VIOLATION ALERT SPEED DISPLAY |
摘要 |
A speed display device for focusing a motorist's attention on the vehicle's speed, includes a screen which will digitally display thereon the vehicle's radar measured speed in either a first steady state at one color or in a flashing state at a second color. An internal microprocessor compares a preset threshold speed with the vehicle's measured speed. If the measured vehicle's speed is not greater than the threshold speed, the measured speed is screen displayed by energization of a first set of amber lights in a pattern according to the measured speed. If the measured speed is above the threshold speed, a second set of red flashing lights is energized in an accentuated pattern according to the measured speed. The device focuses the motorist's attention on the vehicle speed per se, particularly when above the threshold limit.
