Systems for and methods of assigning priority to reader antennae
First Claim
1. A method of operating a plurality of reader antennae, the method comprising the steps of:
- determining a priority order of the plurality of reader antennae; and
setting a polling sequence for reading the plurality of reader antennae according to the priority order determined in said determining step;
wherein said determining step further comprising the steps of;
assigning a preference level to each of the plurality of reader antennae; and
deriving a priority order based on the preference levels assigned to each of the plurality of reader antennae;
wherein said assigning step comprises assigning preference levels based on products detected by each of the plurality of reader antennae;
wherein said assigning step comprises the steps of;
calculating for each of the plurality of reader antennae a probability that a detected product will be moved from a predetermined location; and
assigning a preference level to each of the plurality of reader antennae based on the probability calculated.

Abstract
Method, systems, and articles of manufacture for assigning priority to antenna are disclosed. In accordance with a preferred embodiment of the invention, reader antenna (151, 152, 153) identify the location of an object by detecting a tag or other identifier associated with each object. Sensors (121, 122, 123) can be provided to provide additional information regarding the environment of the objects to their surroundings. A priority order is assigned to the reader antenna based on the location and other characteristics of the objects and/or their environment. A polling sequence for reading the reader antennae is determined according to the priority order.
