an RF signal. The display then receives that signal and converts it back into a video signal, displaying it on a miniature electronic video display. That image is them magnified through various optics to present a final image to the user. The point and click commands are separately transmitted back to the computer, where they are received and acted upon.

摘要： The present invention is a proximity detector for an electronic device. The proximity detector utilizes two capacitors which share a common electrode. The two capacitors are located on the housing of the electronic device. The capacitors are arranged so that when the electronic device is used in its normal orientation, a portion of the operator's body will occlude one of the capacitors, but not the other. The close proximity of the operator's body will change the electric field surrounding the capacitor. Thus, the capacitance of the occluded capacitor will be different than the unencumbered capacitor. A detection circuit is coupled to the capacitors and to the power supply of the device. The circuit uses very little power, and maintains the electronic device in a standby or powered down mode. Only when the circuit detects a difference in the capacitance generated by the two capacitors, will it allow full power to be delivered to the electronic device.

摘要： A method and system for controlling fuel flow in a fuel metering system that includes a metering valve and a proportional bypass valve that produces a differential pressure error across the metering valve includes supplying a first fraction of fuel through the metering valve. A second fraction of the fuel is directed through the proportional bypass valve. The differential pressure error produced by the bypass valve is determined, and fuel flow through the supply line is controlled by adjusting the metering valve based at least in part on the determined differential pressure error, and by adjusting the proportional bypass valve to maintain a substantially constant metering valve differential pressure across the metering valve.

摘要： An apparatus for providing a backup fuel metering system for the gas generator section (24) of a gas turbine engine (10) is disclosed that includes a gas generator (24) and an augmentor (40). The apparatus includes a gas generator fuel metering system (52) providing fuel to the gas generator nozzles (32) and an augmentor fuel metering system (54) providing fuel to an augmentor (40). The augmentor fuel system (54) includes a diverter valve (88) which selectably directs fuel to the augmentor (40) during augmentation operation or to the gas generator nozzles (32) during a gas generator metering system failure or critical engine operation. The system allows the gas generator nozzles (32) to be supplied with fuel flow from the gas generator metering system (52), the augmentor metering (54) system or both. When the gas generator nozzles (32) are being supplied with flow from both metering systems the system is capable of improved fault accommodation.
