摘要： A system and methods for measuring the temperature of an RFID reader module and inserting a delay in the RFID reader's duty cycle to prevent the RFID reader from initiating a thermal shutdown. The system and methods are self-adaptable, therefore incurring the benefit regardless of the design of the RFID reader host and its associated heat sink. The system and methods also provide for archiving the collected data and analyzing the data providing the ability to improve the design of the RFID reader host.

摘要： A system, apparatus, and techniques for interrogating a Radio Frequency Identification (RFID) tag are disclosed. The system includes an RFID reader that includes a pivotable polarized antenna for reading a reader/tag link. The antenna moves at a specific frequency over a specific distance resulting in reader/tag links being moved out of a null region of the reader. Advantageously, by pivoting the antenna, the antenna apparatus minimizes signal fading and improves signal quality from tags.
