Patent number: 9335525Abstract: An optical lens is configured in front of an image-capturing lens of an image-capturing device. A light-emitting unit of the image-capturing device emits a light beam. The optical lens includes a pair of peripheral compensation portions and a central diverging portion. Each peripheral compensation portion has a first convex surface and a first concave surface arranged opposite to the first convex surface. The central diverging portion is arranged between the peripheral compensation portions, and has a second concave surface and an oppositely arranged light incident surface. The second concave surface is arranged between the first convex surfaces. The light incident surface is arranged between the first concave surfaces. The optical axis of the light beam sequentially aligns with the light incident surface and the second concave surface. The light rays of the light beam pass through the first concave surface and the first convex surface in sequence.Type: GrantFiled: September 27, 2013Date of Patent: May 10, 2016Assignee: PIXART IMAGING INC.Inventors: Yu-Hsiang Huang, Chun-Yi Lu, Tzung-Min Su, Chih-Hsin Lin, Jia-Hong Huang

Patent number: 9081456Abstract: A capacitance detection apparatus for a touch panel includes an N number of capacitors. The detection apparatus generates an N number of different input signals, and provides an ith input signal of the input signals to an ith capacitor. The N number of input signals correspond to a delayed sequence of a maximum length sequence or the maximum length sequence. The detection apparatus sums up an N number of response signals, which are generated after providing the N number of input signals to the N number of capacitors, to generate a summed signal. The summed signal is multiplied by the ith input signal and integrated to generate an ith integrated signal. The detection apparatus estimates capacitance values of the N number of capacitors according to the N number of integrated signals, respectively.Type: GrantFiled: October 28, 2013Date of Patent: July 14, 2015Assignee: MSTAR SEMICONDUCTOR, INC.Inventors: Yu-Che Su, Jia-Hong Huang, Wen-Chieh Yang, Tai-Lai Tung
