Recognizing Bedside Events Using Thermal and Ultrasonic Readings
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-09)Falls in homes of the elderly, in residential care facilities and in hospitals commonly occur in close proximity to the bed. Most approaches for recognizing falls use cameras, which challenge privacy, or sensor devices attached to the bed or the body to recognize bedside events and bedside falls. We use data collected from a ceiling mounted 80 60 thermal array combined with an ultrasonic sensor ... -

Parabolic reflector for focusing of underwater acoustic waves
(Master thesis; Mastergradsoppgave, 2017-06-15)Kongsberg Maritime has produced a transponder placed on the seabed designed for receiving and transmitting sound waves from vessels and ROVs. The soundwaves contain data regarding depth and location, and can be transformed to energy thus increasing the transponder battery lifetime. The transponder can only receive a small amount of energy, since its receiving area is small. This project aims to ... -
