  • Patent number: 12631843
    Abstract: An apparatus, system, and computer-implemented method that correct for thermal drift in one or more optical elements in an optical device and maintain high precision accuracy of the optical device during extreme temperature changes. The apparatus includes an optical device having an optical element configured to direct or reflect a light beam, a pivot support configured to hold a portion of the optical element and facilitate motion of the optical element in multidimensional space, a controller configured to determine a displacement of the optical element due to thermal drift and generate an actuator drive signal based on the amount of the displacement, and an actuator configured to receive the actuator drive signal and counteract the thermal drift by moving, in cooperation with the pivot support and in response to the actuator drive signal, the optical element by an inverse amount and direction of the displacement of the optical element.

  • Patent number: 8332789
    Abstract: A method may include receiving an input from an optimization control that indicates a value along a scale, wherein the value is indicative of a design tradeoff between at least optimization for a first parameter of an electrical design and an optimization for a second parameter of the electrical design, wherein the value places an emphasis on the first parameter and an emphasis on the second parameter such that when the value on the scale is closer to the first parameter a larger emphasis is placed on the first parameter of the electrical design and when the value on the scale is closer to the second parameter a larger emphasis is placed on the second parameter of the electrical design. The method may further include choosing components for the electrical design based on the value indicated using the optimization control, the emphases affecting the components selected for the electrical design.
