First Claim
Patent Images
1. A method of analyzing composition of a body, the method comprising:
- providing a first current signal having a first frequency to a first current path through the body and between a first upper extremity and a first lower extremity;
simultaneously with providing of the first current signal, providing a second current signal having a second frequency distinguishable from the first frequency to a second current path through the body and between a second upper extremity and a second lower extremity;
measuring voltage signals from voltage measuring positions of the four extremities while the first and second current signals are applied, each extremity comprising at least one of the voltage measuring positions;
processing the measured voltage signals to determine a first value representing impedance of a first body segment with respect to the first frequency and a second value representing impedance of a second body segment with respect to the second frequency,wherein the first body segment is one of upper extremities, wherein said processing comprises estimating a third value representing impedance of the other upper extremity with respect to the first frequency based on the first value.

Abstract
A method of analyzing a composition of a human body having a plurality of body segments is disclosed. The method can include applying a current signal to a body. The method can further include simultaneously measuring a plurality of voltage signals from a plurality of measuring positions of the body during a predetermined period, and processing at least two of the plurality of voltage signals to determine a composition parameter of a body segment so as to assess or analyze composition of the body.
