Abstract
A frequency addressable ignitor control device utilizes electronic bandpass filters tuned to a unique center frequency and bandwidth for each ignitor. Energy generated by the system's controller comprises one or more narrow pulses whose center frequency corresponds to one or more bandpass filter/ignitor assemblies and sufficient energy for activation. A plurality of bandpass filter/ignitor assemblies are connected in parallel in the system. The controller generates electrical pulses of different frequencies transferred to the plurality of bandpass filter/ignitor assemblies via a two wire ignitor bus. Bandpass filter/ignitor assemblies whose filter allows sufficient energy to pass to an ignitor bridge element initiates the ignitor's explosive charge. The controller generates energy to the ignitor with appropriate sequence of frequencies and delays resulting in the desired detonation of appropriate individual bandpass filter/ignitor assemblies in the desired sequential order each with the desired delays.
