  • Method and apparatus for providing a focus indication for optical imaging of visual codes
    Patent number: 8181878
    Abstract: A method and apparatus for indicating an in-focus or an out-of-focus condition for an imaging device (1, 2) in an optical reading and decoding apparatus (20) for receiving a coded image from a target area (29) on an article or package. In the method of the invention, two beams of light (27, 28) are generated to provide two illuminated aiming marks (32, 33) on the target. An in-focus condition is indicated when the two aiming marks are in a pre-defined spatial relationship relative to each other on the target. The in-focus condition or an out-of-focus condition can be signaled by controlling attributes of aiming marks (32, 33) or by controlling attributes of status indicator LEDs (12) on the apparatus (20) or by controlling an audible sound.

  • Process and arrangement of monitoring the effectiveness of a spray stream
    Patent number: 6438239
    Abstract: A process of monitoring the function of a spray stream, includes the steps of determining a first signal commensurate with noise in proximity of the spray stream when exiting a spray gun, determining a second signal commensurate with noise in an environment further distant to the spray stream, separating from the first and second signals a wanted signal, and analyzing the wanted signal for evaluation of the effectiveness of the spray stream.
