in the absence of sufficient fluid pressure from the fluid moving device to the inlet side of the self-sealing valve, controlling the electromechanical device to bias the self-sealing valve to at least a partially opened position so as to regulate an amount of fluid within the inflatable device.
2. The method of claim 1, wherein the act of biasing the self-sealing valve at least partially open with the electromechanical device comprises allowing fluid to flow at least partially out of the inflatable device through the self-sealing valve.
3. The method of claim 1, wherein the act of biasing open the self-sealing valve so as to provide the fluid to the inflatable device comprises not biasing open the self-sealing valve with the electromechanical device.
4. The method of claim 1, wherein the act of biasing open the self-sealing valve to provide the fluid to the inflatable device comprises biasing open the self-sealing valve with the electromechanical device.
5. The method of claim 1, wherein the act of biasing open the self-sealing valve so as to provide the fluid to the inflatable device comprises biasing open a cover that covers the self-sealing valve.
6. The method of claim 1, wherein the act of biasing open the self-sealing valve so as to provide the fluid to the inflatable device comprises biasing on the fluid moving device to provide the fluid.
7. The method of claim 1, wherein the act of biasing the self-sealing valve to the at least partially open position comprises biasing open a cover that covers the self-sealing valve.
9. The method of claim 8, further comprising rotating an arm between a first position that seals any fluid from the fluid moving device from the first side of the diaphragm assembly of the self-sealing valve, and a second position that seals the first side of the second diaphragm assembly of the second self-sealing valve from the fluid moving device, so that only one of the self-sealing valve assembly and the second self-sealing valve assembly can be coupled to the fluid moving device at any one time.
10. An inflatable device that includes an-inflatable bladder, the inflatable device comprising:
a self-sealing valve fluidly coupled to a wall of the inflatable bladder and providing a fluid transfer port to the inflatable bladder, the self-sealing valve comprising a valve housing having a wall defining an opening through which a fluid is provided to and from the inflatable device, wherein the self-sealing valve further comprises a valve seat and a self-sealing diaphragm assembly that positions a diaphragm adjacent to the valve seat, the self-sealing diaphragm assembly configured to move at least a portion of the diaphragm at least partially away from the valve seat under bias of a fluid provided on a first (inlet) side of the self-sealing diaphragm assembly, and that is configured to close the self-sealing diaphragm assembly against the valve seat in the absence of the bias of fluid on the first (inlet) side of the self-sealing diaphragm assembly; and
an electromechanical device comprising an actuator arm, the actuator arm having a first position in which the actuator arm acts on the self-sealing diaphragm assembly to urge the at least the portion of the diaphragm at least partially away from the valve seat and a second position in which the actuator arm does not act upon the self-sealing diaphragm assembly, the electromechanical device being configured in the absence of the bias of fluid from a fluid moving device on the first (inlet) side of the self-sealing diaphragm assembly to open the self-sealing valve so as to regulate and amount of pressure within the inflatable bladder, and the electromechanical device being configured in the presence of the bias of fluid on the first (inlet) side of the self-sealing diaphragm to position the actuator arm in a second position in which the actuator arm does not act upon the self-sealing diaphragm assembly; and
the fluid moving device having an outlet fluidly coupled to the first (inlet) side of self-sealing valve so as to provide the fluid to the first (inlet) side of the self-sealing diaphragm assembly;
wherein the self-sealing valve, the electromechanical device and the fluid moving device are each located, at least in part, within a profile of the inflatable bladder.
11. The assembly of claim 10, wherein the electromechanical device is configured to bias the actuator arm to contact the diaphragm, when in the first position, so as to bias open the self-sealing valve.
12. The assembly of claim 10, wherein the electromechanical device comprises a solenoid.
13. The assembly of claim 10, wherein the fluid moving device is positioned so as to provide the fluid bias on the first side of the diaphragm assembly.
14. The assembly of claim 10, further comprising a cover that covers the self-sealing valve, the cover having a projecting arm projecting from the cover and having a surface that is configured to interact with the actuating arm of the electromechanical device.
15. The assembly of claim 14, wherein the actuator arm is positioned so as to interact with the projecting arm of the cover, in the first position, so as to open the cover.

17. The assembly of claim 16, further comprising an inflate lever, that is configured to be depressed so as to urge the actuator arm to interact with cover.
18. The assembly of claim 17, further comprising a power switch, positioned with respect to the inflate lever so as to be contacted by the inflate lever when depressed, that biases on the fluid moving device to provide the fluid when contacted by the inflate lever, and that otherwise biases off the fluid moving device.
19. The assembly of claim 16, further comprising a deflate lever, that is configured to be depressed so as to interact with an open the cover and so as to interact with a portion of the diaphragm assembly so as to urge the at least the portion of the diaphragm at least partially away from the valve seat so as to open the self-sealing valve.
