The patent describes a wireless detonator arrangement that includes an initiator, power supply, and multiple housings designed to connect and process wireless signals for detonating explosives. The system features a signal processing assembly that ignites the initiator in response to a fire command signal.

Claim 1

A wireless detonator arrangement ( 10 ) which includes an initiator ( 40 ), a first housing ( 12 ) in which is mounted a power supply ( 18 ), and contacts ( 46 ) connected to the power supply ( 18 ), a second housing ( 14 ) which contains an explosive material ( 20 ), contacts ( 52 ) at a first end ( 22 ) of the second housing ( 14 ), contacts ( 48 ) at a second end ( 24 ) of the second housing ( 14 ), and conductors ( 50 ) which extend from the contacts ( 48 ) to the contacts ( 52 ), and a third housing ( 16 ) which is engageable with the first end ( 22 ) of the second housing ( 14 ), a signal processing assembly ( 30 ) mounted inside the third housing ( 16 ), the signal processing assembly ( 30 ) including a receiver ( 32 ) and a processor ( 36 ) for processing wireless signals received by the receiver ( 32 ), and contacts ( 54 ) connected to the signal processing assembly ( 30 ), the first housing ( 12 ) being engageable with the second end ( 24 ) of the second housing ( 14 ) thereby to connect the power supply ( 18 ) to the signal processing assembly ( 30 ) via a conductive path comprising the contacts ( 46 , 48 ), the conductors ( 50 ) and the contacts ( 52 , 54 ), and wherein the signal processing assembly ( 30 ), responsive to a fire command signal, causes ignition of the initiator ( 40 ). an initiator ( 40 ), a first housing ( 12 ) in which is mounted a power supply ( 18 ), and contacts ( 46 ) connected to the power supply ( 18 ), a second housing ( 14 ) which contains an explosive material ( 20 ), contacts ( 52 ) at a first end ( 22 ) of the second housing ( 14 ), contacts ( 48 ) at a second end ( 24 ) of the second housing ( 14 ), and conductors ( 50 ) which extend from the contacts ( 48 ) to the contacts ( 52 ), and a third housing ( 16 ) which is engageable with the first end ( 22 ) of the second housing ( 14 ), a signal processing assembly ( 30 ) mounted inside the third housing ( 16 ), the signal processing assembly ( 30 ) including a receiver ( 32 ) and a processor ( 36 ) for processing wireless signals received by the receiver ( 32 ), and contacts ( 54 ) connected to the signal processing assembly ( 30 ), the first housing ( 12 ) being engageable with the second end ( 24 ) of the second housing ( 14 ) thereby to connect the power supply ( 18 ) to the signal processing assembly ( 30 ) via a conductive path comprising the contacts ( 46 , 48 ), the conductors ( 50 ) and the contacts ( 52 , 54 ), and wherein the signal processing assembly ( 30 ), responsive to a fire command signal, causes ignition of the initiator ( 40 ).
