Abstract

A quality management system for products including a multiplicity of barcoded quality indicators, a barcode indicator reader and a product type responsive indication interpreter, each of the barcoded quality indicators including a first barcode including at least one first colorable area, the first barcode being machine-readable before exceedance of the at least one time and temperature threshold, at least a second barcode including at least one second colorable area, the second barcode not being machine-readable before exceedance of the at least one time and temperature threshold, a coloring agent located at a first location on the indicator and a coloring agent pathway operative to allow the coloring agent to move, from the first location to the first and second colorable areas simultaneously thereby causing the first barcode to become unreadable and at the same time causing the second barcode to become machine-readable.

Claims

1. A barcoded quality indicator, operative to provide a machine-readable indication of exceedance of at least one threshold, comprising:

at least one barcode, said at least one barcode including;

a first machine-readable state prior to actuation thereof;

a second machine-readable state following actuation thereof and prior to exceedance of said at least one threshold; and

at least one third machine-readable state following actuation thereof and subsequent exceedance of said at least one threshold; and

a pull strip, where removal of said pull strip actuates said indicator.

2. A barcoded quality indicator according to claim 1 and wherein said first machine-readable state is different from said second machine-readable state.

3. A quality management system for products comprising:

a multiplicity of barcoded quality indicators each operative to provide a machine-readable indication of exceedance of at least one threshold, each of said indicators comprising;

at least one barcode, said at least one barcode including;

a first machine-readable state prior to actuation thereof;

a second machine-readable state following actuation thereof and prior to exceedance of said at least one threshold; and

at least one third machine-readable state following actuation thereof and subsequent exceedance of said at least one threshold; and

a pull strip, where removal of said pull strip actuates said indicator;

a barcode indicator reader operative to read said barcoded quality 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.

4. A method for providing quality management for products comprising:

employing a multiplicity of barcoded quality indicators each operative to provide a machine-readable indication of exceedance of at least one threshold, each of said indicators comprising;

at least one barcode, said at least one barcode including;

a first machine-readable state prior to actuation thereof;

a second machine-readable state following actuation thereof and prior to exceedance of said at least one threshold; and

at least one third machine-readable state following actuation thereof and subsequent exceedance of said at least one threshold; and

a pull strip, where removal of said pull strip actuates said indicator;

reading said barcoded quality indicators to provide output indications;

receiving said output indications; and

interpreting said output indications to provide human sensible, product quality status outputs.
