Claim 14:
15. An electronic reference device operable in a system comprising an associated electronic device and a plurality of other electronic reference devices, the electronic reference device comprising:
memory circuitry;
interface circuitry; and
processor circuitry;
wherein the processor circuitry is configured to:
receive a first signal from the associated electronic device, and
upon expiry of at least one predetermined anchor delay time period known to both the electronic reference device and the associated electronic device, transmit, to the associated electronic device, a second signal having a pulse width below a threshold and information that identifies the electronic reference device from among a plurality of other electronic reference devices in operative communication with the associated electronic device,
wherein the at least one predetermined anchor delay time period known to both the electronic reference device and the associated electronic device is different than each of a plurality of other predetermined anchor delay time periods unique to each of the plurality of other electronic reference devices thereby allowing the second signal to be transmitted to the associated electronic device spaced apart in time by the anchor delay time period relative to transmissions from the plurality of other electronic reference devices to the associated electronic device.
