    Abstract: One or more strain sensors can be included in an electronic device. Each strain sensor includes a strain sensitive element and one or more strain signal lines connected directly to the strain sensitive element. The strain sensor(s) are used to detect a force that is applied to the electronic device, to a component in the electronic device, and/or to an input region or surface of the electronic device. A strain sensitive element is formed or processed to have a first gauge factor and the strain signal line(s) is formed or processed to have a different second gauge factor. Additionally or alternatively, a strain sensitive element is formed or processed to have a first conductance and the strain signal line(s) is formed or processed to have a different second conductance.

    Abstract: An input/output device for a computing device including one or more touch sensors and one or more force sensors. The touch sensors sense data including one or more locations at which a contact or near-contact occurs. The force sensor sense data including a measure of an amount of force presented at the one or more locations at which a contact occurs. The touch sensors and the force sensors responsive to signals occurring in response to whether the signals are in response to contact or in response to an amount of force. The input/output device also includes one or more circuits coupled to the touch sensors and to the force sensors, and capable of combining information from both sensors.

    Abstract: An electronic device may be provided with a display mounted in a display frame assembly that includes a plastic structure overmolded over a display frame. A housing midplate may be used to provide the electronic device with mechanical rigidity and strength, and may also be used as a sensor plane. For sensor plane applications, accurate placement and assembly of the midplate in the housing can be critical. The housing midplate may be accurately assembled to the display frame using connections formed using welded tabs, welded and screwed nuts, overmolded plastic heat stake structures, or overmolded plastic structures and adhesive. Rework and repair operations may be performed by disconnecting connections such as welds using cutting equipment, by using solvent to dissolve adhesive, by unscrewing welded nuts, or by removing heat stake structures. Following rework or repair, a fresh midplate and associated components may be attached to the display frame.

    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 response 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 strain signals.

    Abstract: A method of calibrating a force sensor that includes an input surface and an array of sensing elements. The input has a number of test locations and is deformable under applied force. The force sensor is mounted in a predetermined test orientation. For each test location of the plurality of test locations on the input surface of the force sensor a predetermined test force to the test location. An element calibration value is measured for each sensing element of the array of sensing elements of the force sensor. An (x, y) deformation map of the input surface of the force sensor corresponding to the application of the predetermined test force to the test location is determined based on the measured element calibration values.
