Disclosed herein is an article that includes a first plurality of spaced features. The spaced features are arranged in a plurality of groupings; the groupings of features include repeat units; the spaced features within a grouping are spaced apart at an average distance of about 1 nanometer to about 500 micrometers; each feature having a surface that is substantially parallel to a surface on a neighboring feature; each feature being separated from its neighboring feature; the groupings of features being arranged with respect to one another so as to define a tortuous pathway. The plurality of spaced features provide the article with an engineered roughness index of about 5 to about 20.

Disclosed herein is a ventilator text fixture comprising a ventilator port that connects to a ventilator through a breathing circuit; where the ventilator delivers air through the ventilator port to a ventilator test fixture at a rate and pressure that can be controlled by a user to simulate inhalation; an input port; where the input port is in fluid communication with the ventilator port; where the input port permits additional simulated secretions or test liquids to be pumped into the ventilator text fixture; one or more bent supports; a liquid reservoir; where the liquid reservoir is operative to hold test fluids; and one or more tubes; where the one or more tubes are in fluid communication with the ventilator port and the input port via the liquid reservoir; and where the one or more bent supports are operative to mimic an anatomy of the trachea.

Generally, an intraocular implant having on the external surface a plurality of pattern surface elements disposed in spaced apart relation defining a tortuous pathway adapted to control a flow of fluid, or a flow of particles suspended in a fluid, or inhibits the growth or migration of cells. In particular, an intraocular implant which implanted between an intraocular lens and the surface of the posterior capsule of the eye inhibits growth or migration of residual lens epithelial cells after cataract surgery by providing structural barriers to reduce posterior capsule opacification of the eye.

The present disclosure generally relates to a formulation. More particularly, the formulation may be applied to skin and/or used in combination with a personal care product to improve absorbance and leakage control of the personal care product, and to promote a more positive feel and comfort through improved skin cleanliness and health.
Method of making, using and applying a composition to an exposed surface
Chantel Buhrow, Bernard Minerath, Chelsea M. Magin, 2005/12/8, US11/297,674 (link)
Methods of making, using and applying a composition to an exposed surface are disclosed using a disposable applicator. The method of making the disposable applicator includes forming a back sheet and a liquid permeable substrate. The substrate is secured to the back sheet and a composition is applied to the substrate. The composition is capable of being transferred onto an exposed surface by wiping the substrate against the exposed surface. A seal is formed on at least a portion of the back sheet. The back sheet is then folded upon itself such that the seal extends completely around the substrate to protect the composition. The methods of using and applying a composition to an exposed surface include breaking the seal and opening the back sheet, grasping the back sheet in one hand and wiping the substrate onto the exposed surface.

A disposable applicator is disclosed for applying a composition to an exposed surface. The applicator includes a back sheet, a liquid permeable substrate secured to one surface of the back sheet, and a composition applied to the liquid permeable substrate. The composition is capable of being transferred to an exposed surface by wiping the liquid permeable substrate against the exposed surface. The applicator also has a seal formed on at least a portion of an inner surface of the back sheet. The back sheet is then folded upon itself such that the seal extends completely around the perimeter of the substrate and protects the composition.
