Patent ID: 7644661

Claim:
A networked electronic ordnance system, comprising: a bus controller connected to a network for (1) transmitting onto the network a digital arming command using at least one unique identifier, (2) altering an analog condition of the network to correspond to a firing command, and (3) transmitting onto the network a digital firing command using at least one unique identifier, the digital arming command causes activation energy to change one or more of a plurality of pyrotechnic devices connected be the network to the bus controller; and at least one of the plurality of the pyrotechnic devices including: a bus interface for sensing the analog condition of the network, a capacitor for storing the activation energy, an initiator, and a logic device having a unique identifier that stores activation energy in the capacitor upon receiving the digital arming command that includes the unique identifier of its logic device, and, once armed, releases the stored activation energy from the capacitor into the initiator upon (1) detecting that the digital firing command is received that includes its unique identifier, and (2) determining that the bus interface senses that the analog condition of the network corresponds to the received firing command.
