Malfunctioning medical devices are one of the leading causes of serious injury and death in the US. Between 2006 and 2011, 5,294 recalls and approximately 1.2 million adverse events were reported to the US Food and Drug Administration (FDA). Almost 23 percent of these recalls were due to computer-related failures, of which approximately 94 percent presented(More)
Networks on Chips (NoCs) provide a mechanism for handling complex communications in the next generation of integrated circuits. At the same time, lower yield in nano-technology, makes self repair communication channels a necessity in design of digital systems. This paper proposes a reliable NoC architecture based on specific application mapped onto an NoC.(More)
This paper presents a fault-tolerant hardware architecture for robust wearable heart rate monitoring. The proposed architecture is designed for fusion of the heart rates estimated from both electrocardiogram (ECG) and arterial blood pressure (ABP) signals, with small hardware footprint and low energy consumption. It benefits from the following unique(More)
This paper discusses the configuration of a fault-tolerant mesh-based NoC architecture. In this architecture , spare links provide a mechanism for rerouting data packets in presence of NoC faults. Two algorithms, Exhaustive and Greedy, are used to find the best configuration. The NoC is modeled at the high transaction level using SystemC TLM. This enables(More)
BACKGROUND Use of robotic systems for minimally invasive surgery has rapidly increased during the last decade. Understanding the causes of adverse events and their impact on patients in robot-assisted surgery will help improve systems and operational practices to avoid incidents in the future. METHODS By developing an automated natural language processing(More)
Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

This paper presents design, implementation and evaluation of an efficient embedded hardware for accurate automated detection of epileptic seizures. Three hardware configurations are proposed and evaluated in terms of accuracy of detection, utilization of hardware resources, and power consumption. The results show that a solution based on combination of the(More)
A robust medical monitoring device should be able to provide intelligent diagnosis based on accurate analysis of physiological parameters in real-time. At the same time, such device must be able to adapt to the characteristics of a specific patient and desired diagnostic needs, and continue to operate even in presence of unexpected artifacts and accidental(More)
Evolution of Electronic System Level design meth-odologies, allows a wider use of Transaction-Level Modeling (TLM). TLM is a high-level approach to modeling digital systems that emphasizes on separating communications among modules from the details of functional units. This paper explores different functional testing approaches for the implementation of(More)
