    摘要: A method and apparatus for estimating a rock strength profile of a formation is disclosed. A tool having a testing surface is conveyed into a wellbore in the formation. The testing surface is propelled to impact the formation at a plurality of depths in the wellbore. A measurement of hardness of the formation is obtained from a rebound of the testing surface from the formation at the plurality of depths. The rock strength profile of the formation is estimated using the obtained measurements of hardness at the plurality of depths. A parameter for drilling the wellbore can be affected using the estimated rock strength profile.

    摘要: A device and method for providing an optical guide of a pixel to guide incoming light to/from a photo-conversion device of the pixel to improve the optical crosstalk immunity. The optical guide includes an optically reflecting barrier formed as a trench filled with a material which produces reflection. The trench fill material may have an index of refraction that is less than the index of refraction of the material used for the trench surrounding layers to provide a light reflective structure or the trench fill material may provide a reflection surface.

    摘要: A device and method for providing an optical trench structure for a pixel which guides incoming light onto the photosensor of the pixel. The optical trench structure has an optically reflecting barrier that substantially mitigates optical crosstalk. The optical trench structure is made of low dielectric constant material with an index of refraction that is less than the index of refraction of the material of surrounding layers (e.g., the substrate). This difference in refractive index causes an internal reflection into an optical path existing between a lens and pixel.
