Abstract
A wireless time-of-flight distance measurement device and/or a motion detector is used at each of a plurality of stations in a wireless network in an enclosed facility to accurately locate a badge-wearing person near the station. The location, badge number and time of detection are transmitted through the network and stored in a computer memory. In a health care facility, hand-washing detectors are located at some of the stations and caused to energize a hand-wash status indicator light on the badge when the wearer has washed his or her hands. The light remains 'on' for only a certain length of time, but will be extinguished sooner by a monitor device near each patient when the health care worker leaves the vicinity of the patient. These events also are transmitted and stored so that a timed record of each worker's hand-washing and visits to patients is created.
