Abstract:
1. A radio frequency identification (RFID) network for tracking a plurality of subjects in a closed environment with a plurality of entries, the network comprising a plurality of RFID readers distributed across the environment and a response computer system, wherein each respective RFID reader in a first subset of the plurality of RFID readers is positioned at an entry in the plurality of entries, and each respective RFID reader in the plurality of RFID readers includes a unique reader identifier and is in communication with the response computer system; and the response computer system comprises: a first event instruction set in the instruction event set data store corresponds to a first event and includes: (i) a first message that is to be sent to a first subset of subjects in the plurality of subjects without human intervention, responsive to the first event at a time when the first event occurs, wherein the first subset of subjects are selected from the plurality of subjects on the basis that they are (a) localized by the visual position map to a first portion of the closed environment or (b) associated with a first class label in the plurality of class labels corresponding to the first message, and (ii) a second message that is to be sent to a second subset of subjects in the plurality of subjects without human intervention, responsive to the first event at a time when the first event occurs, wherein the second subset of subjects are selected on the basis that they are (a) localized by the visual position map to a second portion of the closed environment, wherein the second portion of the closed environment is different than the first portion of the closed environment, or (b) associated with a second class label in the plurality of class labels corresponding to the second message; and the instructions further cause the response computer system to, in response to receiving an indication that the first event has occurred, execute the method of:
