Abstract: A light control layer includes alternating transmissive and absorptive regions, along one or two dimensions. The light control layer may be substantially transparent, or have high transmission, for light incident at or near a normal angle to its surface, while absorbing light incident at angles away from normal. The height of the absorptive region, defined orthogonal to the local display surface, may be much greater than the width of the absorptive region resulting in a high aspect ratio structure. The width of the absorptive region may be relatively thin compared to the width of a pixel in a display. The light control layer may be applied to a display or incorporated into a display. The light control layer may be part of a film stack including other functional layers that cooperatively provide desirable optical properties.

Abstract: A sample collection system includes a housing comprising a first part and a second part, the first and second parts being movable relative to one another; porous sample collection media disposed along an airflow path in the first part; and an assay disposed on the second part and constructed to receive a sample captured by the porous sample collection media. The first and second parts are rotatably movable relative to one another. Moving the first and second parts relative to one another aligns the porous sample collection media with at least a portion of the assay. The assay may be a lateral flow assay or a vertical flow assay. The media is constructed to collect a sample from exhalation airflow. A collected sample may be eluted from the media onto the assay using a liquid.

Abstract: A sample collection device includes a housing extending from a mouthpiece end to an air outlet end, the housing defining an airflow channel from the mouthpiece end to the air outlet end, the mouthpiece end configured to receive an exhalation airflow. A porous sample collection media is fixed within the housing and along the airflow channel. A mouthpiece end cap is replaceably coupled to the mouthpiece end and an air outlet end cap is replaceably coupled to the air outlet end.

Abstract: An optical construction includes a reflective polarizer and an optical film. The optical film includes a matrix and a plurality of first particles dispersed in the matrix. Each of the matrix and the plurality of first particles includes a silicone polyoxamide and an acrylate polymer. For substantially normally incident light and for at least a first wavelength in a first wavelength range, the reflective polarizer reflects about 60% for a first polarization state and transmits about 40% for an orthogonal second polarization state. For at least a second wavelength in a second wavelength range, each of the reflective polarizer and the optical film transmits about 60% of an incident light for each of the first and second polarization states. For at least the first wavelength, optical film has an optical haze and a depolarization ratio. A ratio of the depolarization ratio to the optical haze is less than 0.1.

Abstract: An optical film for reducing at least one of sparkle and moire in a display system includes a structured first major surface that, in at least a first cross-section in a first plane substantially orthogonal to the optical film, has a sinusoidal shape having a variable pitch of greater than about 0.5 microns. For a substantially normally incident light and blue, green, and red wavelengths that are at least 50 nm apart from each other and are disposed within respective blue, green, and red wavelength ranges, optical transmissions of the optical film versus transmitted angle for the blue, green and red wavelengths have respective blue, green, and red transmission bands disposed at angles greater than about 1 degree and having respective blue, green, and red full width at half maxima (FWHMs), at least two of which at least partially overlap.

Abstract: Curable compositions include at least one fluoropolymer, at least one monofunctional (meth)acrylate, at least one difunctional (meth)acrylate, and at least one initiator. The curable composition, when cured, forms an optically-scattering layer including a matrix and phase separated microdomains. The matrix and the phase separated microdomains have different refractive indices, and the microdomains are on the order of or larger than the wavelengths of visible light.
