METHOD, SYSTEM AND APPARATUS FOR FALL DETECTION
First Claim
1. A method for detecting a fall, comprising:
- receiving data from at least one sensor associated with a person;
analyzing the received data to detect changes therein;
detecting the person is falling or that a fall is imminent based on the analysis of the received data;
issuing a warning;
administering to the person, in response to the detection, a neurological test requiring the person to manually or orally input a level of responsiveness or awareness; and
logging to a memory at least of one a date and time of the fall or one or more results of a test administered to the person.

Abstract
Methods, systems, and apparatuses are provided for detecting fall events of a person. Fall events are falls that are likely to occur, are occurring, or have occurred. Fall detectors and fall detector systems detect fall events of the person. Data relating to the person are received from sensors and analyzed to perform fall detection. Data relating to the person includes accelerations and forces experience by the person, changes in body position of the person, movements of the person, and body signals and sounds of the person. Neurological tests are administered to determine levels of responsiveness and awareness of the person in response to detections. Warnings are issued, and safety measures are deployed, in response to detections. Data relating to fall events are recorded and logged. Fall event histories based upon the logged data and fall detection algorithm performance are used to improve future fall detection and prediction.

16. A method for detecting whether a person has fallen, comprising:
-
receiving a measure of force from a sensor associated with the person; analyzing the measure of force with respect to time; detecting the person has fallen based on the analysis of the measure of force with respect to time; administering to the person, in response to the detection, a neurological test requiring the person to manually or orally input a level of responsiveness; logging to a memory at least one of, a date and time of the fall, a force of impact or results of the neurological test; and issuing a warning in response to the detection that the person has fallen. - View Dependent Claims (17, 18, 19)

20. A fall detection system, comprising:
-
at least one sensor associated with a user; a fall detection unit coupled to the at least one sensor, and configured to filter and analyze a measure of force determined by the at least one sensor and determine at least one of the user falling, the user has fallen, or a fall of the user is imminent; a neurological unit coupled to the fall detection unit and configured to administer a neurological test to the user in response to the at least one of the user falling, the user having fallen, or a fall of the user being imminent; a user-input unit coupled to the neurological unit and configured to receive a neurological test input from the user; and a communication unit coupled to the fall detection unit and to the neurological unit, and configured to communicate with at least one of a care-giver station, an emergency medical technology station, or a remote entity. - View Dependent Claims (21, 22, 23)

24. A fall detection system, comprising:
-
at least one of a tri-axial accelerometer, a clinometer, a force transducer, or a gyroscope attached to a user; a fall detection unit coupled to the at least one of the tri-axial accelerometer, the clinometer, the force transducer, or the gyroscope, and configured to filter and analyze motion data or force data received from the at least one of the tri-axial accelerometer, the clinometer, the force transducer, or the gyroscope and determine if the user is falling or that a fall is imminent; a neurological unit coupled to the fall detection unit and configured to administer a responsiveness test to the user; and a user-input unit coupled to the neurological unit and configured a receive a responsiveness test input from the user. - View Dependent Claims (25, 26)
