Embodiment Construction

[0017] A pump may fill inflatable objects with air or gas. The pump, which may include one or more electromechanical pumps, may interface circuits that route a portion of a current to a power source while delivering another portion of the current to a fluid displacement device. By sharing current with the fluid displacement device, the pump may compress or transfer fluids during a recharging process.

[0018]FIG. 1 is a perspective view of an inflatable object 100. The inflatable object 100 may comprise an inflatable mattress 102. Any inflatable object may be used, including objects and devices designed to be filled with air, gas, or fluids before use. The inflatable mattress 102 may include a top wall 104, a bottom wall 103, and a side gusset 106. A portable pump may be coupled to the inflatable mattress 102 at a valve 108 to receive a fluid or gas.

[0019]FIG. 2 is a diagram of a pump 200 coupled to charging circuitry. The pump 200 may interface a circuit 202 that includes a first po...

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

Description

BACKGROUND OF THE INVENTION [0001] 1. Technical Field [0002] This application relates to pumps, and more particularly to a portable pump that may be controlled by multiple power sources. [0003] 2. Related Art [0004] Portable pumps may be used to inflate objects. Some pumps may be powered by rechargeable batteries. After the batteries discharge, the pump may be connected to an external power source to recharge the batteries. The charging period may last for an extended period of time, during which the pump is inoperable. [0005] Some pumps resolve this problem by providing a connection to an external power source that recharges the batteries in a shorter time period. While these pumps reduce charging time, the pump remains inoperable during the recharging period. [0006] Therefore, there is a need for a portable pump that operates during a recharging process. SUMMARY [0007] A pump uses a power source to deliver power to a second power source while driving a fluid displacement device. T...
