A method and computer program product for defining a PWM drive signal having a defined voltage potential. The PWM drive signal has a plurality of “on” portions and a plurality of “off” portions that define a first duty cycle for regulating, at least in part, a flow rate of a pump assembly. At least a portion of the “on” portions of the PWM drive signal are pulse width modulated to define a second duty cycle for the at least a portion of the “on” portions of the PWM drive signal. The second duty cycle regulates, at least in part, the percentage of the defined voltage potential applied to the pump assembly.

A system includes a sensor and a computing system. The sensor is coupled to a syrup line of the beverage dispenser and is configured to measure a pressure within the line. The syrup line is coupled at a first end to a syrup bag and at a second end to a pump configured to pump syrup from the syrup bag to an outlet of the beverage dispenser. The pump is operated using pressurized gas and generates a pressure corresponding to the pressure of the gas within the syrup line when both the syrup bag is full and the outlet of the beverage dispenser is closed. The sensor transmits a measured pressure to the computing system. The computing system determines that the measured pressure is less than a threshold pressure. In response, the processor transmits an alert for display on a user device, which identifies the syrup bag for replacement.

A self-propelling container having: a top; a bottom; a plurality of vertical walls extending between the bottom and the top; an inner bag for holding contents to be dispensed; a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting the contents to or from the container after the friction seal is established between the female and male couplings; and at least one independent panel positioned inside the container; a compressible element associated with the at least one independent panel wherein during filling of the inner bag the compressible element is compressed, thus causing the at least one independent panel to exercise pressure onto the inner bag, and thus, helping to empty the inner bag.

Beverage dispensers are disclosed. A beverage dispenser may include a carbonation pump, pressure tank, and a pressure switch configured to active the pressure pump when a pressure in the pressure tank falls below a threshold pressure. The pressure switch may cause the carbonation pump to shut off when the pressure in the pressure tank exceeds an upper threshold pressure. The beverage dispenser may be convertible from a carbonated beverage dispenser to a non-carbonated beverage dispenser.

A contactless beverage dispenser, system, and method of contactlessly dispensing a beverage are disclosed herein. Embodiments of the present invention utilize a sensor that is operatively coupled to a pump for selective activation thereof. The sensor detects, in a sensor zone, the presence of a beverage container proximal a dispensing spout of the beverage dispenser. The sensor may be a proximity sensor, such as a photoelectric sensor. Upon detection of the beverage container, the pump is activated and dispenses a beverage to a user.

A beverage supplying device comprising: a touch panel for receiving an operation for selecting a main syrup constituting a main beverage, and a topping syrup added as flavoring to the main beverage; a second syrup solenoid valve for opening and closing a passage for supplying the topping syrup that is stored under pressure in a syrup tank; a second syrup pump for intermittently supplying the topping syrup while the second syrup solenoid valve is open, the second syrup pump being provided to the passage for supplying the topping syrup between the syrup tank and the second syrup solenoid valve; and a nozzle for producing the main beverage by mixing the main syrup with water or carbonated water at a prescribed ratio, and producing a beverage by mixing the topping syrup with the main beverage without diluting the topping syrup.

DEVICE FOR DISPENSING A GAS-CONTAINING LIQUID, WITH A VALVE FOR INTRODUCING CO2, which has been developed to provide a better use, way of serving and flow control for carbonated beverages, particularly, a flow control device to reduce the gas dissipation on the beverage, whether it is from the quantity remaining in the bottle or the drink to be served.

A portable hydration system and various components are disclosed. The system utilizes a pump to transfer potable liquid (e.g. water) from a liquid container to a user during challenging activities (e.g. endurance motorcycle riding).

A refrigerated beverage dispenser conversion system includes an electric pump configured for being mounted within an interior of a refrigerated beverage dispenser, the electric pump having an inlet and an outlet. An inlet barb is operatively connected to the electric pump at the inlet, and an inlet hose is operatively connected to the inlet barb at a first end of the inlet hose. The inlet barb and the inlet hose are sized to engage an outlet of a container disposed within the refrigerated beverage dispenser to bring the container in fluid communication with the electric pump. An outlet barb is operatively connected to the electric pump at the outlet and sized for operatively connecting to an outlet hose in fluid communication with an outlet of the refrigerated beverage dispenser. The outlet barb is differently sized from the inlet barb, such that the refrigerated beverage dispenser conversion system is configured to bring the container in fluid communication with the outlet of the refrigerated beverage dispenser.

A beverage dispenser includes a gas infusion device configured to infuse a gas into a base liquid to form a gas-infused liquid, a mixing chamber configured to mix the gas-infused liquid and a concentrate to thereby form a reconstituted beverage, a first flow control configured to decrease pressure of the gas-infused liquid prior to mixing with the concentrate, and a second flow control configured to decrease pressure of the concentrate prior to mixing with the gas-infused liquid. A restrictor device downstream from the mixing chamber and configured to apply backpressure on the concentrate and the gas-infused liquid, and a dispensing valve is configured to dispense the reconstituted beverage.
