Abstract: A beverage maker may comprise a heating system, a temperature sensor operably coupled the heating system, and a controller. The controller may be configured to receive a series of measured temperature signals from the temperature sensor, calculate a change in temperature using the series of measured temperature signals, and calculate an efficiency of the heating system based on the change in temperature. The controller may further estimate a scale buildup based on the efficiency of the heating system, and store at least one of the estimated scale buildup or the efficiency of the heating system in a heating system performance database.

The vent valve flow fuse includes a poppet configured to at least partially fit within the valve cap cavity and the valve body cavity. The vent valve flow fuse includes a spring configured to fit within the valve body cavity and to generate a resistive force against the poppet. The poppet is in a first position when fluid having a first amount of fluid pressure enters the valve cap cavity from a vent valve and engages the poppet. The poppet is in a second position when fluid having a second amount of fluid pressure enters the valve cap cavity and engages the poppet.

The heater core can include a core cavity configured to receive a heater therein to heat the heater core.

Abstract: A brew head assembly insertable within a brewing apparatus dimensioned to fit within a compartment in a galley of an aircraft may include an adjustable assembly and a brew cup. The adjustable assembly may include a brew head and a support member. The support member may define a first brew head cavity. The brew head may be at least partially inserted into the first brew head cavity. The adjustable assembly may be actuatable between an open position and at least one closed position. The brew cup may define a second brew head cavity. The brew head may be at least partially inserted into the second brew head cavity. A height between the brew head and the brew cup when the adjustable assembly is in the at least one closed position may be responsive to one or more parameters of a brew pod of a plurality of brew pods.

Abstract: An adjustable brew head linkage includes a brew head linkage element, a handle linkage element, and an adjusting element between the brew head linkage element and the handle linkage element to smoothly increase and decrease the distance between the brew head linkage element and the handle linkage element to alter the size of a corresponding brew chamber to accommodate various brew pods. The brew head linkage element and/or handle linkage element may include a threaded portion to engage the adjusting element. Turning the adjusting element causes deflection. Threaded portions may have opposite handedness or different pitches. A secondary brew head linkage locking element provides friction to lock the adjusting element in place. The adjusting element increases and decreases the distance between the head linkage and the handle linkage in increments smaller than 0.178 millimeters ( 7/1000 inches).

Abstract: A descaling module is disclosed. In one or more embodiments, the descaling module includes a container configured to receive a descaling fluid. The descaling module further includes at least one input port and at least one output port. The input port is configured to couple the container to a respective brew head of the beverage maker. The output port is configured to flow the descaling fluid through a fluid path of the beverage maker when pressurized fluid enters the container through the input port and forces the descaling fluid through the output port.

Abstract: A multi-position shuttle valve assembly includes a housing with at least one flow path and a shuttle. The at least one flow path is configured to receive steam from a froth heater of an aircraft brewing apparatus. The at least one flow path is configured to direct the steam to the defined cavity. The shuttle is configured to divert the steam to a froth wand when the shuttle is in a first position. The shuttle is configured to divert the steam to a froth module installed on the housing when the shuttle is in a second position. A translation of the shuttle between the first position and the second position is dependent on the froth module being installed on the housing.
