Abstract: The present invention generally relates to network-attack-resilient intrusion-tolerant Supervisory Control and Data Acquisition (SCADA) systems. Some implementations utilize redundant, proactively-recovery-configured servers at multiple centers communally executing a replication protocol. Some implementations, in addition to control centers, include data centers, which participate in the replication protocol, except that they may not be capable of controlling remote units such as Remote Terminal Units (RTUs).

Abstract: Systems, computer readable media, and method concern assigning an abstraction representation to data associated with a system of the SCADA environment. The method also includes providing the abstraction representation to a control system associated with the system of the SCADA environment. The control system is implemented in a computer system. Further, the method includes receiving actual data from the system of the SCADA environment. Additionally, the method includes generating abstract data from the actual data using the abstraction representation. The method, also includes forwarding the abstract data to the control system.

Abstract: Woven fabrics made from non-stretch yarns yet having high levels of stretch and recovery are described. The fabrics include at least about 50% of a synthetic fiber component, and are woven such that the warp and filling are approximately balanced by weight before warp contraction, with about 50% warp density or less. The fabrics are exposed to a cumulative dynamic tension in the warp direction of at least about 250 min-lb/linear ft, and are then finished to about 70-80% of their reed width at a temperature greater than or equal to the heat set temperature for the synthetic fiber component. The fabrics may also be exposed to a face finishing process and/or a fluid treatment process.
