Abstract: A system, method, and device for amplifying the signal of a photodiode are provided. The exemplary system may have a photodiode with an amplifier. The amplifier may have an amplifier inverting input, an amplifier non-inverting input, and an amplifier output. A photodiode of the system may have a photodiode anode electrically connected with the amplifier inverting input and a photodiode cathode electrically connected with the amplifier non-inverting input. A gain resistor of the system may couple the amplifier inverting input with the amplifier output. The system may also have a fixed voltage reference electrically connected with the photodiode cathode and the amplifier non-inverting output.

Abstract: A trim pad assembly provides a cover to a watershield and a door frame of an automobile. The automobile includes a passenger compartment that is accessible through the door frame. The trim pad assembly includes an inboard decorative surface facing the passenger compartment when the door frame is in the closed position with respect to the automobile. The trim pad assembly also includes an outboard surface defining a periphery. The periphery is fixedly secured to the door frame. The trim pad assembly also includes a relief that extends about the periphery. The relief receives the watershield therein when the trim pad assembly is fixedly secured to the door frame such that the trim pad and the watershield prevent water from passing through the watershield and into and past the trim pad assembly.

Abstract: A door assembly includes a door frame having an outer door panel. A trim pad, having an inboard surface, is fixedly secured to the door frame. The trim pad defines an interior space between the trim pad and the outer door panel. An intermediate barrier is fixedly secured to the door frame between the outer door panel and the trim pad. The intermediate barrier has at least one side impact portion and a water-impervious outboard surface defining a periphery thereabout.
