Abstract: A method and an apparatus for non-invasive blood-pressure measurement performing step-by-step inflating and deflating of the cuff pressure are disclosed. The step-by-step inflation-and-deflation process of the invention can determine the highest inflating pressure and provide enough data to obtain a curve fitting envelope. Therefore, the inflation pressure of the cuff to be pumped much higher than the normal systolic pressure of the conventional method can be prevented. A comfortable systolic and diastolic pressure determination method applying fuzzy control is achieved.

Abstract: A method and an apparatus for oscillometric blood-pressure measurement taking heart pulses for reference to determine the systolic and diastolic pressure are disclosed. The cuff is merely inflated to a cuff pressure above the mean arterial pressure of the artery. Therefore, the inflation pressure of the cuff to be pumped much higher than the normal systolic pressure of the conventional method can be prevented. A comfortable systolic and diastolic pressure determination method applying fuzzy control is achieved.

Abstract: A thermometer having a symmetrical probe with a sensor for sensing temperatures and a processor, a method for calculating temperature of an object by a second-order differential equation comprises the steps of obtaining temperatures from object, performing a first temperature calculation to obtain an initial prediction of temperature of object, adding a compensation coefficient, generating a compensated temperature based on a combination of initial prediction of temperature of object and compensated coefficient, and calculating a stabilized prediction of temperature of object based on compensated temperature before sensor has reached temperature of object. This thermometer can effectively decreasing error during heat transfer process.
