  • Patent number: 7493859
    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.

  • Patent number: 5739462
    Abstract: A pyrotechnic device includes a launcher for launching and igniting a plurality of pyrotechnic stars for creating an aerial fireworks display. The launcher comprises a launching tube having an igniter that ignites the pyrotechnic stars as they are being expelled from the launching tube under the force of pressurized air. The igniter may comprise a section of the launching tube having a locally reduced diameter so that the pyrotechnic star frictionally engages it during launch, causing a striker composition on the interior of the launching tube to ignite a prime composition on the exterior surface of the pyrotechnic star. Alternatively, the igniter may comprise a flame within the launching tube to ignite the prime composition on the star. Various feeding mechanisms are provided to rapidly feed a large number of pyrotechnic stars for launching from the launching tube. The launcher utilizes pressurized air to launch the pyrotechnic stars and, thus, minimizes adverse environmental impact.

  • Patent number: 5627338
    Abstract: A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, a fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the projectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner.

  • Patent number: RE38592
    Abstract: A multiple effect pyrotechnic shell (20), having a lift chamber (22), primary break (24), secondary break (26), and a tertiary break (28) has a desired weight distribution to inhibit tumbling. The secondary break weight is less than the primary break weight, and the tertiary break weight is less than both the primary and secondary break weights. Thus, the center of gravity of the shell (20) is positioned below a midpoint of the shell height. A first timing fuse (46) extends from a lift charge (30) into a primary break charge (50A) of the primary break (24), and a primary internal timing fuse (64) extends from the primary break (24) to the secondary break (26). Further, a secondary internal timing fuse (70) extends from the secondary break (26) to the tertiary break (28). Fuse fragments (52) are preferably disbursed within the break hulls (48) to provide filler and add an additional effect to each break (24-28).
