Abstract
Abstract A valving system and modified anti-G flight suit are disclosed which operate in either of two modes. In an anti-blackout mode, pneumatic bladders in the flight suit are simultaneously inflated. In an anti-fatigue mode, the bladders are sequentially inflated in a repeated cycle so as to prevent pooling of blood and other body fluids in the leg and lower seat area.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
In combination with a flight suit having pneumatic bladders for applying pressure to desired areas on a person wearing the flight suit, a plurality of inlet conduits, each bladder communicating with one of said plurality of inlet conduits. a device for pressurizing the bladders in a desired sequence, said device comprising: a plurality of sequencing valves in one-to-one correspondence with the inlet conduits, each sequencing valve including an inlet port and an outlet port; first connecting means for connecting the outlet port of each sequencing valve to a corresponding inlet conduit; timing control means for providing control signals to the sequencing valves in accordance with the desired sequence for pressurizing the bladders; and second connecting means for connecting the inlet ports to a pneumatic pressure source.
Claim 2
Dependent Claim
126 words
In combination with a flight suit having pneumatic bladders for applying pressure to desired areas on a person wearing the flight suit, a plurality of inlet conduits, each bladder communicating with one of said plurality of inlet conduits. a device for pressurizing the bladders in a desired sequence, said device comprising: a plurality of sequencing valves in one-to-one correspondence with the inlet conduits, each sequencing valve including an inlet port and an outlet port; first connecting means for connecting the outlet port of each sequencing valve to a corresponding inlet conduit; timing control means for providing control signals to the sequencing valves in accordance with the desired sequence for pressurizing the bladders; and second connecting means for connecting the inlet ports to a pneumatic pressure source.
Claim 3
Dependent Claim
23 words
The device of claim 1 in which the second connecting means comprises a pressure regulator adjustable by the person wearing the flying suit.
Claim 4
Dependent Claim
21 words
The device of claim 1 which further comprises third connecting means for connecting the inlet conduits to the pneumatic pressure source.
Claim 5
Dependent Claim
34 words
The device of claim 3 in which the third connecting means comprises an anti-G valve which opens in response to an acceleration force on the person wearing the flying suit exceeding a predetermined limit.
Claim 6
Dependent Claim
43 words
The device of claim 4 in which the timing control means is responsive to an override signal from the anti-G valve, the sequencing valves being closed when the override signal is asserted, the override signal being asserted when the anti-G valve is open.
Claim 7
Dependent Claim
121 words
A sequentially pressurized flight suit comprising: a flight suit garment having pneumatic bladders for applying pressure to desired areas on a person wearing the garment and a plurality of inlet conduits, each bladder communicating with one of said plurality of inlet conduits in the garment; a plurality of sequencing valves in one-to-one correspondence with the inlet conduits, each sequencing valve including an inlet port and an outlet port: first connecting means for connecting the outlet port of each sequencing valve to a corresponding inlet con- duit; timing control means for providing control signals to the sequencing valves in accordance with a desired sequence for pressurizing the bladders; and second connecting means for connecting the inlet ports to a pneumatic pressure source.
Claim 8
Dependent Claim
121 words
A sequentially pressurized flight suit comprising: a flight suit garment having pneumatic bladders for applying pressure to desired areas on a person wearing the garment and a plurality of inlet conduits, each bladder communicating with one of said plurality of inlet conduits in the garment; a plurality of sequencing valves in one-to-one correspondence with the inlet conduits, each sequencing valve including an inlet port and an outlet port: first connecting means for connecting the outlet port of each sequencing valve to a corresponding inlet con- duit; timing control means for providing control signals to the sequencing valves in accordance with a desired sequence for pressurizing the bladders; and second connecting means for connecting the inlet ports to a pneumatic pressure source.
Claim 9
Dependent Claim
22 words
The device of claim 6 in which the second connecting means comprises a pressure regulator adjustable by the person wearing the garment.
Claim 10
Dependent Claim
21 words
The device of claim 7 which further comprises third connecting means for connecting the inlet conduits to the pneumatic pressure source.
Claim 11
Dependent Claim
33 words
The device of claim 8 in which the third connecting means comprises an anti-G valve which opens in response to an acceleration force on the person wearing the garment exceeding a predetermined limit.
Claim 12
Dependent Claim
43 words
The device of claim 9 in which the timing control means is responsive to an override signal from the anti-G valve, the sequencing valves being closed when the override signal is asserted, the override signal being asserted when the anti-G valve is open.
Claim 13
Dependent Claim
50 words
The device of claim 10 in which each bladder comprises an inlet/venting valve which allows the bladder to be inflated in response to pneumatic pressure in the associated inlet conduit exceeding a predetermined pressure and vents air out of the bladder when the pneumatic pressure is below the predetermined pressure.
