36. A method of signal association, comprising the steps of:
-
receiving a first signal comprising unique data and a second signal comprising non-unique data at a location determining module; and determining if there is an association between the first signal and the second signal based on whether the first signal and the second signal were received within a selected time period of each other. - View Dependent Claims (37)

38. A location system, comprising:
-
an object identifier adapted to transmit a RF signal comprising unique data and a IR signal comprising non-unique data; and a location determining module adapted to receive the RF signal and the IR signal for determining a location of the object identifier from the RF signal and the IR signal, wherein the location detection module is adapted to associate the RF signal with the IR signal provided the signals are received within a selected time period of each other.
