  • Method for detecting objects and light barrier grid
    Patent number: 6958465
    Abstract: A method for monitoring two or more movable objects in a monitoring region. A substantially horizontal light barrier grid having a plurality of parallel light barriers monitors the region. To permit a plurality of objects to simultaneously move in the monitored region without deactivating the monitoring function of the system, the system controls an entry area for the objects, the size of the objects as well as the distance between the objects to ascertain that predetermined criteria therefor are met. If one or more of these criteria is not met, a control signal is generated which can be used, for example, to deactivate the machinery and/or prevent access to the monitored region.
