Posture and body movement measuring system
First Claim
1. A device for attaching to a living subject having a joint, comprising a first sensor, a second sensor, a processor, and a non-volatile storage device, said first sensor for attaching to a first body segment above the joint, said second sensor for attaching to a second body segment below the joint, wherein said first sensor and said second sensor each comprise a solid state inclination measuring device for determining inclination with respect to the gravity vector, wherein said inclinations with respect to the gravity vector determined from said first sensor and from said second sensor are processed in said processor and stored in said non-volatile storage for distinguishing lying, sitting, and standing positions, wherein said processor and said non-volatile storage device are part of the device for attaching to the living subject.

Abstract
A sensing device is attached to a living subject that includes a first sensors for distinguishing lying, sitting, and standing positions. In another embodiment, sensor data is stored in a storage device as a function of time. Multiple points or multiple intervals of the time dependent data are used to direct a feedback mechanism to provide information or instruction in response to the time dependent output indicating too little activity, too much time with a joint not being moved beyond a specified range of motion, too many motions beyond a specified range of motion, or repetitive activity that can cause repetitive stress injury.
