Title: Method for color detection in video images
Inventor: CLASSEN BRIAN J
IPC: H04N9/64
Filed: 1999-11-12
Abstract: A method of identifying pixels of a given color in a field of YUV video manipulates color difference signals (R-Y, B-Y) corresponding to defining axes (U,V) of a color space to maximize the video signal in a region of interest of the space, and minimize the signal in all other regions. Additionally, the color difference signal corresponding to one axis may be rotated toward the other axis, or the entire color space may be rotated to bring the region of interest onto or near one of the axes.  The signal gains and rotations may be carried out in the signal processing circuits (52) of a conventional color camera (50) so that only one comparator (90) is needed to detect the target color. After rotation and application of gain, the color difference signal defining the region of interest is compared with a threshold value to determine if a pixel is of the target color. A video camera may be mounted on an agricultural sprayer to detect green weeds on the brown soil, by identifying the green pixels in the image captured while the sprayer travels in the field. A spray material may be released upon the weed, once the weed is detected.

Title: Method for reproducibly forming a predetermined quantum dot structure and device produced using same
Inventor: WILLIAMS ROBIN L
IPC: H01S5/34
Filed: 2001-10-29
Abstract: The present invention relates to a method for reproducibly forming a predetermined quantum dot structure and a device produced using same. A crystal facet of a substrate base is patterned for providing a predetermined portion of the crystal facet for subsequent predetermined crystal growth. A first growth material is deposited for crystallographically growing a predetermined mesa structure on the predetermined portion of the crystal facet. The mesa structure, which is a portion of the quantum dot structure, comprises predetermined low index side facets and a predetermined top surface. A second growth material for forming at least a quantum dot on the mesa structure is then deposited. The number, the lateral dimensions and the location of the at least a quantum dot is determined by the mesa structure. A sufficient amount of the second growth material is deposited such that a sufficient thickness for Straski-Krastinow growth of the second growth material on the top surface of the mesa structure is exceeded.  The at least a quantum dot is embedded by continuing crystal growth on the mesa structure.  The method allows reproducible manufacture of predetermined quantum dot structures such as single photon sources. For example, a covering structure is crystallographically grown in-situ on the mesa structure wherein the covering structure comprises crystal facets forming a mirror. The covering structure then forms together with the mesa structure and a reflector of the substrate base a micro-cavity providing a single photon laser.
