Patent number: 8582926Abstract: A hand-held scanning system and method thereof are described. A look-up table is created to generate a mapping relation between a plurality of reference amplitudes and a plurality of corresponding sampled positions. An analog-to-digital converter samples an analog signal and converts it into a digital signal. The digital signal represents a mapping relation between the sampled positions of the movement distance and the corresponding scanning amplitudes of the signal intensity. The hand-held scanning system ascertains the sampled positions corresponding to a former scanning amplitudes and a present scanning amplitudes according to the look-up table during the scanning stage for detecting the position variation status to determine whether the trigger signal is activated for image scanning or not.Type: GrantFiled: May 4, 2011Date of Patent: November 12, 2013Assignee: Genesys Logic, Inc.Inventor: Mi-lai Tsai

Patent number: 8279196Abstract: A display device using a surface capacitive touch panel is proposed. Upon a normal mode, an external clock generator supports a clock source; meanwhile, an external clock generator, a signal generator, a current detector, a current-to-voltage converter, an analog-to-digital converter, a filter, an interface controller, a microprocessor, and the touch-position calculators are turned on. But under a power-down mode, the external clock generator, the analog-to-digital converter, filter, the interface controller, the microprocessor, and the touch-position calculators are turned off in order to reduce power consumption. Furthermore, the external clock generator is also turned off to minimize the power consumption.Type: GrantFiled: June 24, 2009Date of Patent: October 2, 2012Assignee: Genesys Logic, Inc.Inventor: Mi-lai Tsai

Publication number: 20100245894Abstract: A scanning device capable of directly sending scanned images to a printing device to be printed and a related method are proposed. An image information is obtained by scanning with an image sensor module, and then stored in a storage device. When a print client detects a print request, a storing server delivers the image information to the printing device through a picture transfer protocol. Accordingly, the image information is to be printed upon a direct link between the printing device and the scanning device without needing a computer serving as a bridge.Type: ApplicationFiled: September 16, 2009Publication date: September 30, 2010Applicant: Genesys Logic, Inc.Inventors: Mi-lai Tsai, Shang-wen Huang, Chih-kuang Hsu, Liang-yu Chang, Fu-Iiang Kao, Tsung-en Tsai
