Patent ID: 7568429

Claim:
A wireless detonator assembly for use in connection with a blasting machine that transmits at least one wireless command signal to the wireless detonator assembly, the wireless detonator assembly comprising: a detonator comprising a base charge; command signal receiving and processing means for receiving and processing said at least one wireless command signal from said blasting machine; a charge storage device for storing electrical energy; at least one power source to power said command signal receiving and processing means, and to charge said charge storage device, each of said at least one power source supplying a maximum voltage or current that is less than a threshold voltage or current to actuate said base charge; and a firing circuit in electrical connection with said charge storage device; whereupon receipt by said command signal receiving and processing means of a command signal to FIRE causes said electrical energy stored in said charge storage device to discharge into said firing circuit, said base charge actuating if a voltage or current in said firing circuit resulting from discharge of said electrical energy from said charge storage device exceeds said threshold voltage or current, wherein the wireless command signal comprise radio waves.
