Automatic determination of correct IP address for network-connected devices

Abstract: The present invention is for automatic reconfiguration of industrial networked devices. More particularly, the system described herein facilitates use of TCP/IP networks, such as Ethernet, as an alternative for industrial fieldbus or device buses by removing the need to perform significant reconfiguration of devices such as I/O modules, sensors, or transducers under field replacement situations. The present invention uses a monitor agent to track the IP and MAC addresses of networked devices as well as port information. If a device fails, maintenance personnel make an in-field replacement of the failed device and the monitor agent automatically reassigns the IP address to the replacement device.

Low overhead fault-tolerant FPGA systems

Abstract: Fault-tolerance is an important system metric for many operating environments, from automotive to space exploration The conventional technique for improving system reliability is through component replication, which usually comes at significant cost: increased design time, testing, power consumption, volume, and weight We have developed a new fault-tolerance approach that capitalizes on the unique reconfiguration capabilities of field programmable gate arrays (FPGA's) The physical design is partitioned into a set of tiles In response to a component failure, a functionally equivalent tile that does not rely on the faulty component replaces the affected tile Unlike application specific integrated circuit (ASIC) and microprocessor design methods, which result in fixed structures, this technique allows a single physical component to provide redundant backup for several types of components Experimental results conducted on a subset of the MCNC benchmarks demonstrate a high level of reliability with low timing and hardware overhead

Reconfigurable architectures for VLSI processing arrays

Abstract: The paper presents the problem of fault tolerance in VLSI array structures: its aim is to discuss architectures capable of surviving a number of random faults while keeping costs (in terms of added silicon area and of increased processing time) as low as possible Two different approaches are presented, both based upon introduction of simple patterns of faults and by global reconfiguration techniques (rather than one-to-one substitution of faulty elements by spare ones) Various solutions are compared, and relative performances are discussed in order to determine criteria for selecting the one most suitable to particular applications

Accommodation of failures in the F-16 aircraft using adaptive control

Abstract: Surface and hardware failure affect the flight control system of the F-16 fighter aircraft. In the absence of failures and unpredictable changes, the controller, based on gain scheduling, performs very well and exhibits a good degree of robustness, even for high angles of attack. In order to accommodate for possible failure and maintain good performance characteristics, the control system is augmented with a hybrid adaptive linear quadratic control scheme. The augmented adaptive flight control system has the online capability for learning and accommodating to drastic changes in the aircraft dynamics due to surface or hardware failure. The proposed flight control system has been tested on the nonlinear model of the F-16 aircraft, and the simulation results demonstrate its ability to accommodate control failures and maintain good performance. >

Distribution network reconfiguration for energy loss reduction

Abstract: A new method for energy loss reduction in distribution networks is presented It is based on known techniques and algorithms for radial network analysis-oriented element ordering, power summation method for power flow, statistical representation of load variations and a recently developed energy summation method for the computation of energy losses These methods, combined with the heuristic rules developed to lead the iterative process, make the energy loss minimization method effective, robust and fast It presents an alternative to the power minimization methods for operation and planning purposes
