False Alarm Tests of Big Machinery

3D Positioning and Tracking using IR-UWB Radars

This video shows a real-time 3D positioning and tracking experiment using eight quasi-monostatic IR-UWB radars. Both 1D and 3D Kalman filters are used for the smooth 3D estimations. The algorithm used in this experiment is designed to be computationally more efficient than conventional 3D algorithms so that real-time operations can be feasible, even though multiple quasi-monostatic radar modules are employed.

People Counting inside an Elevator Using XeThru UWB radar

This video shows another people counting experiments using an IR-UWB radar sensor in an elevator where all four side walls are made of metal. Although there exist severe multipath interferences as well as ping-pong effects of radio signals, we could maintain a reasonable level of accuracy. 

X4 Presence Detection Demonstration

The X4 UWB radar SoC by Novelda is put to the test and pushed through different occupancy scenarios. The X4 UWB radar SoC from Novelda is a ground-breaking technology development that enhances all key radar operating metrics, including sensitivity, range, power economy and level of integration.

People Counting Using an Xethru UWB Radar Sensor

This video shows the XeThru radar sensor used for counting people in crowds. This is an improved version with a counting algorithm that works much faster compared to earlier versions.

Non contact Sleep Monitoring used to identify sleep apnea states

Part of the polysomnography data where measured using an XeThru UWB radar sensor in the Medical Center of Hanyang University, Seoul, Korea. The radar was installed on the ceiling at the distance of about 1.8m above the sleep bed.
They were able to identify sleep apnea states with reasonable accuracy.
