OPTIMIZING RFID READER DUTY CYCLE OR POWER TO PRESERVE BATTERY LIFE |
摘要 |
The duty cycle of a portable battery-powered RFID tag reader is reduced during time periods when it is less likely to produce a "read" in order to preserve battery life. The reader operates with an aggressive duty cycle during periods of a high probability of a tag read and reduces duty cycle during periods of a low probability of a tag read. In this manner a user does not perceive the reader to be sluggish. An alternative embodiment reduces peak operating power during time periods when a tag is less likely to produce a "read" in order to preserve battery life. |
