The first transistor has a control terminal, a first terminal, and a second terminal. The second transistor is coupled to the control terminal. The third transistor is coupled to the control terminal and the second terminal. The light sensor is coupled to the control terminal. The capacitor is coupled to the control terminal. The fourth transistor is coupled to the second terminal.

Abstract: A head up display (HUD) includes a housing having an opening, a transmission mechanism disposed in the housing, a cover connected to the transmission mechanism and a drive mechanism configured to drive the transmission mechanism. The cover is movable between a closed position wherein the cover hides the opening and an opened position wherein the cover is located within the housing by the transmission mechanism. While the cover moves from the closed position to the opened position, the cover moves to an intermediate position below the opening in a vertical way, and moves away from the intermediate position below the opening to the opened position in sequence.

Abstract: A mounting structure of an interface jack includes an insulating housing, multiple electrical wires, a first metallic piece, a second metallic piece, and at least one third metallic piece. The insulating housing has an upper surface, a lower surface, a backside surface, a first lateral wall, a second lateral wall and an entrance. The entrance is communicated with a receptacle disposed within the insulating housing. The backside surface is connected with the upper surface, the lower surface, the first lateral wall and the second lateral wall. The electrical wires are arranged inside the insulating housing and extended out of the backside surface of the insulating housing. The first metallic piece is attached on the bottom surface of the first lateral wall. The second metallic piece is attached on the bottom surface of the second lateral wall. The third metallic piece is attached on the lower surface.
