1. A motion monitoring system comprising:
- a plurality of self-powered active Radio Frequency Identification (RFID) transmitters each intermittently transmitting RF pulses at a rate proportional to motion of a user wearing said RFID transmitters, wherein each RFID transmitter transmits an RF pulse upon reaching a predefined threshold, said RF pulse comprises identification information and motion information pertaining to a pattern of activity being performed by said user, said pattern of activity being quantitatively represented in any of a graphical and mathematical manner, said user comprising a human being, and said pattern of activity comprises predefined movements performed by said user, and wherein said each RFID transmitter comprises a triaxial piezoelectric accelerometer that senses said motion of said user; and
a receiver that receives and analyzes said RF pulses produced by each of said RFID transmitters to identify said pattern of activity and produce meaningful data characterizing said pattern of activity, wherein said receiver compares a variance in said pattern of activity with previously saved data of a previous pattern of activity of said user and with data related to a standard, predefined description of said pattern of activity to determine differences over time of the patterns of activity of said user, wherein said receiver calibrates and re-calibrates said RF pulses, wherein said receiver is calibrated and re-calibrated based on said pattern of activity being performed by said user, and wherein the re-calibration of said receiver occurs based on a specific pattern of activity of a particular user compared with said previously saved data and said predefined data.

Abstract
A system, apparatus, and method for motion monitoring. In an embodiment, a plurality of self-powered active Radio Frequency Identification (RFID) transmitters are each configured to intermittently transmit radio frequency pulse at a rate proportional to motion, containing identification information. The pulse produced by each of the RFID transmitters are received and analyzed at a receiver. The analysis results in the identification of pattern of activity, which is used to produce meaningful data regarding the motion of a user. The RFID transmitters may be provided on a wearable tag.

14. A method for monitoring physical motion of a human user, said method comprising:
-
attaching at least one Radio Frequency Identification (RFID) transmitter worn on a body part of said human user; converting physical motion of said human user into electric charge at the RFID transmitter; charging a charge storage element from said electric charge; discharging said charge storage element based on a predefined threshold; activating an RFID device using said electric charge to produce an RF pulse comprising identification information and motion information, wherein transmission of said identification information and motion information is based on said predefined threshold; transmitting said RF pulse from said RFID transmitter to a receiver to compare and analyze a pattern of said physical motion of said human user to a plurality of predefined patterns of activity; and comparing a variance in a pattern of activity of said user with previously saved data of a previous pattern of activity of said user and with data related to a standard, predefined description of said pattern of activity to determine differences over time of the patterns of activity of said user, wherein said receiver calibrates and re-calibrates said RF pulse, wherein said receiver is calibrated and re-calibrated based on said pattern of activity being performed by said user, and wherein the re-calibration of said receiver occurs based on a specific pattern of activity of a particular user compared with said previously saved data and said predefined data. - View Dependent Claims (15, 16, 17, 18, 19, 20)
