  • 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.

  • Patent number: 9619195
    Abstract: Systems, methods, and computer-readable media for transmitting data using invisible light via a display assembly of an electronic device are provided. This may enable more data to be transmitted simultaneously via a single display assembly of a limited size. For example, a single display assembly may simultaneously transmit a first type of data using visible light that may be comprehensible to a user (e.g., textual information that may be legible to a human) as well as a second type of data using invisible light that may be machine-readable (e.g., a barcode that may be detected by a scanner device but that may not be seen by a human).

  • Publication number: 20160033342
    Abstract: An object can depress an input device, such as, for example, a function button in an electronic device. A resistive element having a mechanically resistive force can be disposed to resist the depression or movement of the input device. One or more electrodes can be disposed to provide a measure of capacitance based on the depression of the input device. A shield can be disposed to reduce the parasitic capacitance between the one or more electrodes and the object. The electronic device can include a fingerprint sensor operably connected to at least one of the one or more electrodes.
