Automatic body spray system

A booth for automatic spray application of multiple liquids onto a human subject, the booth comprising:

• an HVLP nozzle including a nozzle tip;
• an air pathway that exits at the nozzle tip;
• a plurality of liquid sources, including at least a first liquid source having a first liquid and a second liquid source having a second liquid;
• a plurality of liquid lines connecting the plurality of liquid sources to a common liquid pathway that exits at the nozzle tip, the plurality of liquid lines including a first liquid line connected to the first liquid source and a second liquid line connected to the second liquid source;
• a plurality of check valves, each check valve being associated with a liquid line to prevent cross contamination between the first liquid and the second liquid;
• and
• a controller configured to cause air to flow through the air pathway, where the controller is further configured to cause the first liquid to flow from the first liquid source, through the first liquid line, through the common liquid pathway, and through the HVLP nozzle, and where the controller is further configured to cause the second liquid to flow from the second liquid source, through the second liquid line, through the common liquid pathway, and through the HVLP nozzle.

A booth configured to apply one or more liquids onto a human subject, the booth comprising:

• an HVLP nozzle system including a nozzle tip, the HVLP nozzle system being configured to move along a predetermined nozzle path;
• an air pathway that exits at the nozzle tip;
• multiple liquid paths that merge to a common liquid pathway, where the common liquid pathway exits at the nozzle tip;
• means for eliminating cross contamination between a first liquid associated with a first liquid source and a second liquid associated with a second liquid source;
• and
• a controller, where the controller is configured to cause the HVLP nozzle system to move along the predetermined nozzle path, where the controller is further configured to control an air source for causing air to flow through the air pathway, and where the controller is further configured to control a first flow of liquid from the first liquid source and a second flow of liquid from the second liquid source.
