Beverage dispensing

This invention is a smart drink dispenser designed to pour carbonated beverages without creating excessive foam. It uses a computer inside to control the flow of the drink through a tube, based on what the user selects on a screen. The computer adjusts the flow to keep the liquid moving smoothly, preventing turbulence that causes bubbles, specifically by restricting the flow or actively pushing the liquid.

Why it matters: Microcontrollers and fluid sensors have become significantly more powerful and cost-effective since 2014, making sophisticated real-time flow compensation more feasible. This could enable more precise and cheaper anti-foaming control.
