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 identifier made using a silicon film fragment. The silicon film has a varying optical index of refraction. The varying optical index of refraction reflects one or more spectral peaks when illuminated with light. The one or more spectral peaks includes a reference peak. The silicon film is fragmented to generate the silicon film fragment.

Labeling and authenticating using a microtag

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

An identifier made using a silicon film. The silicon film has a varying optical index of refraction. The varying optical index of refraction reflects one or more spectral peaks when illuminated with light. The one or more spectral peaks includes a reference peak. The silicon film is fragmented and then oxidized.

A system for decoding energy peaks of an identifier includes an interface and a processor. The interface is configured to receive a reference peak position associated with an identifier, wherein the identifier comprises a rugate microtag, and receive a set of data pattern peak positions associated with the identifier. The processor is configured to determine a set of adjusted data pattern peak positions based on the reference peak position.

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 for encoding energy peaks of an identifier comprises an encoder. The encoder is configured to define a readable spectral range of an identifier. The identifier comprises a rugate microtag. The encoder is configured to divide the readable spectral range into a plurality of bins. The encoder is configured to encode in a center of a bin near one end of the readable spectral range a reference peak. The encoder is configured to encode in a center of each of a set of bins a set of peaks of a data pattern within the readable spectral range.

Described embodiments provide a multi-port memory system that has a plurality of memory banks and an equal number of mapping memory banks, each one of the data memory banks corresponding to one of the mapping memory banks. The multi-port memory reads, from one of the mapping memory banks selected by a read logical bank number, a read physical bank number identifying which one of the data memory banks data is to be read. The memory system also calculates, from at least one physical bank number read from the mapping memory banks other than the mapping memory bank selected by the read logical bank number, a write physical bank number indicating which one of the data memory banks is to be written. The calculation uses a hash of the physical bank numbers, such as by using an Exclusive-OR. This arrangement allows for simultaneous read/write access of the memory with fixed latency.

Two-port memory capable of simultaneous read and write

A storage device provides single-port read multiple-port write functionality and includes first and second memory arrays and a controller. The first memory array includes first and second single-port memory cells. The second single-port memory cell stores data in response to a memory access conflict associated with the first single-port memory cell. The second memory array stores location information associated with data stored in the first and second single-port memory cells. The controller is operatively coupled to the first and second memory arrays, and resolves the memory access conflict by determining locations to store data in the first and second single-port memory cells to thereby avoid a collision between concurrent memory accesses to the first single-port memory cell in response to the memory access conflict. The controller determines locations to store data in the first and second single-port memory cells based on the location information.

Single-port read multiple-port write storage device using single-port memory cells

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 measurement or 2) a tag characteristic as detected using an imager, and 3) the identifier retrieved from the database.
