Abstract: A chilled liquid dispensing system includes a vessel with phase change material that can be charged by a thermoelectric module via a first heat sink. A liquid (e.g., beverage) can be pumped through a conduit submerged in the phase change material to cool or chill the liquid to a temperature below ambient temperature. The liquid can be infused with a gas (e.g., nitrogen, air) to provide foam and enhance the flavor of the liquid. The chilled liquid dispensing system can be incorporated into a liquid dispensing machine (e.g., beverage dispensing machine).

Abstract: Systems and methods that facilitate a multi-color error code recognition system. In a one embodiment, the device includes a micro processor based control system and one or more LED indicators coupled to the control system and capable of emitting two or more colors of light. In operations, the control system detects a failed mechanism in the device and causes the one or more LED indicators to blink in a first color a number of times corresponding to the first digit of the error code and then blink in a second color a number of times corresponding to the second digit of the error code.
