摘要： A method for testing a fuel injector including providing an engine with a common rail fuel injection system having one or more fuel injectors; operating the engine at a selected set of operating conditions; conducting a motoring event; allowing a first settling duration; measuring a first rail pressure; operating a first selected injector including operating the first selected injector singly in response to a selected fuel quantity, a selected number of combustion cycles, and a selected number of injections per combustion cycle; allowing a second settling duration; measuring a second rail pressure; calculating a pressure difference value in response to the first rail pressure and the second rail pressure; inferring an amount of fuel delivered by the first selected injector in response to the pressure difference value; and evaluating a first performance factor of the first selected injector in response to the amount of fuel delivered.

摘要： A miniature optical scanner includes an electromagnetic drive having stationary magnets and stationary drive coils to minimize the rotational inertia of the scanner and increase the scanner's resonant frequency. The scanner is such that the resonant frequency is manually tunable as well as automatically adjustable to compensate for variables causing frequency drift. The optical scan angle is increased by employing a multiplying mirror with the optical scanner. For a two axis scanning system, the multiplying mirror may be formed of a second optical scanner to increase the optical scan angle relative to both of the axes.

摘要： A virtual retinal display utilizes photon generation and manipulation to create a panoramic, high resolution, color virtual image that is projected directly onto the retina of the eye. The virtual retinal display includes a source of photons, the photons being modulated with video information and scanned by a scanning system in a raster type of pattern directly onto the retina of the user's eye. A single, monofilament optical fiber of very small diameter couples light from the photon generator to the scanning system so as to provide to the scanning system a point source of light at the fiber's exit aperture. The photon generator may utilize coherent or non-coherent light. Further, the photon generator may utilize color light emitters so as to scan a colored virtual image directly onto the retina of the user's eye.
