Filed:

Nov 22, 2004

Appl. No.:

10/994754

Inventors:

Martin R. Davis - Champlin MN, US
Carl Nelson - Minnetonka MN, US
Mark J. Tomes - Plymouth MN, US

Assignee:

Alliant Techsystems Inc. - Edina MN

International Classification:

F42C 19/06

US Classification:

102216, 102215

Abstract:

A detonation timing apparatus and method of determining a detonation time is disclosed. The detonation timing apparatus comprises an initiation sensor, at least one impact sensor, and at least one controller. The at least one controller may be configured for sensing an initiation event associated with the initiation sensor and sensing an impact event associated with the at least one impact sensor. The at least one controller is further configured for determining an impact velocity estimate proportional to a temporal difference between the initiation event and the impact event, using the impact velocity estimate to determine the detonation delay, and generating the detonation event at the detonation delay after the impact event. The timing apparatus and method of determining a detonation time may be incorporated in a fuze, which may be incorporated in an explosive projectile.

Abstract:

A conductive adhesive composition is provided and articles that include the adhesive composition as a component thereof. The conductive adhesive composition comprises: (a) pressure sensitive adhesive; (b) electrolyte comprising water soluble or water dispersible organic chloride; and (c) humectant. In some embodiments, the conductive adhesive composition is a bicontinuous composition comprising an aqueous phase and an oil phase, and the bicontinuous composition may be derived from a polymerizable microemulsion composition, the microemulsion composition comprising: an aqueous phase comprising one or more hydrophilic monomers or oligomers and/or one or more amphiphilic monomers or oligomers in water, the water-soluble or water-dispersible organic chloride, surfactant and humectant; and an oil phase comprising one or more hydrophobic monomers or oligomers. Biomedical articles such as biomedical electrodes, may incorporate the foregoing adhesive as a component.
