Abstract
An automobile deceleration indicating device includes a signal generation unit which is coupled to the engine system for generating a signal of which the frequency is in general proportional to the operation speed of the engine, an amplifying circuit for amplifying the signal from the signal generation unit, a shaping circuit for generating a series of pulses from the amplified signal so that the frequency of the pulses representing the operation speed of the engine, and a micro-processor based circuit which receives the pulses and applies a control signal to the stoplight via power amplification circuit when the frequency of the pulses is decreased which indicates that the engine is slowed down.
Claims2
An automobile deceleration indicating device comprising signal generation means for generating a first signal comprising a number of waves having a frequency representing operation speed of the moving parts of the automobile and control means for generating a second signal in response to the first signal in order to provide a visual warning, the control means comprising:
- amplifying means for receiving and amplifying the first signal and providing an amplified signal;
- waveform shaping means for shaping the waves of the amplified signal in order to provide a series of pulses that have a frequency representing the operation speed of the moving parts of the automobile;
- and
- processing means which receives the pulses and generates the second signal in response to a decreasing of the frequency of the pulses and wherein an output signal from a pulse signal generating unit comprising a magnet core surrounding a high voltage ignition cable of said automobile is sent to said deceleration indicating device.
