摘要:
A communication article and system comprising a writing member having a dry erasable front surface and a projection member is disclosed. The projection member includes an asymmetric optical diffuser that scatters light in a first direction with a first viewing angle AH, and in a second direction orthogonal to the first direction with a second viewing angle AV. The ratio AH/AV is at least about 2.
摘要:
Articles with rewritable writing surfaces thereon comprising a coating of hydrophilic silane or a hydrophilic water soluble polymer with hydroxyl groups which is crosslinked or chemically reacted to the surface. Also, methods for making such articles and methods for using such articles.
摘要:
Assemblies containing a substrate with pockets for electromagnetically responsive particles can be made for a variety of uses, including, for example, display media, lenses, and color-changing fabric. The arrangement of these pockets can be selected to provide higher particle density than previously realized. The assembly includes an assembly substrate, particles, and a top coat layer.
摘要:
A sheet dispenser including a housing, and a stack of dispensable sheets. A front wall of housing has edges that define a slot through which an end portion of the top sheet on the stack projects. That front wall normally projects above the top surface of the stack of sheets to position that end portion of the top sheet in a position projecting above an outer surface of the front wall where it can be easily grasped to withdraw the top sheet from the housing. At least a portion of the front wall is of flexible material so that it can be resiliently bent to lie along the top surface of the stack and thereby reduce the thickness of the dispenser when, for example, it is positioned on one of the pages of a book, magazine, personal organizer or the like that is closed.
摘要:
A frame assembly for use on a device such a computer monitor having a front viewed surface surrounded by a housing. The frame assembly includes a stiff frame having generally planar front and rear surfaces that includes elongate border portions having inner edge surfaces that define an opening through the frame corresponding in shape to the front viewed surface. The rear surface of the frame can be attached along the front surface of the housing with the opening in the frame aligned with the front viewed surface, and a layer of repositionable pressure sensitive adhesive adhered to the frame is accessible along the front surface of the frame so that sheets of paper and other objects can be releasably adhered thereto. The frame assembly can be supplied as a part of a composite that can provide other separable smaller bulletin boards or frames that also can have pressure sensitive adhesive accessible along their front surfaces.
