The evidence is proven or strong, but this capability still needs a capability-specific ESP32 or Rust runtime adapter.
Intended capability
Evaluate the sensing evidence for “Immobility clock and repositioning compliance for pressure-injury prevention” in a consented, ground-truthed study. This is not a medical device, clinical monitor, diagnosis, or emergency alert.
This describes the intended outcome. Readiness is needs edge adapter, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording
A related Healthcare scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
A repositioning event is a transient whole-body micro-Doppler burst plus a measurable shift of the body's reflection centroid within the bed footprint (supine->lateral); prolonged immobility is the sustained absence of both while the mmWave radar's static-target energy at bed range stays high — a motionless patient keeps returning breathing-band micro-motion to the radar, where an empty bed returns nothing, so 'too still' and 'not there' stay distinct.
02 Shared processing path
RTI bed-cell centroid + Doppler turn-event detector (CSI) -> LD2410 static-presence hold gates the clock on an occupied-and-still bed -> compartment Kalman tracks posture-hold duration -> CUSUM/slow-drift over hours flags overdue repositioning vs. the ordered interval
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
Own-hardware bed trials with scripted turns vs. pressure-mapping mat; leverage the proven 119-day drift-control pipeline for the long-duration immobility clock and OPERAnet for posture-change feature robustness.
04 Commercial hypothesis
'Auto-turn timer' — pressure-injury prevention for wound-care/CNO teams tying it to HAPI never-event reduction; plus tier: a bed-aimed mmWave radar holds the occupied-and-still state the clock counts against.
