  • Image capturing apparatus and method for capturing images of objects
    Patent number: 9049373
    Abstract: A method captures images of objects using an image capturing apparatus. The method obtains x-coordinate values, y-coordinate values, and z-coordinate values of the accelerations of a camera device sensed by a gravity sensor in a default time interval, calculates three-dimensional coordinate differences according to the obtained x-coordinate, y-coordinate, and z-coordinate values, and determines whether the three-dimensional coordinate differences are less than corresponding predefined thresholds. If at least one coordinate difference is not less than a corresponding predefined threshold, the method delays a period of time to obtain the x-coordinate, y-coordinate, and the z-coordinate values in a next default time interval. If all the three-dimensional coordinate differences are less than the corresponding predefined thresholds, the method controls the camera device to capture images of the subject object.

  • Enhanced scanner throughput system and method
    Patent number: 8906599
    Abstract: A method and system to improve scanner throughput is provided. An image from a reticle is projected onto a substrate using a continuous linear scanning procedure in which an entire column of die or cells of die is scanned continuously, i.e. without stepping to a different location. Each scan includes translating a substrate with respect to a fixed beam. While the substrate is translated, the reticle is also translated. When a first die or cell of die is projected onto the substrate, the reticle translates along a direction opposite the scan direction and as the scan continues along the same direction, the reticle then translates in the opposite direction of the substrate thereby forming an inverted pattern on the next die or cell. The time associated with exposing the substrate is minimized as the stepping operation only occurs after a complete column of cells is scanned.

  • Computing device and method for controlling access to driver programs
    Patent number: 8850228
    Abstract: A computing device and a method for controlling access to driver programs obtains a first system time at the time that an application uses a CTL_CODE to access a driver program. The first system time and the CTL_CODE is encrypted to generate an encrypted CTL_CODE which is then sent to the driver program. The encrypted CTL_CODE is decrypted to obtain the first system time and the CTL_CODE therein. A second system time at the time that the driver program receives the encrypted CTL_CODE is obtained and compared with the first system time. Access to the driver program is allowed if a difference between the first system time and the second system time falls within a predetermined range, and access to the driver program is forbidden if the difference is beyond the predetermined range.
