Fireworks launcher
InactiveUS6286429B1Reduce manufacturing costProvide strengthRocket launchersFirework flares/torchesFireworksEngineering
A longitudinal launcher tube made substantially of polyurethane resin or plastic having a rear end closed by a transverse rear wall and an open front end. The invention allows a projectile to be housed in the tube and adapted to slide longitudinally inside it towards the front, to be expelled from it via the front end tube, means for defining with the tube and projectile a rear gas expansion chamber immediately to the rear of the projectile, and an impulse cartridge adapted on command to develop gas pressure in the rear chamber to cause the expulsion of the projectile via the front end of the tube. The apparatus is a pyrotechnic device for rigidly supporting fireworks such as mortar-type, rocket-type, projectile-type, and other pyrotechnic devices so that the launcher device is reusable, whereby the launcher substantially retains its integrity after each launch to minimize harm caused to persons and the environment.

System and method for zero latency distributed processing of timed pyrotechnic events
ActiveUS7493859B2Energy optimizationZero delayAmmunition projectilesIncandescent ignitionMaster controllerLatency distribution
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.
