Magneto-inductive on-command fuze and firing device
First Claim
1. A fuze for ordnance responsive to magneto-inductive command signals in the ELF to VLF range from a remote station to change its status and to transmit magneto-inductive status signals in the ELF to VLF range to said remote station confirming said status, said command and status signals being transmitted in said ELF to VLF range to assure transmission reliably through ground, water, and air, said fuze having a receiver portion coupled to an antenna to receive said magneto-inductive command signals and a transmitter portion coupled to said antenna to transmit said magneto-inductive status signals and said receiver portion having high gain narrow band filter amplifiers receiving said magneto-inductive command signals, a demodulator-tone detector module coupled to said high gain narrow band filter amplifiers, output drivers coupled to said demodulator-tone detector module, and a safety, arming, and confirmation section.

Abstract
A fuze is enabled, armed, and fired while indicating its status to remote command/receiver stations so that interconnected line charges and other ordnance items can be detonated with increased safety and reliability from a safe man-weapon separation distance. The fuze is responsive to remotely transmitted magneto-inductive command signals in the extremely low frequency (ELF) to very low frequency (VLF) range to change its status and to transmit magneto-inductive status signals in the ELF to VLF range confirming its status to at least one of the remote stations. Transmission and reception of magneto-inductive signals in the ELF to VLF range allow for a unique communication method that provides safe and reliable communication suitable to effect fuzing of explosive devices on the beach through seawater, air, earth, buildings, vegetation and sediment or any combination of these conditions.

5. A fuze system for ordnance comprising:
-
a transmitter-receiver at a remote station to transmit magneto-inductive command signals in the ELF to VLF range and a fuze coupled to ordnance, said fuze being responsive to said magneto-inductive command signals in the ELF to VLF range to change its status and to transmit magneto-inductive status signals in the ELF to VLF range to said transmitter-receiver at said remote station to confirm said status, said command and status signals being transmitted in said ELF to VLF range to assure transmission reliably through ground, water, and air said transmitter-receiver having a transmitter section coupled to a first antenna to transmit said magneto-inductive command signals and a receiver section coupled to said first antenna to receive said magneto-inductive status signals, and said fuze having a receiver portion coupled to a second antenna to receive said magneto-inductive command signals and a transmitter portion coupled to said second antenna to transmit said magneto-inductive status signals. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A fuze system for ordnance comprising:
-
means for transmitting magneto-inductive command signals in the ELF to VLF range from a remote station;
means coupled to ordnance for changing its status in response to said magneto-inductive command signals in the ELF to VLF range and for transmitting magneto-inductive status signals in the ELF to VLF range to said transmitting means at said remote location to confirm said status, said command and status signals being transmitted in said ELF to VLF range to assure transmission reliably through ground, water, and air;
a first antenna coupled to said transmitting means; and
a second antenna coupled to said changing and transmitting means. - View Dependent Claims (15)
