BOES: Building Occupancy Estimation System Using Sparse Ambient Vibration Monitoring
In this paper, we present a room-level building occupancy estimation system (BOES) utilizing low-resolution vibration sensors that are sparsely distributed. Many ubiquitous computing and building maintenance systems require fine-grained occupancy knowledge to enable occupant centric services and optimize space and energy utilization. The sensing infrastructure support for current occupancy esti...
متن کاملMonitoring a Building Using Deconvolution Interferometry. II: Ambient- Vibration Analysis
Application of deconvolution interferometry to earthquake data recorded inside a building is a powerful technique for monitoring parameters of the building, such as velocities of traveling waves, frequencies of normal modes, and intrinsic attenuation. In this study, we apply interferometry to ambient-vibration data, instead of using earthquake data, to monitor a building. The time continuity of...
متن کاملLow-noise Linear and Angular Motion Sensors for Vibration Monitoring
* The presented researches was supported by Russian Ministry of Science and Education, project ID RFMEFI57814X0013. Abstract— This article reviews on the development of a new category motion sensors for vibration monitoring including linear and angular accelerometers based on molecular electronic transducer (MET) technology. This technology utilizes liquid not only as an inertial mass but also ...
متن کاملOn the difference between empirical mode decomposition and Hilbert vibration decomposition for earthquake motion records
In this paper, Empirical mode decomposition (EMD) and Hilbert vibration decomposition (HVD) are employed to process various different types of non-stationary and nonlinear vibration. The properties of these two methods are systematically analysis by comparing the efficacy in some numerically simulated signals. Meanwhile these two methods are used to analyze a Wenchuan earthquake strong ground m...
متن کاملOn energy harvesting from ambient vibration
Future MEMS devices will harvest energy from their environment. One can envisage an autonomous condition monitoring vibration sensor being powered by that same vibration, and transmitting data over a wireless link; inaccessible or hostile environments are obvious areas of application. The base excitation of an elastically mounted magnetic seismic mass moving past a coil, considered previously b...
