  • Patent number: 9831600
    Abstract: Variable-force contacts that may provide a large and stable contact force in a mated state, may provide a large difference in contact force between the mated and an unmated state, and may reduce stray flux in an unmated state. Examples may replace physical springs with magnetic force for improved reliability. These examples may position the magnets to reduce stray flux in an unmated state.

  • Patent number: 9787032
    Abstract: Ground springs for connector receptacles. The ground springs may protect circuitry in an electronic device from stray voltages when a connector insert is inserted into a connector receptacle housed in the electronic device. One example may have a contacting portion located such that when a connector insert is mated with the connector receptacle, the contacting portion of the ground spring electrically connects to a shield of the connector insert before a ground contact of the connector insert electrically connects to a signal contact on a tongue of the connector receptacle.

  • Publication number: 20170093099
    Abstract: Interconnect devices are described. In some examples, an interconnect device can be aligned in a first plane and can include a printed circuit board having a tongue portion and a pin portion. The pin portion can include a plurality of pins extending away from the printed circuit board. The interconnect device can be configured to electrically couple with a main logic board aligned in a second plane. In particular, the plurality of pins can be inserted into corresponding electrical contact locations within the main logic board to form a biplanar connection. The biplanar connection can be made in way that minimizes signal loss for high speed data transfers.

  • Patent number: 9608506
    Abstract: Embodiments described herein may take the form of an electromagnetic actuator that produces a haptic output during operation. Generally, an electromagnetic coil is wrapped around a central magnet array. A shaft passes through the central magnet array, such that the central array may move along the shaft when the proper force is applied. When a current passes through the electromagnetic coil, the coil generates a magnetic field. The coil is stationary with respect to a housing of the actuator, while the central magnet array may move along the shaft within the housing. Thus, excitation of the coil exerts a force on the central magnet array, which moves in response to that force. The direction of the current through the coil determines the direction of the magnetic field and thus the motion of the central magnet array.

  • Publication number: 20170070001
    Abstract: An accessory to device coupling system can include a first magnet array adapted for assembly with respect to a surface of an electronic device and a second magnet array adapted for assembly with respect to a surface of an accessory device, the accessory device configured to interact electrically with the electronic device. The first magnet array can include a first plurality of magnets arranged in a first pattern of alternating polarities, and the second magnet array can include a second plurality of magnets arranged in a second pattern of alternating polarities that corresponds to the first pattern of alternating polarities. The corresponding alternating polarity patterns can cause the second magnet array to couple to the first magnet array with a normalized attraction force only at an intended orientation and alignment, and with less than half of the normalized attraction force at any other orientation and alignment.
