Speed limit alarm for motor vehicle |
| abstract |
The alarm includes a sensing unit (Figs. 2 and 3, not shown) connected to the vehicle speedometer cable to emit a series of electrical pulses whose frequency is dependent on vehicle speed. Circuitry receives these pulses and includes a frequency to voltage converter whose output is applied to a network of comparators IC2B each receiving a respective reference signal representative of a respective set speed. The output of such comparator is fed to a gate circuit which switches an alarm device on and off as the speed of the vehicle passes through each selected speed limit for both increasing and decreasing speed of the vehicle. The sensing unit preferably includes a rotor (8) with a series of holes (14) rotating passed a light emitting diode (17) and a phototransistor (18). <IMAGE> |
