Abstract: A support surface system provides alternating pressure therapy and low air loss therapy simultaneously using a single pump. The system includes a plurality of cells. Each cell has a foam-filled lower chamber and an upper chamber. Fluid communication between the lower and upper chambers is controlled by a normally closed valve that opens if the pressure within the lower chamber exceeds a predetermined threshold pressure. Pressurized air is alternatingly supplied to the lower chambers of a first subset of cells and the lower chambers of a second subset of cells, thereby providing alternating pressure therapy. When the pressure in the lower chamber exceeds the threshold, the valve opens to allow air from the lower chamber to flow into the upper chamber. Air is expelled from the upper chamber through perforations therein, to remove moisture and humidity and possibly reducing the temperature of the micro-climate beneath a patient.

Abstract: A seat having a backrest and a seat cushion is provided with at least one adjusting element on both sides of the longitudinal center plane of the seat. By alternatingly actuating the adjusting elements in the two halves of the seat, mobilization of the spinal column of a seat user occurs. In order to increase the acceptance of such a mobilization, which requires comparatively long stroke lengths of the adjusting elements to achieve a physiological effectiveness, an accustomization phase occurs before the action phase. During the accustomization phase, the adjusting elements exercise, for example, only about half of the stroke during the action phase. Preferably, a transition phase may be interposed between the accustomization phase and the action phase.

Abstract: A human body support, such as a chair, has a plurality of support segments that are arranged in an array. Each support segment has a protrusion elevation that is independently variable and controllable in its distance of protrusion elevation against the supported human body. A sensor is connected to a human body on the support and senses a human body parameter that can indicate the presence of drowsiness. A controller analyzes the sensed parameter to detect whether the sensed parameter is within a range indicating the presence of drowsiness. The controller applies a wave of varying segment protrusion elevation against the human body in response to the detection of drowsiness. The wave progresses in a direction from an inferior location on the human body toward a more superior location. Alternatively, a wave of electrical stimuli is applied by similarly positioned electrodes and causes periodic tightening and relaxing of proximate muscles.
