Abstract: The present disclosure provides a display system. The display system includes a backlight configured to emit substantially collimated polarized light from an emission surface thereof. The emitted polarized light is polarized along a polarization direction. The display system further includes a display panel configured to receive an illumination light and form an image. The display system further includes a grating system substantially coextensive in length and width with the display panel and the emission surface. The grating system includes a plurality of substantially parallel elongated features extending along an in-plane first direction and arranged along an orthogonal in-plane second direction. The grating system is configured to receive and transmit an incident polarized light as a first transmitted light having different first and second polarization states in response to different respective first and second signals applied to the grating system.

Abstract: A display system includes a display configured to emit an image for viewing by a viewer. The display system further includes one or more phase lens layers disposed on, and substantially co-extensive in length and width with the display. Each of the one or more phase lens layers is configured to have different first and second focal lengths for different respective first and second polarization states. The display system further includes a first polarization modifying layer disposed between the display and the one or more phase lens layers. The first polarization modifying layer is configured to receive the emitted image and transmit a transmitted image. The transmitted image has the first and second polarization states in response to different respective first and second signals applied to the first polarization modifying layer.

Abstract: A light control film is described comprising a light input surface and alight output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions comprise light-absorbing or light-reflecting particles and a dried aqueous dispersion of an organic polymer. The light control film can have improved on-axis transmission in combination with sufficiently high sheet resistance such that the film does not detract from the responsiveness of a touch screen of an electronic device. Also described is a coated article and method of making.

Abstract: A composite article having a conductive layer on at least a portion of a flexible substrate. Electrical connectivity between various portions of the substrate can be obtained through this conductive layer. The conductive layer comprises a conductive surface, and there is a patterned layer on at least a portion of a first region of the conductive surface. The patterned layer comprises a conductive material having a surface roughness, and is in electrical contact with the conductive surface. An overcoat layer is present on at least a portion of the first region, such that the overcoat layer has a thickness less than the surface roughness, such that the conductive layer within the first region is covered by the overcoat layer, and such that at least a portion of the patterned layer substantially protrudes above the overcoat layer.

Abstract: A vehicle cooling system is provided having a heat exchanger, a cooling fan, and a fan shroud. The vehicle cooling system has a variable cooling fan immersion system that uses a control system and a variable cooling fan immersion depth adjustment mechanism to control the percentage of cooling fan immersion into the space enclosed by the fan shroud. The variable cooling fan immersion system is used to maximize the efficiency of a variable pitch cooling fan, a variable speed cooling fan drive, or both.

Abstract: A diesel exhaust fluid (DEF) delivery system includes a tank for DEF, usually a urea aqueous solution, and a pump receiving the DEF from the tank for pressurization and delivery through a nozzle to the exhaust system of a work machine. A breather assembly is provided for the DEF tank and includes a housing having an inlet for ambient air and a particle filter adjacent the inlet for filtering particles. A hydrophobic membrane is interposed between the particle filter and an outlet leading to the tank for preventing outflow of DEF vapor and condensate.

Abstract: A cutting assembly for a header of a plant-cutting machine includes a blade assembly fastened to a head assembly, which is configured to be drivingly connected to a motor. The cutting assembly is suitable for mounting proximate to the center of the header, in an end-to-end relation with another cutting assembly. Removal of the blade assembly from the head assembly can be efficiently effected by releasing or removing a small number of fasteners, thus allowing an operator to readily remove or replace the blade assembly as needed.
