Thomas Langer-Consultant for AI, Electronics Development and System Integration

AI-driven automation of purchasing on a printing company's website, including selecting delivery times, order options, ordering, payment, and uploading print data from the Lumiz Cloud.

Business concept developed together with another potential co-founder: on-premise AI system with a consumer GPU and retrieval augmented generation, envisioned as an SME product.

My responsibilities included technical feasibility assessment, market analysis, target group definition, estimation of the addressable market, and concept development.

Proof of concept: selection and procurement of the proof-of-concept hardware, implementation of the AI system's inference part with an Nvidia GPU, OpenAI gpt-oss-20b LLM, Ollama and Open WebUI, along with performance tests.

Multimodal extension: PyTorch environment for multimodal AI models (image and text), evaluation of the inference model Qwen3-VL-8B and the embedding model tomoro-colqwen3-embed-4b.

Evaluation of Langflow for workflow automations with AI agents.

AI workshop with training, practical examples for processing ASMPT-specific data formats using machine learning and generative AI, AI use case identification and evaluation.

Internal tool for AUTOSAR XML generation: AI-driven documentation of the transformation logic, extensions, optimizations, and bug fixes.

Standardization of the system integration test environments and creation of the related Vector CANalyzer configurations to increase efficiency by unifying test rigs.

Design of a Python client for analyzing messages in the internal Ethernet field bus protocol.

Development of a Python tool to convert pick-and-place machine trace data for Vector CANalyzer.

LIDAR Compute Module: Provided bring-up support, lab tests, failure analysis, identification of all hardware data sources, and requirement creation for the specialized diagnostic software.

As function owner of the specialized diagnostic software: developed the concept for the LIDAR system diagnostics, managed features, requirements, tasks, reviews, and defects; oversaw implementation in the AUTOSAR LIDAR Compute Module software and in the Vector CANoe-based test software; designed the CANoe GUI and wrote CAPL code. This diagnostic software enabled design verification at an early development stage.

Signal integrity and power integrity simulations for IC packages and PCBs. Found an RF design error on an evaluation board; the design fix prevented delays in IC evaluation and saved on board redesign costs. Developed a dedicated PCB clock distribution network to run a test IC despite a clock driver with extremely steep edges.

Simulations and optimizations of chip-to-PCB transitions for 77 GHz ADAS radar MMICs.

EM field simulations to extract models of IC packages and PCBs.

Created MATLAB and Python programs.

Set up and led a team of up to 10 staff. Established the development process including CAD software, component libraries, lab infrastructure, Subversion repository, and quality assurance.

Managed projects focused on achieving very demanding targets.

Created and reviewed specifications for 3GPP UMTS and LTE systems, modules, and RF filters. Developed module architectures in collaboration with system engineering and ASIC designers.

Oversaw about 240 builds from DC to 3.6 Gb/s including design, assembly, commissioning, evaluation, and optimization, and supported system integration: evaluation boards for Ubidyne GaAs, SiGe, and CMOS ASICs, multistandard transceiver modules for active antennas at 900 MHz and 2.1 GHz.

Selected technologies for PCBs, ceramic substrates, RF filters, and housings.

Collaborated with EMS companies, PCB manufacturers, Toshiba, the Ferdinand Braun Institute, and antenna makers Kathrein, Andrew, and Huber & Suhner.

Equalizer ICs for backplane systems up to 12.5 Gb/s: calculated mixed-mode S-parameters and crosstalk for backplane systems and designed adaptive equalizers at the system level.

10 Gb/s and 40 Gb/s fiber-optic systems: managed collaborations with two universities and ran system simulations to define requirements for electrical equalizer ICs.

• 1 Gb/s 8:32 CMOS demultiplexer IC: designed BGA packaging, test strategy, and PCB development.

Generated electrical transients in the picosecond range using nonlinear diode lines. Based on this work, completed a part-time PhD at TU Berlin in 2001.

Modeled, simulated, laid out, and measured GaAs MMICs. Developed GaAs MMIC sampling circuits with transients down to 7 ps and harmonics up to 140 GHz.

Performed electromagnetic field simulations of coplanar transmission structures up to 1 THz.

Developed a broadband low-power transimpedance amplifier GaAs MMIC for 100 MHz to 6 GHz.

Design and setup of ultra-wideband amplifiers 10 kHz – 16 GHz, including developing and implementing a new method for temperature compensation.
