  • Shielding structure for ultra-high voltage semiconductor devices
    Patent number: 11923425
    Abstract: A method for manufacturing a device may include providing an ultra-high voltage (UHV) component that includes a source region and a drain region, and forming an oxide layer on a top surface of the UHV component. The method may include connecting a low voltage terminal to the source region of the UHV component, and connecting a high voltage terminal to the drain region of the UHV component. The method may include forming a shielding structure on a surface of the oxide layer provided above the drain region of the UHV component, forming a high voltage interconnection that connects to the shielding structure and to the high voltage terminal, and forming a metal routing that connects the shielding structure and the low voltage terminal.

  • System and method of detecting abnormal segments of video
    Patent number: 8660343
    Abstract: A system and a method of detecting abnormal or security-significant segments of a video are provided. The video is divided into several segments. A set of features of each segment of the video is extracted in order to calculate a set of factors corresponding to each segment. A value deemed abnormal of each segment is calculated according to the set of factors corresponding to each segment. One or more abnormal segments are determined from the segments based on the abnormal values. The set of features includes a color variable feature, a movement variable feature, a movement variable ratio feature and a background variable feature.
