Make Timer in Simulink

Hello. I have 1 or 0 Signal coming as a input from my Ultrasonic Sensor. I want to make a Timer in simulink so that, if my input is 1 continuous for 5 seconds ,it gives me 1 at end, if not the timer starts again ,when 1 comes from the Sensor. I have Speed of Car and my distance. I wanted to integrate the distance to get time. Thankyou so much.

You can use Timer APIs to access timers programatically. Here's a link to the documentation.

It might be easier to implement it through Simulinnk block diagram, similar to this one.

Thankyou. I also used Integrator (Discrete) with reset to 0, if the conditon doesnot match and if condition match then compare to 10 for 10 seconds.
