Inside a modern flat-panel display, the TFT array acts as the analog memory that stores the image information. To ensure high overall yield, it is crucial to thoroughly test the TFT array before it enters the assembly line. However, TFT array testing gets complicated in systemon-panel displays because the peripheral circuits integrated on the same substrate as the array limit the access to the ...

Three-phase induction motor drive requires high accuracy in high performance processes in industrial applications. Field oriented control, which is one of the most employed control schemes for induction motors, bases its function on the electrical parameter estimation coming from the motor. These parameters make an electrical machine driver work improperly, since these electrical parameter valu...

Writing code to interact with external devices is inherently difficult, and the added demands of writing device drivers in C for kernel mode compounds the problem. This environment is complex and brittle, leading to increased development costs and, in many cases, unreliable code. Previous solutions to this problem ignore the cost of migrating drivers to a better programming environment and requ...

The Federal Highway Administration’s (FHWA) High-Fidelity Simulator, called HYSIM, was recently upgraded to better meet the needs of FHWA’s Human Centered Systems research program. The HYSIM is a fully interactive driving simulator used for human factors research in highway safety and highway operations. It provides a platform to study driver performance in a broad spectrum of driving situation...

Legislators, journalists, and researchers alike have recently directed a great deal of attention to the effects of cellular telephone (‘cell phone’) use on driver behavior and performance. This paper demonstrates how cognitive modeling can aid in understanding these effects by predicting the impact of cell-phone dialing in a naturalistic driving task. We developed models of four methods of cell...

78 1094-7167/01/$10.00 © 2001 IEEE IEEE INTELLIGENT SYSTEMS avoidance technologies, enhance the driver’s ability to sense the surrounding environment. Driver assistance and automation technologies simulate the driver’s sensorimotor system to operate a vehicle either temporarily during emergencies or for prolonged periods. Such new information and control technologies that make vehicles smarter ...

Simulation is often used to gain an understanding of vehicle directional response. Furthermore, it is widely agreed that, given an adequate set of parameters that model the vehicle and the surface it drives on, it is reasonable to simulate a particular vehicle with a view toward understanding and perhaps improving its performance. This is not the case with the vehicle/driver system. Rather, in ...

SLAC National Accelerator Laboratory is developing a next generation H-bridge switch plate [1], a critical component of the SNS High Voltage Converter Modulator [2]. As part of that effort, a new IGBT gate driver has been developed. The drivers are an integral part of the switch plate, which are essential to ensuring fault-tolerant, high-performance operation of the modulator. The redesigned dr...
