VIOLATION ALERT SPEED DISPLAY
First Claim
1. A speed measuring and display device comprising:
- speed measuring means for providing a signal indicative of an object'"'"'s actual speed;
means for providing a signal indicative of a threshold speed preset by a user;
display means for exhibiting said signal indicative of said object'"'"'s speed in a readable form, said display means having a first mode for exhibiting the object'"'"'s speed in a first state and a second mode for exhibiting said object'"'"'s speed in a second accentuated state relative to said first state;
means for driving said display means and including logic means for comparing the object'"'"'s speed to said threshold speed, said comparing means providing a first mode to said measured speed upon the object'"'"'s speed not being above said threshold speed and a second mode upon the object'"'"'s speed being above said threshold speed, said driving means placing said display means in said first mode upon receipt of said first speed mode from said driving means or placing said display means in said second mode upon receipt of said second speed mode from said display means.

Abstract
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.

8. A vehicle speed measuring and display device comprising:
-
means for providing a signal indicative of a vehicle'"'"'s actual speed;
means for comparing said signal indicative of the vehicle'"'"'s measured speed with a signal indicative of a threshold speed desired by a user, said comparing means generating information indicative of whether said measured speed signal is greater than said desired threshold speed signal;
means for providing to said comparing means said signal indicative of the threshold speed;
a screen display for exhibiting said vehicle'"'"'s measured speed in a digital form, said display means having a first set of visual indicia of a first color and a second set of visual indicia of a second color adapted to display in a selectable pattern the digits 00 through 99 upon a selectable energization thereof;
means for energizing either said first set of visual indicia or said second set of visual indicia in said selectable pattern corresponding to the vehicle'"'"'s measured speed, said second set of visual indicia energized upon said information being generated by said comparing means whereby said screen digitally displays said second set of visual indicia upon said measured speed being greater than said threshold speed. - View Dependent Claims (9, 10, 11, 12)

13. A method for warning a vehicle driver of exceeding a speed limit comprising the steps of:
-
a. measuring the vehicle'"'"'s speed;
b. comparing the measured vehicle'"'"'s speed to a preselected speed limit;
c. determining whether the measured vehicle speed is not above the speed limit;
d. providing a screen for visually displaying the measured vehicle speed;
e. exhibiting the measured vehicle screen on said screen in a first display if said measured vehicle speed is not above the speed limit;
f. exhibiting the measured vehicle speed on said screen in a second accentuated display relative to said first display if said measured vehicle speed is above the speed limit. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
