Abstract: Barcodes stored by mobile devices can be used in commerce. In sending barcode data optically from a display backlight of a mobile communication device to a barcode scanner optical receiver, the transmitted data bit time needs to be compatible with the frequency range the barcode scanner is designed to receive. The disclosed methods and mobile devices can send barcode data optically at different frequencies from a modulated display backlight to different models/makes of laser barcode scanners that may be used at a point of sale (POS). The disclosed are methods and devices for processing the bit time mix choices make a determination of bit time mix choices based upon predetermined criteria. Location of the device is an example of predetermined criteria. A location may have a particular bit time mix signature that may be accessed, for example, in a look up table.

Abstract: An electronic device includes a data processor and data communication mechanism for: (a) transmitting, via an optical link, configuration and authentication requests/information for a second data communication link to an external device; and (b) transmitting other content data via the separate, second data communication link that is configured using the configuration data transmitted on the optical link. Data communication on the optical link is provided via modulated optical pulses from an illumination light source of the electronic device. The light source is selectively utilized for illuminating a component in the electronic device and for transmitting configuration/authentication data via optical pulses. An optical receiver also receives optically transmitted configuration/acknowledgement data from the external device.

Abstract: An electronic device 100 includes a data processor 106 for generating a data stream for communication with an external device. The electronic device also includes an illumination light source (145) for illuminating components (140) within the electronic device 100 and which provides modulated optical signals indicative of the data stream generated from the data processor 106. A power management circuit 150 is operatively connected to the data processor 106 and to the illumination light source (145). The power management circuit 106 selectively drives the illumination light source (145) with power levels optimized for illuminating the components (140) or with power level modulation indicative of the data stream generated from the data processor 106. The electronic device 100 also includes an optical receiver 170 by which the electronic device 100 receives modulated optical signals containing a data stream generated from another device.
