Rechargeable AC/DC pump
A pump uses a power source to deliver power to a second power source while driving a fluid displacement device. The pump includes a fluid displacement device and a circuit coupled to a first power source and a second power source. The first power source may draw a first current from the second power source. The second power source supplies power to the fluid displacement device
1 . A pump, comprising:
a fluid displacement device; and
a circuit coupled to the fluid displacement device that drives the fluid displacement device;
where the circuit routes a first current to a first power source, while a second current from the second power source is routed to drive the fluid displacement device.
2 . The pump of claim 1 , where the fluid displacement device is driven at a substantially synchronous rate.
3 . The pump of claim 2 , where the first current comprises a portion of current from the second power source.
4 . The pump of claim 3 , where the circuit is configured to be coupled to an alternating current and a direct current source.
5 . The pump of claim 4 , further comprising a converter that transforms the alternating current source into a direct current.
6 . The pump of claim 5 , where the second power source comprises an alternating current source.
7 . The pump of claim 5 , where the second power source comprises a direct current source.
8 . The pump of claim 5 , where the first power source and the second power source comprise a direct current source.
9 . The pump of claim 5 , further comprising a controller to break a current path.
10 . The pump of claim 9 , further comprising a device coupled to the first power source that substantially restricts a third current flow in one direction.
11 . The pump of claim 10 , where the pump inflates an inflatable object.
12 . A pump, comprising:
a fluid displacement device; and
a circuit coupled to the fluid displacement device that drives the fluid displacement device;
where the circuit is configured to receive a first power source or a second power source to route a first current to a third power source, while routing a second current to drive the fluid displacement device.
13 . The pump of claim 12 , where the third power source comprises a direct current source.
14 . The pump of claim 13 , where the first power source comprises an alternating current source.
15 . The pump of claim 14 , where the first current comprise a portion of current from the first power source.
16 . The pump of claim 15 , where the second power source comprises a direct current source.
17 . The pump of claim 16 , where the first current comprises a portion of current from the second power source.
18 . A method of driving a pump, comprising
providing a fluid displacement device;
providing a circuit coupled to the fluid displacement device, the circuit comprising a first power source;
coupling a second power source to the circuit;
routing a first current to the first power source while routing a second current to the fluid displacement device.
19 . The method of claim 18 , where the first current comprises a portion of current from the second power source.
20 . The method of claim 19 , where second power source comprises an alternating current source.
21 . The method of claim 19 , where the second power source comprises a direct current source.
22 . The method of claim 19 , where the first power source and the second power source comprise a direct current source.
23 . The method of claim 19 , further comprising the step of coupling a controller to the pump to break a current path.
24 . A pump, comprising:
means for displacing a fluid; and
means for routing a first current to a first power source while routing a second current from a second power source to the fluid displacement means.
25 . A pump, comprising:
means for displacing a fluid; and
means for routing a first current to a third power source while routing a second current from a first or second power source to the fluid displacement means.
