Abstract: There is provided a method of measuring liquid volume in a sealed container of a breast pump of known volume comprising liquid and gas. The method includes a measurement phase, measuring the volume of gas in the container by changing a first parameter of the gas by a known amount. The method also includes measuring a change in a second parameter of the gas; calculating the volume of gas in the container using the measured change and a predetermined operation equation; and determining the volume of liquid in the container based on the calculation.

Abstract: An attachment including an air inlet for receiving airflow from a hair styling apparatus, at least one air outlet, a chamber for conveying air from the air inlet to said at least one air outlet, wherein the air inlet is located at one end of the chamber, and the at least one air outlet extends along the length of the chamber and the cross-sectional area of the chamber decreases in size from the air inlet along the length of the at least one air outlet.

Abstract: An attachment including a casing having an air inlet for receiving airflow from a hair styling apparatus, a hair engaging member supported by the casing, a first airflow outlet between the casing and the hair engaging member, a second airflow outlet, spaced from the first airflow outlet, between the casing and the hair engaging member and internal airflow directing means positioned within the casing to direct air towards the first airflow outlet and the second airflow outlet.

Abstract: An attachment for a hair care appliance includes an elongate body having a first end and a second end, a fluid inlet at the first end, a fluid outlet and a fluid flow path extending between the fluid inlet and the fluid outlet wherein the diameter at the first end is larger than the diameter at the second end and the fluid outlet extends from the first end to the second end. The elongate body may converge from the first end towards the second end. The elongate body may gradually reduce in diameter from the first end. The reduction in diameter may extend along a portion of the elongate body. There may be a gradual transition from the diameter at the first end to the diameter at the second end.

Abstract: An attachment for a hair care appliance includes a body having a fluid inlet, a fluid outlet, a fluid flow path extending between the inlet and outlet and at least one vane for directing fluid within the fluid flow path towards the fluid outlet, wherein the body includes at least two extended plates and the fluid outlet includes a slot defined by an overlap between the at least two extended plates, and wherein the at least one vane is positioned within the overlap between the at least two extended plates. The body may be elongate, may have a first end including the fluid inlet, and may extend along an axis. The fluid outlet may extend along the axis between the first end and a second end. The at least one vane may direct fluid flowing in the fluid flow path from a first direction to a second direction.

Abstract: An attachment including an air inlet for receiving airflow from a hair styling apparatus, an air outlet, a duct for conveying air from the air inlet to the air outlet, wherein the air inlet is located at one end of the duct, and the air outlet extends along the length of the duct and the cross-sectional area of the duct decreases in size from the air inlet along the length of the air outlet.

Abstract: An attachment including a duct having an air inlet for receiving an airflow from a hair styling apparatus, at least one vane located within the duct for directing the airflow towards an air outlet and the air outlet is elongate in shape and orientated generally parallel to the direction of airflow at the air inlet.

Abstract: An attachment includes a casing having an air inlet for receiving airflow from a hair styling apparatus, a hair engaging member supported by the casing, an airflow outlet between the casing and the hair engaging member and shaped to direct air over an external surface of the hair engaging member and airflow guiding means extending over the external surface of the hair engaging member.
