    • RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag acts as a passive RFID tag, and the information it holds can be read with a proximity reader. This operation is performed when the RFID tag is attached to the object to be monitored. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag. The RFID tag then acts as an active RFID tag and starts to emit messages which can be received by a RFID reader.
    • RFID标签和涉及多个RFID标签的系统和方法。 每个RFID标签连接到其上监视预定流体的存在的对象。 在第一状态(不存在被监视的流体)的情况下,标签用作无源RFID标签,并且可以用邻近读取器读取其保存的信息。 当RFID标签附着到被监视对象时,执行该操作。 在第二状态下,每当被监视的流体出现在被标记的物体上时,流体活化的电池产生用于为RFID标签供电的电力。 RFID标签然后用作有源RFID标签,并开始发射可由RFID读取器接收的消息。

    • The present invention describes a RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object (or to a structure or a person) on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag is acting as a passive RFID tag, and the information it holds, (at least its identifier—ID), can be read with a proximity reader (a hand held or stationary/fixed reader). This operation is performed when the RFID tag is attached to the object (or person) to be monitored. At this stage a table associating tag ID, object name (or person name) and location (or any other information), may be built, and may be recorded so that information it contains is accessible by a control center. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag. The RFID tag then acts as an active RFID tag and starts to emit messages (an alert for instance) which can be received by a distant RFID reader. Alert messages include at least the tag ID but may comprise additional information like a name or a location.
    • 本发明描述了RFID标签以及涉及多个RFID标签的系统和方法。 每个RFID标签被附接到在其上监视预定流体的存在的对象(或结构或人物)上。 在第一状态(不存在被监视的流体)的情况下,标签作为无源RFID标签,并且其保存的信息(至少其标识符ID)可以用邻近读取器(手持或 固定/固定式阅读器)。 当RFID标签附着到要监视的对象(或人)时,执行该操作。 在这个阶段,可以建立一个关联标签ID,对象名称(或人名)和位置(或任何其他信息)的表格,并且可以被记录,使得其包含的信息可由控制中心访问。 在第二状态下,每当被监视的流体出现在被标记的物体上时,流体活化的电池产生用于为RFID标签供电的电力。 RFID标签然后用作有源RFID标签,并开始发出可由远程RFID读取器接收的消息(例如警报)。 警报消息至少包括标签ID,但是可以包括诸如名称或位置的附加信息。

    • The present invention relates to a system and method of tamper detection. A tamper detection system in accordance with an embodiment of the present invention includes: a passive electronic sensor including a circuit having first, second, and third nodes; a load connected between the first and second nodes of the circuit; a friable electrical connection element connected between the second and third nodes of the circuit; and a storage unit, connected to the second node of the circuit, for storing an identification code of the sensor; wherein in use a voltage is applied across the first and third nodes of the circuit, and when the friable electrical connection element is intact, the second node of the circuit is at a first voltage, and when the friable electrical connection element is broken, the second node of the circuit is at a second voltage.
    • 本发明涉及篡改检测的系统和方法。 根据本发明的实施例的篡改检测系统包括:无源电子传感器,包括具有第一,第二和第三节点的电路; 连接在电路的第一和第二节点之间的负载; 连接在电路的第二和第三节点之间的易碎电连接元件; 以及存储单元,连接到所述电路的第二节点,用于存储所述传感器的识别码; 其中在使用中电压施加在电路的第一和第三节点上,并且当脆性电连接元件完好时,电路的第二节点处于第一电压,并且当易碎电连接元件断开时, 电路的第二节点处于第二电压。
