MRI Scanner
Magnetic resonance imaging uses a strong static magnetic field of typically 1.5 tesla and a high-frequency alternating magnetic field at the Larmor frequency of approximately 64 megahertz to tilt the spins of the hydrogen nuclei out of their alignment.
After the alternating magnetic field is turned off, the spins begin to precess freely in the static magnetic field. As they return to equilibrium, a very weak signal of approximately minus 120 dBV is detected at the receiving antennas for a duration of 30 ms to 2000 ms, depending on the tissue. Using various techniques for driving the alternating magnetic field—such as spin echo, gradient echo, and inversion recovery—it is possible to measure hydrogen-containing tissue and distinguish it in images based on its decay time. By aligning the static magnetic field gradient, the slice plane to be visualized can be freely selected.

Li-Ion Energy Storage Systems (BESS)
Li-ion energy storage systems pose significant safety risks such as fire or explosion in the event of a fault. For this reason, the battery management system (BMS) must be designed in accordance with internationally recognized functional safety standards such as IEC 61508 or ISO 13849.
The safe design of lithium-ion storage systems is not an option, but a necessity. It is essential for risk minimization, certification, and customer confidence.

Battery Electrical Vehicles (BEV)
The BMS in a battery electric vehicle monitors, controls, and protects the high-voltage battery by regulating parameters such as state of charge (SoC), temperature, and cell voltage to ensure maximum performance, safety, and battery lifespan.

Sensors
RADAR, LiDAR, and GNSS sensors enable vehicles to perceive their surroundings, detecting objects, mapping terrain, and determining position in real time to support fast, reliable decision-making. In Advanced Driver Assistance Systems (ADAS) each play distinct and complementary roles to leverage their strengths and compensate for individual weaknesses.
- RADAR
- LiDAR
- GNSS (GPS, GLONASS)
Automotive Steering
- Electric Power Steering (EPS)
- Rear Axle Steering (RAS)
Electric power steering (EPS) and rear-axle steering (RAS) improve driving dynamics through greater steering precision, better maneuverability, and better integration with ADAS functions.
With safety-related implications, our expertise covers the entire development life cycle:

- Performance testing and safety validation with everyday drivers
Chassis Systems
Chassis control systems optimize the balance between ride comfort and driving stability by continuously adapting to road conditions and dynamic driving scenarios. These systems reduce the pitching, rolling, and bouncing of the body, for example, ensuring a smoother ride and improved handling.
- Adaptive Suspension
- Active Suspension
- Air Suspension
- Double Clutch System
However, due to their direct influence on vehicle dynamics, failures in chassis control systems can pose significant safety risks, potentially leading to vehicle instability or loss of control. To mitigate these risks, we bring extensive expertise in:
- Hardware and software development for safety-critical control systems
- In-depth understanding of vehicle dynamics and driver behavior
- Functional safety engineering and validation under real-world conditions
