Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.

Abstract: A head-mounted device may include a main housing portion and a fabric head band for supporting the head-mounted device on a user's head. The fabric head band may include first and second flat knit end portions without ribs and a ribbed fabric extending between the first and second flat knit end portions. The ribbed fabric portion may include a stretchable inner fabric layer formed from mesh fabric. A first set of ribs may be formed on a first side of the inner fabric layer and a second set of ribs may be formed on a second opposing side of the inner fabric layer. The head band may include one or more pockets. A pocket along the border of the head band may receive a cord. A pocket at one of the end portions may receive a user input device or other electronic component.

Abstract: Electrodes that can be formed in a flexible band of a wrist-worn device to detect hand gestures are disclosed. Multiple rows of electrodes can be configured to detect electromyography (EMG) signals produced by activity of muscles and tendons. The band can include removable electrical connections (e.g., pogo pins) to enable the electrode signals to be routed to processing circuitry in the housing of the wrist-worn device. Measurements between signals from the active electrodes and one or more reference electrodes can be obtained to capture EMG signals at a number of locations on the band. The measurement method and mode of operation (lower power coarse detection or higher power fine detection) can determine the location and number of electrodes to be measured. These EMG signals can be processed to identify hand movements and recognize gestures associated with those hand movements.

Abstract: An item may be formed from structures that include holes. Stitching may be used to form a seam that joins the structures. The stitching may be formed from a chain stitch that passes through the holes. The holes may be formed from loops of knit fabric or other holes. Leather layers, polymer layers, fabric layers, and other structures with holes may be joined using the stitching. During fabrication, a layer of material with holes may be placed on an adjustable-shape fixture having a bed of needles. The shape of the bed of nails in the adjustable-shape fixture may then be changed. After the fixture has been used to transform the shape of one or more of the structures, the structures may be placed on needles in an assembly fixture and the stitching between the structures may be formed. The item may be an electronic device cover or other item.

Abstract: A system may include an electronic device that communicates with one or more wearable tags. The wearable tags may be placed on different parts of a user's body or clothing and may be used for one or more health-related functions such as posture monitoring, sun exposure monitoring, physical therapy, running assistance, fall detection, and other functions. The wearable tag may have different types of sensors that gather different types of sensor data depending on the health-related function that the wearable tag is being used for. A user may configure, control, and receive data from the wearable tag using an electronic device. The electronic device may be used to determine the location of the wearable tag on the user's body and to determine the desired health-related function for the wearable tag based on user input or based on sensor data gathered from the wearable tag.

Abstract: An item such as a glove may be formed from knitted fabric. The knitted fabric may form fingers for the glove and may form pockets in the fingers. Sensors such as inertial measurement units may be placed in the pockets to measure movements of a user's fingers in the glove. The sensors may be coupled to control circuitry in the glove using conductive yarn in the knitted fabric. The conductive yarn may form courses in the knitted fabric that run along each finger. Haptic components and other electrical components may be coupled to the control circuitry using the conductive yarn. Electrodes may be formed from metal-coated strands of material in the fabric on the sides of each finger. The wireless or wired communications circuitry coupled to the control circuitry may be used to convey information such as user finger movement information to external equipment.

Abstract: An article of footwear may have a sole structure and an upper that includes a foundation element, a tensile strand, and a securing strand. The tensile strand is located adjacent to an exterior surface of the foundation element and substantially parallel to the exterior surface for a distance of at least five centimeters. The securing strand joins or secures the tensile strand to the foundation element. Although the thicknesses may vary, a thickness of the tensile strand may be at least three times the thickness of the securing strand. In some configurations, a backing strand may also assist with joining the securing strand to the foundation element.

Abstract: A composite element includes a base or textile layer, a thermoplastic polymer material, a thread, and a cover layer. The base layer has a first surface and an opposite second surface.

The thread has a section lying adjacent to the first surface layer and substantially parallel to the first surface throughout a distance of at least five centimeters, and the thread is bonded to the base layer with the polymer material. The cover layer is located adjacent to the first surface and bonded to the base layer with the polymer material, and the section of the thread is located between the cover layer and the base layer.
