Patent ID: 7058484

Claim:
A system for configuring an output of a configurable power supply, comprising: interfacing means for electrically coupling said power supply to independently and simultaneously access both a previously unknown battery-powered device and an installed battery thereof, said coupling resulting in the power supply being capable of bypassing said battery as a source of power for the powered device, without limiting said battery's ability to automatically access said device; preloading means for temporarily electrically coupling to the battery at least one of one or more substantial resistive loads, said resistive loads being capable of combining in order to vary the coupled load; processing means accessible to said power supply for executing program instructions embodied on a computer-readable medium, comprising: detecting means for acquiring at least one value as to voltage sag resulting from said preloading; analyzing means for evaluating the acquired voltage-sag value and determining an anticipated fully-charged battery voltage; said analyzing means further for producing an output voltage value of the configurable power supply by performing in a work space at least one of one or more predetermined computations based on acquired and memorized voltage values, and controlling means accessible to said processing means and power supply for configuring the output voltage of the power supply to said previously produced output voltage value, whereby, said power supply delivers a suitably configured power signal to said device.
