Abstract

A networked electronic ordnance system and method for controlling a variety of pyrotechnic devices at different energy levels include a bus controller controlling at least one pyrotechnic device operating at a first energy level and a smart connector adapting at least one pyrotechnic device operating at a second energy level to control by the bus controller. The smart connector may also include a plurality of capacitors for firing the pyrotechnic device(s). In an embodiment, at least one pyrotechnic device operating at a first energy level and at least one pyrotechnic device operating at a second level include a logic device have a unique identifier. The smart connector may also include an energy reserve capacitor and an emitter follower circuit electrically connected to a logic device. Additionally, the smart connector may be connected to an initiator for firing at least one pyrotechnic device at the second energy level.

Claims

1. A networked electronic ordnance system for controlling a variety of pyrotechnic devices at different energy levels, said system comprising:

a plurality of pyrotechnic devices connected by a network, said plurality of pyrotechnic devices comprising at least one pyrotechnic device operating at a first energy level and at least one pyrotechnic device operating at a second energy level, said second energy level being higher than said first energy level;

a bus controller connected to said plurality of pyrotechnic devices through said network, said bus controller being operative to transmit commands onto the network at the first energy level; and

a smart connector interconnecting at least one pyrotechnic device operating at said second energy level to the network for control by said bus controller, said smart connector being responsive to control commands issued by said bus controller at said first energy level to store an activation energy at said second energy level and transmit said activation energy to said interconnected pyrotechnic device.

2. The system of claim 1, wherein said smart connector further comprises a plurality of capacitors for firing said at least one pyrotechnic device at said second energy level.

4. The system of claim 1, wherein said smart connector further comprises an energy reserve capacitor and an emitter follower circuit electrically connected to a logic device.

6. The system of claim 1, wherein said smart connector further comprises electrostatic discharge protection.

7. The system of claim 1, further comprising a plurality of said smart connectors.

21. The system of claim 1, wherein said smart connector adapts a firing instruction from said bus controller for said at least one pyrotechnic device.

22. The system of claim 1, wherein said smart connector receives a disarming command and dissipates activation energy at said at least one pyrotechnic device in response to said disarming command.

23. The system of claim 1, wherein said smart connector includes a logic device for interpreting data received from said bus controller to operate at least one pyrotechnic device operating a said first energy level and at least one pyrotechnic device operating at said second energy level.

24. The system of claim 1, wherein said bus controller generates a command for firing a pyrotechnic device at a low energy level and said smart controller translates said command into a command for firing a pyrotechnic device at a high energy level.
