Abstract: A personalized sticker is manufactured by first creating a plurality of copies of a personalized image, with each copy differing in size, and then interlacing the copies to form an interlaced personalized image. The interlaced personalized image is filmed and the film is utilized to print the interlaced personalized image on a sheet of paper. A lenticular tense corresponding to the interlacing of the interlaced personalized image is then formed on a surface of a plastic laminate opposite the sheet of paper. The sheet of paper is removed and the personalized image is transferred to the plastic laminate. A protective backing is next applied to the interlaced personalized image opposite the lenticular lense, which is in turn attached to a double-sided adhesive sheet for later use.

Title: Battery having a built-in controller
Inventor: NEBRIGIC DRAGAN DANILO
IPC: G01R31/36
Filed: 1999-04-01
Abstract: A multiple-cell battery having a built-in controller is disclosed that extends the run time of the battery. The controller may extend the run time of the battery, for example, by converting the cell voltage to an output voltage that is greater than a cut-off voltage of an electronic device, by converting the cell voltage to an output voltage that is less than the nominal voltage of the electrochemical cell of the battery, or by protecting the electrochemical cell from current peaks. The controller may also include a ground bias circuit that provides a virtual ground so that a converter may operate at lower cell voltages. The battery may be a single-cell battery, a universal single-cell battery, a multiple-cell battery or a multiple-cell hybrid battery. The individual cells of the multiple-cell battery may be connected in series or parallel.      In addition, the individual cells may have a controller in each cell that is capable of performing one or more functions to extend the run time of the cell.
