First Claim
Patent Images
1. A method, comprising:
- emitting a signal at an initial power to activate electronically responsive tags;
receiving a response from one of the tags to the emitted signal;
determining an indicator of a signal strength received at the responding tag; and
adjusting downward a power of the emitted signal based on the determined indicator of the signal strength.

Abstract
Provided are a method, system, and article of manufacture for adjusting signal strength used to detect tags. A signal is emitted at an initial power to activate electronically responsive tags. A response is received from one of the tags to the emitted signal. A determination is made of an indicator of a signal strength received at the responding tag. A power of the emitted signal is adjusted downward based on the determined indicator of the signal strength.
