摘要： An optical system for the tracking or verification of items, having an energy source (e.g., an illumination source), selectively producing a specific wavelength (or small set of wavelengths, such as a spectrum) of energy matched with a material sensitive to that illumination. When the material is subjected to the energy source, it emits a wavelength of energy which is then sensed by a detector.

摘要： An amplifier circuit includes a circuit input, and a circuit output. An inverter, including first and second MOS transistors is connected between first and second supply voltages, and has an inverter input connected to the circuit input, and an inverter output, which provides an inverter output current corresponding to a circuit input voltage. A first resistive element comprises a third MOS transistor and a fourth MOS transistor of opposite conductivity types, and each having their gate and drain terminals connected to the inverter output and the circuit output, and having their respective source terminals connected to respective ones of the first and second supply voltages. A second resistive element includes a fifth MOS transistor and a sixth MOS transistor of opposite conductivity types, and each having its drain-source path connected between the circuit output and the circuit input, and having its gate connected to a respective voltage source.

摘要： A print media has a visible image and a plurality of invisible encodements comprising data printed over it in a hierarchy order, wherein the encodement of the highest order represents a replacement or edited version of the data of lower order encodements. Apparatus and methods provide effectively editing of an existing invisible encodement printed on media with a material sensitive to a first light wavelength by printing an edited or replacement encodement over it with a material sensitive to a second light wavelength of higher order in the hierarchy. Apparatus and methods also provide for selectively reading the highest order encodement, all of the encodements or selected ones of the encodements.

摘要： The present invention relates to an optical reader that includes a color imaging assembly that generates color imaging data. An image analysis circuit determines if the acquired image should be characterized as a color photograph or as including a graphical symbol. A processing circuit processes the imaging data based on the image analysis circuit's determination of whether the image is a graphical symbol or a color photograph. The present invention allows a user to acquire and process both color images and graphical symbols, such as bar codes, text, OCR symbols or signatures. The optical reader of the present invention is also configured to associate an acquired image with at least one other acquired image.
