Method of and reader for automatic synchronization of reader wakeup signals to radio tags
First Claim
1. A method for synchronizing wakeup signals transmitted by a plurality of readers to at least one radio tag, the method comprising:
- monitoring, by a first reader, for a first wakeup signal transmitted by a second reader; and
if the first wakeup signal is detected by the first reader, transmitting, by the first reader, a second wakeup signal having a duration ending at substantially the same time as the first wakeup signal.

Abstract
A method for synchronizing wakeup signals transmitted by a plurality of readers to at least one radio tag includes monitoring, by a first reader, for a first wakeup signal transmitted by a second reader. If the first wakeup signal is detected by the first reader, the first reader transmits a second wakeup signal having a duration ending at substantially the same time as the first wakeup signal. If the first wakeup signal is not detected by the first reader, the first reader transmits a third wakeup signal having a default duration. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

12. A first reader for transmitting at least one wakeup signal to at least one radio tag, the first reader comprising:
-
at least one computer readable medium; and
processor instructions contained on the at least one computer readable medium, the processor instructions configured to be readable from the at least one computer readable medium by at least one processor and thereby cause the at least one processor to operate as to;
monitor for a first wakeup signal transmitted by a second reader; and
if the first wakeup signal is detected, transmit a second wakeup signal having a duration ending at substantially the same time as the first wakeup signal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
