Patent number: 8704535Abstract: The present invention relates to a layout for antenna loops having both functions of capacitance induction and electromagnetic induction, and particularly relates to the layout for antenna loops having both functions of capacitance induction and electromagnetic induction, wherein the capacitance detection elements are integrated with the antenna loops. In this layout for antenna loops, each of the antenna loops therein is separated into three sections, and there are several geometric structures fabricated in two of these sections. These geometric structures are capacitance detection elements. Therefore, the two sections are directly fabricated to be the capacitance detection elements because of these geometric structures. By this way, the antenna loops can be integrated with the capacitance detection elements and the capacitance detection elements do not prevent the antenna loops from receiving the electromagnetic signals.Type: GrantFiled: October 14, 2010Date of Patent: April 22, 2014Assignee: Waltop International CorporationInventors: Wei-Chou Chen, Ke-Wei Chen, Chia-Te Huang

Patent number: 7896765Abstract: The present invention relates to a belt tension adjustment mechanism for use with a device including a main body and a belt pulley set. The belt pulley set includes a belt. The belt tension adjustment mechanism includes a slab, at least two tension pulleys and a fixing element. A tight tension force and a slack tension force are exerted on the opposite sides of the belt to define a tight side and a slack side of the belt when the belt pulley set runs. A counterforce is generated from the tight side of the belt to exert on the tension pulley contacting with the tight side, the slab is moved in response to the counterforce. The slack side of the belt is suppressed by the tension pulley contacting with the slack side such that the slack tension force is adjustable.Type: GrantFiled: February 1, 2008Date of Patent: March 1, 2011Assignee: Teco Image Systems Co., Ltd.Inventors: Ping-Hung Kuo, Cheng-Ming Liao, Ke-Wei Chen, Yu-Pang Chen, Chien-Min Chen, Hsiu-Hui Chiu

Publication number: 20100271300Abstract: A multi-touch pad control method is disclosed. The method comprises the following steps. First of all, a primary cursor is detected. Then a first touch motion is detected, if there is no first touch motion, primary cursor is re-detected. Next a secondary cursor is detected if there is a first touch motion. Then a second touch motion is detected. A first function is performed if there is no second touch motion. A first direction of the second touch motion is detected, if the second touch motion controlling the secondary cursor is detected. A second function is performed if the second touch motion is toward first direction. A second direction of the second touch motion is detected, if the second touch motion is not toward the first direction.Type: ApplicationFiled: October 15, 2009Publication date: October 28, 2010Applicant: WALTOP INTERNATIONAL CORPORATIONInventors: Chung-Wen Hsu, Ke-Wei Chen
