Abstract: An image sensor may have an array of image sensor pixels arranged in unit pixel cells each having at least one modified clear image pixel. Each modified clear image pixel may include a modified clear color filter element formed from a transparent material such as an oxide material that is modified with a colored pigment or colored dye such as yellow pigment. Each unit pixel cell may include one or more color pixels of other colors such as red pixels, blue pixels, and green pixels. Image signals such as yellow image signals from the modified clear pixels may be processed along with other color image signals such as red image signals and blue image signals to generate standard red, green, and blue image data. Image processing operations may include chroma demosaicing or point filtering of the image signals from the modified clear image pixels.

Abstract: An image sensor may have an array of image sensor pixels having varying light collecting areas. The light collecting area of each image pixel may vary with respect to other image pixels due to varied microlens sizes and varied color filter element sizes throughout the array. The light collecting area may vary within unit pixel cells and the variability of the light collecting areas of pixels within each pixel cell may depend on the location of the pixel cell in the pixel array. Each unit pixel cell may include at least one clear pixel having a light collecting area that is smaller than the light collecting areas of other single color pixels in the unit pixel cell.

Abstract: A process for making an improved bulk catalyst having a Group VIII metal, such catalyst being useful in producing H.sub.2 O.sub.2 from H.sub.2 and O.sub.2 and/or in producing H.sub.2 from water. The method incorporates the Group VIII metal within the "pillars" of the porous catalyst, without leaving a significant amount of the Group VIII metal on or near the outside surface of the catalyst, by hydrothermal incorporation of the Group VIII metal into the porous pillars.

Abstract: A method for the production of hydrogen peroxide from a source of hydrogen and oxygen in the presence of a dispersion of a catalyst in an organic reaction medium, the catalyst being composed of inert particles of between 1 and 100 microns, the particles having coated thereon about three to ten layers of a zirconium or hafnium complex, the organic reaction medium having a pH of less than about 3 and composed of at least 50% of a lower alkyl alcohol, a lower alkyl ketone or a mixture thereof, water and a mineral acid.
