Epilepsy is one of the most common neurological disorders that greatly impair patients' daily lives. Traditional epileptic diagnosis relies on tedious visual screening by neurologists from lengthy EEG recording that requires the presence of seizure (ictal) activities. Nowadays, there are many systems helping the neurologists to quickly find interesting(More)
Over 50 million people worldwide suffer from epilepsy. Traditional diagnosis of epilepsy relies on tedious visual screening by highly trained clinicians from lengthy EEG recording that contains the presence of seizure (ictal) activities. Nowadays, there are many automatic systems that can recognize seizure-related EEG signals to help the diagnosis. However,(More)
In this paper, two Doppler radars are used to monitor the pulse movements at the heart and the calf in order to measure the pulse wave velocity (PWV) wirelessly. Both simulation and experiment have been performed to demonstrate the feasibility of the proposed noncontact PWV monitoring. A three-stage calibration procedure, including DC offset calibration,(More)
We report the realization and properties of a high-resolution solid-state self-emissive microdisplay based on III-nitride semiconductor micro-size light emitting diodes (lLEDs) capable of delivering video graphics images. The luminance level of III-nitride microdisplays is several orders of magnitude higher than those of liquid crystal and organic-LED(More)
Micro-size light emitting diode (µLED) arrays based on III-nitride semiconductors have emerged as a promising technology for a wide range of applications. If InGaN µLED arrays can be integrated on to Si complementary metal–oxide–semiconductor (CMOS) substrates for active driving, these devices could play crucial roles in ultra-portable products such as next(More)
Full-scale self-emissive displays based on gallium nitride micro-size LEDs may be suitable for ultra-portable products such as next-generation handheld projectors. Microdisplays, which find use in head-wearing displays, cam-corders, and viewfinders, are small high-resolution displays that are typically magnified by optics to enlarge the image that the user(More)
Continuous and accurate monitoring of human vital signs is an important part of the healthcare industry, as it is the basic means by which the clinicians can determine the instantaneous status of their patients. Doppler-based noncontact vital signs (NCVS) sensor systems can monitor the heart and respiration rates without touching the patient, but it has(More)
Epilepsy is the third most common neurological illness, affecting 1% of the world's population. Despite advances in medicine, about 25 to 30% of the patients do not respond to or cannot tolerate the severe side effects of medical treatment, and surgery is not an option for the majority of patients with epilepsy. The objective of this article is to review(More)
—Epilepsy is one of the most common neurological disorders that greatly impair patients' daily lives. A classifier for automated epileptic EEG detection and patient monitoring can be very important for epilepsy diagnosis and patients' quality of life, especially for rural areas and developing countries where medical resources are limited.
