  • Patent number: 8465792
    Abstract: A spray monitoring device analyzes images obtained from a beam passing through a spray pattern applying a spray to a substrate, and identifies discontinuities in the image as indicative of a discontinuity in a spray pattern. The spray pattern is produced by a plurality of nozzles spaced apart across the substrate for applying a suitable coating thereto. The beam is produced by a laser, that preferably has a collimator for distributing the beam intensity. The beam is imaged by a camera that provides a constant image to a computers where the scattering of beam light by the spray pattern is processed by image processing software and optionally provided to a user interface for analysis. Discontinuities detected by the user or software indicate faulty spray nozzles and may trigger remedial action.

  • Patent number: 8146814
    Abstract: In general terms, the present invention provides a method of automatically scanning an inventory field to allow the selection of a desired item for retrieval. A camera is positioned in the crane trolley located above the field. The camera continuously performs a scan of the field displaying an image to the operator of the items being scanned. This real-time image allows the operator to distinguish between items scanned in the field. The operator can subsequently choose the desired item triggering the camera system to automatically capture desired information from the item which is in turn communicated to an inventory control system. The camera system mitigates the requirement of a second individual to communicate information between the field and the operator.
