  • Detonation control system
    Patent number: 8369062
    Abstract: According to certain embodiments, a detonation control system includes a controller circuit coupled to a manual switch and a detonation device. The detonation device is configured to activate an explosive. The controller circuit includes a memory operable to store one of a multiple time-to-fire settings representing a time delay from arming the detonation device to activation of the detonation device. The controller circuit is operable to store a first time-to-fire setting in the memory, store another of the multiple time-to-fire settings in the memory upon actuation of the manual switch, and repeat the step of storing another of the multiple time-to-fire settings in the memory for each actuation of the manual switch.

  • Remote Explosion Detonation System
    Publication number: 20110174181
    Abstract: According to one embodiment of the disclosure, a remote explosive detonation system includes a transmitter and at least one receiver having a detonator. The transmitter transmits an electro-magnetic signal having a transmitter identification code that may be received by the receiver. The receiver initiates the detonator if the transmitter identification code matches an internal identification code stored in the receiver.
