  • Patent number: 10710853
    Abstract: Systems and methods for operation of a floor conveyor, the floor conveyor including a sensor device, the systems and methods include providing a predetermined detection zone outside at least a section of the circumference of the floor conveyor for detection of foreign objects positioned inside the predetermined detection zone, wherein the predetermined detection zone is arranged to end at a first predetermined distance from a predetermined object. The method further comprises extending the predetermined detection zone with a second predetermined distance within which the predetermined object is expected to be positioned. The method further comprises implementing security measures on the floor conveyor, if the predetermined object is not detected within the extended predetermined detection zone.
