Abstract: A sample collection device includes a planar sheet of material having opposing edges and a first major surface and an opposing second major surface, the planar sheet of material having at least two fold lines. A porous sample collection media has at least three edges and opposing major surfaces, at least one edge is fixed to the first major surface of the planar sheet of material. The planar sheet of material is configured to form an airflow channel by fixing the opposing edges together, the airflow channel extends from a mouthpiece end to an air outlet end. The porous sample collection media substantially occludes the airflow channel between the mouthpiece end and the air outlet end.

Abstract: A multilayer optical film including a first layer having an index of refraction n1 at a wavelength λ in a range from about 580 nm to about 650 nm, and a second layer having an index of refraction n2 at λ is described. The first and second layers define an interface therebetween comprising a two-dimensional grating. The grating may have an average height H such that |n1−n2|*H is in a range from 0.24 micrometers to 0.3 micrometers. Optical systems including the multilayer optical film are described. A subpixel in a display surface of the optical system may be diffracted into a zero diffraction order and a plurality of first diffraction orders where the intensities of the zero and first diffraction orders are with 10% of each other at λ. The optical system may have a modulation transfer function greater than 0.4 at 10 line pairs per millimeter.

Abstract: A multilayer optical adhesive including a first viscoelastic or elastomeric adhesive layer and a second viscoelastic or elastomeric adhesive layer. A crosslinked or soluble resin layer may be disposed between the first viscoelastic or elastomeric adhesive layer and the second viscoelastic or elastomeric adhesive layer or the first viscoelastic or elastomeric adhesive layer may be immediately adjacent to the second viscoelastic or elastomeric adhesive layer. An interface between immediately adjacent layers is structured and there is a difference in refractive indices across the interface.

Abstract: A structured optical surface and an optical imaging system including the structured optical surface is described. The structured optical surface includes a plurality of structures formed by an intersection of at least first and second Fresnel patterns, such that when the structured optical surface is incorporated in an optical imaging system comprising a pixelated display surface with at least one pixel comprising at least two sub-pixels spaced apart by a gap, the structured optical surface images the at least two sub-pixels onto an image surface as at least two corresponding imaged sub-pixels spaced apart by a corresponding imaged gap, and the structured optical surface diffracts light so that the diffracted light at least partially fills the imaged gap without substantially overlapping any of the at least two imaged sub-pixels.
