Publication number: 20140191143Abstract: An optocoupler is disclosed including a receiving unit, a metal bump, a substrate, a transparent light guiding block, a light emitting unit, and a transmitting unit. The metal bump is formed on the receiving unit and connects to the substrate. The transmitting unit is electrically connected to the light emitting unit, so as to selectively control whether the light emitting unit to emit the light or not. The metal bump is utilized to connect the substrate with the receiving unit, and then the transparent light guiding block is utilized to cover the light emitting unit, so as to simplify the structure of the optocoupler.Type: ApplicationFiled: March 15, 2013Publication date: July 10, 2014Applicant: CAPELLA MICROSYSTEMS (TAIWAN), INC.Inventors: CHENG-CHUNG SHIH, YUNG-CHUAN CHUANG, CHIH-CHENG CHIEN

Publication number: 20130015356Abstract: A reflection sensing system comprising a body, an illuming module and a detecting module. The body is made of LCP. The illuming module includes a first accommodating space and an LED, and the detecting module includes a light detector. The first accommodating space is disposed in the body and has a first opening at one end. In the first accommodating space, the neighboring region relative to the first opening is parabolic or approximately parabolic. At an end at an inner side of the first accommodating space near the light detector, at least one cross-section near the first opening is not parabolic or approximately parabolic. The LED is disposed at the focus of the first accommodating space and aligned towards the first opening. The light detector of the detecting module is disposed in the body and generates a sensing signal after receiving light.Type: ApplicationFiled: December 14, 2011Publication date: January 17, 2013Applicant: CAPELLA MICROSYSTEMS (TAIWAN), INC.Inventors: Cheng-Chung Shih, Yung-Chuan Chuang, Chien-Chung Hsiao

Publication number: 20110148804Abstract: For overcoming a defect that a conventional surface capacitive touch panel is not capable of determining more than two touch points so that the surface capacitive touch panel is not capable of determining any multi-touch commands, a type of a multi-touch command is determined by detecting relative movements between touch points and corresponding intermediate points on the surface capacitive touch panel, where the relative movements may be indicated by relative distances or relative directions. Therefore, a bottleneck that the surface capacitive touch panel cannot be used for detecting a type of a multi-touch command may be overcome, and the surface capacitive touch panel may be widely applied for touch panels required to detect multi-touch commands.Type: ApplicationFiled: April 13, 2010Publication date: June 23, 2011Inventors: Shui-Chin Yeh, Yi-Sheng Hsu, Chun-Yi Wei, Chi-Chung Ho, Chao-I Chang, Yung-Chuan Chuang

Patent number: 5746033Abstract: A construction method for one-step grout fixed window frames on external walls of a concrete-structured building includes the following steps. A window frame including vertical and horizontal sections is fixed with vertical lining boards to the inner side of its vertical sections to form a window frame assembly, and is then supported on an upper supporting board which has been securely attached to a concrete template of an external wall of the building. Template sealing strips are separately attached to an exterior edge and an interior edge of the vertical sections and the upper horizontal section of the window frame assembly, so that a complete molding cavity is formed. Into this molding cavity the grouting concrete is grouted and the window frame is inlaid in the concrete after the concrete is set and the concrete templates are removed.Type: GrantFiled: August 15, 1995Date of Patent: May 5, 1998Inventor: Yung-Chuan Chuang

Patent number: 5231787Abstract: Stable Bobber for Rod Fishing consists of a stream-line conic rod with a plurality of proper holes at the side of its lower portion, or with two stream-line sections in reverse direction wherein one section is formed by cutting off its lower portion; these two kinds of bobber are either suitable for an open water region or for a close water region and are both very stable and sensitive. When the bobber is floating on the water and the color-striped post is affected by discontinual resistance force from waves and wind to oscillate and fall on the surface of water, the bobber can turn its stream-line to the proper direction and maintain itself upright and stable either by rotating itself to balance the back pressure or by gaining a negative pressure, and thus maintain its stability and sensibility.Type: GrantFiled: August 19, 1992Date of Patent: August 3, 1993Inventor: Yung-Chuan Chuang
