Immobility clock and repositioning compliance for pressure-injury prevention
A quiet timer that knows how long a patient has lain without being turned.
The physics is solid; our own validation is scheduled.
How it works
Turning a patient creates a brief burst of movement over the bed, and the body settles in a slightly new position — both visible to WiFi waves. If no turn happens within the schedule, the clock keeps counting and reminds the team. No more paper checklists.
In 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, i.e. a flat activity manifold.

How the field becomes an answer
How we prove it
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.
Who it is for
'Auto-turn timer' — pressure-injury prevention for wound-care/CNO teams tying it to HAPI never-event reduction.
