Opportunistic power supply charge system for portable unit
First Claim
1. A portable computing device, comprising:
- a component that receives an electro-magnetic flux generated from an external source; and
a charging component that generates a charging current from the flux, and charges a rechargeable power supply; and
a controller that determines a first charging time for the portable computing device and allocates a second charging time to the portable computing device.

Abstract
Systems and methods for opportunistically charging a rechargeable power source of a portable electronic unit are provided. The system includes a primary inductance assembly energized by a main power source for inducing an electro-magnetic flux in a secondary coil assembly associated with a power source of the portable unit. Such electro-magnetic flux creates an electric current that is subsequently employed for charging the power source of the portable unit. A controller of the charging system can monitor state of charge, and notify a user when a recharge is required. Scavenging modes may also be employed for recharging the main power source and the rechargeable source of the portable unit.
