ABSTRACT:
A method for achieving zero, or near zero, latency timed pyrotechnic events by utilizing distributed processing is presented. A list of timed events may be used to synchronize a pyrotechnic firing sequence with music or other external events. This list is distributed over a series of embedded microprocessors. Each microprocessor is then synchronized to a master controller clock, and enabled such that each processor may then fire independently as required by the master list. This distributed process removes the split-second timing requirement from the main controller enabling the achievement of zero latency and providing significantly more timing events to be processed simultaneously while alleviating problems such as wireless radio interference delays. Each module is capable of forwarding information to other modules, which may be a position that prevents wireless communication directly with the master controller.
