Abstract: An optical object detection apparatus and associated methods. The apparatus may comprise a lens (e.g., fixed-focal length wide aperture lens) and an image sensor. The fixed focal length of the lens may correspond to a depth of field area in front of the lens. When an object enters the depth of field area (e.g., sue to a relative motion between the object and the lens) the object representation on the image sensor plane may be in-focus. Objects outside the depth of field area may be out of focus. In-focus representations of objects may be characterized by a greater contrast parameter compared to out of focus representations. One or more images provided by the detection apparatus may be analyzed in order to determine useful information (e.g., an image contrast parameter) of a given image. Based on the image contrast meeting one or more criteria, a detection indication may be produced.

Abstract: A spectral filter is manufactured using a process wherein a first rectangular bar is formed within a first layer made of a first material, said first rectangular bar being made of a second material having a different optical index. The process further includes, in a second layer over the first layer, a second rectangular bar made of the second material. The second rectangular bar is positioned in contact with the first rectangular bar. The second layer is also made of the first material.

Abstract: The present invention provides a liquid crystal display panel of improving color washout, setting different alignment angles in the sub pixel areas of different colors (the included angle between the alignment direction of the liquid crystal molecules and the branch electrode of the pixel electrode). Then, the alignment angle of the red sub pixel area is the largest, and the alignment angle of the green sub pixel area is smaller, and the alignment angle of the blue sub pixel area is smallest. Thus, it is possible to respectively modulate the transmittance-voltage curves and the brightness-voltage curves of the lights of different colors to optimize the white dot chromaticity for satisfying the optical specification and compensate the losing transmittance of the blue light in the panel for improving the color washout problem.
