Semantic compression for constrained sensor links.
Peripheral Technologies also develops a training-free semantic codec for bandwidth- and power-constrained sensor links. Instead of reconstructing every bit, the codec transmits the task-relevant meaning a decision system needs. Validated on 100+ datasets across acoustic, biomedical, industrial, and environmental signals, with a zero-malloc C11 implementation running on Cortex-M hardware and live sub-GHz LoRa transmission. Currently at TRL 4. We pursue this work through SBIR/STTR and DoD research channels. Technical details available under NDA.
Outcomes
| Outcome | Why it matters |
|---|---|
| Longer battery life on sensor nodes | Smaller payloads mean fewer radio wake-ups on battery-powered nodes. |
| Graceful degradation under jamming and packet loss | Task-relevant meaning survives bit errors where conventional codecs fail hard. |
| One codec across six sensor families | Acoustic, biomedical, industrial, environmental, network, and bus-level signals, with no per-domain retraining. |
| No training data required | The codec is built from lattice geometry, so there is no training corpus to gather or protect. |
| Reference Python and byte-identical C | Zero-malloc C11 that matches the reference implementation byte for byte. Auditable, not opaque. |
TRL 4, looking for the right Phase I.
Laboratory validation and a component demonstration are done: a hundred-plus datasets, an embedded C11 implementation on Cortex-M class hardware, and live sub-GHz LoRa transmission. The next step is validation against a sponsor's operational signals and radios.
We pursue this through SBIR and STTR topics, DoD research channels, and agreements with labs and sensor makers. Technical details, evaluation harnesses, and telemetry are available under NDA.
