  • Patent number: 7880785
    Abstract: An imager having color sensitivity in any lighting condition is provided by replacing at least one of the green color filtered pixels in a Bayer pattern array with an non-color filtered pixel and providing a different integration period for each color channel. When replacing a color filtered pixel with a non-color filtered pixel, the benefits of both color sensitivity and light sensitivity may be harnessed by providing the color filtered pixels with a longer integration period than the non-color filtered pixels. Color information may be interpolated by performing subtraction logic using non-color and color filter information from adjacent pixels in back-end processing. Integration times for each color channel can be adapted to minimize filter transmission and sensor absorption differences within each frame of data. Temporal displacement of colors of moving objects by having different integration periods may be corrected in back-end processing. Back-end processing may also correct motion blur.

  • Patent number: 6586859
    Abstract: The present invention relates to animated devices that include one or more electroactive polymer transducers. When actuated by electrical energy, an electroactive polymer produces mechanical deflection in one or more directions. This deflection may be used to produce motion of a feature included in an animated device. Electroactive polymer transducers offer customizable shapes and deflections. Combining different ways to configure and constrain a polymer, different ways to arrange active areas on a single polymer, different animated device designs, and different polymer orientations, permits a broad range of animated devices that use an electroactive polymer transducer to produce motion. These animated devices find use in a wide range of animated device applications.
