Publication number: 20130192486Abstract: Some of the most advanced fireworks displays incorporate music, video, lights, and other special effects. For the seamless operation of these displays, the presence of computerized firing systems on the market can be greatly appreciated. In addition to entertainment value, the abilities of initiating a fireworks display from a distance and being able to stop a display at any time has made shooting fireworks displays safer than ever. However, because of the expense of this hardware, these elaborate displays can be far out of reach for anyone who has a lower budget. The idea outlined in this patent will help solve that issue by suggesting an asynchronous computerized firing system. This system can be initiated using a personal computer without any proprietary hardware with the exception of low cost modules.Type: ApplicationFiled: January 27, 2012Publication date: August 1, 2013Inventor: Brian Ruggiero

The initiator is electrically connected to the capacitor, the transformer is mechanically and electrically connected to the capacitor and the addressable chip is mechanically and electrically connected to the transformer. The initiator may be bonded or fused to the capacitor, and the transformer may be bonded or fused to the capacitor. The capacitor, initiator, transformer and addressable chip form a unified integrated detonating unit.Type: GrantFiled: October 6, 2004Date of Patent: January 10, 2012Assignee: Schlumberger Technology CorporationInventors: James E. Brooks, Nolan C. Lerche, Anthony F. Veneruso

Publication number: 20110308415Abstract: An electronic programming system is for programmable ammunitions “M” implemented in a firearm (1). The system is adapted to send information to a detonating fuse of an ammunition “M”, which stores the information inside it, and is adapted to receive information on the characteristics of the ammunition “M” from the detonating fuse. The programming system is directly implemented inside a firearm 1, including at least one firearm-control unit 2, adapted to control all the systems implemented in the firearm 1. The electronic programming system includes at least one actuation mechanism 4, adapted to provide an electrical coupling between the detonating fuse and the programming system, and a programmer-control device 3, which, via appropriate interfaces, manages the data flows for communication both with the detonating fuse and with firearm-control unit 2.Type: ApplicationFiled: June 21, 2011Publication date: December 22, 2011Applicant: OTO MELARA S.p.A.Inventor: Andrea Bruschi

Patent number: 8065960Abstract: The invention relates to a hand grenade (1) with an active body (3) containing an active charge (2), and with an ignition device (4) that acts on a detonator (12) to ignite the active charge (2). In order to achieve this feature, after the hand grenade (1) has been thrown the ignition can be triggered without delay if the tactical situation requires it, and no danger arises for the shooter if the hand grenade (1) with the safety device released is dropped accidentally. The invention pertains to an electronic ignition system composed of an ignition trigger (6) and a fuze (8) used as the ignition device (4), whereby the ignition trigger (6) remains with the shooter when the hand grenade (1) is thrown and the hand grenade (1) can be ignited by wireless only when the shooter activates an ignition trigger element (11) of the ignition trigger (6).Type: GrantFiled: July 26, 2006Date of Patent: November 29, 2011Assignee: Rheinmetall Landsysteme GmbHInventors: Hermann Grosch, Michael Günther

Publication number: 20110283911Abstract: A system communicates data to a detonating fuse (3) of a projectile (P) of a firearm, and sends the data to a processing unit, inserted in the fuse. The projectile is of the under-calibre type with respect to the size of the barrel for which, in order to correctly insert the projectile in the same, an adaptor is used, formed by a capsule (2) fitting on the projectile, having an outer diameter which substantially corresponds to that of the barrel.Type: ApplicationFiled: May 12, 2011Publication date: November 24, 2011Applicant: OTO MELARA S.p.A.Inventor: Nicola Gianneschi

Publication number: 20110265677Abstract: A plurality of detonator assemblies in signal communication with a blasting machine, each detonator assembly consisting of a detonator, a storage compartment for storing programmed delay time and/or oscillation count and a countdown oscillator. A transmitter for transmitting a blast rehearsal stop start and stop signal, said signals being separated by said programmed delay time individually selected for each detonator signal. The oscillator counting the total oscillation count corresponding to said delay time. When a detonator assembly receives a FIRE command, the individual countdown oscillators countdowns the total oscillation count associated with its detonator assembly.Type: ApplicationFiled: May 29, 2009Publication date: November 3, 2011Applicant: Orica Explosives Technology PTY LTDInventors: Dirk Hummel, Michael John Mccann
