Abstract
Embodiments of the present inventive concept leverage RSS patterns, accelerometer patterns, hygiene event information, and hub locations to increase accuracy of room-level positioning of objects and people, and to ensure a high accuracy detection of zone entry and/or exit times in an indoor environment, all of which facilitate an accurate hand hygiene compliance monitoring system in hospitals and other medical facilities, as well as a variety of other applications.
Claims17
A system for increasing accuracy of location tracking in medical facilities, the system comprising:
- a remote computer server;
- a relay device situated within a medical facility and configured to relay location data to a datastore, wherein the remote computer server is communicatively coupled to the datastore and configured to receive the location data from the datastore;
- one or more location beacons situated in a corresponding one or more known locations within a plurality of zones of the medical facility, wherein the one or more location beacons include a transceiver, wherein the one or more location beacons are communicatively coupled to the relay device, and configured to transmit the location data to the relay device;
- a plurality of tags having an initial unknown location, each of the tags including one or more of a transceiver or a transmitter, each of the tags being attached to one or more of a non-stationary object or a non-stationary person, wherein the one or more location beacons are configured to detect a signal strength between the plurality of tags and the one or more location beacons, and wherein a first subset of the location data includes the signal strength between the plurality of tags and the one or more location beacons;
- and
- wherein the remote computer server is configured to generate zone entry and exit times of the tags transiting the plurality of zones based at least on the first subset of the location data that is stored in the datastore.
A computer implemented method for increasing accuracy of location tracking in medical facilities, the method comprising:
- determining, by one or more location beacons, received signal strength between a tag and the one or more location beacons, wherein the tag is associated with an object;
- transmitting and storing the received signal strength to a datastore;
- determining one or more of tag accelerometer data, orientation data, heading data, or tag movement data;
- transmitting and storing the one or more of the tag accelerometer data, the orientation data, the heading data, or the tag movement data to the datastore;
- determining positions of a plurality of location beacons in a coordinate system;
- transmitting and storing the positions of the plurality of location beacons to the datastore;
- processing, by the computer, the data stored in the datastore including the positions of the plurality of location beacons;
- and
- determining a location of the object based at least on the processed data.
