Abstract
The disclosed device enables the user to verify the speed of their vehicle responsive to sensing that a radar device has been used to measure their speed. The device includes a radar detector designed to sense a radar beam. When the detector senses the beam, it activates a speed measuring device mounted on the vehicle which instantaneously measures the vehicle speed and then stores the measured speed for later display and for printing a permanent record, if desired.
Claims7
A system mountable in a vehicle for verifying vehicle speed, comprising:
- a) detector means for detecting signals indicative of nearby use of a speed measuring device, said detector means including alarm means for notifying a user of detection of said signals;
- b) transmitter means activated responsive to sensing of said signals by said detector means, for transmitting further signals away from said vehicle toward a stationary surface;
- c) receiver means for receiving reflected signals from reflection of said further signals off said stationary surface, said reflected signals being transmitted to a computer with memory;
- d) said computer with memory receiving said reflected signals and calculating and storing vehicle speed.
