A monolithically integrated field effect transistor and Schottky diode includes gate trenches extending into a semiconductor region. An optical connector is positioned in the opening, wherein the opening is configured to receive the optical connector therein without rotating the optical connector relative to the connector receiving portion. The leg is pivotally mounted to the inboard end of the seat cushion frame and includes a latch mechanism for securing to the vehicle floor. The DAS is coupled to the board and included an electronic part to perform signal processing for the electrical signal. Through repeated comparisons of arrival data developed from one carrier with arrival data previously developed and stored as to the other carrier, the one carrier is gradually slowed down as necessary to avoid a collision. The stopper head assembly further includes a stopper body operably coupleable to a control element to move the assembly between the drain position and the plug position.
