METHOD AND APPARATUS FOR ESTIMATING BLOOD PRESSURE
First Claim
1. A method of estimating blood pressure, the method comprising:
- sensing a value of a first sphygmus wave in a region of a user'"'"'s body while pressurizing the region with a first pressure;
sensing a value of a second sphygmus wave in the region while pressurizing the region with a second pressure; and
estimating blood pressure of the region based on sensed values of the first sphygmus wave and the second sphygmus wave, whereinthe first pressure and the second pressure are each one of a variable pressure and a constant pressure, anda height of the region, relative to the user'"'"'s body, is different for the sensing the value of the first sphygmus wave than for the sensing the value of the second sphygmus wave.

Abstract
A method for estimating blood pressure includes: sensing a value of a first sphygmus wave in a region of a user'"'"'s body while pressurizing the region with a first pressure; sensing a value of a second sphygmus wave in the region while pressurizing the region a second pressure; and estimating blood pressure of the region based on the sensed values of the first sphygmus wave and the second sphygmus wave. The first pressure and the second pressure are each either a variable pressure or a constant pressure. A height of the region, relative to the user'"'"'s body, is different for the sensing the value of the first sphygmus wave than for the sensing the value of the second sphygmus wave.
