First Claim
1. A system for measuring and analyzing body mechanics of a subject, said system comprising:
- a. a plurality of ultrasonic receivers disposed on the body of the subject;
b. at least three ultrasonic transmitters disposed non-collinearly and in fixed and known positions adjacent to the subject;
c. a processor coupled to said ultrasonic receivers and said ultrasonic transmitters, said processor including;
i. a controller which controls the timing of signals from said ultrasonic transmitters so that a signal from each of said ultrasonic transmitters contains an encoded signature which unambiguously identifies said signal as coming from that particular one of said ultrasonic transmitters;
ii. a detector which detects ultrasonic signal transmissions as said ultrasonic signal transmissions arrive at said ultrasonic receivers;
iii. a signature determinator which recognizes said encoded signature and determines from which particular one of said ultrasonic transmitter said detected signal originated;
iv. a local timer which measures the time difference between time of emission of each of said signals from said ultrasonic transmitters and detection of each of said signals at said ultrasonic receivers; and
v. a calculator which computes geometric distances between each of said ultrasonic transmitters and each of said ultrasonic receivers and which also calculates a three-dimensional position of each of said ultrasonic receivers by using said geometric distances and known position of each of said ultrasonic transmitters; and
d. a display coupled to said processor for use in reviewing and analyzing body mechanics of the subject.

Abstract
A system for measuring and analyzing body mechanics of a subject includes receivers, transmitters, a display and a processor. The processor which includes a controller which controls the timing of signals from the transmitters so that a signal from each of the transmitters contains an encoded signature which unambiguously identifies the signal as coming from that particular the transmitter. The processor also include a detector which detects signal transmissions as the signal transmissions arrive at the receivers, a signature determinator which recognizes the signature and determines from which particular transmitter the detected signal originated, a local timer which measures a temporal delay between times of emission of the signals from the transmitters and their detection at the receivers. A calculator computes geometric distances between each of the transmitters and each of the receivers and which also calculates a three-dimensional position of each of the receivers by using the geometric distances and known position of the transmitters.
