    • A location localization method and system. The method includes transmitting by an RFID tag reader, a request for locating a passive RFID tag in a facility. The RFID tag reader receives from a first group of active RFID tags, a first date/time associated with first data. The RFID tag reader transmits to the first group of active RFID tags, a request for retrieving the first data. The first data comprises distances between each active RFID tag of the first group and the passive RFID tag. The RFID tag reader receives the first data. The RFID tag reader receives a map of the facility and locations on the map for the first group of active RFID tags. The RFID tag reader determines a location within the facility for the passive RFID tag based on the first data, the map, and the locations on the map. The RFID tag reader transmits the first location to a user.

    • A method and RFID tag for locating RFID tags. A passive RFID tag A receives a polling command transmitted from a RFID reader and addressed to another passive RFID tag B. The RFID tag A determines that the polling command is not addressed to the RFID tag A and consequently, at time t1, switches the REID tag A to a catching mode for catching echos from other tags. The RFID tag A receives at time t3>t1 an echo of a message sent by the RFID tag B to the RFID reader. The RFID tag A determines a distance (D.t2t) between the RFID tag A and the RFID tag B based on t3 minus t1. The distance D.t2t does not exceed a specified radius limit and the identification of the RFID tag B and the distance D.t2t are stored in a database within the RFID tag A.
    • 一种用于定位RFID标签的方法和RFID标签。 无源RFID标签A接收从RFID读取器发送并寻址到另一个无源RFID标签B的轮询命令.RID标签A确定轮询命令不是寻址到RFID标签A,因此在时间t1切换REID 将A标记为捕捉模式,以捕捉其他标签的回声。 RFID标签A在时间t3> t1处接收由RFID标签B发送到RFID读取器的消息的回波。 RFID标签A基于t3减去t1来确定RFID标签A和RFID标签B之间的距离(D.t2t)。 距离D.t2t不超过指定的半径限制,RFID标签B的标识和距离D.t2t存储在RFID标签A内的数据库中。

    • A method and system for localizing an object among a set of objects, each equipped with an improved RFID tag. The tag includes an RFID chip, an antenna, a visual indicator, an AC/DC converter, and at least a pair of conductive surfaces adapted for receiving power from an external source and for powering the electronic chip according to capacitive coupling. Each conductive surface of the pair is designed to form the half of a capacitor, the capacitor being formed when the electronic tag and a similar electronic tag are attached to a neighboring adjacent object. To localize an object, an RFID reader is used, fed with the identifier of the object to be localized. All the capacitively coupled RFID, in the RFID reader range, receive a reading trigger that carries the identifier. The RFID tag compares the received identifier with its own identifier and if they match, then the capacitively coupled RFID reacts by providing a visual indicator; otherwise, if they do not match, the capacitively coupled RFID does not react.
    • 一种用于在一组对象中定位对象的方法和系统,每个对象配备有改进的RFID标签。 该标签包括RFID芯片,天线,视觉指示器,AC / DC转换器,以及适于从外部源接收功率并根据电容耦合对电子芯片供电的至少一对导电表面。 该对的每个导电表面被设计成形成电容器的一半,当电子标签和类似的电子标签附接到相邻的相邻物体时,形成电容器。 为了本地化对象,使用RFID读取器,馈送要定位的对象的标识符。 在RFID读取器范围内的所有电容耦合的RFID都接收携带标识符的读取触发器。 RFID标签将接收到的标识符与其自己的标识符进行比较,并且如果它们匹配,则电容耦合的RFID通过提供视觉指示器来进行反应; 否则,如果它们不匹配,则电容耦合RFID不起作用。

    • A method for synchronizing communicating entities in a decentralized network. The method begins with a recipient entity receiving data comprising a first timestamp and a first distance. The first timestamp being the time the first data was broadcast; the first distance being a distance from the sender's synchronization time. Next the recipient entity receives data comprising a second timestamp and a second distance. The second timestamp being the time the second data was broadcast; the second distance being a distance from the sender's synchronization time. Based on the first and second timestamps and distances, the recipient entity calculates a new synchronization time. Next, the recipient entity broadcasts to at least one entity in the decentralized network data comprising a third timestamp and a third distance. The third timestamp being the time the third data was broadcast; the third distance being a distance from the recipient entity's synchronization time.
