Abstract
A method of detecting a change in occupancy status of a fluidizable bed () includes determining () an unloaded plenum pressure value corresponding to the absence of a load on the bed, determining () a loaded plenum pressure value corresponding to the presence of an occupant on the bed, and establishing a reference (P) as a function of at least one of the unloaded plenum pressure value and the loaded plenum pressure value. A signal () is issued in response to a relationship between the reference and a value (P) representative of actual pressure in the plenum. The bed also includes a pressure sensor () for monitoring a pressure value representative of pressure in the plenum and a controller () for issuing a signal () responsive to a relationship between the monitored value and a reference value.
