Abstract: A shower or tub assembly comprising a shower base or bathtub having a floor comprising an upper surface and a lower surface; and a support structure coupled to the floor lower surface, wherein when the shower or tub is in use, the floor upper surface is exposed and configured for a person to sit or stand on, and the lower surface is at least partially concealed, the support structure comprises a plurality of ribs, the ribs being substantially perpendicular to the floor, and the plurality of ribs at least partially form a repeating hexagonal pattern or at least partially form a repeating triangular pattern.

Abstract: An apparatus is used for determining at least one parameter relating to an elongate member disposed within a vessel. The apparatus includes at least one measurement unit having a light emitting component and a corresponding light receiving component. The light receiving component is positioned apart from the light emitting component such that the elongate member is positionable between the light emitting component and the light receiving component. Additionally, the light emitting component is adapted to emit light towards the light receiving component, and the light receiving component is adapted to generate a signal corresponding to the light received from the light emitting component. A method for determining at least one parameter relating to the elongate member disposed within the vessel is also provided.

Abstract: An apparatus for holding a contact lens during in vitro testing includes a first support member, a second support member, an alignment rod, and a cage member. The first support member includes a first end cap and a body portion. The body portion includes grooves formed in a lateral surface extending from the first end cap. The alignment rod is configured for interconnecting the body portion and a second end cap of the second support member. The cage member is positionable about the body portion between the first and second end caps, and includes an inner surface, an outer surface, and a plurality of openings between the inner surface and the outer surface. The inner surface and the lateral surface cooperatively define an annular space therebetween and a plurality of fluid flow paths between the inner space and the openings. The annular space is configured for receiving the contact lens.
