摘要： A double helix actuator is disclosed that includes a double helix coil wound around a movable proof mass that is enclosed within a magnetic structure. The double helix coil and the magnetic structure are arranged relative to each other so that the magnetic field generated by the entirety of the double helix coil contributes to a linear force direction of the actuator. The double helix actuator produces a greater linear force density compared to traditional racetrack coil actuators, where only a portion of the coil contributes to the linear force. The double helix actuator also produces torque in addition to linear force which allows the double helix to provide unique haptic sensations in a variety of applications.

摘要： The disclosed embodiments of haptic locomotion use one or more actuators to: 1) determine the properties of contact surfaces to improve various applications that use haptic locomotion; 2) automatically improve power transfer efficiency during wireless charging or cellular or wireless signal reception; 3) increase device accessibility for visually or hearing impaired users; 4) improve speaker and microphone performance; 5) protect a free falling mobile device from impact damage by orienting the mobile device to a low-risk orientation during free fall, or by driving the mobile device away from a high-risk orientation during free fall; and 6) control asymmetric surface friction using a directional magnetic field provided by an actuator to improve haptic locomotion in a desired direction of travel.

摘要： Locating a lost stylus, or other peripheral input device can be made possible by acoustic resonators integrated within housing structures of the stylus. Acoustic resonators can be formed at an end of the stylus opposite its tip, and can include portions of the stylus outer housing that are thinned down to an engineered thickness that has a particular resonant behavior or frequency. In some examples, acoustic resonators can be formed at a cap portion of the stylus, and can include a resonant diaphragm attached to at least a portion of a cap boundary. Cap coverings for the cap portion can optionally have openings to allow ventilation for changes in air pressure generated beneath the covering. In some examples, an electronic device can communicate a location request to the stylus and can cause the stylus to generate an acoustic signal for a specified target detector using the acoustic resonators.

摘要： A haptic actuator may include first and second bodies movable along an arcuate path of travel. The haptic actuator may also include a biasing member coupled between the first and second bodies. At least one electrical coil may be configured to move the first and second bodies to produce a haptic effect.

摘要： A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective at least one flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. Each flexure bearing may include two diverging arms joined together at proximal ends and having spaced distal ends operatively coupled between adjacent portions of the field member and the housing. The two diverging arms may each have a reduced size medial portion relative to respective proximal and distal ends.
