Wake Detection and Positioning for Autonomous Underwater Vehicles Based on Cilium-Inspired Wake Sensor [PDF]
SensorsThis paper proposes a method for passive detection of autonomous underwater vehicle (AUV) wakes using a cilium-inspired wake sensor (CIWS), which can be used for the detection and tracking of AUVs.

Sleep/Wake Detection by Behavioral Response to Haptic Stimuli. [PDF]
J Clin Sleep Med, 2019 Actigraphy, the tool of choice for assessment of sleep phase disorders, is insensitive to movement-free waking. This study aimed to determine whether the detection of waking could be performed by recording instrumental responses to haptic stimuli delivered by a low-cost device.Twenty adults underwent 2 nights of laboratory polysomnography (PSG) while ...

Wake Word Detection with Streaming Transformers [PDF]
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021 Modern wake word detection systems usually rely on neural networks for acoustic modeling. Transformers has recently shown superior performance over LSTM and convolutional networks in various sequence modeling tasks with their better temporal modeling power.

A New Automated Ship Wake Detector for Small and Go-Fast Ships in Sentinel-1 Imagery
Remote Sensing, 2022 In the field of maritime surveillance with satellite imagery, ship detection with Synthetic Aperture Radar (SAR) is largely successful with the exception of those cases where the target Radar Cross Section (RCS) results very low and hard to detect.

Detecting wakefulness in anaesthetised children [PDF]
Canadian Journal of Anaesthesia, 1997 To investigate the suitability of the isolated forearm technique in detecting wakefulness in children aged 8 to 16 yr.Forty-one healthy English speaking children were enrolled. Following intravenous induction of anaesthesia with 5-7 mg.kg-1 thiopentone iv, but before administration of 1-1.5 mg.kg-1 succinylcholine a pneumatic tourniquet was inflated to
