Patent ID: 8514087

Claim:
A sensor system, comprising: a first sensor, to be worn by a subject, outputting first sensor data indicative of measured trunk movement of the subject; a second sensor, to be worn by the subject in conjunction with the first sensor, outputting second sensor data indicative of a measured thigh movement of the subject; a computing unit, in communication with the first sensor and the second sensor, the computing unit storing program instructions for execution by the computing unit to: receive the first sensor data and the second sensor data; calculate a risk level associated with the measured trunk movement of the subject and the measured thigh movement of the subject; output a feedback signal indicative of the risk level of a movement of the subjects and classify a movement of the subject as corresponding to one or more predetermined lifting strategies based on (i) a trunk angle determined based on the measured trunk movement and (ii) a thigh angle determined based on the measured thigh movement.
