METHODS AND SYSTEMS FOR DETECTING POTENTIAL INJURY CONDITIONS
Last updated:
Abstract:
A system includes a sensor attached to an individual and detects an individual's improper body movements that increase injury risk. The system includes a safety tag with an accelerometer that measures proper acceleration. Proper acceleration along multiple directions are projected onto multiple 2-D planes, generating acceleration vectors. Phasor angles of the acceleration vectors are calculated, and if the spread in phasor angles for any one 2-D plane within a moving time window exceeds a threshold, the system determines that the individual has made an improper body movement.
