Another embodiment of the invention indicates when a patient moves from a recumbent to a sitting position or raises his head from a recumbent position. A further embodiment indicates when a child gets out of bed. Another embodiment of the invention indicates when a child moves out of an area where the child is supposed to be into an area where the child is not supposed to be.
