Synchronization and Processing of Secure Information Via Optically Transmitted Data
First Claim
1. A method of wireless data communication via an electronic device, said method comprising:
- providing a data transfer interface on the electronic device, wherein the data transfer interface supports processing of selected data by a processor of the electronic device that is functionally connected to an illumination light source, which light source is selectively utilized for illuminating a component in the electronic device and for transmitting data via optical pulses;
switching the illumination light source from an illumination mode to a data communication mode; and
transmitting a data stream from the electronic device by encoding the data in optical pulses from said illumination light source.

Abstract
A method and device enables data communication via optical pulses from a light source of an electronic device. A data transfer interface is provided to support processing of selected data by a processor of the electronic device. The electronic device comprises an illumination light source, which is selectively utilized for illuminating a component in the electronic device and for transmitting data via optical pulses. An optical receiver also receives optically transmitted data. The transmission and receiving of the data is provided on a bidirectional duplex communication link created with a second optical receiver and an optical data transmission mechanism of a second electronic device.
