A system for packaging an item with an identifier comprises an identifier adder, a labeler, and a packager. The identifier adder adds one or more types of silica-based tags to an item, wherein each type of silica-based tag has a first signature readable using an optical spectroscopic reader. A label is generated based at least in part on reading the one or more types of silica-based tags of the item using the optical spectroscopic reader. The label includes goods info. The packager includes the label on a package, and wherein the packager includes the item in the package.

System for producing a packaged item with an identifier

A label has a portion that is readable by a human being and a portion that is readable by a machine. The label includes information stored using a spectral content of reflected from a tag. The label is used for authentication.

Item label with a tag

A system for verifying an item in a package using a database comprises a database and a verifier. A package producer provides the database with an identifier for one or more items each of a type, wherein the package producer produces a package, where the package includes the one or more items each of the type with an associated one or more selected tag identifiers that are placed in a location on an item of the one or more items. The verifier verifies the one or more items of the type using 1) the associated one or more selected tag identifiers as detected using a spectral signature or 2) a tag characteristic as detected using an imager, and 3) the identifier retrieved from the database.

System for verifying an item in a package using a database

An item of a type includes one or more selected tag identifiers that are added to the item of the type. The one or more selected tag identifiers have an optical signature based at least in part on a spectral measurement of the one or more selected tag identifiers. A first item spectral measurement of a first item is detected. A first item optical signature is determined based at least in part on the detected first item spectral measurement. The first item is verified as the item of the type in the event that the first item optical signature corresponds to the optical signature of the one or more selected tag identifiers.

System for verifying an item in a package

A sample holder comprises a bottom and one or more arms. The bottom has an initial area for supporting a sample. The one or more arms actuate to move the sample in the initial area to a target area, wherein the one or more arms hold the sample.

Centering holder for optical interrogation

A system verifying an item in a package comprises a package producer and a verifier. The package producer produces a package with a label, wherein the package includes an item each with one or more selected tag identifiers that are placed in a location on the item. The verifier verifies the item using 1) the one or more selected tag identifiers as detected using a spectral measurement or 2) a location or a shape of the one or more selected tag identifiers on the item, and 3) the label as read using a label reader.

A system and method are disclosed for recording information on a phase change medium is disclosed. The method includes irradiating a region of the phase change medium with a first dose of laser energy. A first portion of the region is irradiated with a second dose of laser energy in a manner that causes the first portion of the region irradiated with the second dose of laser energy to be in a different state than a second portion of the region that is not irradiated by the second dose of laser energy.

High density data write strategy

The present invention is a system for reading a CD having a surface with a multiple level data track including a laser, a focusing and positioning system configured in a way which causes the laser to follow the multiple level data track, a detector which converts the light which is reflected from the data track to an electrical signal, a digital signal processing unit configured to receive the electrical signal including a scaling-function generator for determining a plurality of signal windows from the electrical signal, and a multiple level analog to digital converter which determines a data level based on the signal windows and the electrical signal whereby multiple data levels may be read from the CD.
