  • Publication number: 20240161505
    Abstract: Provided is behavior image sensor system, including a first image capturing unit and a control unit. The first image capturing unit is used for capturing a moving image. The control unit is electrically connected to the first image capturing unit, receives the moving image, and calculates a moving track of a moving object in the moving image, thereby determining whether the moving track of the moving object conforms to a particularly dangerous behavior pattern. As such, the behavior image sensor system does not need to capture a static image of a static object completely and determine a behavior pattern of the static object, so that the behavior image sensor system may reduce the quantity of data a lot and is suitable for all kinds of environment.

    Abstract: The present disclosure provides a silicon carbide (SiC) opto-thyristor and a method for manufacturing the same. The SiC opto-thyristor includes a SiC substrate, a SiC light emitter and a SiC light-sensitive thyristor. In the method, a SiC epitaxy is mainly formed on the SiC substrate with the doped P-type and N-type semiconductor materials to define the regions for forming the SiC light emitter and the basic structures of the SiC light-sensitive thyristor. A passivation layer is deposited. Conducting channels for the SiC light emitter and the SiC light-sensitive thyristor are formed by an etching process. After patterning a metal conductor layer, a structure of electrical contacts of the SiC light emitter and the SiC light-sensitive thyristor is formed. Then, terminals of an input voltage and an output voltage of the silicon carbide opto-thyristor are formed after a wire bonding process upon the electrical contacts.
