System and method for monitoring individuals and objects associated with wireless identification tags
First Claim
1. A system for monitoring individuals and objects in an area, the system comprising:
- at least one wireless identification tag, the at least one wireless identification tag including memory, the memory having information stored therein, the information being associated with at least one of a person and object associated with the at least one wireless identification tag; and
an interrogator, the interrogator wirelessly transmitting an interrogation signal, the interrogation signal including a sequence of interrogation codes, at least one of the interrogation codes being associated with the at least one wireless identification tag, the at least one wireless identification tag wirelessly transmitting an acknowledgment signal in response to receiving the at least one interrogation code associated with the at least one wireless identification tag, the acknowledgment signal being associated with the at least one wireless identification tag, the acknowledgment signal including at least a portion of the information, the interrogator receiving the acknowledgment signal, thereby monitoring at least one of the person and object.

Abstract
A monitoring system includes a wireless identification tag and interrogator. The tag includes memory that stores information associated with a person or object associated with the wireless identification tag. The interrogator wirelessly transmits an interrogation signal, which includes a sequence of interrogation codes, to the wireless identification tag. If one of the interrogation codes is associated with the wireless identification tag, the tag wirelessly transmits an acknowledgment signal associated with the tag. The interrogator receives the acknowledgment signal, which indicates that the wireless identification tag has been monitored within an area. A method of monitoring a person or object within a defined area includes the steps of storing information in a wireless identification tag; transmitting an interrogation signal; receiving the interrogation signal by the tag; determining whether an interrogation code in the received interrogation signal is associated with the tag and, if so, transmitting an acknowledgment signal.
