20080267226 | Broadband fiber laser - A broadband fiber laser provides a lasing cavity including a reflective mirror and at least one fiber Bragg grating for further providing a lasing signal to resonate and be amplified therein. Alternatively, the wavelength of the fiber laser can be either fixed or tunable by varying the central wavelength of the fiber Bragg grating and/or by adjusting the switching status of an optical switch pair. | 10-30-2008 |
20100008386 | Broadband fiber laser - A broadband fiber laser provides a lasing cavity including a reflective minor and at least one fiber Bragg grating for further providing a lasing signal to resonate and be amplified therein. Alternatively, the wavelength of the fiber laser can be either fixed or tunable by varying the central wavelength of the fiber Bragg grating and/or by adjusting the switching status of an optical switch pair. | 01-14-2010 |

20150271891 | CONTROL METHOD OF COLOR TEMPERATURE AND LUMINANCE FOR LED DEVICE AND CONTROL SYSTEM THEREOF - The present invention is a control method of color temperature and luminance for an LED device and a control system thereof. The control method has the following steps: executing a cold-start motion; determining whether a warm-start motion is executed during a preset time; if yes, adjusting the color temperature of the LED device, and determining whether the warm-start motion is executed again during the preset time; if not, adjusting the luminance of the LED device, and determining whether the warm-start motion is executed again. A user can adjust the color temperature and the luminance of the LED device by turning off and on a switch of the control system. | 09-24-2015 |

20150285355 | Hollow Drive Gear Reduction Mechanism - A hollow drive gear reduction mechanism includes a hollow wave generator, an annular flexible bearing, a flexible wheel, and a rigid wheel. The annular flexible bearing is disposed in and driven to rotate by an elliptical recess of the wave generator. The flexible wheel includes an inner toothed section and is inserted in the annular flexible bearing and has an outer surface abutted against an inner surface of the inner ring, and the flexible wheel is driven to rotate by the annular flexible bearing. The rigid wheel includes a plurality of outer teeth which are different in number from the inner teeth of the flexible wheel, the rigid wheel is inserted in the flexible wheel, and a part of the outer teeth are meshed with the inner teeth. The respective components are hollow structures, and a lateral aperture is formed on the hollow wave generator. | 10-08-2015 |
