Non-flickering illumination based communication

A process for simultaneously providing illumination which is free to the eye of flicker and other distracting optical phenomena and for providing communication comprising:

• providing a source of data comprising elements selected from a group consisting of analog data, digital data, control codes and start codes;
• providing an illumination means;
• analyzing the nature of the data from the source of data and the design of the illumination means, to determine if the nature of the data and the design of the illumination means can create flicker visible to the eye or other distracting optical phenomena in the output of the illumination means;
• based on the analysis, selecting an encoding means for the data such that it can be transmitted by modulating the illumination means without creating flicker or other distracting optical phenomena which are visible to the eye;
• providing a medium means through which the illumination passes;
• providing a receiver means for receiving and processing the modulated illumination from the illumination means and extracting the encoded data;
• providing a user means for using the data processed by the receiver means;
• transmitting data from the source of data to the illumination means which illumination means then transmits the encoded data by modulating the illumination means without creating flicker or other distracting optical phenomena which are visible to the eye to the receiver means which receives and processes the modulated illumination, extracts the encoded data and supplies it to the user means.

A network for simultaneously providing illumination free from flicker or other distracting optical phenomena to the eye and transmitting information comprising:

• a source of data with data elements selected from a group consisting of analog data, digital data, control codes and start codes;
• an illumination means in which the illumination means can be modulated and emit illumination;
• an encoding means for encoding the data for transmission by the illumination means;
• a medium means through which the illumination passes;
• a receiver means for decoding the data encoded in the illumination;
• a means for analyzing the nature of the data from the source of the data and the design of the illumination means, to determine if the nature of the data and the design of the illumination means can create flicker visible to the eye or other distracting optical phenomena in the output of the illumination means;
• and
• a user means for making use of the data decoded by the receiver means in which the encoding means is selected so that, for the data which will be transmitted and the illumination means which will be used, there will be no flicker or other distracting optical phenomena to the eye in the illumination.
