Systems and methods of alternate operation for a scanner-scale having an item overhang detection system
First Claim
1. A scanner-scale system for passing items to be read through a read zone of the scanner-scale, comprisingan item identification system operable for obtaining item identification data of an item as it is passed through the read zone;
- a weigh platter;
an item overhang detection system operable for providing an output upon sensing that an item overhangs beyond an edge of the weigh platter, wherein the overhang detection system is operable to both (1) reduce erroneous weighing upon sensing that an item overhangs beyond an edge of the weigh platter and (2) initiate an alternate function of the scanner-scale independent of weighing operation;
wherein the alternate function comprises the item identification system being operable to use output from the item overhang detection system for detection of exit and entry of items for allowing successful reading of multiple items having the same identification data using a double-read timer and without requiring expiration of the double-read timer.

Abstract
In a scanner-scale system for passing items through a read zone over a weigh platter of the scanner-scale, the system including an item overhang detection system operable for providing an output upon sensing that an item overhangs beyond an edge of the weigh platter, systems and methods are disclosed for using output from the item overhang detection system to both (1) reduce erroneous weighing upon sensing that an item overhangs beyond an edge of the weigh platter (such as by alerting the operator that an item overhang condition has been detected and thus prompting the operator to reposition the item so as to be fully on scale) and (2) initiate an alternate function of the scanner-scale independent of weighing operation.

1. A scanner-scale system for passing items to be read through a read zone of the scanner-scale, comprising
an item identification system operable for obtaining item identification data of an item as it is passed through the read zone; -
a weigh platter; an item overhang detection system operable for providing an output upon sensing that an item overhangs beyond an edge of the weigh platter, wherein the overhang detection system is operable to both (1) reduce erroneous weighing upon sensing that an item overhangs beyond an edge of the weigh platter and (2) initiate an alternate function of the scanner-scale independent of weighing operation; wherein the alternate function comprises the item identification system being operable to use output from the item overhang detection system for detection of exit and entry of items for allowing successful reading of multiple items having the same identification data using a double-read timer and without requiring expiration of the double-read timer. - View Dependent Claims (2)

3. A scanner-scale system for passing items to be read through a read zone of the scanner-scale, comprising
an item identification system operable for obtaining item identification data of an item as it is passed through the read zone; -
a weigh platter; overhang detection means for sensing that an item overhangs beyond an edge of the weigh platter; a controller operable to both (1) reduce erroneous weighing upon the overhang detection means sensing that an item overhangs beyond an edge of the weigh platter and (2) initiate an alternate function of the scanner-scale independent of weighing operation; wherein the alternate function comprises the item identification system being operable to use output from the item overhang detection system for detection of exit and entry of items for successfully reading multiple items having the same identification data using a double-read timer and without requiring expiration of the double-read timer.

4. A method of operating a scanner-scale, comprising the steps of
passing items through a read zone over a weigh platter of the scanner-scale; -
obtaining item identification data of an item as it is passed through the read zone; providing the scanner-scale with an item overhang detection system, wherein the overhang detection system is operable for providing an output upon sensing that an item overhangs beyond an edge of the weigh platter; during weighing operation, using the output from the item overhang detection system to reduce erroneous weighing upon sensing that an item overhangs beyond an edge of the weigh platter; using output from the item overhang detection system for an alternate function of the scanner-scale independent of weighing operation, wherein the alternate function comprises using output from the item overhang detection system for detection of exit and entry of items from the read zone to allow reading of consecutive items having the same code using a double-read timer and without requiring expiration of the double-read timer. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
