Abstract: The present invention comprises a bracket assembly that holds a lens and a circuit board with LED components therein, wherein the bracket assembly comprises an upper bracket, a protective cover, and a lower bracket. The bracket assembly is disposed between a goggle socket and a goggle lens cap such that the goggle socket is directly adjacent to the lower bracket and the goggle lens cap is directly adjacent to the upper bracket. The lens is disposed between the circuit board and the lower bracket such that the lens is biased toward the goggle socket. The position of the lens prevents reflections from the LED components. Additionally, the position of the lens allows it to be composed of light impeding material without impeding the emission of light from the LED components. Additionally, the circuit board is recessed within the goggle socket to increase the angular aperture of the goggles.

Abstract: A fuel system for an internal combustion engine comprises a fuel injection apparatus (16) including at least one fuel injector (18), the fuel injection apparatus (16) being arranged to inject fuel at high pressure into an associated combustion space, and a primary supply line (11) through which fuel is supplied from a low pressure reservoir (10) to the fuel injection apparatus (16). The system also includes a return flow line (20) for a return flow of fuel from the fuel injection apparatus (16) to the low pressure reservoir (10), and a filter arrangement (32) including a primary filter (14) arranged within the primary supply line (11) for filtering contaminants in the fuel flow through the primary supply line (11) and a secondary filter (30) arranged within the return flow line (20) for filtering contaminants from the flow through the return flow line (20).

Abstract: Empty component locations are detected on an assembled circuit board where the component locations are marked with spots of a fluorescent substance before assembly. The circuit board is exposed to stimulating radiation by a radiation source causing luminescence from the spots of fluorescent substance on which the stimulating radiation is impinged. The circuit board is then examined for the luminescence to determine whether the components are between the spots and the radiation source.
