摘要： Described herein are methods, devices and systems for characterizing an attached antenna to an electronic device, such as a radio frequency identification ("RFID") reader. One exemplary embodiment is related to a method comprising outputting a low amplitude modulation ("AM") index radio frequency ("RF") waveform, the waveform simulating tag data timing and bandwidth, removing a direct current ("DC") component from the waveform to create a chopped portion of the waveform, applying at least one vector analyzer technique on the chopped portion of the waveform, characterizing at least one antenna impedance vector of the waveform.

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 by transferring a token, represented by a signal. Possession of the token enables the reader to access a RF communications medium. Readers can be arranged in a ring configuration, and interconnected via wired links. A secondary token may circulate in the ring in addition to the primary token, to ensure redundancy in the system. A reader waits for a predetermined time interval before accessing the RF communications medium.

摘要： Described are a method and a system for measuring radio frequency ("RF") power utilizing a radio frequency identification ("RFID") sensor tag embedded in an antenna. The method includes receiving at a communication device, a RF power level measurement from a sensor, adjusting an RF power level of the communication device based on the received power level measurement, wherein the sensor is external to the communication device. The system includes a sensor producing an RF power level measurement, and a communication device transmitting an RF signal and connected to the sensor, the communication device receiving the power level measurement from the sensor and adjusting a power level of the RF signal transmitted by the communication device based on the received RF power level measurement.

摘要： A thermal management system and method to control temperature in an RFID reader is described herein. In particular, by inserting variable periods of inactivity (or latency) at the beginning or at the end of each read cycle, proportional to an instantaneous temperature value of the RFID reader, over-heating and damage of RFID reader electronics is prevented. The RFID reader includes a thermal sensor and determines when the high power RF electronics is enabled. If the RFID reader is in an over-heated condition, it can be turned OFF and during this period any requests received on an interface to the RFID reader to perform a read of tag(s) are not processed.
摘要翻译：本文描述了用于控制RFID读取器中的温度的热管理系统和方法。特别地，通过在每个读取周期的开始或结束处插入可变时间段（或等待时间），与RFID读取器的瞬时温度值成比例，防止了RFID读取器电子器件的过热和损坏。 RFID读取器包括热传感器，并确定何时启用高功率RF电子设备。如果RFID读取器处于过热状态，则可以将其关闭，并且在此期间，不会处理在RFID读取器的接口上接收到的用于执行标签读取的任何请求。

摘要： The present invention is directed to a device and method for displaying content of a radio frequency identification (RFID) tag. The device includes an RFID reader, an interface module, and a laser projection display (LPD). The RFID reader sends instructions to and receives data from an RFID tag. The interface module converts the received data into a format for display. The LPD displays information relating to the data received from the RFID tag. The LPD may display the information directly on an item to which the RFID tag is affixed, or it may display the information on a screen diffuser. The information that is displayed may be numerical data stored in the RFID tag, an iconographic representation of an item to which the RFID tag is affixed, a full resolution image of the item to which the RFID tag is affixed, or the like.
