<p>PURPOSE: To detect the rapid deceleration of an automobile automatically by providing a pulse generator that is operated by a speed measuring instrument of a vehicle and a signal transformer-amplifier and the like. CONSTITUTION: A pulse signal generated by a pulse generator 1 increases a voltage that is proportional to an input signal by a transformer 2 and is supplies to circuits 3. Then, the signal is inputted to a discriminator 4 via, for example, a conversion means rectification diode 10 consisting of two circuits 3 that is driven simultaneously by the secondary circuit of the transformer 2, where the circuit 3 consists of a capacity-resistance-type circuit, the output from the circuit 3 is cascaded to two input terminals A and B of the discriminator 4, and the capacity-resistance-type circuit supplies two signals with different strengths to the input terminals A and B of the discriminator 4. Also, when two signals with different plus/minus value and amplitude are received to the extent that a specific minimum threshold is exceeded, the discriminator 4 generates an output signal and excites a relay B for controlling a circuit for energizing an indicator 5, thus automatically detecting the rapid deceleration of an automobile.</p> |
