Abstract

A remote pyrotechnic ignition system includes a power supply for producing an electrical current in a transmitting induction coil to induce an electrical current in a receiving induction coil for igniting a pyrotechnic device. Thus, a wireless ignition communication section allows pyrotechnic mortars to be reused and substantially reduces set-up time by eliminating the wiring of fireworks normally required for a pyrotechnic production. Optionally, a capacitor is charged by the power source via a charging circuit and discharged via a firing circuit to produce the electric current in the transmitting coil in a pulse. The capacitor provides a two-stage firing safety feature. An electronic control device such as a circuit board may be mounted on the pyrotechnic device for controlling ignition of the pyrotechnic device and is especially useful in controlling ignition sequencing and overall ignition timing of a lift charge and burst charge of the pyrotechnic device.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Application Ser. No. 60 / 708,935 filed Aug. 17, 2005; the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The invention relates generally to a remotely controlled ignition system for pyrotechnic devices. More particularly, the invention relates to such a control system which is capable of wirelessly igniting pyrotechnic devices. Specifically, the invention relates to such a system where ignition is accomplished via electromagnetic induction.[0004]2. Background Information[0005]Ignition systems for fireworks or pyrotechnic devices are within three primary categories, namely manual firing, electrical firing and digital firing. Manual firing is the age-old process of igniting a fuse with a torch or some sort of hand lighter whereby a flame is the catalyst for igniting the fuse. In more recent decades, electrical firing has b...
