摘要： A system and method for minimizing negotiation of the passive RFID tags (T1-T6). Each tag (T1-T6) stores an acknowledgement flag after being ready by the reader (104) and goes into a dormant state. The reader (104) is able to address all tags (T1-T6) or address the unread tags (T1-T6). Each tag (T1-T6) may clear its acknowledgement flag when a signal is received by the reader (104). The tags (T1-T6) that have not been acknowledge will continue to communicate with the reader (104).

摘要： A system and method is provided for minimizing the unintended re-negotiation of RFID tags in a population of tags (102). Each tag stores a confirmed read flag (334) to indicate whether the tag has been previously read. During subsequent interrogations of the tag population, the reader (104) has the capability to address all tags in a tag population or to address only unread tags. When addressing all tags, the reader sends a symbol causing all tags to ignore their confirmed read flag value. Each tag (102) may also clear its confirmed read flag (334) when this symbol is received. When addressing only unread tags, the reader sends a symbol causing each tag (102) to evaluate its confirmed read flag value. Those tags that have a confirmed read flag value indicating "read" will enter dormant state and will not be re-negotiated. Those tags that have a confirmed read flag value indicating "not read" will continue to communicate with the reader.

摘要： Methods and systems for the negotiation of a population of RFID tags with improved security is provided. In one aspect, tags are singulated without using information that directly identifies the tags in the tag population. A key is generated to identify each RFID tag of the population of RFID tags. The generated key does not include bits identifying an item with which the particular RFID tag is associated. An algorithm is operated to identify one or more tags in the population of RFIDs tags using the generated keys. In another aspect, frequency hopping and/or spread spectrum techniques are used to provide improved security while negotiating tags. In another aspect, the reader causes the tags to scroll series of bits back to the reader for each bit sent to the tags to provide improved security.

摘要： Methods and systems for the negotiation of a population of RFID tags (120) with improved security is provided. In one aspect, a binary traversal is performed to singulate tags without using information that directly identifies the tags (102) in the tag population. A key is generated to identify each RFID tag of the population of RFID tags. The generated key does not include bits identifying an item with which the particular RFID tag is associated. A binary tree algorithm is operated to identify one or more tags in the population of RFIDs tags using the generated keys. In another aspect, frequency hopping and/or spread spectrum techniques are used to provide improved security while negotiating tags. In another aspect, the reader (104) causes the tags to scroll series of bits back to the reader for each bit sent to the tags to provide improved security.

摘要： Methods, systems and apparatuses for RFID readers forming a reader network are described. In an aspect of the present invention, a plurality of RFID readers are configured to interrogate tags. Furthermore, the readers are configured to communicate with one another. Each reader includes a network interface module and an optimization module to receive and process statistical data obtained from other readers in the network. A set of operational rules for the environment is indicated, and tag interrogations are optimized according to the rules. Readers may communicate according to a "Listen Before Talk" (LBT) protocol to avoid undesirable interference. Individual readers are capable of dynamically establishing and joining a network, and leaving the network in a self-configured and semi-autonomous or autonomous manner.

摘要： The present invention is directed to locating and imaging with a swallowable sensor device disposed in a patient. The swallowable sensor device transmits an acoustic signal from inside a patient' s body. A plurality of sensing elements receive the acoustic signal. A computation module determines a location of the swallowable sensor device with respect to the plurality of sensing elements based on the acoustic signal received by at least a subset of the plurality of sensing elements. A three- dimensional image of an interior portion of the patient can also be formed based on the received acoustic signal. The three-dimensional image may be formed by stereoscopically displaying two two-dimensional images of the interior portion, wherein the two two-dimensional images correspond to the swallowable sensor device being located at two different locations. Alternatively, the three-dimensional image may be formed by Computing three-dimensional pixels of the interior portion.

摘要： Methods and apparatuses are described for optimizing an interrogation of a radio frequency identification (RFID) tag population. An RFID reader sets an initial number of time slots used to interrogate a population of tags. The reader does not previously know the size of the tag population. The reader monitors responses of tags for one or more time slots of an interrogation round to collect statistical data, estimates a number of tags in the population based on the statistical data, and determines a new number of time slots based on the estimated number of tags. The reader adjusts the number of time slots accordingly for a subsequent interrogation round. The reader may repeat this process as needed to converge closer to the actual number of tags in the population, and an acceptable number of time slots, to enhance an efficiency of the process of interrogating the tag population.
