Methods, systems, and apparatus for combining preprinted information together with coded sensor information within a two-dimensional barcode. The sensor information may be of an environmental, physical or biological nature, and records a cumulative change in status of the environmental or biological condition to which the labeled product has been exposed. A sensor dye chemistry is employed that undergoes a continuous chemical or physical state change in response to the occurrence of the environmental condition. The continuous change is between an initial state and an end state causing a change in the color state of the sensor dye embedded within the sensor-augmented two-dimensional barcode, encoding sensor digital information. Sensor information is recovered utilizing the error-correction feature during barcode decoding.

Methods, systems, and apparatus for combining preprinted information together with coded sensor information within a two-dimensional barcode. The sensor information may be of an environmental, physical or biological nature, and records a change in status of the environmental or biological condition to which the labeled product has been exposed. A sensor dye chemistry is employed and when a specified condition of the sensed property occurs it causes a change in the color state of sensor dye modules embedded within the sensor-augmented two-dimensional barcode, encoding sensor digital information. Sensor information is recovered utilizing the error-correction feature during barcode reading.

A sensor-augmented two-dimensional barcode includes a layer provided on a substrate comprising a two-dimensional error-correcting barcode symbol. The bar code symbol further includes a barcode region, an empty region, and a dynamic region. The barcode region includes a plurality of modules in a static color state and the empty region has an area. Additionally, the dynamic region is provided on the substrate and positioned within the area of the empty region. The dynamic region includes a dynamic indicator having a chemistry that is configured, responsive to the occurrence of an environmental condition, to undergo a chemical or physical state change between an initial state and an end state, causing a change in the color state of the dynamic indicator. Additionally, the color state indicates exposure to the environmental condition.

An example disclosed media processing device includes an image processing unit; a first optical registration sensor; and a second optical registration sensor spaced apart from the first optical registration sensor along a first axis by a first distance associated with a gap between media units on a web.

Direct thermal media and registration sensor system and method for use in a color thermal printer

A system having a UHF RFID transceiver is adapted to communicate exclusively with a single electro-magnetically coupled transponder located in a predetermined confined transponder operating region. The system includes a near field coupling device comprising a plurality of lines connected in parallel with an unmatched load. The near field coupling device may be formed, for example on a printed circuit board with a plurality of electrically interconnected traces and a ground plane. The system establishes, at predetermined transceiver power levels, a mutual electro-magnetic coupling which is selective exclusively for a single transponder located in a defined transponder operating region. Also included are methods for selective communication with the transponder in an apparatus such as a printer-encoder.

A system and method of tracking, assigning and releasing biological fluids. The system and method identifies, assigns and releases biological fluid products from controlled storage based on medical criteria supported by the use of RFID technology.

Method and apparatus for identifying and tracking biological fluids using RFID

Provided is a direct thermal media containing a regular repeating pattern of color-forming thermally-imageable stripes printed parallel to the print head element line and a system for using such direct thermal media in color direct thermal printers including an optical registration system optimized for use with this media and an image processing unit that monitors the position of the stripe pattern relative to the print head and synchronizes the start of the printing process. This direct thermal media together with the optical registration system and image processing unit comprise an operative system in that the design of the thermal media, the optical registration system and image processing unit used to control printing are optimized for use with each other. This system may be utilized, for example, in color thermal printers for documents, receipts, tags, tickets or labels.

An authentication method for authenticating an article in a device includes the steps of (a) reading an identification number stored on the article, (b) reading an authentication number stored on the article, (c) determining an input number based at least in part on the identification number, (d) applying an authentication function to the input number to calculate an output number, (e) determining that the article is authentic only if the authentication number corresponds to the output number, and (f) permitting use of the article in the device if the article is authentic, and disabling use of the article in the device if the article is not authentic.
