The stress and poor sleep quality of a person may be used as two of several components for predicting the onset of mental health problems, in particular depression. Ergonomie smart sensors that can determine the heart rate variations related to stress and the variability of sleep may provide unique insights to the coping behavior of stressed people. Rather(More)
A new paradigm to design computer systems called evolving reconfigurable architecture (ERA) is proposed. Several holistic principles are introduced and pursued through the ERA design cycle. We show how reconfigurability is implemented at the level of hardware elements and system software structure. Two new models: (i) graph-logic and (ii)(More)
Electroencephalogram (EEG) signal plays an important role in E-healthcare system, especially the mental healthcare field. In order to improve access and quality of EEG data delivery, detect the mental depression and reduce the hardware cost, we present the design and application of a novel wearable EEG system. After the introduction of hardware, a novel(More)
This paper describes the design and implementation of a small real time operating system (OS) called Minos and its application in an onboard active safety project for general aviation. The focus of the operating system is predictability, stability, safety and simplicity. We introduce fault tolerance aspects in software by the concept of a very fast reboot(More)
