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.

Breathing detection based on 3D ultrasound technology

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

Cost eff

All at a scalable price per system

Cost-efficient and based on proven ultrasonic technology

Detected breathing motion using 3D ultrasound (data example)


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.

Other in-cabin use case examples

Our sensor system can not only be used for passenger detection, but also for other in-cabin solutions.

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.
