Barcoded indicators for quality management
First Claim
1. A barcoded indicator operative to provide a machine-readable indication of exceedance of at least one threshold by one or more product quality affecting parameters, said barcoded quality indicator comprising:
- a first barcode;
a second barcode; and
at least one third barcode,each of said first barcode, said second barcode and said at least one third barcode including a machine-readable state and at least two different non-machine-readable states,one of said first barcode, said second barcode and said at least one third barcode being in at least one of said at least two different non-machine-readable states prior to exceedance of said at least one threshold and being in said machine-readable state following exceedance of said at least one threshold.

Abstract
A barcoded indicator operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality affecting parameter, the barcoded indicator including at least a first barcode and at least a second barcode, the at least a second barcode being in a second barcode unreadable state prior to exceedance of the at least one threshold and upon exceedance of the at least one threshold the at least a first barcode becoming unreadable and generally simultaneously the at least a second barcode becoming readable.

4. A quality management system for products comprising:
-
a multiplicity of barcoded indicators each operative to provide a machine-readable indication of exceedance of at least one threshold by one or more product quality affecting parameters, each of said barcoded indicators comprising; a first barcode; a second barcode; and at least one third barcode, each of said first barcode, said second barcode and said at least one third barcode including a machine-readable state and at least two different non-machine-readable states, one of said first barcode, said second barcode and said at least one third barcode being in at least one of said at least two different non-machine-readable states prior to exceedance of said at least one threshold and being in said machine-readable state following exceedance of said at least one threshold; a barcode indicator reader operative to read said barcoded indicators and to provide output indications; and a product type responsive indication interpreter operative to receive said output indications and to provide human sensible, product quality status outputs.
