    • PURPOSE:To perform detection in a shock and an abrupt acceleration state by generating a warning when the set voltage S of limit frequency (f) of N-divided limits of practical use becomes equal to the output of a differentiating circuit. CONSTITUTION:A signal 2 before being divided is passed through plural differentiating circuits in series. The level S of the voltage corresponding to the frequency (f) of the dividable, i.e. usable limit of an N-dividing circuit is set previously. Then, the output E1''' of the tertiary differentiating circuit is compared with the set voltage S by a comparing circuit all the time to detect the limit of division when E1''' becomes equal to S, generating a warning.
    • 目的:当实际使用的N分频极限频率(f)的设定电压S等于微分电路的输出时,通过产生警告来进行冲击和突然加速状态的检测。 构成:分割前的信号2通过多个微分电路串联。 预先设定与可分割的频率(f)对应的电压的电平S,即N分频电路的可用极限。 然后,通过比较电路将三次微分电路的输出E1“'与设定电压S进行比较,以在E1”等于S时检测分频极限,产生警告。

    • PURPOSE:To make acceleration display accurately and easily visible, by consisting the titled apparatus of a car speed sensor, a differentiation circuit for detecting acceleration, a peak hold circuit for holding the output limit value of said differentiation circuit for a definite time and a display apparatus for displaying the output thereof. CONSTITUTION:A pulse detected by a car speed sensor 1 is converted to a voltage form by a F/V converter 2. A differentiation circuit 3 differentiates the output of the F/N converter 2 and outputs a speed change amount per a unit time. The plus portion of the speed change amount is sent to a peak hold circuit 4 while the minus portion thereof is sent to a collision detecting circuit or the like not shown by the drawing. The peak hold circuit 4 holds max. acceleration for a definite time and thereafter sends display output to a display device. The voltage differentiated by the differentiation circuit 3 is branched and one is connected to a non-reversible input terminal of a comparator 2 as well as connected to the display device 5 as display output while the other is connected to the reversible input terminal of the comparator 2. By constituting the titled apparatus as mentioned above, acceleration display can be made accurately and easily visible.
