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 18):
A method of sensing one or more sleep parameters, the method comprising:\n placing an air bladder under a mattress, 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 air 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; controlling, by an electrical air pump in fluid communication with the bladder inlet of the air bladder, operable to control fluid pressure within the air bladder, and housed within a housing made of a rigid plastic material, a fluid pressure within the air bladder; sensing, by an air pressure sensor positioned in the housing, in fluid communication with 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, fluid pressure of the air bladder, wherein sensing the fluid pressure within the air bladder comprises sensing incident fluid pressure waves caused by cardiopulmonary activity of a user lying on the mattress and wherein the air bladder is covered by a cover configured to cover the air bladder for comfort without substantially insulating the pressure sensor from sensing vibrations generated by heart and lung function of a user on a top of the mattress; generating, by the air pressure sensor, a sensor signal as a function of sensed fluid pressure of the air bladder; receiving, by a processing unit integral with the air bladder and in electrical communication with the air pressure sensor, the sensor signal from the air pressure sensor; converting, by the processing unit, the received sensor signal to data indicative of the user's heart rate, the user's respiratory rate, and the user's time in bed; and transmitting, by a wireless transmitter in data communication with the processing unit and integral with the air bladder, the data.
