Patent number: 7663767Abstract: An apparatus and a method are proposed for measuring displacement, surface profile and roughness of a moving object or an inner radius of a hollow cylinder. The apparatus includes a light emitting unit, a light dispersing unit for receiving light from the light emitting unit and focusing rays with different wavelengths into different focal points with different intervals, and a wavelength measuring unit for measuring wavelengths of the rays. When the moving object is moving within a dispersing range of the focal points, the rays with different wavelengths are reflected or scattered, and the displacement of the moving object is learned from variation of the wavelengths being measured by the wavelength measuring unit. Given that a reflecting component is disposed in the centre of an inner circle of the hollow cylinder, the inner radius of the hollow cylinder can be measured by the principle of the apparatus for measuring displacement.Type: GrantFiled: August 1, 2008Date of Patent: February 16, 2010Assignee: Industrial Technology Research InstituteInventors: Hong-Xi Cao, Jen-Chuen Liao, Ricky Hsu, Sheng-Jang Cheng, Ji-Bin Horng

Patent number: 7638744Abstract: The system for stabilizing wavelength of LED (light emitting diode) radiation in backlight module of the LCD (liquid crystal display) comprises two photodiodes, a plurality of LEDs, a microprocessor unit (MCU) and a driver circuit, wherein two photodiodes have different photo sensitivities in response different wavelengths. A target value, associated with a ration of photo sensitivities of the two photodiodes under two different wavelength radiations, is stored to the MCU as a referred value. Thus, another wavelength (or wavelength variation) of LED radiation is derived by comparing another target value with the referred value. The MCU determines a correction constant based on a color match function of the derived wavelength, and outputs a compensation signal to compensate LED, wherein the compensation signal is equal to multiplication of the correction constant and an original light intensity compensation signal for compensating light intensity loss of the LED.Type: GrantFiled: December 27, 2007Date of Patent: December 29, 2009Assignee: Industrial Technology Research InstituteInventors: Zhi-Xian Huang, Hong-Xi Cao, Kun-Chieh Chang, Fu-Shun Ho, Chun-Chieh Yang
