METHODS AND DEVICES FOR IDENTIFYING SELECTED OBJECTS
First Claim
1. A method of choosing an object from a plurality of objects using a wireless device, wherein each of the plurality of objects includes an RF interface configured to communicate using backscatter communication, the method comprising:
- receiving a backscatter communication signal from each of the plurality of objects;
determining at least one analog parameter of each backscatter communication signal;
using the wireless device, selecting one object of the plurality of objects based at least in part on the at least one analog parameter of each backscatter communication signal.

Abstract
A method of choosing an object from multiple objects using a wireless device includes receiving a backscatter communication signal from each of the objects, determining one or more analog parameter of each backscatter communication signal, and, using the wireless device, selecting one object based at least in part on the analog parameter of each backscatter communication signal. Each of the objects includes an RF interface configured to communicate using backscatter communication.
