Abstract:
A method for producing and controlling an image defined by fluid bubbles in a medium fluid, comprising:separating a bubble fluid and said medium fluid within a fluids subsystem;forming said fluid bubbles from said bubble fluid within said medium fluid by utilizing a plurality of bubble generators in a bubble generation subsystem;maintaining separation of said medium fluid from said bubble fluid by providing a valve disposed above each of said bubble generators; and,controlling and timing a duration of operation of each said bubble generators and each of said valves, further comprising:mounting electronic circuits and support electronics on a microprocessor-based electronic control subsystem;providing control inputs to a user to set local time and operating features;utilizing software or hardware to translate graphics or alphanumeric digits into control signals that activate each of said bubble generators;assembling a plurality of stored digit values to produce a command sequence line, wherein said command sequence line controls a creation of one horizontal row of said fluid bubbles;activating a first set of said control signals to create said horizontal row; and,repeating said activation until a full vertical length of said graphic or said alphanumeric digit is reached.
