System and method for fall prevention and detection
First Claim
1. A method to determine a status of a person, comprising the steps of:
- receiving an indication from a first sensor, of a first orientation of a first body part of the person relative to a predetermined direction;
receiving an indication from a second sensor, of a second orientation of a second body part of the person relative to the predetermined direction, wherein the second body part is separately moveable from the first body part;
inferring, by use of a processor, an orientation of the person from the indication from the first sensor of the first orientation and the indication from the second sensor of the second orientation; and
determining, by use of a processor, the status of the person from an allowability of the inferred orientation of the person.

Abstract
System and method to determine a status of a person, the method including: receiving a sensor indication of a first orientation of a first body part of the person relative to a predetermined direction; receiving a sensor indication of a second orientation of a second body part of the person relative to the predetermined direction; receiving a sensor indication of a location of the person; inferring, by use of a processor, an orientation of the person from the sensor indication of the first orientation and the sensor indication of the second orientation; and determining, by use of a processor, the status of the person from an allowability of the inferred orientation of the person at the indicated location.

19. A system to determine a status of a person, comprising:
-
a first sensor coupled to a first body part of the person, the sensor configured to indicate an orientation of the first sensor relative to a predetermined direction; a second sensor coupled to a second body part of the person, the second sensor configured to indicate an orientation of the second sensor relative to a predetermined direction, wherein the second body part is separately moveable from the first body part; a central monitor, comprising; a processor; a memory coupled to the processor, the memory comprising storage of allowable orientations of the person; a first receiver configured to receive data from the first sensor; a second receiver configured to receive data from the second sensor; an inference module configured to infer an orientation of the person from the orientation of the first sensor and the orientation of the second sensor; and an interface to provide an alert, wherein the central interface monitor is configured to provide an alert if the allowable orientations of the person does not comprise the inferred orientation of the person. - View Dependent Claims (20, 21, 22, 23, 24)
