  • Patent number: 8325012
    Abstract: A method for optimizing the deployment of RFID apparatus, and a RFID deployment optimizer of use thereof are provided. The method includes the steps: A. analyzing the interrogation zone where the RFID apparatus are deployed, B. identifying the readability o RFID tag associated with different sets of placement on a target object inside the interrogation zone, and C. selecting the best deployment alternative based on the analysis result of the interrogation zone attained in the step A and all the readabilities of RFID tag associated with different sets of placement identified in the step B.

  • Patent number: 8055053
    Abstract: The present invention relates to a method of automated process control operation wherein a physical object is directed into a read zone, information stored on an ID Container attached to the physical object is retrieved, physimetric property of the physical object is captured, the retrieved information is processed to provide recorded physimetric property specific to the physical object, the recorded physimetric property and captured physimetric property are passed to an analysis algorithm for comparison, and the results of the comparison are delivered to a controlling device. The results of the comparison will determine whether the physical property will continue to pass through the read zone or require to be rotated by the operator.

  • Publication number: 20100052867
    Abstract: An apparatus for identifying object movement and location with RFID device comprises two RFID gateways constructed by at least one RFID interrogator located inside and outside an entrance of a monitored zone independently, a portable RFID tag carried by the object capable of receiving and responding said signals emitted by said RFID interrogator, and a data processor connected with said RFID gateways capable of receiving said responses to identify said object movement as leaving or entering said entrance and said object location as outside or inside said monitored zone. There is also a corresponding method for identifying object movement and location with RFID device.

  • Publication number: 20080143476
    Abstract: The present invention relates a scanable product made of a physical object and an ID Container, such ID Container possessing on its memory a Unique ID and a stored coded locking mechanism. The stored coded locking mechanism is generated by inputting physimetric property of the physical object and its Unique ID into hash functions to create an unintelligible code. Methods of making such a scanable product, and methods of authenticating a scanable product are also taught.
