Driving fatigue is more likely to bring serious safety trouble to traffic. Therefore, accurately and rapidly detecting driving fatigue state and alleviating fatigue are particularly important. In the present work, the electrical stimulation method stimulating the Láogóng point (PC8) of human body is proposed, which is used to alleviate the mental fatigue of drivers. The wavelet packet decomposi...
In order to give a warning to the drowsy driver, this paper proposes a new Fatigue Driving Detection Algorithm. AdaBoost algorithm is applied to fast detect and track human faces, and the algorithm is implemented in FPGA; differential template-based multi-algorithms are used to localize human eyes and recognize eye states; PERCLOS algorithm is adopted to analyze and determine whether a person i...
KEY POINTS Muscle fatigue can be defined as the transient decrease in maximal force that occurs in response to muscle use. Fatigue develops because of a complex set of changes within the neuromuscular system that are difficult to evaluate simultaneously in humans. The skeletal muscle of older adults fatigues less than that of young adults during static contractions. The potential sources of thi...
The effects of changes in arterial perfusion across the physiological range on the fatigue of a working human hand muscle were studied in seven normal subjects. With the hand above heart level, subjects made repeated isometric contractions of the adductor pollicis muscle at 50% of maximal voluntary contraction in a 6-s on, 4-s off cycle. To assess fatigue, a maximal isometric twitch was elicite...
BACKGROUND Postoperative fatigue is common, even after uncomplicated operations. Various theories have been presented regarding its aetiology, each suggesting different possible interventions. The purpose of this review was to identify all studies that have assessed interventions for postoperative fatigue and to evaluate these interventions using meta-analytical techniques. METHODS Randomized...
driver fatigue may impose the risk of crashes and is a leading cause of death in transportation industry. this study aimed to detect driver cognitive fatigue based on changes in eeg frequency bands in non-professional drivers during a simulated driving task. in a descriptive-analytical study, 12 healthy male car drivers took part in a two hour driving session on a simulated monotonous road, whi...
The American Geriatrics Society, with support from the National Institute on Aging and the John A. Hartford Foundation, held its fifth Bedside-to-Bench research conference, "Idiopathic Fatigue and Aging," to provide participants with opportunities to learn about cutting-edge research developments, draft recommendations for future research, and network with colleagues and leaders in the field. F...
The growing number of fatigue related accidents in recent years has become a serious concern. Accidents caused by fatigue in transportation and in mining operations involving heavy equipment can lead to substantial damage and loss of human life. Preventing such fatigue related accidents is highly desirable, but requires techniques for continuously estimating and predicting the operator’s alertn...
