Remotely controlled ignition system for pyrotechnics

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...

AI Technical Summary

Problems solved by technology

The digital systems are very expensive and are typically used with pyro-musical productions.

While manual firing is still the least expensive method of igniting pyrotechnic devices, the manual firing method presents obvious safety issues from the inability to ignite the fireworks remotely.

The labor for wiring each of these E-matches to the firing system is very time-consuming and cumbersome, and results in many wires disposed above the firing mortars of the pyrotechnic devices.

It has been estimated that approximately half of the labor of setting up a pyrotechnic show is due to the wiring of these devices.
