Abstract

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

Claims

exact text as granted — not AI-modified
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.
