Beschreibung
Zusammenfassung:	A support surface overlay system includes a support surface overlay and a control system. The support surface overlay includes at least one selectively inflatable compartment. The control system includes a pneumatic controller configured to inflate and deflate the at least one selectively inflatable compartment. The control system also includes a memory, a sensor, and a processor. The memory is programmed with a predetermined data indicative of an operating parameter of the system vs. time with the support surface overlay in an unloaded state. The sensor is configured to detect and provide signals indicative of the operating parameter of the system vs. time during inflation and/or deflation of the at least one selectively inflatable compartment. The processor is configured to compare the predetermined data to the data provided by the sensor and to determine whether or not a load is present on the support surface overlay based on the comparison.
