Abstract: Automation security in a networked-based industrial controller environment is implemented. Various components, systems and methodologies are provided to facilitate varying levels of automation security in accordance with security analysis tools, security validation tools and/or security learning systems. The security analysis tool receives abstract factory models or descriptions for input and generates an output that can include security guidelines, components, topologies, procedures, rules, policies, and the like for deployment in an automation security network. The validation tools are operative in the automation security network, wherein the tools perform security checking and/or auditing functions, for example, to determine if security components are in place and/or in suitable working order.

Abstract: A live loaded ball pipe joint design accommodates for seal decay without the need for maintenance or adjustment. The pipe ball joint includes a casing having a socket section with a substantially spherical interior surface. A ball pipe section is received in the socket section. A seal is received in an annular groove within the socket section and is disposed against the ball segment. A push ring is disposed against the seal and a spring is disposed against the push ring. A retainer is secured to the casing and is disposed against the spring for loading the spring against the push ring. The loaded spring accommodates for decay of the sealing components and automatically adjusts the position of the push ring as the sealing components decay.

Abstract: A closure assembly for terminating an end of a pipe (4) has an end-cap (4) holding and having fluid-tight connection to a mutually coaxial cylindrical plug (2) and circular collar (3). The plug (2) and the collar (3) are configurable between respective engaged and disengaged configurations and mutually spaced to provide an annular space therebetween when the plug (2) and collar (3) are in their disengaged configurations. The annular space is arranged to receive an end of a pipe (1) arranged coaxially with the plug (2) and collar (3), the plug (2) and collar (3) being respectively slidable into and over the end of the pipe (1). The plug (2), when in its engaged configuration, grips the inner face of said pipe (41) and to provide a fluid tight seal and the collar (3), when in its engaged configuration, grips the outer face of the pipe (1) and to provide a fluid tight seal.

Abstract: A boring apparatus, such as a drilling apparatus for forming holes in pressurized pipes, comprises a cutting head (5) mounted to a distal end of a boring bar (2) which is itself connected to a feed screw (3) by a feed nut so that relative rotation between the boring bar (2) and the feed screw (3) cause the cutting head (5) and boring bar (2) to traverse axially along the feed screw (3) while the cutting head (5) is rotated for cutting. The apparatus has a main drive motor arranged to drive the cutting head (5), boring bar (2) and a main drive shaft (4). The main drive shaft (4) and the feed screw (3) are operably connected at the proximal end through a pair of adjacent coaxial planetary gear assemblie (6) whose planetary gear carriers are liked to rotate in unison about the axis.

Abstract: Stimulation signals (22) are applied to a first circuit model (20) and the power behaviour of the circuit being modelled is determined from the behaviour of the first circuit model (20). In parallel, the same stimulation signals (22) are applied to a second circuit model (26) and the state variable changes within that second circuit model are calculated. The calculated power behaviour and the calculated state variable changes are then applied as training data inputs to a self learning power model, such as a neural network (28), which learns the relationship between state variable changes between the second model (26) and power behaviour of the circuit being simulated. In this way, a detailed first circuit model (20) may be used to calculate power behaviour and to train a separate power model (28, 30) which once trained can be publicly released without having to release sensitive information within the first circuit model (20).

Abstract: A first model (10), such as a architectural level model or an instruction set simulator model makes calls to a second model (12), such as a pipeline simulator for a data processing device returning cycle count or energy consumption values. The calls to the second model are relatively slow. The system stalls the returned behavioural characteristics from the second model (12) in a memo table (14) and when a sufficient number of these have been returned with sufficiently little variation between them, then they are marked as being valid for use in place of a call to the second model (12), thus speeding up modelling.

Abstract: A substrate is etched in a vacuum enclosure in a process which generates plasma light emission. The process is monitored by passing emitted light via a window, a thin film narrow band filter and a “Fabry-Perot” etalon to a detector. The output signal from the detector is analyzed by shape recognition techniques to derive a measure of the progress of the process. The shape recognition preferably makes use of digital filtering and comparison with reference data derived from the theoretical analysis or from a calibration run.

Abstract: A channel estimation method for a digital telecommunication station is disclosed. A frequency correction burst is sought by scanning of the wanted channel. The frequency correction burst is used to provide coarse time and frequency synchronizations. A synchronization burst is received. Calculating the cross-correlation of the expected training sequence with the training sequence contained in said synchronous burst to obtain a channel estimate. A frequency error estimate is derived from the channel estimate, and the frequency error of the received burst is corrected in accordance with said frequency error estimate. The received synchronous burst is equalized. The frequency corrected symbols are used to refine the time and frequency synchronizations.
