Abstract:
Disclosed herein are methods and devices for monitoring a subject at rest. One such device comprises a sensing unit having a fluid-filled bladder configured to be placed under a substrate on which the subject lays and a sensor in fluid communication with the bladder. The sensor is configured to sense pressure variations within the bladder generated by a heart beat, respiration and body weight of the subject and to generate signals indicative of the pressure variations. A processor is configured to receive the signals and to determine and generate output indicative of the subject's heart beat and respiration and presence on the substrate. An external device is configured to display one or more of the output.

Claim (Index 16):
A sensor apparatus comprising:\n an air bladder configured to be positioned under a mattress and above a bed frame, wherein the air bladder has a bladder top and a bladder bottom that combine to define an air chamber of the air bladder, wherein the chamber of the air bladder has a substantially rectangular outer perimeter portion when viewed from above or below the air bladder, wherein the outer perimeter portion has first, second, third, and fourth edges, wherein the air bladder defines a bladder inlet to the air chamber that is positioned along the first edge of the outer perimeter of the air chamber of the air bladder, wherein the bladder top is connected to the bladder bottom so as to define a plurality of channels that extend longitudinally in a direction that is parallel to the second and fourth edges and that is perpendicular to the first and third edges, wherein the air bladder is configured to allow air flow between the bladder inlet and the channels, wherein the air bladder is sized smaller than a surface area of a mattress and is sized large enough to sense a user's heart and lungs when positioned under a mattress, wherein the air bladder is made of an inflatable and substantially air-tight plastic material; a pressure control unit comprising:\n a housing made of a rigid plastic material; \n an electrical air pump positioned in the housing, in fluid communication with the bladder inlet of the air bladder, and operable to control fluid pressure within the air bladder; \n an air pressure sensor positioned in the housing, in fluid communication with the bladder inlet of the air bladder and configured to sense fluid pressure of the air bladder and to generate a sensor signal as a function of sensed fluid pressure of the air bladder, wherein the air pressure sensor is configured to sense incident fluid pressure waves caused by cardiopulmonary activity of a the user lying on a top of the mattress; \n a processing unit integral with the air bladder and in electrical communication with the air pressure sensor and the electrical air pump and configured to:\n receive the sensor signal from the air pressure sensor; \n operate the electrical air pump to maintain a predetermined pressure within the air bladder; and \n convert the received sensor signal to data; \n a wireless transmitter in data communication with the processing unit, integral with the air bladder, and configured to transmit the data using at least one of an IEEE 802.11 protocol and a BLUETOOTH protocol; and a cover configured to cover the air bladder for comfort without substantially insulating the sensor apparatus from sensing vibrations generated by heart and lung function of the user lying on the top of the mattress.
