Abstract: Methods and systems of determining the amount of liquid in a liquid supply tank of a beverage forming machine without a dedicated sensor are disclosed herein. In some embodiments, the beverage forming machine includes a controller capable of determining the amount of liquid in the liquid supply tank based on a gas volume in a reference vessel, such as a conduit, in fluid communication with the liquid supply tank.

Abstract: Methods and systems for electrically powering liquid-contacting components of a beverage machine using a non-isolated power supply.

Abstract: Methods and systems for employing a sensor to detect disconnection of a liquid supply tank and a low fill level of the liquid supply tank are disclosed herein. The sensor may have a conductive probe to contact liquid, e.g., to detect a liquid level in a removable liquid supply tank.

Abstract: A beverage preparation machine having an inlet arrangement and a gasket arrangement is provided, where the inlet arrangement is configured with a plurality of inlet ports to deliver liquid to a beverage cartridge. The gasket arrangement may include a single unitary shape with a plurality of openings for receiving the plurality of inlet ports. The gasket arrangement may include one or more inner ribs disposed about each of the plurality of openings. A perimeter rib may extend along a perimeter of the gasket arrangement.

Abstract: Methods and systems for employing a sensor to detect two physical characteristics of a liquid in a beverage machine. A sensor may have a conductive probe portion to contact liquid, e.g., to detect a liquid level in a removable water tank, and a thermistor portion to detect a temperature of the liquid.

Abstract: Aspects relating to a method and apparatus for venting a heater tank of a beverage forming apparatus using a vent valve that is opened and closed based on an operation to move a brew chamber lid between an open lid position and a closed lid position are provided. In one aspect, the vent valve may be positioned on a vent line distinct from a delivery line that delivers heated liquid from the heater tank to the brew chamber. In another aspect, at least a portion of the delivery line may extend downwardly from the top of the heater tank to a location between the top and the bottom of the heater tank. In another aspect, the at least a portion of the vent valve may be attached to the handle for movement with the handle.

Abstract: A method and apparatus for venting a liquid supply of a beverage machine, e.g., by permanently open orifice and/or pressure relief valve. The orifice may always vent a heater tank, even while liquid is delivered to the tank by a liquid pump and/or while the tank is pressurized by an air pump to deliver liquid from the tank. A filter may be positioned between a heater tank and orifice and/or air pump. The pressure relief valve may be positioned between the liquid pump and the inlet side of the heater tank, e.g., so relatively cool water is released by the pressure relief valve when open.

Abstract: A reusable cartridge and method for forming a beverage using a beverage machine. The cartridge may include multiple openings, e.g., arranged to receive an inlet needle, through which liquid may be introduced into the cartridge. One or more of the openings may be closed to flow, e.g., by a plug that engages with a corresponding opening by a friction fit. A filter basket may be inserted or removed into the interior space through the opening and a cover may engage at top to seal the opening closed.

Abstract: An apparatus and method for sharing capsule image data and beverage preparation parameters, from one or more beverage preparation machines with a remote computer system via a network, such as the Internet, is disclosed. The remote computer system may process the capsule image data to determine characteristics of the capsule (e.g., a type of capsule, such as a brand, or beverage ingredients in the capsule), thereby relieving the beverage preparation from having to determine information about the capsule. The remote computer may track a user's consumption of capsules, may compare this value to the user's past capsule purchase history, and may determine if the user's supply of capsules is below a threshold value (e.g., below a week's worth of capsules).

Abstract: A method and apparatus for venting a liquid supply of a beverage machine, e.g., by permanently open orifice and/or pressure relief valve. The orifice may always vent a heater tank, even while liquid is delivered to the tank by a liquid pump and/or while the tank is pressurized by an air pump to deliver liquid from the tank. A filter may be positioned between a heater tank and orifice and/or air pump. The pressure relief valve may be positioned between the liquid pump and the inlet side of the heater tank, e.g., so relatively cool water is released by the pressure relief valve when open.

Abstract: A beverage cartridge and method for forming a beverage includes dispensing beverage material from a container into an attached mixing funnel. The container and mixing funnel may be moved toward each other to open the container and release beverage material. A cover of the container may have a movable portion that moves with contact with a part of the mixing funnel to open the container. The cartridge may be vibrated to dispense beverage material from the container, and liquid provided to the mixing funnel to mix with dispensed beverage material to form a beverage.

Abstract: A beverage dispenser includes a housing and a user interface disposed on a vertical corner of the housing. The user interface includes one or more buttons that are accessible from a front view and a side view of the housing.

Abstract: A beverage forming system having a controller arranged to adjust at least one of a set of brew parameters in response to a failure to identify a characteristic of a capsule to be used to form a beverage. An adjusted brew parameter may be a configuration-type parameter that is generally has a fixed value for all or most beverage dispensing operations, or a beverage-specific parameter that may be user-adjusted for each beverage dispensing operation.

Abstract: A beverage machine may have a first brew chamber for forming larger, multi-serving beverages, and a second brew chamber for receiving beverage cartridges to form single-serve beverages. Aspects relating to relative positioning of the brew chambers and associated components are described herein. The beverage machine may include a user interface that displays different selection options based on which of the two brew chambers is being used to form a beverage. The beverage machine may include a handle that may be manipulated by a user to both open a brew chamber and to remove a brew basket from the brew chamber. The beverage machine may include a liquid reservoir that removably couples to the machine housing at different discrete positions. The beverage machine may include a liquid supply lid that may be removably coupled to the housing.
