Patent ID: 7094305

Claim:
A method for producing batches of micro particles, comprising the following steps: a) creating a photographic film having a plurality of codes marked thereon as well as markings for aligning a laser for cutting wherein the photographic film is created by creating a spreadsheet on a computer, said spreadsheet having a plurality of cells, and each cell containing one code, converting said spreadsheet to a printable file, and printing said file onto said film; b) placing said film on a support layer; c) cutting the film by means of a laser device according to said aligning markings on said film to define a plurality of microparticles, each microparticle containing said code wherein said film is cut by aligning the laser on the film using count marks on each frame of the film to locate the frame under the laser and blacking out cells at preset positions so that a vision system controlling the laser can detect said blacked out cells and make a final adjustment to the laser so that the laser cuts precisely around each code; and d) removing the micro particles from the support.
