Abstract: An item such as a removable device cover or a portable electronic device may have a fabric hinge. The item may have first and second structures that are configured to rotate relative to each other. The fabric hinge may have first and second fabric layers that are coupled to the first structure and third and fourth fabric layers that are coupled to the second structure. A center portion of the fabric hinge may have one side that is coupled to the first and second fabric layers and an opposing second side that is coupled to the third and fourth fabric layers. In the center portion, first strands of material may extend outwardly into the first and fourth fabric layers and second parallel strands that are interspersed with the first strands may extend outwardly into the second and third fabric layers.

Abstract: Conductive yarns in a knitted fabric may include insulating cores covered with metal layers that form signal paths. Open circuits may be formed in the yarns by removing metal from the insulating cores at selected locations within the yarns. The fabric may be formed from rows of interlocked loops of the yarn. The open circuits may be located on the loops so that each loop with an open circuit has a first segment of the metal layer that is separated from a second segment of the layer by a portion of the loop from which the metal layer has been removed. Each electrical component may have terminals that span a respective one of the open circuits and that are shorted respectively to the metal of the first and second segments.

Abstract: A fabric-based item may include a housing that is covered in fabric. Areas of the fabric may overlap input circuitry such as button switches, touch sensors, force sensors, proximity sensors, and other sensing circuitry and may overlap other components such as light-emitting components and haptic output devices. The fabric-based item may include control circuitry that gathers user input from the input circuitry and wireless communications circuitry that the control circuitry uses to transmit remote control commands and other wireless signals in response information from the input circuitry. The fabric-based item may have a weight that is located in the housing to orient the housing in a desired direction when the housing rests on a surface. A movable weight may tilt the housing in response to proximity sensor signals or other input. Portions of the fabric may overlap light-emitting components and optical fiber configured to emit light.

Abstract: Weaving equipment may include strand positioning equipment that positions warp strands and that inserts weft strands among the warp strands to form fabric. The weaving equipment may include one or more guide arms that pushes warp strands in the weft direction during weaving. Fabrics having warp strands that extend in both the warp direction and the weft direction may be used in forming circuitry in fabrics such as touch sensor circuitry. For example, a touch sensor in a fabric may be formed using first conductive warp strands that form first touch sensor electrodes and second conductive warp strands that form second touch sensor electrodes that overlap with the first touch sensor electrodes. The second conductive warp strands may each have a first portion that extends in the warp direction and a second portion that extends in the weft direction across the first touch sensor electrodes.

Abstract: A fabric case for an electronic device may include a back panel having a periphery and a sidewall that extends around the periphery. The back panel and the sidewall may be joined monolithically or may be joined using seams. A monolithic fabric case may be formed by knitting rows of loops to create a sidewall, knitting rows of loops to create a back panel, and joining the loops of the sidewall with the loops of the back panel as the back panel is being knitted. A fabric case with seams may be formed by attaching a fabric sidewall to a fabric back panel using a seam such as a chain stitch. The sidewall may be a seamless tube of fabric that extends continuously around the back panel. The seamless tube may be folded to create interior and exterior walls. A stiffener may be interposed between the interior and exterior walls.

Abstract: A touch-sensitive textile device that is configured to detect the occurrence of a touch, the location of a touch, and/or the force of a touch on the touch-sensitive textile device. In some embodiments, the touch-sensitive textile device includes a first set of conductive threads oriented along a first direction, and a second set of conductive threads interwoven with the first set of conductive threads and oriented along a second direction. The device may also include a sensing circuit that is operatively coupled to the first and second set of conductive threads. The sensing circuit may be configured to apply a drive signal to the first and second set of conductive threads. The sensing circuit may also be configured to detect a touch or near touch based on a variation in an electrical measurement using the first or second set of conductive threads.

Abstract: Strands of material may be intertwined using weaving techniques, knitting techniques, non-woven or entanglement techniques, or braiding techniques. Fabric that is formed from the strands of material may be used in forming a fabric-based item. The fabric based item may include electrical components. The strands may include conductive strands that form signal paths. The signal paths can carry electrical signals associated with operation of the electrical components. Each strand may have an elongated core and a coating. Strands may also include intermediate layers between the cores and coatings. The cores, intermediate layers, and coatings may be formed from polymer without conductive filler, polymer with conductive filler, and/or metal. A polymer core may be provided with recesses to help retain subsequently deposited layers such as a metal coating layer. The recesses may be grooves that extend along the longitudinal axis of the core.

Abstract: A fabric-based item may include fabric formed from intertwined strands of material such as intertwined strands of tubing. The strands of material may include electrophoretic ink formed from charged nanoparticles of different colors in fluid. The electrophoretic ink may be contained within strands of tubing or may be enclosed within encapsulation structures such as encapsulation spheres. Encapsulation spheres or other encapsulation structures may be embedded in clear polymer binder within tubing or other strands. Electroluminescent particles may be included in the clear polymer binder. Electric fields can be applied to the electrophoretic ink in a given area of the fabric using conductive strands that overlap the area, using conductive electrodes such as transparent conductive electrodes on strands of tubing, using coaxial electrodes, or using other electrode structures.
