The present invention provides edible film formulations using low viscosity hydrolyzed vegetable gum as a film forming component. In the base station, a counter counts the receivers satisfying the reception criterion, and a divider establishes a reception quality indicator dependent on the number of satisfactory receivers so as in particular to retransmit it via a return channel to the camera so that it can be displayed thereon. The lens assembly sheets are then arranged on holding surfaces defined on a jig. The knowledge base may be coupled to a data structure assembly facility configured to retrieve one or more cross-referenced data structure components from a database.
