Abstract
Systems and methods for detecting a presence of a person, robot or object in a given area using a hybrid Lighting and Inventory (“LI”) system. The methods comprise: maintaining a data store of identifiers for first tags that are readable by an internal circuit of at least one light provider; tracking (a) changes in which of said first tags are read by the at least one light provider's internal circuit during consecutive tag read processes and (b) changes in power levels of tag read signals received at the at least one light provider during the consecutive tag read processes; and using tracked information (a) and (b) to detect the presence of the person, robot or object in the given area.
