Abstract: A rearview truck mirror and wiper assembly for improving the rear view for truckers by keeping the mirror clean and lighted.

Abstract: There is provided a block (100) comprising a front wall (110); a rear wall (130); first side wall (115); second side wall (120) opposed to said first side wall (115); an upper block planar surface (140); a lower block planar surface (141); wherein said first side wall (115) and said second side wall (120) extend from said front wall (110) to said rear wall (130) to define a central through core (150) extending through the block (100) from said upper block surface (140) to said lower block surface (141), said core (150) having a front upper rim and a first front corner at the plane of said upper block surface, proximate intersection of said first side wall and said front wall; a first lug which extends downwardly from said lower block surface adjacent said first side wall, and has (i) a flat side portion flush with said first side wall and (ii) a front portion which joint said first lug side surface at an angle of 90° or less.

Abstract: A fingerprint optical input apparatus comprises a contact image sensor for viewing a moving finger and providing a high contrast image. A narrow strip of the fingerprint touching a transparent platen is illuminated by sheet of collimated light normal to or at an oblique angle to the surface. The fingerprint image is viewed at an oblique angle by partially scattered light or by frustrated total internal reflection by a GRIN rod lens array and projected onto a linear array sensor. Various embodiments of the platen provide a compact design by using TIR or mirror reflections of the fingerprint image.
