Abstract: A remote firing system for remotely detonating explosive charges includes features that provide safety and efficiency improvements. These features include safety communication among multiple remote devices and multiple controller devices, a polling functionality permitting rapid deployment of system devices, electronic key systems, programmable remote devices for easy replacement of failing remote devices, and an event history log for the remote devices for efficient diagnostic evaluation.

Abstract: A protective device for a field apparatus includes first and second lateral plates, each plate having a top end and a bottom end. The first and second lateral plates are opposingly situated to mutually support each other in an A-shaped structure. In this A-shaped structure, the top ends are coupled together by at least one coupling device substantially at the apex of the “A”, and the bottom ends are coupled together by a fastening assembly. The bottom fastening assembly acts to restrain the rending of the A-shaped structure by a force generated from debris striking the first or second lateral plate. Each lateral plate also has a handle positioned in proximity to the top end. When a user grabs both handles, the A-shaped structure collapses for storage. The protective device further includes a transmission line and a device for transmitting and receiving radio waves to an electromagnetic field apparatus.
