Services

Engineering services for long-lived IoT & embedded systems

From system concept through engineering to the product's end of life: we support your product throughout its entire lifecycle.

System & Lifecycle

An electronic product that stays stable and secure for years needs a well-considered system concept. We help you design and plan complex electronic systems and support your products throughout their lifecycle, from requirements definition and system architecture to product revisions, updates and obsolescence management.

  • Systems Engineering

    We support you in planning. Our experience ranges from battery management systems and professional LED lighting to high-speed measurement and complex user interfaces.

  • Systems- & Lifecycle-Management

    After the release to series production: security updates, discontinued components, re-testing after changes.

Engineering

We develop hardware, embedded software, cloud connectivity and AI to your specific requirements. We bring the individual engineering disciplines together into one coherent solution and, where it makes sense, build on proven technologies and our own platform modules.

  • AI Engineering

    AI on the device, AI in the cloud and AI in your engineering — from the first experiment to a model that is maintained in the field.

  • Embedded Software Engineering

    Bare-metal firmware, RTOS applications and embedded Linux systems for devices with a long service life.

  • IoT-Cloud Engineering

    Connecting the device to your systems or to qdCloud: fleet management, log analysis, OTA updates.

  • Hardware Engineering

    Simple, robust solutions. We turn demanding requirements for function, production cost and regulatory approval into stable series products.

The most expensive mistakes happen between the disciplines.

Quality, Safety & Security

We build quality, safety and security into the development process from the start. Verification and testing, functional safety, cyber security and EMC pre-compliance lay the groundwork for reliable, safe and maintainable electronic products.

  • Verification

    Unit tests, SiL and HiL tests on the target hardware, end-of-line test station with qdTest.

  • Functional Safety

    Up to SIL 3 under IEC 61508 and up to PL e under ISO 13849. For medical devices, we support classes I, IIa and IIb under the MDR.

  • Cyber Security

    Cyber Resilience Act, IEC 62443, secure boot, and monitoring known vulnerabilities throughout the service life.
