TL;DR: A fiber optic monitor that utilizes optical phase interferometry to monitor a patient's vital signs such as respiration, cardiac activity, blood pressure and body's physical movement is presented in this paper.

TL;DR: A communication system can include a transmitter which transmits a signal, and at least one sensing device which receives the signal, the sensing device including a line contained in an enclosure, and the signal being detected by the line through a material of the enclosure as mentioned in this paper.

TL;DR: A fiber optic monitor that utilizes optical phase interferometry to monitor a patient's vital signs such as respiration, cardiac activity and body's physical movement is proposed in this paper.

TL;DR: In this article, a method and system for monitoring the operation of downhole equipment, such as electrical submersible pumps, is described, which relies on the use of coiled fiber optic sensors such as hydrophones, accelerometers, and flow meters.

TL;DR: In this article, a light source that drives an optical fiber positioned within a borehole is used to obtain an acoustic signal for each of multiple points along the borehole, and one or more processors operate to determine microseismic event direction, distance, and intensity based at least in part on phase information of said acoustic signals.
