Any foregoing device, wherein the device comprises from one to ten pressure sensors in each zone, e.g., two to eight pressure sensors, two to six pressure sensors, three to six pressure sensors, four to six pressure sensors, or, e.g., six pressure sensors, in each zone.

Any foregoing device, wherein the pressure sensors are positioned for detection of pressure in body regions prone to ulcer formation, e.g., one or more of the elbow, inner knees, rear of the head, back of the shoulders, lower back, hip, greater trochanter, and heel.

Any foregoing device, further comprising one or more temperature sensors.

Any foregoing device, wherein the perforated airflow manifold is connected to a source of compressed air (e.g., a compressor integrated with the controller, or, e.g., an external source of compressed air), optionally, wherein the pressure of the air provided is controllable (e.g., controllable by an external means, or controllable by the control unit).

Any foregoing device, wherein the perforated airflow manifold provides airflow to one or more zones of the device when instructed by the control unit.

Any foregoing device, wherein the detection of a pressure exceeding a threshold value in a particular zone will result in the control unit actuating the vibrational motors and/or air flow to said zone, optionally wherein said threshold pressure is determined by the user (e.g., the patient or health care provider).

Any foregoing device, wherein the detection of a temperature exceeding a threshold value in a particular zone will result in the control unit actuating the vibrational motors and/or air flow to said zone, optionally wherein said threshold temperature is determined by the user (e.g., the patient or health care provider).

Any foregoing device, wherein the control unit measures pressure and/or temperature at each sensor at a predetermined schedule (e.g., every one minute, two minutes, three minutes, four minutes, five minutes, ten minutes, fifteen minutes, twenty minutes, etc.), optionally, wherein the control unit records each such measurement in a storage medium (e.g., a hard drive, floppy disk, flash drive, flash memory, etc.), and optionally, wherein the control unit can recall and compare previous pressure and temperature records to current measurements.

Any foregoing device, wherein the control unit shuts off the vibrational motors and/or air flow to a particular zone after a pre-determined running time (e.g., one minute, two minutes, three minutes, four minutes, five minutes, ten minutes, fifteen minutes, twenty minutes, etc.), optionally wherein the pre-determined running time is selected to prevent or avoid overheating of the motors.

Any foregoing device, wherein the control unit shuts off the vibrational motors and /or air flow to a particular zone when the pressure and/or temperature sensors in that zone have detected that the pressure and/or temperature has fallen below a preset threshold value, optionally wherein said threshold value(s) is/are determined by the user (e.g., the patient or health care provider).

Any foregoing device, wherein the device further comprises a uniform layer of pressure-re-distributing material, e.g., a foam or gel, for example, a viscoelastic foam or gel.

Any foregoing device, wherein the device comprises one or more layers, wherein at least one layer contains the vibrational motors, and another layer contains the pressure sensors, and another layer contains the airflow manifold.
