Definitions

  • one or more zone of activatable material is activated to shield their eyes from the direct or reflected rays of the sun, but without substantially blocking the field of vision of the driver. This is done continuously and dynamically as the vehicle and the sun change their position relative to one another, so that the shading is always positioned to shield the eyes.
  • the individual zone size is from about 0.1 inch to about 0-5 inch in length, and from about 0.1 inch to about 0-5 inch in width, with minimum spacing between zones.
  • photo transistors are preferred to CdS photo-resistors due to the faster response which the photo transistors have, however, any type of photocell is within the scope of the present invention.
  • the relay 72 of both photocell circuits 70 remains dosed, sending the same (+) current to the motor, so no rotation occurs.
  • one of the opposing photocells falls in the shadow of the aiming tube 68, it causes it's circuit 70 to send the opposite form of current (-), from power source 76 to motor 74, causing motor 74 to rotate in a first direction to move targeting tube 68 toward the sun 14.
  • relay 72 of the other photocell circuit 70 is tripped. This creates a complete circuit with the opposite direction, from power source 76 to motor 74, causing motor 74 to rotate in the opposite direction to aim targeting tube 68 toward the sun 14.
  • the central photocell 64 is struck by sunlight it causes the central circuit relay to switch and break the power circuits to the remaining circuits, thereby halting rotation of targeting member 60.
  • the rotation of motor 74 is transferred by way of pulleys or gears 78, and screw drive 82 to cause targeting member 60 to rotate in a direction corresponding to the movement of the sun 14 relative to the window 16.

Abstract

L'invention permet de protéger les yeux (12) des occupants d'un véhicule (18) des rayons directs du soleil ou des reflets (14) qui pénètrent à travers le pare-brise (16). Le dispositif est constitué d'une enveloppe normalement transparente (20) accolée au pare-brise (16). L'enveloppe comprend une couche normalement transparente de cristaux liquides activables conçue pour pouvoir adapter de manière sélective ses propriétés de transparence en fonction des signaux transmis par un champ électrique. Un dispositif (42) permettant d'établir la position du soleil transmet des signaux afin de communiquer la position du soleil (14) par rapport au pare-brise (16). En réponse à ces signaux, un champ électrique est appliqué à des points sélectionnés (32) de la couche normalement transparente de cristaux liquides activables afin d'activer et de modifier les propriétés de transparence de ces points. Ainsi, il est possible de protéger de manière sélective les yeux (12) des occupants d'un véhicule (18) des rayons directs du soleil ou de ses reflets.
