    摘要: A level shifter circuit for shifting from a first voltage level technology (such as 0.9 volt) to a second level voltage technology (such as 3.3 volt) with increased switching speed. The increased speed is achieved by adding a boost circuit to the pull-up transistors to boost the switching speed and shut itself down after the transition. The level shifter circuit does not require intermediate level transistors or intermediate level voltage sources.

    摘要: A system (200) and method (800) for determining whether a sample object (203) has a color that is within a predetermined range is provided. The system (200) includes a light source (201) capable of projecting lights having different light wavelength spectrum upon the sample object (203). A controller (222) causes the light source (201) to project a first light wavelength spectrum upon the sample object (203), then another, then another, and so forth. While each light is projecting upon the object, a monochromatic image capture device (202) captures an image having luminous intensity information. The luminous intensity information, or a subset thereof selected by an image selection tool (232) is then compared to the statistical range, which is derived from a plurality of images taken of a reference object (403).
