Illumination-Based Charging System for Portable Devices
First Claim
1. A system for charging one or more portable devices, comprising:
- a platform configured to support one or more portable devices;
a plurality of photosensitive detectors;
a plurality of illumination sources; and
a controller in communication with the plurality of photosensitive detectors and the plurality of illumination sources;
the controller being configured to;
activate the plurality of illumination sources to illuminate a surface of a portable device supported by the platform,determine a set of one or more illumination sources from the plurality of illumination sources being at least partially overlaid by the portable device based upon reflected illumination received by the plurality of photosensitive detectors from the illuminated surface of the portable device, andactivate or maintain activity of a selection of one or more illumination sources from the plurality of illumination sources to direct illumination towards at least a portion of the surface of the portable device, the active selection of one or more illumination sources being at least partially based upon the set of one or more illumination sources determined to be overlaid by the portable device.

Abstract
The disclosure is directed to illumination-based charging of one or more portable devices. According to an embodiment of the disclosure, an illumination-based charging pad includes a platform, a plurality of illumination sources, a plurality of photosensitive detectors, and a controller. The controller performs a scan by activating the illumination sources and detecting reflected illumination from an illuminated surface of at least one portable device disposed upon the platform. The controller determines a set of one or more illumination sources that are at least partially overlaid by the portable device based upon the detected illumination. The controller selects one or more illumination sources for charging the portable device at least partially based upon the set of one or more illumination sources determined to be overlaid by the portable device.
