Patent number: 9123934Abstract: A portable electronic device includes a main body, a battery, and a battery fixing mechanism including a button disposed through a button hole of the main body, first and second rod members, a first linkage rod pivoted to the first rod member and disposed in an oblique slot of the button, first and second transverse elastic members, and a rail member having transverse, oblique, and incurve rails. When a protruding rod of the first rod member moves in the transverse, oblique, or incurve rail, the rail member moves longitudinally to make the first rod member move transversely to be engaged with or separated from a first fixing hole of the battery. The first and second transverse elastic members are respectively disposed on the first and second rod members. The second rod member abuts against the first rod member for pushing the first rod member when the button is pressed.Type: GrantFiled: May 12, 2013Date of Patent: September 1, 2015Assignee: Wistron CorporationInventors: Jyun-Shuo Liang, Chu-Cheng Yang, Ming-Lun Liu, Yu-Sheng Lin, Hung-Li Chen

Patent number: 7761744Abstract: The invention provides a debugging method applicable for an embedded system. The system includes a processor, a main memory and a debugging interface. A debugging program is first provided in the main memory. A debugging interruption is subsequently triggered to cause the processor to read the debugging program from the main memory and execute the debugging program. After execution, an execution result of the debugging program is stored into the main memory. The execution result is read and output via the debugging interface for further analysis. Because the architecture does not require a scan chain of ITR 104, the circuit requirement is reduced while performance is increased.Type: GrantFiled: May 14, 2007Date of Patent: July 20, 2010Assignee: Industrial Technology Research InstituteInventors: Chao-Hung Chang, Po-Chou Chen, Ming-Lun Liu
