  • Patent number: 10123694
    Abstract: An optical measurement device including a light emitting element, a light pattern generating element and a light source transmission element is provided. The light pattern generating element includes a disk body, at least one round hole penetrating the disk body, at least one round disk embedded in the round hole, and at least two first magnetic elements disposed on the round disk. One end of the light source transmission element has two second magnetic elements. Through the magnetic connection of the first magnetic elements and the second magnetic elements, a chink on the round disk can rotate with the light source transmission element when the light source transmission element rotates. An optical measurement system including the optical measurement device is also provided.

  • Patent number: 9445718
    Abstract: An optical system for measuring an observed object includes an illuminant component, an imaging component, and an optical component. The illuminant component generates a measuring light. The optical component including a mirror and a beam splitter is located between the illuminant component and the imaging component. The mirror is located between the illuminant component and the observed object, the beam splitter is located between the mirror, the observed object, and the imaging component. The measuring light is projected to the observed object via the mirror and beam splitter, and an imaging light that has been generated from the illuminant component and reflected by the observed object is projected to the imaging component via the beam splitter, the imaging light and the measuring light intersect at the beam splitter. The present invention also provides a measurement method.

  • Patent number: 9258300
    Abstract: The present invention discloses at least two electrodes disposed at the body of the ECG measuring device of the present invention. When a user normally uses the ECG measuring device, the two electrodes are just adhered to the hands and the face of the user. The ECG measuring method of the present invention is to measure a first ECG signal from the left hand to the left side of face of the user and a second ECG signal from the right hand to the right side of face of the user. Then a plurality of ECG features are obtained from the first ECG signal, the second ECG signal and the result, as related coefficients, of the interactive computing, as a method of plus and subtract, of the first ECG signal and the second ECG signal. Hence, a biometric authorization process is engaged according to the plurality of ECG features.

  • Patent number: 8812090
    Abstract: A calibration method of electrocardiogram signals and the application program for the same. The method comprises steps of receiving an uncalibrated/unidentified electrocardiogram signal of a user, calculating the ratio of the distance length of an uncalibrated/unidentified electrocardiogram signal and the distance length of an electrocardiogram template, then generating a trigonometric value which corresponds with a trigonometric projection degree according to the ratio. Next step is to set a characteristic point of the uncalibrated electrocardiogram signal as an axis anchor point of the trigonometric projection for attaining a displacement. Lastly, perform the calibration on the unidentified electrocardiogram signal according to the generated trigonometric value which corresponds with trigonometric projection degree and the attained displacement. Then perform identification comparison of the unidentified electrocardiogram signal and the saved electrocardiogram template for further authorization.
