Prevent in-cabin accidents with 3D Ultrasonic Sensing

Breathing detection based on 3D ultrasound technology

More than 800 children in parked cars have died of heatstroke in the United States in the last two decades because they were forgotten in the car.

By 2025, most automakers want to implement a system that prevents this terrible scenario through better in-cabin monitoring.

Differentiate between static objects and living people

With the help of our 3D ultrasound technology, we can recognize living objects in cars. In this way, we can avoid accidents by detecting dogs and children that have been forgotten in a parked car, as was often the case in the past.

This is made possible through the detection of breathing movements occurring in the respective seats. Our sensor system records the movements of the chest with the help of ultrasound and compares these with a stored breathing pattern.

If these are the same, a living object is recognized.

In addition, the respective scene is stored in its empty state, which our sensor system uses to recognize whether a new object has been added or removed. Thus, also non-living objects can be detected.

Avoid false triggering of the sensor system

Setting certain areas of detection

No disturbing optics through invisible sensors

The system is usable under the fabric of the car roof

Protect your
privacy

Our sensor system collects only 3D data, unlike a camera, for example

All at a scalable price per system

Cost-efficient and based on proven ultrasonic technology

AI-algorithms enable reliable breathing detection

In the raw data on the left side, you can see the comparison of our 3D ultrasound data with a Kinect camera. The first step is to capture the scene and the person in it. After this, our system clusters the relevant datapoints and extracts the movement of the clusters over time. This movement is then compared to a conventional breathing pattern.

On the right side, you can see the motion caused by breathing alone, which was recorded with the help of our ultrasound sensors.

Additional in-cabin use-cases

Our sensor system is also capable of detection gestures and can be used for 3D area surveillance, enabling more than one use case with a single sensor system.

Gesture control

Comfort features like simple gesture recognition for passengers based on 3D ultrasonic technology.

Area surveillance

Safety features like access detection of unauthorized persons.
