    摘要: RFID readers, reader systems, and methods are provided for processing RFID tags through interruptions for antenna change or other reasons. If the reason for the interruption is an antenna change, the reader restarts processing the tags initializing any operational parameters. If the reason is other than an antenna change, the reader determines whether the operation is to be continued or to be restarted upon power up and proceeds accordingly.

    摘要: RFID readers, reader systems, and methods are provided that utilize smart antenna switching. A first signal is transmitted from a first antenna estimating presence of tags within the antennas field of view. If fewer than a predefined number of tags are estimated, the system switches to a second antenna. Otherwise, the tags found in the field of view of the first antenna are inventoried before switching to the second antenna.

    摘要: RFID reader systems, software and methods precompute one or more reader commands, before a tag actually responds to an earlier transmitted command. This way a system can result at a high data rate, while meeting specification requirements of responding within a preset time.

    摘要翻译: RFID标签系统,软件和方法在一个标签实际响应早期传输的命令之前预先计算一个或多个读取器命令。 这样一来,系统就可以达到高的数据速率,同时满足在预设时间内响应的规范要求。

    摘要: Radio Frequency IDentification (RFID) reader system, software, and methods are provided, such that an operational processing block for the RFID reader to communicate with an RFID tag uses a RF spectrum portion subdivided into a set of channels. The communication takes place in the presence of a foreign device that uses a subset of first channels of the RF spectrum and does not use a subset of second channels of the spectrum. The methods cause a radiating power directed towards the tag to be reduced and a radiating dwell time to be changed. This is to assure that co-existing systems can operate without compromising their functionality and operational quality. In some embodiments, the radiating power is reduced to zero.

    摘要: RFID tags and chips for RFID tags are capable of complying with only a limited number of remaining commands, and methods. In a number of embodiments, a counter is adjusted in association with receiving a command and complying with it. The tag complies until the counter reaches a limit, and then it can stop complying. Non-compliance can be by the tag becoming quiet, or performing other activities, or performing nothing at all, or performing only selected activities, and so on. In some embodiments non-compliance is permanent, while in others it is temporary and/or restorable.
