CPC G01G 19/40 (2013.01) [G01G 19/4144 (2013.01); G01G 21/22 (2013.01); G01V 8/12 (2013.01); G06K 7/1413 (2013.01); G06Q 20/208 (2013.01)] | 17 Claims |
1. A weigh platter assembly for use in a barcode scanner, the weigh platter assembly comprising:
a weigh platter having a surface extending in a first transverse plane, wherein the weigh platter is configured to support an object placed on the surface and the surface has a proximal edge and a lateral edge non-parallel relative to the proximal edge; and
an off-platter detection assembly comprising:
an assembly field-of-view extending from the proximal edge;
a light emission assembly having a light source, the light emission assembly configured to emit a light away from the proximal edge;
a light detection assembly having a light sensor, the light detection assembly configured to detect at least a portion of the light reflected towards the proximal edge; and
a controller in communication with the light detection assembly and configured to prevent a measured weight from being recorded by a host system operatively coupled to the controller and/or provide an alert in response to a value from the light detection assembly falling within a predetermined range,
wherein at least one of (i) the light sensor has a transverse field-of-view angle greater than a transverse field-of-view angle of the assembly field-of-view and the weigh platter assembly further comprises one or more optical elements configured to constrain the transverse field-of-view angle of the light sensor to the transverse field-of-view angle of the assembly field-of-view or (ii) the light source has a field-of-view greater than the assembly field-of-view and the light emission assembly further comprises one or more optical elements configured to constrain the field-of-view of the light source transversely to the assembly field-of-view.
