Abstract: Generally described, embodiments are directed to a temperature calibration system that includes a calibration unit, a closed fluidic system configured to remove heat from the calibration unit, and a cooling assembly configured to remove heat from the closed fluidic system. The closed fluidic system includes a fluid that has a critical point that is less than a temperature that would cause damage to the cooling assembly.

Abstract: A distributed control system architecture (HSE) provides an open, interoperable solution optimized for integration of distributed control systems and other control devices in a high performance backbone, provides an open, interoperable solution that provides system time synchronization suitable for distributed control applications operable over a high performance backbone, and provides an open, interoperable solution that provides a fault tolerant high performance backbone as well as fault tolerant devices that are connected to the backbone. The distributed control system architecture comprises a High speed Ethernet Field Device Access (HSE FDA) Agent, which maps services of a distributed control system, e.g., a fieldbus System, to and from a standard, commercial off-the-shelf (COTS) Ethernet/Internet component.

Abstract: A method of fault detection and recovery utilizes dual independent networks to provide fault-tolerance. These networks, a primary and alternate network, are utilized such that communications for a particular computer take place via that computer's preferred network by default. Faults are detected through the use of a heartbeat pinging mechanism to detect faults on the network itself and by periodic port integrity checks to detect port faults. The integrity of the non-default network and port are also periodically verified to assure effective fault recovery. Upon detection of a fault, a packet routing table in the detecting computer is altered to set the detecting computer's default network to the previously non-default network. Additionally, a new gateway packet is transmitted which allows other network computers to modify their routing tables to communicate with the detecting computer over its current default network.
