Systems for automatic assessment of fall risk
First Claim
Patent Images
1. A method of assessing the risk of a human being falling, comprising:
- providing a central sever system;
providing a plurality of sensors communicatively coupled to said central server system, none of said sensors being in physical contact with said human being at least one sensor in said plurality of sensors detecting that said human being attempting to exit a bed in which said human being is resting;
receiving at said central server system from said plurality of sensors data about said detected attempt of said human being to exit said bed;
said central server system extracting from said received data about said human being a plurality of data features including an indication of the human being'"'"'s bed exit procedure and the human being'"'"'s sit-to-stand time during said bed exit procedure;
said central server system determining a fall risk for said human being based at least in part on said extracted data features.

Abstract
Systems and methods for the automatic assessment of a person'"'"'s fall risk. The systems and methods utilize an objective standard and evaluation of a person'"'"'s gait and stance, among other factors, to determine such person'"'"'s current instantaneous likelihood of a fall, as well as such person'"'"'s future fall risk. The systems and methods utilize machine observations and calculations to reduce or eliminate bias and the use of subjective assessment criteria.

11. A system for assessing the risk of a human being falling, comprising:
-
a plurality of sensors, none of said sensors being in physical contact with said human being; a central sever system communicatively coupled to said plurality of sensors, said central server system comprising a microprocessor and a non-transitory computer-readable medium having computer-executable program instructions thereon which, when executed by said microprocessor, cause said central server to perform the steps of; receiving from said plurality of sensors data about said human being gathered by said plurality of sensors at least one sensor in said plurality of sensors detecting that said human being attempting to exit a bed in which said human being is resting and said data including data about said detected attempt of said human being to exit said bed; extracting from said received data about said human being a plurality of data features including an indication of the human being'"'"'s bed exit procedure and the human being'"'"'s sit-to-stand time during said bed exit procedure; determining a fall risk for said human being based at least in part on said extracted data features. - View Dependent Claims (12, 13, 14, 15, 16)
