    摘要： A method for detecting occupant position change on a support surface includes establishing a rate of change of pressure in a head end test zone and in a foot end test zone, comparing the head end rate to at least one head end rate limit, comparing the foot end rate to at least one foot end rate limit, and inferring, in response to the comparing steps, whether or not occupant migration has occurred. An associated occupant support includes a frame and a mattress. The mattress includes head and foot zones each having at least one pressurizable bladder. The support also includes a controller adapted to compare a head end rate of pressure change to a head end rate limit, to compare a foot end rate of pressure change to a foot end rate limit, and to infer, in response to the comparing steps, whether or not occupant migration has occurred.

    摘要： A system for monitoring a patient on a hospital bed includes load cells and a controller for detecting patient movement on, exit from, and impending exit from the hospital bed, including movement across or outside a virtual boundary or region located on the bed. The controller is configured to detect changes in the distribution of patient weight among the load cells. The controller is also configured to accommodate the installation or removal of medical equipment or other tare weights on the bed, head incline adjustment, and bed frame deformation or other changes in the system causing redistribution of weight among the load cells, while minimizing false alarms. A caregiver may select between various patient monitoring modes and remotely monitor patient movement relative to a reference load cell distribution, impending patient exit from the bed and patient exit from the bed.

Pressures in an air mattress may be controlled based on signals from the load cells.
