SYSTEM FOR COMMUNICATION INFORMATION ENCODED IN A LIGHT-BASED SIGNAL USING A FOB DEVICE

摘要

A system, method, and apparatus for communicating information in a light-based signal utilizing a fob device (40) is disclosed. One method disclosed includes encoding transmission information data into a bar code format (10); generating a signal from the bar code format (10) to simulate a reflection of a scanning beam being moved across a static visual image of the bar code format (10); and actively transmitting the signal as light pulses from the fob device (40, 80). Alternatively, commercial information data may be transmitted to a light-based data receiving device by generating a signal from commercial information data and actively transmitting the signal as light pulses from a fob device (40, 80). Transmission information data may also be transmitted from a fob device (40, 80) by generating a first signal from a first encoded format; generating a second signal from a second encoded format; transmitting the first signal as light pulses from a fob device (40, 80); and transmitting the second signal from the fob device (40, 80).
