  • Patent number: 7593794
    Abstract: A method and apparatus are described for controlling the attitude of a vehicle in a space having at least two opposed viewable regions, each region being viewed by a respective first sensor for sensing a first frequency band of electromagnetic radiation and a respective second sensor for sensing a second frequency band of electromagnetic radiation, wherein respective first and second data sets from the first and second sensors for each regions are produced, these second data sets are subsequently modified and combined with the first data sets to form respective third data sets for each region. The attitude of the vehicle is then adjusted until the third data sets are substantially equal.

  • Publication number: 20070175213
    Abstract: A controller (44) for a SMA actuator (2) includes an electgric power source (46) for applying an electric current through an SMA element (8), a sensor (48) to detect change in an electric resistance of the element (8); and a regulator (50) for controlling the magnitude of the applied electric current. The regulator (50) applies a first current above a safe limit current for the element (8) until a selected change in the electric resistance is detected and applies a second current less than the first current after the change is detected.

  • Patent number: 7251381
    Abstract: A single-mode optical device, including a first region, and a second region laterally disposed about the first region, and including an absorbing layer and an isolation layer between the absorbing layer and the first region, wherein the thickness of the isolation layer is selected to control optical loss from the first region to the absorbing layer in the second region and thereby to attenuate one or more high order lateral optical modes of the device. The one or more high order lateral optical modes are attenuated relative to the fundamental lateral mode to provide the device with a high kink power. The device can be a 980 nm ridge diode laser where the thickness of an oxide insulating layer around the ridge is selected to control optical losses into a gold contact layer and thereby attenuate the first order lateral mode, providing the laser with a kink power of at least about 250 mW.

  • Publication number: 20070040848
    Abstract: A fractal generation process, including: (i) randomly selecting images from a set of V>1 input images; (ii) selecting transformation functions from a set of transformation functions; (iii) generating transformed images by applying the selected transformation functions to the selected images; and (iv) generating an output image by combining the transformed images. Steps (i) to (iv) can be repeated to generate a set of V output images, and the entire sequence can be repeated using the set of V output images as a new set of V input images to generate a new set of output images. After a sufficient number of iterations, the new set of output images is substantially independent of the first set of input images used in the process. The resulting images represent V-variable fractals.
