Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
98 words
A system for the projection on the windshield of a vehicle images representative of information, this system comprising: a converter means for transforming said information into luminous digital signals transmitted by a succession of discrete luminous sources; a series of bundles of optic fibers in which the end receivers of each one of the bundles can be illuminated by a corresponding luminous source; an image-forming means representative of said information, comprising an arrangement of end transmitters of the bundles of optic fibers; and a lens collimated to infinity for projecting said image on the windshield of the vehicle.
Claim 2
Independent Claim
98 words
A system for the projection on the windshield of a vehicle images representative of information, this system comprising: a converter means for transforming said information into luminous digital signals transmitted by a succession of discrete luminous sources; a series of bundles of optic fibers in which the end receivers of each one of the bundles can be illuminated by a corresponding luminous source; an image-forming means representative of said information, comprising an arrangement of end transmitters of the bundles of optic fibers; and a lens collimated to infinity for projecting said image on the windshield of the vehicle.
Claim 3
Dependent Claim
36 words
A system according to claim 1, in which the ends of each of the bundles of optic fibers are arranged in such a manner as to form a rod, the group of rods forming a ladder.
