ABSTRACT:
A new control circuit for firing an ultrasonic vertical anti-hail cannon on a repeated basis from a remote location. The control circuit employs a micro-controller with electrically erasable programmable read only memory and random access memory. When main power is provided the program is read from memory and several safety tests are run before the program goes into a routine that provides for repeated cannon firings. In the preferred embodiment a telephone pager is employed in the control circuit to enable repeated cannon fire by merely paging the cannon from a remote location. Likewise, the repeated cannon fire can be halted by paging the control circuit. The control circuit employs certain safety protocols to minimize the likelihood of inadvertent cannon fire and to permit manual firing and servicing of the cannon.
