Last week Novelda was recognized for novelty in a new production introduction and featured the XeThru X4 UWB radar sensor as part of an Industry Showcase at the 2018 ISSCC (International Solid-State Circuits Conference). Novelda showcased its UWB radar sensor applied as an occupancy detection sensor. In addition, different signal processing schemes were presented to demonstrate different applications such as sleep monitoring and respiration monitoring, showing the versatility of the system.

“This is an important and significant recognition of Novelda and our technology, ISSCC is regarded as the flagship conference of the IEEE Solid-State Circuits Society. Members of the ISSCC Technical Program Committee nominated the significant innovations from within our industry. The long list of candidates was then put to a vote, and Novelda was selected to reach the shortlist of the most significant technical and product innovations.”

Most commercially available occupancy sensors are based on passive infrared radiation sensors capable of detecting minor movements, but lack the ability to detect the presence of stationary subjects. Pulse-based radars, such as the XeThru X4 UWB radar chip, are capable of sensing human presence based on vital signs, such as breathing and heart-rate, and offer unambiguous distance measurements. This allows for very robust positioning and real-time presence detection of even stationary or sleeping objects.

Real-time occupancy and vital signs sensing are becoming the next step in energy optimizations as it allows for better control of lighting and HVAC systems. More intelligent rooms can provide a much better user experience by avoiding false detections, and adjusting air flow and ventilation based on positioning and people count. Furthermore, vital signs data can be used for estimating sleep stages, emotional states, and health parameters, as well as safety-enhancing features, including drowsiness detection for drivers and machine operators.

Novelda offers complete radar sensors that comprises the XeThru X4 radar SoC, PCB antennas and Digital Signal Processing (DSP). Holding regulatory approvals covering the majority of the World Wide Markets, they can be integrated straight into commercial products without the end products having to run UWB RF specific tests through a Telecommunications Certification Body. This significantly shortens time to market and development cost.

The X4M300 Presence Sensor.

The X4M200 Respiration Sensor can do sleep and respiration monitoring and is targeted for applications such as sleep monitoring, baby monitoring, elderly care, and other health monitoring applications.

The X4M300 Presence Sensor can do presence detection of stationary targets up to 9.4m distance and it is targeted for a variety applications including security, lighting and HVAC control.
