Embedded sensing and instrumentation, connecting physical measurement to the analytics layer — and the deployment engineering that makes that work outside a laboratory.

Sensing

MEMS accelerometers, environmental sensors and custom instrumentation, selected and calibrated for the measurement actually required rather than the specification sheet. In field deployment the constraints are power, connectivity and drift, and none of them are visible on a bench.

Deployment

The recurring lesson from this period, and one that carries directly into how we validate simulation today: a system that performs well under controlled conditions has demonstrated very little. What matters is the behaviour at the edges — and knowing where those edges are.
