Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
108 words
A system comprising an air mattress or an air cushion linked in direct air communication with an air reservoir means comprising a flexible container that includes air inlet means and air outlet means; means for propelling air through said air inlet means; means for exerting controllable pressure on said air reservoir means; means for starting said propelling means, and means for stopping said propelling means, said pressure exerting means being adapted to activate said starting means when the air volume in said reservoir falls below a predetermined minimum and to activate said stopping means when the air volume in said reservoir means rises above a first predetermined maximum.
Claim 2
Independent Claim
108 words
A system comprising an air mattress or an air cushion linked in direct air communication with an air reservoir means comprising a flexible container that includes air inlet means and air outlet means; means for propelling air through said air inlet means; means for exerting controllable pressure on said air reservoir means; means for starting said propelling means, and means for stopping said propelling means, said pressure exerting means being adapted to activate said starting means when the air volume in said reservoir falls below a predetermined minimum and to activate said stopping means when the air volume in said reservoir means rises above a first predetermined maximum.
Claim 3
Dependent Claim
54 words
The system of claim 1, said air reservoir means further comprising air volume relief means, said pressure-exerting means being adapted to activate means for opening said volume relief means when the air volume in said reservoir means rises to a second predetermined maximum, said second predetermined maximum being higher than said first predetermined maximum.
Claim 4
Dependent Claim
40 words
The system of claim 1 wherein said air reservoir means lies below a supporting platform for said air cushion or air mattress and wherein said air reservoir means is the air supply to said air cushion or said air mattress.
Claim 5
Dependent Claim
44 words
The system of claim 3 wherein said means for exerting controllable pressure on said air reservoir means comprises controllably-movable weight adapted to translate along said supporting platform, said supporting platform being movable in response to the exertion of force thereon by said movable weight.
Claim 6
Dependent Claim
21 words
The system of claim 1 wherein said pressure-exerting means is carried by a planar member that lies atop said reservoir means.
Claim 7
Dependent Claim
39 words
The system of claim 1 further comprising means for framing said air reservoir means wherein said starting means and said stopping means are linked to said framing means, and lie in the path of movement of said pressure-exerting means.
Claim 8
Dependent Claim
24 words
The system of claim 1 wherein said air mattress or air cushion is linked to said air reservoir means through said air outlet means.
Claim 9
Dependent Claim
56 words
The system of claim 7, said air mattress or said air cushion further comprising a planar surface linked to a plurality of means for holding a plurality of air tubes in a side-by-side relationship with each of said tubes linked to a common air manifold linked to the air outlet means of said air reservoir means.
Claim 10
Dependent Claim
17 words
The system of claim 1 further comprising means for controlling the pressure exerted by said pressure-exerting means.
Claim 11
Dependent Claim
35 words
The system of claim 1 wherein said means for exerting controllable pressure on said air reservoir means comprises movable weight means controllably linked to, and movable along pressure-transmitting means linked to said air reservoir means.
Claim 12
Dependent Claim
45 words
The system of claim 1 wherein said means for exerting controllable pressure on said air reservoir means comprises water-holding means lying atop said air reservoir means, said water-holding means having linked thereto means for controllably adding water to, and removing water from, said water-holding means.
Claim 13
Independent Claim
93 words
A system comprising an air mattress or an air cushion linked in direct air communication with an air reservoir means, said air reservoir means comprising a flexible container that includes air inlet means and air outlet means; means for propelling air into said flexible container through said air inlet means, means for starting and stopping said propelling means; controllable, adjustable means for continuously maintaining a predetermined, substantially constant air pressure within said system; and means for maintaining the volume of air in said system above a predetermined minimum and below a predetermined maximum.
Claim 14
Independent Claim
93 words
A system comprising an air mattress or an air cushion linked in direct air communication with an air reservoir means, said air reservoir means comprising a flexible container that includes air inlet means and air outlet means; means for propelling air into said flexible container through said air inlet means, means for starting and stopping said propelling means; controllable, adjustable means for continuously maintaining a predetermined, substantially constant air pressure within said system; and means for maintaining the volume of air in said system above a predetermined minimum and below a predetermined maximum.
Claim 15
Dependent Claim
99 words
The system of claim 12 wherein said air mattress or air cushion includes means for detecting the actual air pressure in said system, means for generating a signal representative of said actual air pressure, means for comparing said signal representative of said actual air pressure to the desired, predetermined air pressure for said system, means for generating a signal representing the difference, if any, between said signal representative of the actual air pressure in said system and the desired, predetermined air pressure; and means for utilizing the difference signal for maintaining a predetermined, desired air pressure in said system.
Claim 16
Dependent Claim
49 words
The system of claim 12 further comprising pressure-exerting means adapted to activate said starting means when the air volume in said reservoir means falls below a predetermined minimum and to activate said stopping means when the air volume in said reservoir means rises to or above said predetermined maximum.
