Projects from industry and research in which nabla B or Stephan Bökelmann played or plays a major role. Many customer projects are under NDA and are missing here — ask us if you need references from your industry.
Programmable M12-PoE switch, router and Linux compute node for industrial edge data acquisition: 7 sealed PoE ports, 8-core ARM, Yocto Linux with documented SBOM. System architecture, PoE-first concept, M12 cabling specification and EMC certification.
Measurement electronics and monitoring infrastructure for solder-profile creation and continuous process monitoring on reflow ovens (Productronica Innovation Award 2023): battery-powered temperature-profiling electronics with Wi-Fi, telemetry and observability stack for predictive assessment of solder-quality factors, cloud integration. Including EMC certification in China.
Simplified digital oscilloscope that makes waveform diagnostics usable in everyday automotive workshop practice. Grown out of the aw4null research programme, patent pending.
Embedded instrumentation for electrochemical impedance spectroscopy in the field — detecting biofilms in river systems across the continental US.
Multiple test stands for characterising HV-MAPS silicon sensors for minimum-ionizing particles, plus building up a wire-bonding production line.
Open path from JTAG bring-up without FSBL via mainline U-Boot to a Yocto Linux in QSPI flash that fetches its own updates — deploying hardware like software.
Current sensing and analytics for railway-switch diagnostics and condition monitoring, e.g. in Deutsche Bahn's DIANA system.
PCB design for an embedded vision system with an AI accelerator. Customer under NDA.
Enclosureless design for PCB cavities — mechanics, EMC and manufacturing in one concept.
Structural-stability assessment of mine-shaft closures with LoRa sensors and multi-sensor data fusion.
Camera system for remote assessment of fouling on air-fin coolers — optics, embedded electronics and analysis for use on industrial plants.
PoE-based measurement and analysis system for observing and predicting heavy-rain cells. Patent pending.
