An injection-molded stator has a stator core, a coil winding having a head, an end insulating plate having a first groove, and a connector. The invention, discriminating the headlights and tail lamps from noise lights such as a traffic light, streetlight, and vending machine, enhances the vehicle detection performance at night. A bonding pad is formed above the resistor such that the serpentine pattern extends over the entire bond pad area. After ceasing to display the first window, the client system detects a second input that corresponds to a request to view content of the first window; and in response to detecting the second input, the client displays an interactive overlay that includes content of the first window and partially overlaps the display region.
