An optical device. A lens module is movably disposed in a lens housing. A drive mechanism is connected to the lens module, driving the lens module along an optical axis of the lens module. A brake mechanism is disposed between the lens housing and the lens module and moves perpendicular to the optical axis, fixing and releasing the lens module. When the brake mechanism releases the lens module, the lens module moves along the optical axis.

The present invention provides a photoelectric device, including a photoelectric semiconductor thin film having a light facing surface and a back light surface; and a photoelectric converter having a medium and photoelectric converting particles mounted on the medium, wherein the photoelectric converter is disposed at an outer side of the light facing surface of the photoelectric semiconductor film for absorbing and converting solar energy so as to enhance photoelectric conversion efficacy. The photoelectric converter absorbs the wavelength that the photoelectric semiconductor thin film cannot absorb, and emits the frequency band that the photoelectric semiconductor thin film can absorb. Thus, the photoelectric device of the present invention decreases the interference of light absorption, increases the light emission, eliminates the wastes of incident light, and increases the photoelectric conversion efficacy. Hence, the fabrication method of the solar cell is simplified, and the cost is decreased in the present invention.

A system and method for evaluating cardiovascular performance in real time and characterized by conversion of a surface potential into multi-channels are introduced. The system includes an electrocardiographic signal measuring unit, a reconstruction unit, and a parameter computation and assessment unit. The reconstruction unit reconstructs electrocardiographic signals (ECG signals) recorded by the electrocardiographic signal measuring unit, such that the ECG signals are reconstructed as ones located at different spatial positions but actually not having a channel. The method includes calculating a variation manifested spatially during an interval between a Q wave and a T wave of an ECG signal against time with a parameter computation and assessment algorithm, to evaluate its discreteness degree and thereby diagnose cardiovascular diseases (CVD) and locate lesions thereof.
