Accurate and comprehensive nursing documentation is essential to ensure quality patient care. To streamline this process, we present SONAR, a publicly available dataset of nursing activities recorded using inertial sensors in a nursing home. The dataset includes 14 sensor streams, such as acceleration and angular velocity, and 23 activities recorded by

Sonar Systems and the Sonar Equation
2019The purpose of this chapter is to introduce several basic concepts related to sonar systems and their analysis through the sonar equation. The components of a sonar system are described, including monostatic, bistatic, and distributed systems. Examples of how they can be used to localize objects of interest are presented for active and passive systems.

2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004
This paper describes a new data association technique for the interpretation of wide-beam sonar measurements. The goal is to group sets of returns that originate from the same surface of an object. We consider the case of a moving observer that obtains range and bearing measurements of curved and/or faceted objects with binaural sonar operating in the ...

Research of new concept sonar-cognitive sonar
Journal of Marine Science and Application, 2011The performance of a sonar system is closely related to the marine environment and the target characteristics. When dealing with the echoes of a traditional active sonar system, the sonar designers often do not take into account the influence of the environmental information and prior knowledge perceived by sonar receivers, making it difficult to ...

Sonar was invented by copying bats' and dolphins' echolocation systems, but the dominant approaches taken to sonar systems today tend to focus on imagery and resolution. In this paper we explore a bio-inspired approach to sonar and sonar signal processing. Conventional sonars use narrowband pulses.

Proceedings of IEEE International Conference on Robotics and Automation, 2002
Develops theoretical and practical techniques to recover the pose of planar surfaces with minimal sensor readings and motion. A proof is given that two sonar readings suffice to precisely locate a single planar surface that returns the sonar's signal.

Sonar—The story of an experiment
Ultrasound in Medicine & Biology, 1974THERE are two main reasons for choosing a title such as this. Firstly it is necessary to put on record how this lengthy experiment came about. A combination of accident, coincidence and any amount of good luck seems to have driven us inexorably onwards.
