They want more or better diagnostics, less downtime, and reduced installation and maintenance costs. At the same time, they are demanding improved throughput. With increased functionality comes increased traffic (data) on the control system network. Today's automation networks, most of which are source/destination based, cannot offer the required functionality and accommodate the increased traffic flow, thus restricting system capabilities and productivity improvements. Increased demands on automation networks have forced the evolution of a new network model-one that provides greater functionality, makes more efficient use of network bandwidth, and increases information flow, all while reducing traffic on the wire. Unfortunately, much of the discussion to date about networks has focused on baud rates, protocol efficiency, and physical characteristics (i.e. type of wire used). In reality, it's more complex than that. Available diagnostics, messaging types and throughput must all be considered when evaluating a control system network. The most important factor affecting these capabilities in the control environment is the network model. The source/destination model used for the past two decades can no longer meet today's network needs. The only model available today that can meet these demanding requirements and allows for future migration is the producer/consumer network model. This model is outlined.","PeriodicalId":361384,"journal":{"name":"1998 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

The inspection system, which offers a scalable, open architecture, can be manufactured at relatively low cost using off-the-shelf components. While synchronized to the motion of the loom, the developed system first acquires very high-quality, vibration-free images of the fabric using either front or backlighting. Then the acquired images are subjected to a novel defect segmentation algorithm, which is based on the concepts of wavelet transform, image fusion and the correlation dimension. The essence of this segmentation algorithm is the localization of those events (i.e., defects) in the input images that disrupt the global homogeneity of the background texture. The efficacy of this algorithm, as well as the overall inspection system, has been tested thoroughly under realistic conditions. The system was used to acquire and to analyze more than 3700 images of fabrics that were constructed with two different types of yarn. In each case, the performance of the system was evaluated as an operator introduced defects from 26 categories into the weaving process. The overall detection rate of the presented approach was found to be 89% with a localization accuracy of 0.2 in. (i.e., the minimum defect size) and a false alarm rate of 2.5%.","PeriodicalId":361384,"journal":{"name":"1998 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.

The underlying cause of these phenomena is that nonlinear electrical loads are being used more frequently in the control room and plant environment. The uninterruptible power supply (UPS) has been the mainstay of power solutions for conditioning and backup in the industrial environment. The traditional UPS design for high-performance, high-reliability applications has been the application of the double conversion topology, in single-phase output configuration, using passive output harmonic filters to mitigate the ill-effects of nonlinear loads on traditional UPS systems. Unfortunately, passive output harmonic filters are expensive, require additional foot-print and cannot adapt themselves to changing load environment. In the context of modern process control plants and current economic conditions, passive filters are ineffective in delivering the lowest cost, smallest footprint solution. This paper describes the latest advances in the design of single-phase UPS systems incorporating real-time, dynamic digital feedback control to accommodate nonlinear loads.","PeriodicalId":361384,"journal":{"name":"1998 IEEE Annual Textile, Fiber and Film Industry Technical Conference (Cat.
