Patent ID: 8589034

Claim:
A system for an accurate calculation of a precise position and a display of a sun glare block area, and a display of a sunshield in a windshield in a transportation vehicle comprised of the following required components: a microcontroller, a memory and storage unit, a light sensor, a GPS unit, a digital clock, a digital compass, an inclinometer, a distance sensor, a position sensor, an input and control device, and the following optional components: power supply unit, microprocessor, and wherein the transportation vehicles comprises of automobiles, buses, light duty trucks, trucks, trains, and other road motor vehicles; and wherein the digital compass measures a compass North direction which is then converted to a true geographic North direction; and wherein the inclinometer monitors whether a road has an inclination or declination, and measures a slope of the road; and wherein the distance and position sensors measure a vertical distance between a driver's crown and a ceiling of the transportation vehicle and a horizontal perpendicular distance from a bottom edge of the windshield to a horizontal position of the driver's forehead; and wherein the memory and storage unit stores a vertical distance between the driver's crown and eyes entered by the driver or reverse calculated through a tuning mode; and wherein an eyes image position is determined from the vertical distance between the driver's crown and the ceiling of the transportation vehicle, the vertical distance between the driver's crown and eyes, and the horizontal perpendicular distance from the bottom edge of the windshield to the horizontal position of the driver's forehead; and wherein the microcontroller is configured to calculate the precise position of display of the sun glare block area and the sunshield based on the determined eyes image position; and wherein the light sensor monitors and measures a current ambient light intensity for a comparison with minimum ambient light intensity threshold values for the sun glare block area and the sunshield to trigger “on” or “off” for the display of the sun glare block area and the sunshield; and wherein the input and control device comprises of a required touch screen or pad wired on a dashboard, front or side panels, or a steering wheel of the transportation vehicle; and wherein the required components can be substituted with components that provide the same or similar measurements to be used in the calculation of the sun glare location on the windshield as viewed by the driver; and wherein the required components and the optional components are built as part of the transportation vehicle, embedded in the transportation vehicle, or added in the transportation vehicle as standalone components, devices or sensors.
