    摘要： The present invention is a blood pressure measuring device comprising an optical sensing unit adapted for detecting optical pulses at a plurality of locations on an external surface of a user. The device also comprises a processing unit coupled to the optical sensing unit for determining an optimal location from the plurality of locations based on the detected optical pulses and a pressure sensing unit adapted for detecting a pressure pulse of the user at a location of measurement. The present invention also discloses a method of measuring a blood pressure of a user using a blood pressure measurement device. The advantage of the present invention is that by using an optical sensing unit to locate the artery of the user, or to compensate the misalignment from the artery, the blood pressure is more accurately determined. With the calibration method, the deficient cuff calibration can be waived in certain circumstances.

    摘要： The present invention discloses a device for measuring physiological data of a subject. It comprises a light modulation unit, an optical detection unit and a signal processing unit. The present invention can operate in an active mode or a passive mode to measure a subject's heart rate, respiratory information, haemoglobin level, cardiac output or oxygen saturation of the blood, etc. Fourier Transform based lock-in technique is used to detect the physiological signals reliably even when the signal is weak. In addition, ambient light can be used as the light source to complete the measurement.
