Abstract: An input device includes an input structure, a magnet attached to the input structure, and an electromagnet. The magnet rotates when the electromagnet is activated, thereby rotating the input structure. The magnet and input structure rotate about a pivot in order to provide haptic and/or visual feedback to a user. The pivot may attach the magnet and input structure to a body, which in turn may be affixed to, or part of, an electronic device. The electromagnet can encircle the body and/or magnet.

Abstract: Strands of material may be intertwined to form fabric for a strap or other structure in an electronic device. Conductive strands in the fabric may have middle-of-strand knots. When current is applied to a conductive strand, the knot in that strand may produce magnetic fields that cause the knot to adjust tension in the fabric. Conductive strands may intersect at nodes. Each node may have a knot formed from one or more conductive strands at the node. An electronic device or other item may have a magnetic field source that applies a fixed or time-varying magnetic field to the fabric. Each node in the fabric may include magnetic material. The magnetic material may be magnetized by applying current through the conductive strands. After magnetization, each node may interact with the magnetic field from the source of magnetic field to thereby adjust fabric tension, shape, movement, etc.

Abstract: An electronic watch includes a housing defining a side surface of the electronic watch, a transparent cover coupled to the housing and defining a front surface of the electronic watch, an image-sensing element, and a crown extending from the side of the housing and defining an imaging surface. The crown may include a light-directing feature configured to direct, onto the image-sensing element, an image of an object in contact with the imaging surface.

Abstract: An electronic device includes a display and an input region separate from the display. The device detects a first portion of a first input on the input region. In response to detecting the first portion of the first input: if the first portion of the first input meets first criteria that do not require a characteristic intensity of the first input to increase above a first intensity threshold in order to be met, the device displays a precursor object of a user interface object that includes one or more selectable options. While displaying the precursor object, a second portion of the first input is detected on the input region, wherein an intensity of the first input increases above the first intensity threshold. In response to detecting the increase in intensity, the device reveals the user interface object by an amount that varies with a current intensity of the first input.
