    Abstract: A reluctance haptic engine for an electronic device includes a core, an attractor plate, and mechanical suspension. The core and/or the attractor plate may be coupled to an input structure, such as a button cap, a trackpad cover, or a touchscreen cover. In an unactuated configuration, flexible support members maintain a gap between the core and the attractor plate. 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 to produce a haptic output.

    Abstract: A portable electronic device may include a housing member defining a side surface of the portable electronic device, a portion of the housing member defining a side wall of a hole extending through the housing member, a button member positioned along the side surface and defining a chassis portion and a hollow post extending into the hole defined through the housing member, and a first waterproof seal defined between the hollow post and the side wall of the hole. The portable electronic device may also include a biometric sensing component coupled to the chassis portion, a flexible circuit element extending through the hollow post and conductively coupling the biometric sensing component to a component within the housing, and a second waterproof seal defined within the hollow post.

    Abstract: A force input sensor includes a load cell to adapt a compressive force applied to the force input sensor into a strain experienced by a strain sensor in the load cell. In particular, the load cell includes two compression plates separated from one another by a gap so as to define a volume between them. A flexible substrate (a “diaphragm”)—includes a strain sensor and is disposed and supported within the volume. One of the two compression plates includes a feature (a “loading feature”) that extends toward a central region of the flexible substrate. As a result of this construction, when the compression plates receive a compressive force, the loading feature induces a bending moment in the flexible substrate, thereby straining the strain sensor.
