Hospitality & Retail Shared-family mapped

ChillPulse

ColdChain Sentinel — refrigeration health from vibration signatures

Pilot refrigeration vibration-drift evidence; not failure prediction or food-safety authority.

Readiness Shared-family mapped

Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.

Evidence Supported hypothesis

Published physics or adjacent results support the hypothesis; capability-specific product and site validation are still required.

Runtime family Machine vibration

Spectral energy and drift tracking for repeatable machine vibration signatures.

When no ESP32 is connected

No compatible ESP32 stream is connected. Use the bundled Hospitality recording; it demonstrates the shared Machine vibration runtime, not independent proof of this capability.

Intended capability

Pilot this intended outcome through the shared Machine vibration family, then validate it against site-specific ground truth: Predictive maintenance for walk-in coolers, ice machines and compressors: detects bearing wear, icing-induced load change, and door-left-ajar events from vibration micro-Doppler, weeks before failure spoils stock.

This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording

A related Hospitality scene

This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.

01 The physics

Compressor and fan vibrations phase-modulate reflected CSI at their mechanical frequencies (10-40Hz and harmonics); bearing degradation broadens and shifts these spectral lines, icing changes load (frequency droop), and machine-vs-human discrimination is already proven so machinery lines are cleanly separable from staff motion.

02 Shared processing path

Micro-Doppler narrowband line extraction (10-40Hz) per machine compartment -> compartment Kalman tracking line frequency/width -> CUSUM over weeks for degradation drift; door-ajar appears as a step in the cold-room's CIR geometry baseline.

This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.

03 Validation plan

Machine-vs-human separation already class A; own long-run on a working restaurant walk-in with a seeded degrading fan and thermocouple/accelerometer ground truth over 60+ days.

04 Commercial hypothesis

'Your ice machine will fail before the holiday weekend' — condition monitoring with no sensors glued to equipment, for the multi-site restaurant facilities manager.
