  • Patent number: 9983715
    Abstract: Systems and methods related to piezoelectric based force sensing in touch devices are presented. One embodiment, for example, may take the form of an apparatus including a touch device having a deformable device stack and a piezoelectric element positioned relative to the deformable device stack such that the piezoelectric element deforms with the deformable stack. Deformation of the piezoelectric element generates a signal having a magnitude discernable as representative of an amount of force applied to the touch device.

  • Publication number: 20180121006
    Abstract: An electronic device that senses home button inputs through ultrasonic force sensing. The electronic device may correlate that amount of force that a user applies to the home button with a specific home button command. In certain embodiments, the system may combine the force of touch information with other information that is sensed for a particular touch to correlate the touch input with a greater number of home button commands. A home button embodiment discussed herein may include a home button image that is displayed on a touch sensitive panel. In other embodiments, a home button may be located outside of the boundaries of a touch sensitive panel.

  • Patent number: 9952703
    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.

  • Patent number: 9851828
    Abstract: A touch sensitive input system for an electronic device includes a deflection sensor configured to generate a deflection signal based on deflection of a control or sensing surface, and a processor in signal communication with the deflection sensor. The processor is operable to generate a deflection or displacement map characterizing displacement of the surface based on the deflection signal, and a force map characterizing force on the surface based on a transformation of the displacement map. The transformation may be based on a generalized inverse of a compliance operator, where the compliance operator relates the displacement map to the force map. The compliance operator is not necessarily square, and does not necessarily have a traditional inverse.

  • Publication number: 20170300161
    Abstract: An optical force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.

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.

  • Patent number: 9680975
    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.
