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.
Claims82
A device for attaching to a living subject, comprising a first sensor, a second sensor, a processor, and a storage device, said a first sensor for attaching to a first body segment above a hip joint, said second sensor for attaching to a second body segment below the hip joint, wherein said first sensor and said second sensor each comprise an inclination measuring device, wherein data from said first sensor and from said second sensor is processed in said processor and stored in said storage device for distinguishing lying, sitting, and standing positions.
A device as recited in claim 16, further comprising a housing, wherein said first sensor, said storage device, said processor, and said feedback mechanism are all within said housing.
A device comprising a sensor, a processor, a storage device, and a feedback mechanism wherein data from said sensor is processed in said processor to provide an output, wherein said output is stored in said storage device as a function of time, and wherein multiple points of said time dependent output stored in said storage device are processed in said processor, wherein said processor directs said feedback mechanism to provide information or instruction in response to said multiple points of time dependent output indicating too little activity or too small a range of motion of a joint during an interval of time, or repetitive activity that can cause repetitive stress injury or too many motions beyond a specified range of motion during an interval of time or too much vibration for too long a time.
