Abstract: A system and method of repairing a pipe including securing a reinforcing material, such as a dry fiber structure (e.g., a carbon fibers) to the surface of the pipe. A polymeric material is placed on top of the reinforcing material, self-penetrating the dry fiber structure. The polymeric material substantially saturates the reinforcing material and cures to form a reinforced polymeric composite which may increase or restore the pressure rating or operating pressure capacity of the pipe. Optionally, an outer containment component, such as a sleeve, shell, box, wall, outer pipe, and so on, may be installed around the reinforcing material prior to introduction of the polymeric material. In this case, the polymeric material may be placed (i.e., poured) into the interior of the containment component on top of the reinforcing material.

Abstract: Ultrasound is used to provide input data for a blood pressure estimation scheme. The use of transcutaneous ultrasound provides arterial lumen area and pulse wave velocity information. In addition, ultrasound measurements are taken in such a way that all the data describes a single, uniform arterial segment. Therefore a computed area relates only to the arterial blood volume present. Also, the measured pulse wave velocity is directly related to the mechanical properties of the segment of elastic tube (artery) for which the blood volume is being measured. In a patient monitoring application, the operator of the ultrasound device is eliminated through the use of software that automatically locates the artery in the ultrasound data, e.g., using known edge detection techniques. Autonomous operation of the ultrasound system allows it to report blood pressure and blood flow traces to the clinical users without those users having to interpret an ultrasound image or operate an ultrasound imaging device.

Abstract: A vibration damping technique for a wind turbine system is described. The wind turbine system includes a vibration damper, which provides a variable signal to control torque produced by a generator of the wind turbine system.

Abstract: A connector arrangement for packaged electrical systems, such as motor control centers includes a component connector assembly mounted to component supports for providing network signals and control power to components on the support. A mating prewired connector assembly in the enclosure is forced to mate with the component connector assembly when the component support is fully engaged within the enclosure. Thereafter, the component support may be partially withdrawn from the enclosure to disconnect main power from the component support, while leaving network connections and control power connections by virtue of the mated connectors. The connectors engage by non-sliding contact both when fully engaged and when the components are partially withdrawn from the enclosure.

Abstract: In accordance with one exemplary embodiment the invention provides a multi-parameter fiber optic sensing system with an aperiodic sapphire fiber grating as sensing element for simultaneous temperature, strain, NOx, CO, O2 and H2 gas detection. The exemplary sensing system includes an aperiodic fiber grating with an alternative refractive index modulation for such multi-function sensing and determination. Fabrication of such quasiperiodic grating structures can be made with point-by-point UV laser inscribing, diamond saw micromachining, and phase mask-based coating and chemical etching methods. In the exemplary embodiment, simultaneous detections on multi-parameter can be distributed, but not limited, in gas/steam turbine exhaust, in combustion and compressor, and in coal fired boilers etc.

Abstract: The present technique addressably handles image data, which is decomposed and tessellated into a plurality of tessellated sub-band blocks. The tessellated sub-band blocks may be addressed by an array of indices, which identify specific data blocks of the image data by decomposition level and spatial coordinates of the tessellated sub-band blocks. Accordingly, a desired region of the image data at multiple resolutions can be identified and individually handled for storage, transmission, retrieval, and display. The desired region also can be reference marked based on the array of indices.

The use of these compounds in preparing bis(cyclopentadienyl)methanes and related compounds, and ansa-metallocenes, is disclosed.

Abstract: A reduced form factor component support is provided for motor control centers and similar packaged electrical systems. The reduced form factor component support may be used with smaller components, such as small motor starters, motor drives, and so forth. Electrical connections with standard bus bars in the enclosure are made through special connectors mounted on subplates in the rear of the enclosure, or by an invertible stab housing that can allow the reduced form factor component support to share conventional slots in a bus cover, thereby providing access to the supply power in the enclosure.

Abstract: The present technique provides for the use of spectroscopic probes, such as Raman probes, within the conduits of a polyolefin production system. The Raman probe or other spectroscopic probes may be used to obtain spectroscopic measurements of the contents of the conduits. The spectroscopic measurements may be processed and analyzed to determine the composition of the conduit contents. In addition, the spectroscopic measurements may be used in conjunction with correlations or other statistical models to determine one or more properties of interest of a constituent of the conduit contents. One or more processes upstream and/or downstream of the conduit may be adjusted in response to the determined composition or composition properties.
