Claim of US Patent No. 9,384,495

1. A method of one-way communication transmission, comprising:
sensing, by an ambient light sensor embedded in a mobile phone, a light event;
determining, by the mobile phone, that the light event is a modulated light signal;
in response to the determination that the light event is the modulated light signal, parsing, by the mobile phone, an output
of the ambient light sensor including the modulated light signal to extract a uniform resource locator (URL) or a uniform
resource identifier (URI);

extracting, by the mobile phone, the URL or the URI from the modulated light signal based on the parsing;
displaying, by the mobile phone, in response to the extracting, at least one benefit accessed based on the URL or the URI
from at least one vendor of a plurality of vendors;

subsequent to parsing the output of the ambient light sensor and extracting the URL or the URI, averaging, by the mobile phone,
remaining raw sensor data of the output produced by the ambient light sensor; and

adapting a display brightness of the mobile phone based on the averaged raw sensor data.
