Abstract
Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light source disposed in or on a housing of a scanner-scale for producing a light beam along an edge of the weigh platter, the light beam being modulated to contain a defined packet of data; a detector for receiving the data-modulated light beam, the detector being disposed in or on the housing; and a processor coupled with the detector for decoding the defined packet of data responsive to the detector receiving the data-modulated light beam. Various indicators for alerting the operator of off-scale detection are also described.
