Filed:

Dec 10, 2003

Appl. No.:

10/733499

Inventors:

Eugene Pikus - Ham Lake MN, US
David Nohre - Monticello MN, US

International Classification:

F42C017/00

US Classification:

089006000

Abstract:

Fuze setting data for setting a projectile fuze may be transferred from a fuze setter to a fuze over a radiative data link. The radiative data link may comprise a signal transmission over one or more bands selected from a group consisting of the audio, ultrasonic, infrared, RF, visible and UV bands of the electromagnetic spectrum. In one embodiment, frequency shift keying is used to modulate a radio frequency carrier signal. Operational power for the fuze may be inductively transferred from the fuze setter to the fuze over a magnetic inductive link.

Abstract:

Microcontroller apparatuses and methods of use are disclosed. An explosive projectile system contains a faze and a remote fuze setter. The fuze includes a microcontroller comprising an RC-based clock generator and is configured to sample an accurate timing event sent from a crystal-based or similarly accurate timing device. The microcontroller is then calibrated with the received timing event and results are employed in a manner appropriate for desired implementation. Implementations of the microcontroller may include sampling a detonation delay value, in the form of a time pulse, and calibrating the microcontroller to issue a fire command at delay time after an impact event. Additionally, in a setter calibration application, a microcontroller may receive a carrier signal, calibrate the faze to an accurate time base and then set frequency boundary limits for subsequent data bit transfers.
