Today’s FPGAs (Field Programmable Gate Arrays) are widely used, but not to their full potential. In Virtex series FPGAs from Xilinx a special feature, the dynamic and partial reconfiguration is available. This feature enables a designer to create a system on chip with a static area and a reconfigurable part that can be exchanged during run-time while the remaining static portion is still operat...

Inexpensive Multi-Touch Pressure Acquisition Devices (IMPAD) are flexible, paperthin sensing surfaces that can scale from portable devices to large tables. These devices can sense varying levels of pressure at a resolution high enough to sense and distinguish multiple fingertips, the tip of a pen or pencil and other objects. Other potential applications include writing pads, floor mats and entr...

Constraint-based scheduling has become the dominant form of modeling and solving scheduling problems. Recently, due to ever more powerful embedded processors, it has become possible to embed and run constraint-based schedulers on-line even for fast processes such as product assembly sequencing. This makes constraint-based scheduling interesting to the control community as a new tool for system ...

This paper proposes an approach to achieving fast reconfiguration of modular manufacturing systems, based on an ontology-based reconfiguration agent. The agent uses ontological knowledge of the manufacturing environment for the purpose of reconfiguration without human intervention. The current mass customization era requires increased flexibility and agility in the manufacturing systems to adap...

With the widespread deployment of IP over WDM networks, it becomes necessary to develop dynamic lightpath and topology reconfiguration mechanisms and reconfiguration triggers that can effectively exploit WDM reconfigurability. A reconfiguration model for overlay IP/WDM networks is introduced. An IP over WDM network testbed has been set up using Telcordia MONET WADMs and IP routers. The testbed ...

This paper proposes a review on Partial reconfiguration using Field Programmable Gate Array (FPGA). By downloading configuration bit files Partial Dynamic Reconfiguration (PDR) dynamically modifies the hardware portion of the device. Both FPGA and reconfigurable are used to speed up the performance of various applications. This makes the FPGA to be used in new dimension with an advantage of mor...

Using analog wireless communication, we demonstrate a master–slave load-sharing control of a parallel dc–dc buck converter system, thereby eliminating the need for physical connection to distribute the control signal among the converter modules. The current reference for the slave modules is provided by the master module using radio-frequency (RF) transmission, thereby ensuring even sharing of ...

Future spaceflight missions will require the use of distributed satellite systems, where multiple spacecraft must work in concert to manipulate, assemble, service, or function as a cohesive unit. Such spacecraft architectures must be able to capitalize on the resources of the system as a whole. Resource Aggregated Reconfigurable Control (RARC) techniques will enable satellites to control flexib...

Modern technological processes include complex and large scale systems, where faults in a single component have major effects on the availability and performances of the system as a whole. For example manufacturing systems consists of many different machines, robots and transportation tools all of which have to correctly satisfy their purpose in order to ensure and fulfil global objectives. In ...

In this paper, a novel fault-tolerant control scheme is proposed for a class of uncertain multiple-input-multiple-output (MIMO) nonlinear systems based on online fuzzy clustering and identification. The unknown nonlinear function of the system is identified online using an evolving Takagi-Sugeno (T-S) fuzzy model and the fault-tolerant control law is designed based on the identified fuzzy model...
