  • Publication number: 20200280792
    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.

  • Patent number: 10496211
    Abstract: A mobile communication device includes a housing defining an interior volume and a port connecting the interior volume to an environment exterior to the device. The mobile communication device also includes a display viewable through a surface of the housing, a pressure sensor configured to measure an air pressure within the interior volume, an air flow sensor configured to measure an air flow through the port, and a processor. The processor is configured to determine an amount of force applied to the housing using a measurement of the air pressure by the pressure sensor and a measurement of the air flow by the air flow sensor.

  • Patent number: 10466829
    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.

  • Patent number: 10353506
    Abstract: Structures and methods are disclosed for an electronic device having an input surface that uses dual sensors to measure forces applied to the input surface. The forces can be estimated over a greater range of values than would be possible with either sensor alone. A second sensor can be used after a first sensor has reached a limit. A first sensor can be a strain sensor and a second sensor a pressure sensor. Both sensors may be resistance based, with signals from both sensors can be combined and measured by processing circuitry. Each sensor type may be part of planar arrays disposed beneath the input surface.

  • Patent number: 10318089
    Abstract: Several techniques for driving a force sensor to reduce common mode offset are disclosed. The force sensor can include at least one set of individual strain sensitive structures formed on or in a surface of a substrate. Each set of individual strain sensitive structures can include one or more strain sensitive structures. At least one external resistor is operably connected in series between a first output of one or more transmitter channels and at least one set of strain sensitive structures. The external resistor(s) effectively increases the resistances of the strain sensitive structures to reduce the common mode offset. Additionally or alternatively, one or more signal generators may be connected to one or more transmitter channels. Each signal generator is configured to produce one or more signals that is/are designed to reduce common mode offset.

  • Patent number: 10309846
    Abstract: A strain-responsive sensor incorporating a strain-sensitive element is disclosed. The strain-sensitive element includes a matched-pair of resistive structures disposed on opposite sides of a substrate. One resistive structure is coupled to a crossover, either a physical crossover or a soft crossover, such that current within the resistive structures of the matched pair flows in the same direction. In addition, one resistive structure of the matched pair has a different loop area than the other resistive structure.

  • Patent number: 10296123
    Abstract: A force sensing device can be included in a display. Noise produced by various sources can be injected into the force signals produced by the force sensing device. Example noise sources include, but are not limited to, the display, Johnson or Thermal noise from the force sensing device, system noise, and magnetically-coupled or background noise produced by ambient light sources. A sampling scheme that includes one or more noise cancelling techniques can be employed to reduce the amount of noise in the force signals.

  • Patent number: 10275069
    Abstract: A portable electronic device includes a cover glass, one or more strain gauges operable to indicate force exerted on the cover glass based on deformation of the cover glass, a housing that defines a sway space gap into which the cover glass deforms when the force is exerted on the cover glass, and an incompressible fluid positioned in the sway space gap. The incompressible fluid allows deformation of the cover glass into the sway space gap when the force is exerted on the cover glass and maintains a constant volume under hydrostatic pressure.
