Patent number: 10250503Abstract: A routing method for a wireless mesh network and a wireless node performing the method are provided. The method includes performing a route algorithm and finding available paths to reach a destination node, recording the available paths, a parent-child node relationship, and a link-state in a route table, and transmitting or transferring data by using an optimal path among the available paths. The method also includes selecting another available path as the optimal path when the optimal path is not operable, updating the route table, and notifying a parent wireless node. The method further includes performing a block route algorithm when receiving a node-added message for creating a block route table in a block where the newly-added node belongs, updating the route table according to the block route table for acquiring updated available paths, selecting one of the updated available paths as the optimal path, and notifying the parent wireless node.Type: GrantFiled: December 20, 2016Date of Patent: April 2, 2019Assignee: Industrial Technology Research InstituteInventors: Chang-Hsien Chen, Kuan-Jen Fang, Yi-Cheng Chung

Patent number: 9798435Abstract: Disclosure is related to a touch-sensitive panel apparatus, a control circuit, and a method for scanning touch event. The method is generally adapted to sensing a touch event when a touch object is used to contact a touch-sensitive panel device. The method in the beginning includes performing a time-division scanning process for separately scanning a first sensing region and a second sensing region according to a scanning timing scenario. After that, a triggering zone may be sensed when the scanning process finds a touch event. A full-time scanning process is then performed to the triggering zone. A touching position may be determined according to the scanning process. In one further embodiment, the method then verifies an operating frequency for the touch event so as to confirm a triggering event.Type: GrantFiled: October 19, 2013Date of Patent: October 24, 2017Assignee: Wacom Co., Ltd.Inventors: Chang-Hsien Chen, Chih-Hung Huang

Publication number: 20150331504Abstract: Disclosure is related to a method for sensing fast motion, a controller, and a related electromagnetic sensing apparatus. The method is applicable to a touch panel, in which a fast scan mode is introduced when a fast motion made by an electromagnetic stylus is sensed under a partial scan mode. Therefore, the scan mode is switched to the fast scan mode which is used to acquire coordinates of the stylus according to the electromagnetic signals generated by the stylus. After that, the process goes back to the partial scan mode for continuously sensing the location of the electromagnetic stylus, and determining any fast motion behavior. In one embodiment, in order to obtain the coordinates of the stylus when its moving rate exceeds a threshold, a moving direction may be firstly determined. The one or more sensing loops may be opened in the direction of movement.Type: ApplicationFiled: August 28, 2014Publication date: November 19, 2015Inventors: CHANG-HSIEN CHEN, CHIH-HUNG HUANG
