Abstract: An identification tag has at least a controller, a receiver for receiving wireless signals from an exciter, and a transmitter for transmitting wireless signals to at least one location receiver (which may be a WLAN access point). The tag's controller can determine the presence of interference from sources unrelated to the location system, such as smartphones, tablets, computer monitors etc., and signal an alert accordingly.

Abstract: An article identification system relies upon correlating or “bonding” a detecting object with an identifying object on an auto-identification basis. Identification data is provided on an automated, high-reliability basis, without human control over the precise identification data that is transferred. On this basis a nursery infant-parent identifier system is provided whereby, when a detecting baby bracelet is brought into the presence of an identifying parent's tag, a reliable indication is provided as to whether the bracelet and tag have been previously bonded.
