  • Patent number: 7808322
    Abstract: A system comprises a variable gain amplifier (VGA) that amplifies an input signal with a gain that is based on a gain control signal. A power amplifier receives an output of the VGA. Memory switches between at least two of N output power settings each including a predetermined reference value and a predetermined gain offset value. The memory substantially concurrently changes from the predetermined reference value and the predetermined gain offset value of a prior one of the N output power settings to the predetermined reference value and the predetermined gain offset value of a current one of the N output power settings, where N is an integer greater than one. A gain control adjuster adjusts the gain control signal based on an output of the power amplifier and the predetermined reference value and gain offset value of the current one of the N output power settings.

  • Publication number: 20100245355
    Abstract: A method estimates a 3D pose of a 3D specular object in an environment. In a preprocessing step, a set of pairs of 2D reference images are generated using a 3D model of the object, and a set of poses of the object, wherein each pair of reference images is associated with one of the poses. Then, a pair of 2D input images are acquired of the object. A rough 3D pose of the object is estimated by comparing features in the pair of 2D input images and the features in each pair of 2D reference images using a rough cost function. The rough estimate is refined using a fine cost function.
