Abstract:

An apparatus for interconnection of two personal computer style processor printed circuit boards comprises a bridge printed circuit board having edge connectors on opposing edges thereof and support member for supporting the processor printed circuit boards in facing parallel arrangement with each edge connector of the bridge printed circuit board engaged in a mating socket on one of the processor boards. The support member advantageously provides pivotable support of at least one of the processor boards to permit insertion and removal of an edge connector of the bridge board into and from the mating socket of a processor board. The support member further advantageously comprises an enclosure and the pivotable support advantageously comprises a support bracket having notched end panels for engagement with pivot pins fixed to opposing surfaces of the enclosure.

Abstract:

A distributed control system may include a main processing unit, a distributed control module, and a controllable component. The distributed control module may be configured to determine a fault state associated with a control loop using a built-in test module. The built-in test module may be incorporated into the distributed control module. The fault state may include no faults, a communication fault, a sensor operation fault, or a controllable component fault. The distributed control module may be configured to transmit a closed-loop control command from the distributed control module to a controllable component when the fault state comprises no faults, or transmit an augmented control command from the distributed control module to the controllable component when the fault state comprises a communication fault or a sensor operation fault, or transmit a disconnect control command from the distributed control module to the controllable component when the fault state comprises a controllable component fault.
