Abstract

An RFID tag interrogator is described. The interrogator comprises a time-out circuit and an actuatable RF signal generator for transmitting an electromagnetic signal. Upon first actuation, the RF signal generator transmits a first electromagnetic signal having a first limited total continuous transmit time that is no longer than a predetermined transmit-time. That transmission is followed by an interim period of a defined length where the time-out circuit renders the interrogator incapable of transmitting the electromagnetic signal. The interim period is followed by the RF signal generator transmitting a second electromagnetic signal having a second limited total continuous transmit time that is no longer than the predetermined transmit time. The time-out circuit prevents the first, second and subsequent transmissions of the electromagnetic signal that are each no longer than the predetermined transmit time after a prior electromagnetic signal has been transmitted until the interim period has expired.
