摘要： Methods and apparatuses for extracting information from a database based on tag data are provided. One method includes interrogating a plurality of RFID tags coupled with objects within in an area to obtain tag data. The contextual environment of the area is determined based on the tag data. A search of a database relating to an item in the area is conducted. Relevance rankings of search results are adjusted based upon the determined contextual environment. Search results can be displayed in order of relevance rankings.

摘要： The circuitry introduced in this invention selectively slows down the functioning of an electronic circuit maintaining a particular state for a prolonged period of time. This circuitry is used not only to achieve the desired effect in maintaining security from electronic thieves trying to circumvent codes but also in other applications such as enabling a circuit to continue to function in the event of a brief loss of power. For example, in an RFID system, if a reader is frequency hopping, a tag loses power for as long as about 400 milliseconds when the reader changes to other frequencies. In a preferred embodiment, the disclosed circuitry is used in conjunction with a destruct sequence.
摘要翻译：在本发明中引入的电路选择性地减慢保持特定状态长时间的电子电路的功能。该电路不仅用于在维护电子窃贼试图绕过代码的安全性方面实现期望的效果，而且在其他应用中，例如使电路在短暂的功率损失的情况下继续工作。例如，在RFID系统中，如果读取器跳频，当读取器改变到其他频率时，标签失去长达约400毫秒的功率。在优选实施例中，所公开的电路与破坏序列结合使用。

摘要： A system and method of inventorying multiple objects utilizing a multi-level or a chained radio frequency identification system. The system includes a master tag and a plurality of upper level tags and lower level tags associated with respective objects. The upper and lower level tags communicate with each other and the master tag so that reading of the master tag reveals the presence and absence of upper and lower level tags. In the chained RF system, the upper and lower level tags communicate locally with each other in a manner so that more remote tags that are out of range of some of the upper and lower level tags have their information relayed through adjacent tags to the master tag and thence to a controller.
摘要翻译：使用多级或链式射频识别系统对多个物体进行盘点的系统和方法。该系统包括主标签和与相应对象相关联的多个上级标签和下级标签。上层和下层标签相互通信和主标签，使得主标签的读取显示上下标签的存在和不存在。在链式RF系统中，上级和下级标签之间以本地方式进行通信，使得超出某些上级和低级标签范围的更远的标签将其信息通过相邻标签中继到主标签然后到控制器。

摘要： Embodiments of the present invention include systems with Readers and Tags in which a Reader queries the Tags with a parameter that includes a level of probability of reply according to which the Tags individually and randomly decide whether or not to reply. In one embodiment, the Tags can switch between two states: A and B. The query command also specifies a state (A or B) so that only the Tags in the specified state can reply. After successfully sending the Tag identification data from a Tag to the Reader, the Tag switches to the other state from the specified state. In one embodiment, the operations about the two states are symmetric. In one embodiment, the Tags can remember the parameters used in a query so that a short form of query command can be used to repeat the query with the same query parameters.
摘要翻译：本发明的实施例包括具有读取器和标签的系统，其中读者使用包括答复概率级别的参数来查询标签，根据该级别，标签单独并随机地决定是否回复。在一个实施例中，标签可以在两个状态之间切换：A和B.查询命令还指定状态（A或B），使得仅指定状态的标签可以回复。标签识别数据从标签成功发送到读卡器后，标签将从指定状态切换到其他状态。在一个实施例中，关于两个状态的操作是对称的。在一个实施例中，标签可以记住在查询中使用的参数，使得可以使用简短形式的查询命令来重复具有相同查询参数的查询。

摘要： Methods and apparatuses for configuring antennae of radio frequency identification reader systems. In one aspect of an embodiment, a radio frequency identification (RFID) reader system, includes: a receiver; a radio frequency (RF) source for signal transmission; and a switch matrix coupled with the receiver and the radio frequency sources to selectively couple the receiver and the radio frequency source to a plurality of non-collocated antennae. When in a first mode, the switch matrix connects the radio frequency source to a first one of the antennae for signal transmission and the receiver to a second one of the antennae for signal reception; and when in a second mode, the switch matrix connects the first one of the antennae for signal reception and, in one example, the second one or another one of the antennae to the RF source for signal transmission.

摘要： A method and apparatus for communicating between a host and a motor vehicle, the motor vehicle including an on board computer system having a bus for communicating with a plurality of motor vehicle systems. The apparatus includes an electronic tag having a transceiver for transmitting data to and receiving data from the host, a memory for storing bus requests and bus response data, a decoder for decoding requests from the host, a bus interface for reading data from and writing data to the bus, a controller and a filter. The bus interface extracts responses from the bus responsive to requests from the host. The responses may be stored in the memory. The controller is responsive to write requests from the host to transfer data to the bus interface and responsive to read requests from the host to transfer data stored in memory back to the host. The filter is operable to filter responses received from the bus and includes a filter database. The filter database includes one or more screening parameters for screening responses received from the bus.
