Abstract
An exit prediction system for a support apparatus receives data inputs from one or more force sensors without zeroing the one or more force sensors. Changes in the data inputs are detected to determine whether the detected changes indicate a movement trend. An exit prediction is determined based at least partially on the movement trend, and without combining the data inputs from the one or more force sensors to determine the occupant's weight. A notification is generated based on the exit prediction.
Claims13
An exit prediction system comprising:
- a bed including:
- a frame;
- one or more force sensors positioned on the frame;
- and
- a computing device included on the bed, the computing device including:
- a processing unit;
- and
- a memory in communication with the processing unit;
- the memory storing machine-readable instructions that, when executed by the processing unit, cause the processing unit to:
- receive data inputs from the one or more force sensors, the data inputs being received without zeroing the one or more force sensors, wherein the data inputs are analog-to-digital (A/D) counts;
- detect changes in the data inputs from the one or more force sensors, wherein the detected changes in the data inputs are detected changes in the A/D counts received from each of the force sensors individually;
- store predefined changes in A/D counts associated with movement trends, wherein the movement trends are associated with movements performed by occupants in order to exit the bed;
- determine whether the detected changes indicate a movement trend by comparing the detected changes to the predefined changes to determine whether the detected changes are indicative of the movement trend;
- determine an exit prediction based at least partially on the movement trend, the exit prediction being determined without combining the data inputs from the one or more force sensors to determine a weight of an occupant of the bed;
- and
- generate a notification based on the exit prediction, wherein the notification is generated on the bed.
A method of predicting an occupant exit from a support apparatus, the method comprising:
- receiving data inputs detected from one or more force sensors positioned on a frame of the support apparatus, wherein the data inputs are analog-to-digital (A/D) counts representing voltage or current magnitudes of the one or more force sensors, and the data inputs are received without zeroing the one or more force sensors;
- detecting changes in the data inputs from the one or more force sensors without combining the data inputs to determine a weight of an occupant of the support apparatus, the detected changes in the data inputs are detected changes in the A/D counts received from each of the force sensors individually;
- storing predefined changes in A/D counts associated with movement trends, wherein the movement trends are associated with movements performed by occupants in order to exit the support apparatus;
- determining whether the detected changes indicate a movement trend by comparing the detected changes to the predefined changes to determine whether the detected changes are indicative of the movement trend;
- determining an exit prediction based at least partially on the movement trend, the exit prediction indicating a likelihood for the occupant exit from the support apparatus;
- and
- generating a notification based on the exit prediction, wherein the notification is generated on the support apparatus.
