Patent ID: 8101244

Claim:
An apparatus for producing a product by dispensing a droplet of liquid on a carrier substrate, the apparatus comprising: a dispensing module for dispensing the droplet onto the carrier substrate; a device for moving the carrier substrate along a first axis of the apparatus; a first camera connected to said dispensing module; a mechanism operably connected to said first camera, wherein said mechanism actuates said first camera to obtain a first image of the droplet while the droplet is in-flight between said dispensing module and the carrier substrate; a processor in operative communication with said first camera, said processor determining an amount of the droplet based upon said first image; and a control system in communication with said device for moving the carrier substrate and said dispensing module, wherein said control system controls said device to move said carrier substrate continuously along said first axis as said first image is being obtained and as said dispensing module dispenses said dosage, and controls said dispensing module to move along said second axis as said dispensing module dispenses the droplet of liquid.
