20100026853 | METHOD AND SYSTEM FOR SYNCHRONIZING A FLASH TO AN IMAGER - A digital camera system synchronizes a flash to an array of image sensing elements. The array of image sensing elements senses an image focused on the array by a lens. The system includes an array controller that implements an electronic rolling shutter to capture the image as a frame. The electronic rolling shutter includes read and reset pointers that the array controller scans through the array to capture integrated photo charges on the image sensing elements to generate the frame. The number of lines between the reset and read pointers defines the integration time of the imager. The system also includes a flash controller that synchronizes the flash to a portion of the frame. When the flash is activated, the camera system reduces the integration time and synchronizes the flash to the scanning of a selected portion of the array. | 02-04-2010 |

20080291333 | Methods, systems and apparatuses for motion detection using auto-focus statistics - Methods, systems and apparatuses for the detection of motion using statistics data already available within an imager, such as sharpness scores or brightness values. The method includes obtaining at least two sets of statistics data for respective image frames which include corresponding windows; initializing a motion counter; determining, for each window, a relative difference value for the particular window; comparing the relative difference value to a first threshold. If the relative difference value is greater than the first threshold, the method increments the motion counter; and determines if there is motion by comparing the value of the motion counter to a second threshold. The motion detection may further take into account the relative importance of certain areas of the image frame. | 11-27-2008 |
20120092737 | METHOD OF FORMING AN IMAGING DEVICE - A method, apparatus, and system that provides a holographic layer as a micro-lens array and/or a color filter array in an imager. The method of writing the holographic layer results in overlapping areas in the hologram for corresponding adjacent pixels in the imager which increases collection of light at the pixels, thereby increasing quantum efficiency. | 04-19-2012 |

The method of writing the holographic layer results in overlapping areas in the hologram for corresponding adjacent pixels in the imager which increases collection of light at the pixels, thereby increasing quantum efficiency. | 12-05-2013 |

20150255977 | SYSTEM AND METHOD FOR AUTOMATICALLY RAMPING DOWN A SUPERCONDUCTING PERSISTENT MAGNET - An apparatus including an electrically conductive coil which produces a magnetic field when an electrical current passes therethrough; a selectively activated persistent current switch connected across the electrically conductive coil; a cryostat having the electrically conductive coil and the persistent current switch disposed therein; an energy dump; at least one sensor which detects an operating parameter of the apparatus and outputs at least one sensor signal in response thereto; and a magnet controller. The magnet controller receives the sensor signal(s) and in response thereto detects whether an operating fault (e.g. a power loss to the compressor of a cryocooler) exists in the apparatus, and when an operating fault is detected, connects the energy dump unit across the electrically conductive coil to transfer energy from the electrically conductive coil to the energy dump unit. The energy dump unit disperses the energy outside of the cryostat. | 09-10-2015 |
