Abstract: A pump cassette includes a cassette housing defining an input aperture configured to receive a surgical solution and an output aperture configured to expel the surgical solution. A flow path is defined between the input aperture and the output aperture and includes a sensor segment having a sensor segment input opening, a sensor segment output opening, and a pressure module configured to react to changes in pressure. A sensor segment wall defines a portion of the flow path between the sensor segment input opening and the sensor segment output opening. The sensor segment wall includes a first sensor segment wall portion located between the sensor segment input opening and the sensor segment output opening and a second sensor wall portion extending transversely from the first sensor segment wall portion to a sensor segment wall terminal end.

Abstract: A brewing apparatus including a housing having a movable lid; a water heater connected to the housing; and a hot water discharge head connected to the lid for delivering hot water from the hot water heater in a downward direction. The hot water discharge head includes at least two arrays of water discharge holes including a first center array of smaller holes and a second surrounding array of larger holes.

Abstract: A brewing apparatus, such as a coffeemaker, including a hot water heater; a first temperature sensor connected to the hot water heater; a second temperature sensor connected to either a cold water inlet to the heater or a hot water outlet from the heater; a pump connected to the cold water inlet for supplying water to the heater; and a controller coupled to the pump and the sensors. The pump is a variable speed pump. The controller is adapted to adjust the speed of the pump based upon signals from the sensors.

Abstract: A brewing apparatus including a housing having a movable lid and a brewing area under the lid; a hot water heater connected to the housing; a water pump connected to the hot water heater; a controller coupled to the hot water heater and the pump; and a switch connected to the housing and adapted to be actuated by a user movable member. The switch is coupled to the controller. The controller is adapted to discontinue heating by the heater when the switch is moved to a deactuated position.

Abstract: A brewing apparatus including a housing having a movable lid; a water heater connected to the housing; a pod carrier removably connected to the housing; a seal connected to the lid for movement towards and away from a top side of the pod carrier as the lid is moved between an open position and a closed position; and a hot water discharge head connected to the lid for delivering hot water from the water heater in a direction towards the top side of the pod carrier when the lid is in its closed position. When the lid is in its closed position, the movable lid closes over the top side of the pod carrier and, the seal is adapted to be located against a perimeter side of the pod carrier for sealing along the perimeter side.

Abstract: A brewing apparatus pod carrier including a frame forming a pod receiving cavity on a first side of the frame, a frothing chamber located below the pod receiving cavity, a brewed liquid outlet from the frothing chamber, and a connection section at a bottom end of the frame which is sized and shaped to have a frothing attachment removably connected thereto and supported by suspension from the bottom end of the frame.

Abstract: A brewing apparatus pod carrier including a frame forming a first pod receiving cavity on a first side of the frame and a second pod receiving cavity on a second opposite side of the frame, and a liquid flow path between the first and second pod receiving cavities. The first and second pod receiving cavities comprise different sizes.
