Abstract: A fire extinguisher system. The system includes a first fire extinguisher containing a first agent that is suitable for extinguishing fire, the first fire extinguisher having a first discharge port for discharging the first agent therethrough, and a first actuator for actuating the first discharge port. The system also includes a second, similar fire extinguisher. The system also includes a valve coupled to the first discharge port via a first line and coupled to the second discharge port via a second line, wherein the valve is configured to release the first agent and the second agent into a third line. The system also includes a controller connected to the first actuator and the second actuator, the controller configured to activate the first actuator and the second actuator in a predetermined sequence.

Abstract: A system, apparatus, and method for testing a squib circuit. An electrical signature of the squib circuit is monitored when a test switch in the squib circuit is activated. The electrical signature of the squib circuit is based on characterizing resistors electrically connected to squibs in the squib circuit in which each characterizing resistor in the characterizing resistors has a resistance value. A health of each squib in the squib circuit is determined based on the electrical signature of the squib circuit.

Abstract: A monolithic three-dimensional fluidic check device is presented. The monolithic three-dimensional fluidic check device comprises a housing surrounding a fluidic flow path and having a first opening at a first end of the housing and a second opening at a second end of the housing, and an elongated center body positioned within and extending along the fluidic flow path. The elongated center body is stationary relative to a flow of fluid.
