Following our previous report concerning the development of a 127 μm resolution, 7.4 million pixel, 30 x 40 cm active area, flat panel amorphous Silicon (a-Si) x-ray image sensor, this paper describes enhancements in image sensor performance in the areas of image lag, linearity, sensitivity, and electronic noise. New process improvements in fabricating a-Si thin film transistor (TFT)/photodiode...

PURPOSE To evaluate the quality of vision and depth of focus induced by controlled amounts of negative spherical aberration in patients implanted bilaterally with light-adjustable intraocular lenses. DESIGN Prospective, nonrandomized clinical trial. METHODS Seventeen patients were implanted and treated with appropriate spatial irradiance light profiles. One eye was set for emmetropia, and t...

in conventional cultivation of sugar beet the weeding and crust breaking are mostly performed manually. the objectives of this research were to design, fabricate and evaluate a soil crust breaker and weeding implement equipped with a detecting sensor. each unit consisted of a distance detecting sensor and a hydro-motor for driving the blades and pneumatic valves for moving the blades. the hydro...
