Patent ID: 7210240

Claim:
A device for communicating to a user, comprising a solid state sensor, a processor, a non-volatile storage device, and a feedback mechanism, wherein said solid state sensor, said processor, and said non-volatile storage device are for mounting on the user, wherein data from said sensor is processed in said processor to provide an output, wherein said output is stored in said non-volatile storage device as a function of time, and wherein multiple points of said time dependent output stored in said non-volatile storage device are processed in said processor, wherein said feedback mechanism includes a device for communicating with the user, wherein said processor is programmed to direct said feedback mechanism to commnunicate to the user at least one from the group including information and instruction in response to said multiple points of time dependent output indicating at least one from the group including inactivity, activity of a joint during an interval of time that is less than a preset level of activity, a range of motion of a joint during an interval of time that is less than a preset range of motion, and vibration during an interval of time that is greater than a preset amount of vibration, wherein said sensor includes an inclination measuring device.
