Abstract: Embodiments described herein may take the form of an electromagnetic actuator that produces a haptic output during operation. Generally, an electromagnetic coil is wrapped around a central magnet array. A shaft passes through the central magnet array, such that the central array may move along the shaft when the proper force is applied. When a current passes through the electromagnetic coil, the coil generates a magnetic field. The coil is stationary with respect to a housing of the actuator, while the central magnet array may move along the shaft within the housing. Thus, excitation of the coil exerts a force on the central magnet array, which moves in response to that force. The direction of the current through the coil determines the direction of the magnetic field and thus the motion of the central magnet array.
Abstract translation: 本文描述的实施例可以采取在操作期间产生触觉输出的电磁致动器的形式。 通常，电磁线圈缠绕在中心磁体阵列周围。 轴通过中心磁体阵列，使得当施加适当的力时，中心阵列可以沿着轴移动。 当电流通过电磁线圈时，线圈产生磁场。 线圈相对于致动器的壳体是静止的，而中心磁体阵列可以沿壳体内的轴移动。 因此，线圈的激励对中心磁体阵列施加力，响应于该力而移动。 通过线圈的电流的方向确定磁场的方向，从而确定中心磁体阵列的运动。

Abstract: Disclosed herein are electronic devices having a deformable surfaces through which a user can provide inputs to the device by applying a force such as a pinch or a squeeze. A particular embodiment is an earpiece with the deformable surface part of an elongate section extending from an earbud. The deformable surface includes an incompressible hyperelastic material and a pressure sensor. The pressure sensor includes a pressure sensing element and a void defined between the pressure sensing element and the incompressible hyperelastic material. An applied force is transferred by the incompressible hyperelastic material to compress the void and change an internal pressure thereof. The changed pressure is detected by the pressure sensor, and can result in changed operation of the electronic device.

Abstract: A fabric-based item such as a fabric glove may include force sensing circuitry. The force sensing circuitry may include force sensor elements formed from electrodes on a compressible substrate such as an elastomeric polymer substrate. The fabric may include intertwined strands of material including conductive strands. Signals from the force sensing circuitry may be conveyed to control circuitry in the item using the conductive strands. Wireless circuitry in the fabric-based item may be used to convey force sensor information to external equipment. The compressible substrate may have opposing upper and lower surfaces. Electrodes for the force sensor elements may be formed on the upper and lower surfaces. Stiffeners may overlap the electrodes to help decouple adjacent force sensor elements from each other. Integrated circuits can be attached to respective force sensing elements using adhesive.

Abstract: An electronic device has a force sensor that determines a measure of applied force from a user contacting a cover glass of the device. In one embodiment, a frame at least partially encloses an interior of the electronic device and has an open end. A cover glass covers the open end of the frame and is movably connected to the frame to allow movement of the cover glass in response to one or more forces applied to an external surface of the cover glass. A plurality of strain probes is positioned under the cover glass, between the cover glass and the frame, and is arranged to output a plurality of strain signals responsive to the one or more forces applied to the cover glass. A force processing module is configured to at least calculate an amount of force applied to the cover glass based on the plurality of stain signals.
