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.
Claims16
A system for increasing accuracy of hygiene compliance in medical facilities, the system comprising:
- a remote computer server;
- a relay device situated within a medical facility and configured to relay hygiene compliance data to a hygiene compliance datastore, wherein the remote computer server is communicatively coupled to the hygiene compliance datastore and configured to receive the hygiene compliance data from the hygiene compliance 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 a first subset of the hygiene compliance 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 the first subset of the hygiene compliance 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 hygiene compliance data that is stored in the hygiene compliance datastore.
A computer implemented method for increasing accuracy of hygiene compliance in medical facilities, the method comprising:
- determining received signal strength between a tag and one or more location beacons;
- transmitting the received signal strength to a hygiene compliance datastore;
- determining one or more of tag accelerometer data, orientation data, heading data, or tag movement data;
- transmitting the one or more of the tag accelerometer data, the orientation data, the heading data, or the tag movement data to the hygiene compliance datastore;
- processing, by a computer, data stored in the hygiene compliance datastore;
- determining hygiene compliance based at least on the processed data;
- determining positions of a plurality of location beacons in a coordinate system;
- transmitting the positions of the plurality of location beacons to the hygiene compliance datastore;
- determining possible and impossible movement paths of the tag;
- transmitting the possible and impossible movement paths of the tag to the hygiene compliance datastore;
- determining one or more of usage of logs, timestamps associated with the tag, or timestamps associated with a use of a hygiene dispenser;
- transmitting the one or more of the usage of logs, the timestamps associated with the tag, or the timestamps associated with the use of a hygiene dispenser to the hygiene compliance datastore;
- processing, by the computer, the data stored in the hygiene compliance datastore;
- and
- determining the hygiene compliance based at least on the processed data.
