This circuit appeared in Electronics magazine more than 35 years ago:http://filecloud.io/9ka07n6j
Its function is similar to the circuit "Anti Car jack system" that can be found in the section EFY Magazine Projects. The latter circuit appeared in 2012. The fact that both circuits, one from 1976 and the other from 2012, are based on the 555 timer, shows how useful this IC is. Its designer, Hans Camenzind, passed away recently.
