Patent number: 9081725Abstract: In a method for protecting digital information, a processor converts a protected address range into a plurality of address blocks of a storage device based on a preset conversion unit, and generates an address block rearranging rule using the address blocks as a parameter. When it is desired to load data into a space of an address batch of the protected address range, the processor converts the address batch into a plurality of address blocks based on the conversion unit, locates rearranged addresses of the address blocks in the protected address range according to the address block rearranging rule, and loads the data into spaces of the rearranged addresses.Type: GrantFiled: November 4, 2013Date of Patent: July 14, 2015Assignee: SHANSUN TECHNOLOGY COMPANYInventors: Jing-Shiun Lai, Ling-Ying Nain, Po-Hsu Lin, Sheng-Kai Lin

Patent number: 5826123Abstract: A camera includes a film cartridge mounting chamber which has a bottom film cartridge opening for loading a small film cartridge and a rear film cartridge opening for loading a large film cartridge, a back cover for closing the rear film cartridge opening, and a bottom cover for closing the bottom film cartridge opening. A lower spindle member is mounted on the bottom cover for holding the bottom of a cartridge spool of the loaded film cartridge. An upper spindle member is mounted on the top of the cartridge mounting chamber for holding a top of the cartridge spool of the loaded film cartridge. A first elastic clamping member is mounted inside the cartridge mounting chamber for applying an axial clamping force on the top of the loaded film cartridge. A second elastic clamping member is mounted inside the cartridge mounting chamber for applying a lateral clamping force on the periphery of the loaded film cartridge.Type: GrantFiled: February 6, 1997Date of Patent: October 20, 1998Assignee: Shansun Technology Company Ltd.Inventor: Jing-Shiun Lai

Patent number: 5752118Abstract: A camera has a cartridge mounting chamber which receives a film cartridge with a cartridge spool, a film exit, and a light-intercepting door. The camera includes a spindle for holding the cartridge spool, a drive mechanism for rotating the spindle in a first direction to feed the film during the photographing operation and in a second direction to wind up the film after completing the photographing operation. The drive mechanism includes a sun gear, a first planetary gear and a second planetary gear engaging the sun gear, and a planetary carrier holding the first and second planetary gears and disposed coaxially with the sun gear. The sun gear is rotatable in two directions for turning the planetary carrier between a first position, in which the first planetary gear drives the spindle in the first direction, and a second position in which the second planetary gear drives the spindle in the second direction.Type: GrantFiled: February 6, 1997Date of Patent: May 12, 1998Assignee: Shansun Technology Company.

Patent number: 5752116Abstract: A camera includes a cartridge mounting chamber, a film take-up chamber, a photographing unit provided between the cartridge mounting chamber and the film take-up chamber. The photographing unit includes a lens housing having a front housing portion holding a lens and a rear housing portion defining a diverging light passage, and a screen adjustment frame having an opening and a frame part confining the opening. The frame part is movable rearward and forward along a direction of the light passing through the diverging light passage for confining the light to pass through the opening. The camera has a device for moving the screen adjustment frame responsive to loading of a film cartridge in the cartridge mounting chamber.Type: GrantFiled: February 6, 1997Date of Patent: May 12, 1998Assignee: Shansun Technology Company, Ltd.Inventor: Jing-Shiun Lai
