Precision pyrotechnic display system and method having increased safety and timing accuracy

Abstract

A system and method are disclosed for controlling the launch and burst of pyrotechnic projectiles in a pyrotechnic, or “fireworks”, display.

1 .- 37 . (canceled) 
   
   
       38 . An ignitor for a pyrotechnic projectile of the sort comprising a lift charge to be ignited by an electrically operated lift charge ignition device, and a break charge to be ignited by an electrically operated break charge ignition device, said ignitor comprising:
 an electronic control unit for receiving an electronic fire command from an external control device and, in response thereto, (1) a first pre-determined time after receiving said electronic fire command, activating said electrically operated lift charge ignition device, and (2) a second pre-determined time after receiving said electronic fire command, activating said electrically operated break charge ignition device;   wherein said electronic control unit comprises: a first output connecting said ignitor to said electrically operated lift charge ignition device; a second output connecting said ignitor to said electrically operated break charge ignition device; a power supply for selective connection to said first output and said second output for selectively activating said electrically operated lift charge ignition device and said electrically operated break charge ignition device, respectively; and a timer for determining (i) when said power supply activates said electrically operated lift charge ignition device, and (ii) when said power supply activates said electrically operated break charge ignition device.
