First Claim
Patent Images
1. A night vision system for a vehicle comprising:
- a first light source for illuminating a region proximate the vehicle, said light source generating a first night vision pulse signal;
a light sensor receiving a second night vision pulse signal from an approaching vehicle, wherein said second night vision pulse blinds said first night vision pulse signal;
an electronic compass comprising zones comprising dominant zones and recessive zones,an electronic compass comprising zones comprising dominant zones and recessive zones; and
a controller shifting pulses from said first night vision pulse signal in a different direction than pulses from said second night vision pulse signal until an anti-blinding of said first night vision pulse signal by said second night vision pulse signal is achieved, wherein said controller synchronizes said first night vision pulse signal with a timing signal of said second night vision pulse signal during said anti-blinding.

Abstract
A night vision system for a vehicle includes a first light source for illuminating a region proximate the vehicle, the light source generating a first night vision pulse signal. The system further includes a light sensor receiving a second night vision pulse signal from an approaching vehicle, wherein the second night vision pulse blinds the first night vision pulse signal. A controller shifts pulses from the first night vision pulse signal in a different direction than pulses from the second night vision pulse signal until an anti-blinding of the first night vision pulse signal by the second night vision pulse signal is achieved.

9. An anti-blinding method for a vehicle comprising:
-
generating a first light pulse train from the vehicle; detecting a second light pulse train from a second approaching vehicle blinding said first light pulse train from the vehicle; determining dominant zones and recessive zones on an electric compass, whereby said dominant zones include said second light pulse train and said recessive zones include said first light pulse train; and shifting said first light pulse train by increments until anti-blinding is achieved through offsetting said first light pulse train from said second light pulse train. - View Dependent Claims (10, 11, 12, 13, 14)

15. An anti-blinding method for a first vehicle approached by a second vehicle comprising:
-
generating a first light pulse train from the vehicle; detecting a second light pulse train from the second vehicle blinding said first light pulse train from the vehicle; determining dominant zones and recessive zones on an electric compass, whereby said dominant zones include said second light pulse train and said recessive zones include said first light pulse train; synchronizing a timing signal of said first light pulse train with a timing signal of said second light pulse train as a function said dominant zones and said recessive zones; and shifting said first light pulse train by increments until anti-blinding is achieved. - View Dependent Claims (16, 17, 18)
