An improved automatic image capture system for an intelligent mobile device having a camera guides a user to position the camera so only a single image needs to be automatically captured. A trapezoidal view finder on a display of the intelligent mobile device may be used to orient the camera with respect to a target document so there is an appropriate pitch and roll angle between the camera and the target document to avoid shadows caused by the camera or user. Further the user is guided to maximize the occupancy of the view finder with the document so that the document is maximized within the view finder. When all requisite conditions are satisfied, the camera automatically captures the image of the document for post-processing.

Date Oct. 1, 1998A flat fluorescent lamp (1) has a discharge vessel (2) having a base plate (7), a top plate (8) and a frame (9) which are connected to one another in a gas-tight fashion by means of solder (10). Structures resembling conductor tracks function in the interior of the discharge vessel as electrodes (3-6), in the feedthrough region as feedthroughs, and in the external region as external supply leads (13; 14). Flat lamps of the most different sizes can thereby be produced simply in engineering terms and in a fashion capable of effective automation. Moreover, virtually any electrode shapes can be realized, in particular optimized with regard to a uniform luminous density with a reduced drop in luminous density towards the edges of the flat lamp. At least the anodes (5, 6) are covered in each case with a dielectric layer (15). The lamp (1) is preferably operated by means of a pulsed voltage source and serves as background lighting for LCDs, for example in monitors or driver information displays.

An optical clocking signal is shined on the back surface of the silicon substrate. The light has a wavelength long enough so that it penetrates through the silicon substrate to the germanium containing layer. The wavelength is short enough so that the light is absorbed in the germanium containing layer and converted to the electrical clocking signal used for neighboring devices and circuits. The germanium concentration is graded so that minority carriers are quickly swept across junctions of the diodes and collected.
