Abstract
A patient support system for supporting a patient includes a core support structure which includes supportive foam. The support structure has an upper surface and a lower surface. A radar apparatus, including at least one antenna situated beneath the upper surface and spatially separated therefrom, is adapted to emit a pulse which travels through the support structure and is reflected, by either the upper surface or a surrogate thereof, as a reflected signal back to the radar antenna. The emitted pulse and reflected signal comprise a ranging signal. The patient support system also includes circuitry that determines a life parameter of the core support structure as a function of at least the ranging signal. The patient support system also includes an RFID tag having a memory. The RFID tag is in communication with the circuitry.
