A coating for an object having identifying indicia disposed thereon. An ink layer contacts at least a portion of the identifying indicia. The ink layer obscures the portion when exposed to light within a predetermined wavelength range, and the ink layer reveals a predetermined area of the portion when exposed to light outside of the predetermined wavelength range.

Ink coatings for identifying objects

Methods and systems of the present invention are directed to clustering RFID-tag readers of a multi-RFID-tag-reader network in order to obtain a set of RFID-tag readers with high probability of detecting an event, but with low probability of collisions and with an acceptable cost. The cost may be determined by any of numerous cost functions of the RFID-tag readers in the set of RFID-tag readers, and may represent a cost in power, long-term reliability, and other such metrics that may be applied to an RFID-tag network.

Clustering methods for radio-frequency-identifier networks

Methods and systems of the present invention employ perturbation techniques for configuring RFID-tag-reader networks in order to achieve increased overall efficiency of a network of RFID-tag readers. According to described embodiments of the present invention, individual RFID-tag readers within a multi-RFID-tag-reader network may be removed or shut down, or RFID-tag readers may be displaced relative to one another, in order to remove interferences between RFID-tag readers and to increase the interrogation efficiency of the multi-RFID-tag-reader network. A method embodiment of the present invention schedules a multi-RFID-tag-reader network as a cycle of power-on/power-off intervals.

A method of identifying a product includes generating a code unique to the product, said code being provided by a multitude of individual identifiers, applying the multitude of the identifiers of the code to the packaging of the product as a pattern to identify the product. The method also involves applying a sub-set of two or more of the multitude of the identifiers of said code to the product, said sub-set of the multitude of the identifiers of the code being applied so they will be presented in the same pattern order as they appear in the pattern order of the multitude of the identifiers of the code applied to the packaging. The product can be identified with a reasonable likelihood of being a genuine product by determining that a presented pattern order of the sub-set of the multitude of the identifiers applied to the product corresponds to a presented pattern order within the multitude of the identifiers applied to the packaging.

Identifying products

A method of authenticating products includes receiving a description of detectable features read from a package. The package includes two or more detectable features, and the detectable features are affixed on the package based on encoded information. Authentication information is provided based on a comparison of the received description to one or more stored package identifiers.

Authenticating products

A method of authenticating a package is described. The method includes receiving a read identifier. The read identifier includes information from multiple modes of information storage on a package. Authentication information is provided based on a comparison of the read identifier and one or more stored identifiers.

Package authentication

A system for distinguishing a package includes a plurality of identifiers, where at least one of the identifiers is intentionally non-functional. The system also includes an identifier indicator that indicates the identity of the at least one of the identifiers that is intentionally non-functional. In addition, the identifier indicator is stored on at least one of the package and a database and is accessible by a user to authenticate the package.

The present invention includes a method and system for dynamically controlling cooling resources in a data center based on the workload of the data center. Accordingly, based on the workload constraints (power consumed, latency, etc.) of the data center, each of a plurality of different types of cooling resources is activated in an optimal fashion. Consequently, a substantial savings in operational costs related to cooling resources is achieved. A first aspect of the present invention is a method for dynamically controlling cooling resources in a data center. The method comprises determining a workload within the data center, determining an amount of heat being generated as a function of the workload and activating each of a plurality of different types of cooling resources within the data center in an optimal fashion based on the amount of heat being generated.

A method and system thereof for reducing the energy consumed when decoding an encoded and synchronized multimedia data stream, wherein the data stream is non-preemptable and subject to precedence constraints. In a client-server environment, the server delivers to the client the stream for decoding. The client has a processor operating on a discrete variable-voltage power supply. Prior to transmitting the stream to the client, the server produces an execution schedule according to the precedence constraints. The server also assigns a voltage setting for each task in the schedule, wherein each task decodes a frame in the stream without preemption. The server transmits the execution schedule and voltage settings to the client with the encoded data stream. The schedule and voltage settings reduce energy consumption by the client while satisfying multimedia timing constraints.
