Sleep/Wakefulness Detection Using Tracheal Sounds and Movements.
Nature and science of sleep, 2020 The current gold standard to detect sleep/wakefulness is based on electroencephalogram, which is inconvenient if included in portable sleep screening devices. Therefore, a challenge in the portable devices is sleeping time estimation. Without sleeping time, sleep parameters such as apnea/hypopnea index (AHI), an index for quantifying sleep apnea ...

Actigraphy-based sleep/wake detection for insomniacs [PDF]
2017 IEEE 14th International Conference on Wearable and Implantable Body Sensor Networks (BSN), 2017 This paper presents an actigraphy-based approach for sleep/wake detection for insomniacs. Due to its relative unobtrusiveness, actigraphy is often used to estimate overnight sleep-wake patterns in clinical practice. However, its performance has been shown to be limited in subjects with sleep complaints such as insomniacs. Quantifying activity counts on

Receiver Design for Realizing On-Demand WiFi Wake-up using WLAN Signals
, 2012 In this paper, we design a simple, low-cost, and low-power wake-up receiver which can be used for an IEEE 802.11-compliant device to remotely wake up the other devices by utilizing its own wireless LAN (WLAN) signals.

Detection of Wake Word Jamming
Proceedings of the Sixth Workshop on CPS&IoT Security and PrivacyPersonal Voice Assistants (PVAs) such as Apple's Siri, Amazon's Alexa and Google Home continuously monitor the acoustic environment for a wake word to start interaction with the user. However, the wake word detection is susceptible to disruptions caused by acoustic interference. Interference might be by noise (e.g.

YOLOv8n–CBAM–EfficientNetV2 Model for Aircraft Wake Recognition
Applied SciencesIn the study of aircraft wake target detection, as the wake evolves and develops, the detection area of the LiDAR often shows the presence of two distinct vortices, one on each side. Sometimes, only a single wake vortex may be present. This can lead to a
