  • Patent number: 9703406
    Abstract: An interference suppression module coordinates devices susceptible to interference such as a touch sensor with potentially interference generating devices such as a display drive matrix, an active haptic device, and so forth. As a result of status signals generated by the interference suppression module, controllers of the susceptible devices may modify the input received to mitigate or avoid interference.

  • Patent number: 9509143
    Abstract: A wide dynamic range charger module is configured to couple a variable power source such as a photovoltaic cell to a load. The module determines a maximum power point (MPPT) of the power source and based at least in part upon that MPPT selects one of a plurality of power converters to provide power to the load. The selection is such that the selected power converter is operating within its operating regime. The selected power converter may further be configured to a pre-determined input admittance which corresponds to the power source.

  • Patent number: 9477306
    Abstract: Substrates for components such as a display, touch sensor, multifunction stackup, and so forth may incorporate one or more haptic actuators configured to generate haptic output. These actuators may be formed from a portion of a body of the substrate, or separate pieces bonded or otherwise affixed to the substrate. Audible output resulting from activation of the actuators may be minimized by coupling the actuators such that they produce a physical displacement of the body of the substrate within, rather than orthogonal to, the plane of the body of the substrate.

  • Patent number: 9307499
    Abstract: A user device transmits data at a first transmit power level. The user device detects a presence of a human body part within a predetermined distance from an antenna of the user device using one or more sensors disposed at a back side of the user device. In response to the detection of the presence of the human body part, the user device transmits information at a second transmit power level that is less than the first transmit power level.

  • Patent number: 9148190
    Abstract: In some implementations, an electronic device includes an actuator having a coil and a magnet, at least one of which may be movable relative to the other. The coil may receive a drive current to cause movement of at least one of the magnet or the coil, such as to provide a haptic output, motivate a loudspeaker, or the like. A transceiver electrically coupled with the coil through a connection circuit may use the coil as an antenna for at least one of sending or receiving a radio frequency communication through the coil. Additionally, or alternatively, the coil may be placed into proximity to a source of a magnetic field to induce an electric current in the coil. The induced electric current may be passed from the coil to a power management system, such as to charge a battery or the like.

  • Patent number: 9131623
    Abstract: Devices and methods for constructing low-profile, minimal-thickness electronic devices using existing production techniques are disclosed in this application. An electronic component and interposer form a sub-assembly. The sub-assembly is placed in an aperture in a circuit board with the interposer providing interconnections between the electronic component and the circuit board. The circuit board is coupled to the electronic component at least by one or more fluidic channels included in the interposer. The sub-assembly placed in the aperture in the circuit board as described herein conceals the thickness of the integrated circuit within the thickness of the circuit board, reducing overall thickness.

  • Patent number: 9030308
    Abstract: User interface experiences with electronic devices are enhanced with feedback cues such as haptic or vibrotactile output feedback. One or more piezoelectric actuators generate haptic output. The one or more piezoelectric actuators may be integrated onto a display substrate, a battery case, a device enclosure, or other component. Such integration may improve propagation of the haptic output to the user, reduce bulk of the electronic device, minimize parts count, and reduce production costs.

  • Patent number: 9019720
    Abstract: Components within a portable device are arranged around a perimeter of a display component to reduce the height of the portable device. Components such as a battery, a main logic board, a wireless networking interface, and so forth may be distributed around a display component such as an electrophoretic display. Distribution of components around the perimeter of the display component rather than behind the display component reduces the height. Furthermore, the placement of components in the perimeter provides a structure for a user to grip the portable device or for placement of user actuable controls.
