Patent number: 8411507Abstract: Shifts in the apparent charge stored on a floating gate (or other charge storing element) of a non-volatile memory cell can occur because of the coupling of an electric field based on the charge stored in adjacent floating gates (or other adjacent charge storing elements). To compensate for this coupling, the read or programming process for a given memory cell can take into account the programmed state of an adjacent memory cell. To determine whether compensation is needed, a process can be performed that includes sensing information about the programmed state of an adjacent memory cell (e.g., on an adjacent bit line or other location).Type: GrantFiled: August 30, 2012Date of Patent: April 2, 2013Assignee: SanDisk Technologies Inc.Inventor: Yan Li Li

Patent number: 8390731Abstract: A system and method for measuring a border of an image of an object includes setting measurement parameters, selecting a start point, an end point, and a image capture direction, and marking isS=true, moving a CCD lens to a current point, capturing an image by the CCD lens, and obtaining sequential border points of the image. The method further includes determining if the sequential border points are fuzzy, performing an automatic focus function if the sequential border points are fuzzy, or further determining the border of the object has been completely captured if the sequential border points are clear, calculating accurate border points if the border of the object has not been completely captured, and determining a new start point to capture the next image of the object.Type: GrantFiled: August 16, 2012Date of Patent: March 5, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Chih-Kuang Chang, Xian-Yi Chen, Yan-Li Li, Yi-Rong Hong, Li Jiang
