In this paper, we introduce a novel real-time and contact-free sensor system, Helena, that
can be mounted on a bed frame to continuously monitor sleep activities (entry/exit of bed …

In this article, the framework and architecture of a Subsurface Camera (SAMERA) are
envisioned and described for the first time. A SAMERA is a geophysical sensor network that …

This paper presents an innovative decentralised seismic tomography computing paradigm
in cyber-physical sensor systems, where each sensor node computes the tomography …

Monitoring sleep quality and status is important to learn health condition for improvement
and prevent sleep apnea. A bed-mounted seismometer system is proposed to monitor the …

We present an automatic arrival picking workflow as a preprocessing for the real-time
microseismic event location, based on a data-adaptive spectral subtraction filtering and a …

The present disclosure relates to a monitoring system configured to monitor the activities of
individuals without having to keep the surrounding area under the surveillance of a camera …

Seismic data has been historically used in seismology for geological, structural and military
monitoring applications. Due to all activities, natural and human-made, generate vibration …
