Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Abstract: Various embodiments disclosed relate to an abrasive sheet. The abrasive sheet includes a first layer including an abrasive major surface and an opposite second layer defining a second major surface. The second major surface includes a plurality of protrusions extending outwardly from the second major surface. The protrusions include a first polymer component having at least one of a Shore A hardness ranging from about 5 to about 100 and a Shore D hardness ranging from about 1 to about 70. The first layer and the second layer are directly joined to each other.

Abstract: Various embodiments disclosed relate to an article. The article includes a first layer defining a first major surface of the article. The first layer includes a plurality of protrusions extending outwardly from the first major surface. The protrusions comprise an elastic polymer component. The article further includes a second layer opposite the first layer, which at least partially defines a second major surface of the article. The first layer is disposed over a range of about 5% surface area of the second layer to about 99% surface area of the second layer. The first layer and the second layer are in direct contact.

IPC: G02B5/136
Abstract: A retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected. For a second wavelength, light incident on the light control film at the first, but not the second, angle of incidence is retroreflected.

Abstract: Force-sensing capacitor elements and deformable membranes useful in electronic devices that include touch screen displays or other touch sensors. The deformable membranes, generally, include a first, second, and third layers with a first arrangement of a plurality of first structures interposed between the first and third layers and a second arrangement of one or more second structures interposed between the second and third layers. Electrodes may be included proximate to or in contact with one or more of the major surfaces of the first, second, and third layers or embedded within one or more of the second and third layers of the deformable membranes, yielding force-sensing capacitor elements. The electrodes proximate to or in contact with the one or more of the major surfaces of the first and second layers or embedded within one or more of the second and third layers may be one or more plurality of electrodes.

CPC classification number: B08B17/065 , A61B7/02
Abstract: Medical diagnostic devices or components thereof are described that comprise a microstructured surface that comprises peak structures and adjacent valleys wherein the valleys have a maximum width ranging from 1 to 1000 microns and the peak structures. In some embodiments (e.g.
for improved cleanability) the peak structures of the microstructured surface have a side wall angle of greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-comers elements. The microstructured surface of the medical diagnostic device typically comes in contact with multiple patients during normal use of the device, such as a stethoscope diaphragm. The microstructured surface exhibits better microorganism (e.g. bacteria) removal when cleaned and/or provides a reduction in microbial touch transfer. Also described are methods of making and methods of use.-

Abstract: A light control film is disclosed that includes a plurality of spaced apart first regions. Each first region has a substantially low transmission in one or two of a first wavelength range from about 300 nm to about 400 nm, a second wavelength range from about 400 nm to about 700 nm, and a third wavelength range from about 700 nm to about 1200 nm, and a substantially high transmission in the remaining wavelength ranges. The light control film has a viewing angle of less than about 70 degrees along a predetermined first direction.
