Patent number: 8396281Abstract: A method for inspecting substrate internal defects is disclosed. The method provides at least one light source disposed on a lateral side of a substrate and configured to emit a light beam to the lateral side for correspondingly penetrating the substrate. The method also provides an image capturing module for retrieving an image of the upper surface, wherein an incident angle of the light beam to the respective lateral side is limited within a first predetermined angle to allow the light beam to have a total reflection in the substrate. Thus, the light beam is blocked by internal defects when transmitting within the substrate to generate bright spots to be detected by the image capturing module for locating the defect position. The method provides a better image definition of internal defects images. The present invention further provides an apparatus based on the method for inspecting substrate internal defects.Type: GrantFiled: March 25, 2010Date of Patent: March 12, 2013Assignee: Delta Electronics, Inc.Inventors: Jen-Ming Chang, Yu-Hsi Lee, Yen-Chun Chou, Cheng-Kai Chen, Jui-Yu Lin

Patent number: 8127276Abstract: Apparatus, method, and computer readable medium for generating and utilizing a feature code to monitor a program are provided. The program is run in a secure environment at the beginning. The program calls a function through an application program interface. A return address of the application program interface is used to generate the feature code. When the application runs again at another time, the feature code is utilized to monitor the program. According to the aforementioned arrangement and steps, the application program interface can be monitored dynamically. Consequently, any program can be monitored by this approach, which results in a more secure environment. Further, fewer application program interfaces are required to be monitored, so the required computer resource is less.Type: GrantFiled: April 3, 2007Date of Patent: February 28, 2012Assignee: Institute for Information IndustryInventors: Cheng-Kai Chen, Hung Min Sun, Kang-Chiao Lin, Shih-Ying Chang, Shuai-Min Chen
