1. 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 andclassify 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.

Abstract
Systems and methods are discussed for providing a sensor enhanced employee safety evaluation system. Systems that monitor and assess employee lifting behavior are employed at the workplace of an insured entity. Data from the lift monitoring systems are processed to obtain a safety evaluation. Based on the safety evaluation, the insurance provider can adjust the terms of the insurance policy to accurately reflect the risks associated with the insured entity. Feedback based on the safety evaluation is also provided to the insured entity and the employees of the insured entity to promote improvements in safe behavior.

15. A sensor system, comprising:
-
a first sensor, to be worn by a subject, outputting first sensor data indicative of a 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 a measured thigh movement of the subject; determine a thigh angle based on the measured thigh movement; and output a feedback signal indicative of the risk level of a movement of the subject; wherein the computing unit further stores program instructions for execution by the computing unit to convert the determined thigh angle to a determined knee flexion angle.

16. A sensor system, comprising:
-
a first sensor, to be worn by a subject, outputting first sensor data indicative of a 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; and output a feedback signal indicative of the risk level of a movement of the subject; wherein the feedback signal indicative of the risk level is determined based in part on a lifting strategy employed by the subject. - View Dependent Claims (17, 18, 19, 20)
