    Abstract: A module includes a permanent magnet biased electromagnetic haptic engine, a constraint, and a force sensor. The force sensor includes a stator and a shuttle. The constraint is coupled to the stator and the shuttle. The force sensor is at least partially attached to the permanent magnet biased electromagnetic haptic engine and configured to sense a force applied to the module. The constraint is configured to constrain closure of a gap between the stator and the shuttle and bias the shuttle toward a rest position in which the shuttle is separated from the stator by the gap.

    Abstract: A wearable device is coupled to a band including multiple modular functional band links that are each electrically and mechanically connected to one or more other of the band links and/or the wearable device and include one or more electronic components. In various implementations, the wearable device may receive identifiers from each of the band links, determine functionality available using the identifiers, and communicate with the band links to utilize the determine functionality. In some implementations, the band links may include multiple different output devices and the wearable device may determine to provide an output pattern and signal the respective output devices according to the output pattern. In various implementations, the band links may include multiple different input devices and the wearable device may receive input indications from the input devices and perform an action based on a pattern in which the input indications were detected by the respective input devices.

    Abstract: A haptic actuator may include a housing having opposing first and second ends and first and second coils carried by the housing adjacent respective first and second ends thereof. Each coil may have a respective passageway therethrough. The actuator may include a field member including first and second masses adjacent respective first and second ends of the housing, and a permanent magnet having first and second ends coupled to respective ones of the first and second masses. The actuator may also include first and second flexures mounting respective first and second masses to the respective first and second ends of the housing so that the field member is reciprocally movable within the passageways of the coils responsive to powering the coils and so that the ends of the permanent magnet are within respective passageways of the coils when the coils are unpowered.

    Abstract: Systems, methods, and computer-readable media provide multiple modes of haptic feedback for an electronic device using a single haptic actuator. Adjusting a parameter (e.g., frequency) of an actuator waveform generated by the single haptic actuator may affect how a mechanical coupling between the haptic actuator and a portion of the electronic device produces a device waveform at that device portion from the actuator waveform. A first mechanical coupling with a first response characteristic (e.g., stiffness or resonance frequency) may be provided between the haptic actuator and a first portion of the electronic device (e.g., a user input component of the electronic device), while a second mechanical coupling with a different second response characteristic may be provided between the haptic actuator and a second portion of the electronic device (e.g., the device housing of the electronic device) to selectively provide localized haptic feedback at the first portion of the electronic device.

    Abstract: A reluctance haptic engine for an electronic device includes a core, an attractor, and one or more flexible support members. The core and/or the attractor may be coupled to an input structure, such as a button cap, trackpad cover, touchscreen cover, or the like. In an unactuated configuration, flexible support members maintain a gap between the core and the attractor. An electrical current may be applied to one or more conduction loops of the core to actuate the reluctance haptic engine and provide a haptic output by moving the input structure. The electrical current may cause a magnetic flux that results in a reluctance force that pulls the attractor and the core together and causes the input structure to move (e.g., translate, rotate, oscillate, vibrate, or deform) to produce a haptic output.
