  • Constant sensing current for reading resistive memory
    Patent number: 9502088
    Abstract: Systems and methods relate to providing a constant sensing current for reading a resistive memory element. A load voltage generator provides a load voltage based on a current mirror configured to supply a constant current that is invariant with process-voltage-temperature variations. A data voltage is generated based on the generated load voltage, by passing a sensing current mirrored from the constant current, through the resistive memory element. A reference voltage is generated, also based on the generated load voltage and by passing reference current mirrored from the constant current, through reference cells. A logical value stored in the resistive memory element is determined based on a comparison of the data voltage and the reference voltage, where the determination is free from effects of process-voltage-temperature variations.

  • Image capture for later refocusing or focus-manipulation
    Patent number: 9501834
    Abstract: A system, method, and computer program product for capturing images for later refocusing. Embodiments estimate a distance map for a scene, determine a number of principal depths, capture a set of images, with each image focused at one of the principal depths, and process captured images to produce an output image. The scene is divided into regions, and the depth map represents region depths corresponding to a particular focus step. Entries having a specific focus step value are placed into a histogram, and depths having the most entries are selected as the principal depths. Embodiments may also identify scene areas having important objects and include different important object depths in the principal depths. Captured images may be selected according to user input, aligned, and then combined using blending functions that favor only scene regions that are focused in particular captured images.

  • Area efficient field effect device
    Patent number: 9502312
    Abstract: A novel semiconductor transistor is presented. The semiconductor structure has a gate region forming a channel with repetitive patterns in the direction perpendicular to the current flow, so that the portion of its channel that is not strictly planar contributes to a significant reduction of the silicon area occupied by the device. It offers the advantage of lower on-resistance for the same silicon area while improving on its dynamic performances. The additional cost to shape the channel region of the device in periodic repetitive patterns is minimum, which makes the present invention easy to implement in any conventional CMOS process technology and very cost effective.
