Patent number: 8552313Abstract: Systems and methods are provided for reducing erroneous weighing of items by detecting items extending beyond a peripheral edge of a weigh platter associated with a data reader. For example, in response to a weigh request a scale guard module acquires data indicative of whether an item extends between the weigh platter and another surface, compares the acquired data to reference data, and based on the comparison, determines whether an item extends off the weigh platter and thus on to another surface. The scale guard module may utilize non-electromagnetic compression waves, radio waves, a portion of a data reader's scan field to scan a set of patterns extending along at least one edge of the weigh platter, an imaging based scanner to capture an image of at least one edge of the weigh platter, light beams extending along at least one edge of the weigh platter, or any combination thereof.Type: GrantFiled: December 9, 2009Date of Patent: October 8, 2013Assignee: Datalogic ADC, Inc.Inventors: Charles Forrister Atwater, Alexander M.
