    摘要: Keyboards and other electronic input devices have a key or keys with glyphs that are invisible to an unaided human eye in a first condition, such as when an underlying display attached to the key is not emitting light. The glyphs are visible through the key or keys when the display emits light. A one-way visibility layer or structure obscures the visibility of the display when viewed from above, but when the display emits light, the light penetrates through the one-way visibility layer, such as by passing through an array of microperforations in the key, and is visible to an onlooker.

    摘要: A unibody magnetic structure having layers of variably magnetized material is disclosed. The unibody magnetic structure can be formed by way of additive manufacturing, such as by a stereolithographic (SLA) process or a selective laser sintering (SLS) process. The SLA process can involve forming the structure from a molten pool of polymer material, with the material having a magnetic component dissolved therein. The SLS process can involve sintering the structure from a powder having a magnetic component. As each layer is formed, the layer can be selectively magnetized with a given polarity and strength. The magnetization of each formed layer can vary, such that the final structure comprises numerous layers having different shapes and sizes, as well as different levels and polarities of magnetization.

    摘要: A backlit partially reflective mirror may be used to form a logo or other structure in an electronic device. The electronic device may have a housing. The housing may have a wall with one or more openings configured to receive one or more corresponding logo-shaped portions of the partially reflective mirror. The partially reflective mirror may be illuminated using backlight illumination from a backlight that is overlapped by the partially reflective mirror. The partially reflective mirror may be formed from one or more protruding structures on a common substrate. One or more thin-film layers may be configured to provide the partially reflective mirror with desired visible light reflection spectrum, a desired visible light transmission spectrum, and a desired visible light absorption spectrum. The reflectivity of the mirror may be configure so that the mirror serves as a one-way mirror for the logo or other structure.

    摘要: Solid-state deposition of materials and structures formed thereof are described. In particular embodiments, solid-state deposition of materials may be utilized for integrated magnetic assemblies. The integrated magnetic assemblies may include a substrate having a cavity that is physically isolated from an environment external from the substrate and a magnetizable magnetic element formed of particles of magnetizable material. The magnetizable magnetic element may be carried within the cavity such that the magnetizable magnetic element fills the cavity and takes on a size and a shape of the cavity.

    摘要: An item may be provided with a body that forms an enclosure. The body may have a body portion that opens and closes along a seam. An elongated magnetic fastener may run along the seam. The magnetic fastener may have first and second strips of elastomeric material on opposing sides of the seam. Magnetic interlocking elements may be partially embedded in the first and second elastomeric strips. The fastener may be formed by injecting uncured elastomeric material having unmagnetized magnetic particles into a mold. While in the mold, a magnetic field may be applied to magnetize the magnetic particles and to align the magnetic particles into magnetized structures. After forming the magnetized structures within the elastomeric material, the elastomeric material may be cured. Once removed from the mold, portions of the elastomeric material may be removed to expose the magnetized structures, which may subsequently be shaped into interlocking fastener elements.

    摘要: An electronic device may have a housing with first and second portions that move relative to each other. The housing may have a hinge that is configured to bend about a hinge axis. Control circuitry in the electronic device may adjust an electrically adjustable device to control resistance of the hinge to bending about the hinge axis. The electrically adjustable device may be an electroactive polymer that that adjusts pressure between two sliding layers of material, may be a magnetorheological device, may be an adjustable component formed from a shape memory material, or may be another electrically adjustable device. One or more sensors in the electronic device may gather sensor data such as touch input, force input, input related to movement of the housing, housing position information, and/or other data. During operation, the control circuitry can adjust the resistance of the hinge to bending based on the sensor data.

    摘要: Items such as electronic devices, fabric-based items, and other items may include strands of magnetic material. The magnetic material may be formed from particles of a rare-earth alloy or other magnetic materials in a binder. Strands of magnetic material may have magnetic cores surrounded by one or more additional layers such as non-magnetic layers or may have non-magnetic cores surrounded by one or more additional layers including a magnetic layer. The strands of material may be uniform along their lengths or may be segmented into non-magnetic and magnetic portions. Items may include fabric formed from intertwined strands of magnetic material. Magnetic material may interact with permanent magnets and electromagnets. Magnetic sensors may monitor for the presence of magnetic portions of a fabric or other structure.
