How can I detect if a number box is active or inactive… I need to send 1 when numbers are running and 0 when numbers have stopped running

I have posted a part of the code… im using blob tracking to detect people and the patch will give me x, y and mass of each blob. So far I can track four blobs, which works fine.. my problem is that when no blobs are visible then the patch still display the last received x, y and mass of each blob.. I would like a 0 in all the number boxes when there are no blobs to detect.

another choice would be to detect if the number boxes are getting values in and then create a 1 and if no values are received then 0

basically I would like to start a wave fil with 1 and 0 to stop it with each blob
