摘要： A method includes flowing gases including combustion byproducts past an exposed face of an optical element in an engine fluid conduit, and depositing debris on the exposed face of the optical element. The debris may be soot, unburned hydrocarbons, sulfates, and/or a reductant precipitate. The method further includes passing electromagnetic (EM) radiation through the optical element and the flowing gases and interrogating the EM radiation after passing through the optical element and the flowing gases to determine an amount of debris accumulated on the exposed face of the optical element. The method further includes heating a resistive wire thermally coupled to the optical element sufficiently to remove accumulated debris from the exposed face in response to the amount of debris exceeding a threshold.

摘要： A multi-layer rigid prototype printed circuit board is fabricated by applying a heat activated, rapid setting or tacking melt-remelt adhesive utilizing a moderate temperature heat laminating device onto appropriate surfaces of pre-etched and plated insulative film based, flexible film layers. A computer guided drill drills through-holes within an electrical insulative material planar substrate core using prescribed drill sizes for each through-hole pin size desired for a given hole location. The etched layers with the adhesive applied are positioned in proper sequence aligned to the drilled hole pattern and heat laminated thereto as a stacked array on the top and/or bottom surfaces of the substrate core. Computer guided drilling of the adhered films with prescribed smaller drill sizes at each through-hole location is effected to create film cantilever portions extending radially outwardly of the edge of the through-holes. Unique, polygonal or like cross-section through-hole connector pins are inserted into the aligned holes within the flexible film layers and the substrate, with the pins having at least one radial projection forming a sharp corner which cuts into the conductor tracks of the multi-layer flexible film array to deflect and deform the cantilever edge portion of the multi-layer flexible films into the substrate through-holes for effecting a low impedance conductor track to pin to conductor track electrical connection for a plurality of the films. The conductor tracks at the cantilever edge portions may be provided with a solder film and heat applied by post-heating the through-hole connector pins or otherwise to facilitate a low impedance connection between the periphery of the through-hole connector pin and the conductor tracks of the multi-layer flexible film array. The application of heat remelts the adhesive facilitating flexing of the multi-layer flexible films and ensuring contact between the conductor tracks and the pin periphery.
