摘要： A device and method for controlling the flow of a gaseous fuel from a fuel supply to a pressurized combustion chamber. A fuel pump is included in the gas train from supply to chamber. The fuel pump increases the pressure of the gas to allow efficient injection into the chamber. The pump is modulated to control the fuel flow. Both alternating current and pulse-width-modulated direct current signals may be used to control the flow. The pump may be a piston pump or a diaphragm pump. Feedback may be provided from sensors that determine operating parameters of the engine and such sensor signals may be used by the controller to maintain a parameter, such as temperature, at a specified value. An acoustic filter can be included in the gas train to significantly reduce gas flow pulsations generated by the pump. This filter improves the uniformity of the combustion process.

摘要： A digitizing scanner particularly for scanning transparent films such as X-rays provides an improved illuminator for transmitting light through the film. The illuminator defines a line array of a plurality of individually calibrated and controlled LEDs. The LEDs are calibrated by determining their relative points of projection on a CCD camera array. The camera array scans the LEDs and adjusts them individually to produce a predetermined illumination pattern from the group. The adjustment occurs over a plurality of cycles that address cross-talk between LEDs in the array. The camera includes anti-reflection elements to minimize bounce-back of image light and noise suppression circuitry to reduce low-level signal noise. A central processing unit, interconnected with the camera assembly includes a pixel averager to reduce the inherent resolution of the CCD to a desired level and to attenuate further noise. The scanner can include an illuminator for illuminating a scannable opaque bar-code strip and size-measurement circuitry for determining the relative size and location of the scanned image.
摘要翻译：特别用于扫描诸如X射线的透明膜的数字化扫描器提供了用于透过膜的光的改进的照明器。照明器定义多个单独校准和控制的LED的线阵列。通过确定它们在CCD相机阵列上的相对投影点来校准LED。相机阵列扫描LED并分别调整它们以从组中产生预定的照明图案。调整发生在解决阵列中的LED之间的串扰的多个周期中。相机包括防反射元件，以最小化图像光和噪声抑制电路的反弹，以降低低电平信号噪声。与相机组件相互连接的中央处理单元包括像素平均器，以将CCD的固有分辨率降低到期望的水平并衰减进一步的噪声。扫描器可以包括用于照亮可扫描的不透明条形码条的照明器和用于确定扫描图像的相对尺寸和位置的尺寸测量电路。
