摘要

Systems and methods for operating a Radio Frequency Identification (“RFID”) tag. The methods comprise: monitoring a level of Radio Frequency (“RF”) energy being received by the RFID tag; performing operations by a circuit of the RFID tag to compare the level of RF energy in a given frequency band to a first threshold value; and transitioning an operational mode of the RFID tag from a first operational mode in which a receiver is disabled to a second operational mode in which the receiver is enabled, when the level of RF energy exceeds the first threshold value. The RFID tag is able to communicate with a remote tag reader when the RFID tag is in the second operational mode and not when the RFID tag is in the first operational mode.

說明書

Upon completing 1224, method 1200 continues with 1226 of FIG. 12B. As shown in FIG. 12B, 1226 involves performing operations by a motion sensor (e.g., motion sensor 250 of FIG. 2) to detect motion of the RFID tag (e.g., RFID tag 1121, . . . , 112N, 1181, . . . , or 118X of FIG. 1). Next in 1228, the motion sensor performs operations to notify a controller (e.g., controller 210 of FIG. 2) of the RFID tag that motion has been detected. The motion sensor also provides motion sensor data to the controller. In 1230, the motion sensor data is analyzed to determine if the RFID tag is traveling through a facility. This analysis can be performed by the RFID tag's controller and/or a remote device (e.g., a tag reader or server). The analysis can involve detecting pre-defined patterns of movement specified in the motion sensor data (e.g., a walking pattern, a running pattern, or a vehicle traveling pattern). If a determination is made that the RFID tag is not traveling through a facility (e.g., RSF 128 of FIG. 1) [1232:NO], then 1234 is performed where method 1200 ends or other processing is performed (e.g., return to 1226).
