    摘要: At least some embodiments of the present disclosure an electrostatic sheet jamming device comprising a first sheet having a first conductive layer, a first dielectric layer disposed adjacent to the first conductive layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible, wherein the first sheet and the second sheet are slidable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer. In some embodiments, the applied voltage is less than or equal to a break-down voltage of air at a distance between the first conductive layer and the second conductive layer.

    摘要: The present disclosure provides abrasive articles that include an abrasive layer having a contact surface, a first layer coupled to the abrasive layer, and a second layer coupled to the first layer. The first layer is configured to provide contact pressure to the abrasive layer, such as through a higher hardness than the second layer. The second layer is configured to provide conformability to the abrasive layer, such as through a higher compressibility than the first layer. The resulting abrasive articles may exert a consistent contact pressure against a substrate with increased conformability around the substrate, reduced hysteresis, improved removal rate consistency, and/or improved lifetime over abrasive articles that do not use the multiple layer construction described above.

    摘要: The present application provides a display device that easily reduces an incident amount of an infrared light to a display portion on the basis of maintaining visual confirmation of display information. A display device according to one scheme of the present disclosure comprises: a display portion emitting a visible light of a linearly polarized wave having display information; an infrared light cut-off portion transmitting the visible light from the display portion and reducing an incident amount of an infrared light to the display portion; and a reflecting portion reflecting the visible light transmitted from the infrared light cut-off portion, wherein the infrared light cut-off portion comprises an infrared light cut-off layer, the infrared light cut-off layer has a slow axis, and the slow axis is generally parallel to a vibration direction of the linearly polarized wave.
