  • Publication number: 20180080598
    Abstract: A counterbalanced display stand can be used with a tablet or other suitable portable electronic device. The display stand can allow for tilt, rotation, and lateral movement in multiple directions to arrive at a desired display position. A 4-bar linkage arrangement can allow for such movements, which can be manual from a user and/or motorized through other device components. The display stand can be counterbalanced such that minimal friction is required to hold the device at a desired display position. A magnetic connector can detachably connect the device to the display stand. A feedback component can facilitate an automated repositioning of the display stand in response to changing conditions.

  • Publication number: 20180058120
    Abstract: An electronic device with an enclosure having a base and a base is disclosed. The electronic device can include a shaft coupled with the base and the base. The shaft can be coupled with a torque component engagement feature that provides a frictional engagement with the shaft. The torque component engagement feature can magnetically couple with a magnet, or magnets. The electronic device can also include a magnetic assembly configured to magnetically couple with the shaft engagement. The magnetic assembly can provide a first magnetic field that magnetically couples the torque component engagement feature with the magnetic assembly. However, the magnetic assembly can change to a second, reduced magnetic field less than the first magnetic field. When the display assembly is rotated toward the base, the magnetic assembly changes to the second magnetic field, and the torque component engagement feature magnetically decouples from the magnetic assembly based on the reduced magnetic field.

  • Publication number: 20180013231
    Abstract: Magnetic connectors that may be readily manufactured and provide a high landed force and labels for magnetic connectors that may protect magnets or magnetic elements in the connectors, provide an aesthetically pleasing appearance, and improve the magnetic performance of the connectors. In various examples, power and signal paths may be formed using contacts that are separate from magnets or magnetic elements, paths may be formed using magnets or magnetic elements, or paths may be formed using a combination of contacts and magnets and magnetic elements. The magnets may have various arrangements. One or more magnets may be used in conjunction with magnetic elements. The interface surface of these magnets and magnetic elements may have various contours, such as flat, spline, or involute.

  • 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.

  • Patent number: 9541959
    Abstract: An electronic device is disclosed that redirects light escaping from a display assembly light source to an illuminable region of the electronic device. In some embodiments, the electronic device includes a light guide panel arranged along a rear surface of the display assembly and configured to receive light escaping from a lateral side of the light source. The light guide panel can then be arranged to transport that light to a position behind the illuminable region and emit it back out in a focused beam having a size about the same as the illuminable region. In some embodiments the illuminable region can be a logo or device identifier.

  • Publication number: 20160313766
    Abstract: A multipart computer housing is described. The multipart computer housing includes at least a structural support layer and a body. The body includes at least an outer layer formed of lightweight flexible material and an inner layer attached to the outer layer. The inner layer is connected to the support layer forming a load path between the inner layer and the structural support layer. A load applied to the multipart computer housing is transferred by way of the load path to the support layer without substantially affecting the outer layer.

  • Patent number: 9348372
    Abstract: An electronic device such as a portable computer including a base and a lid is provided. The electronic device also includes a hinge assembly that facilitates pivoting movement between the lid and the base. The hinge assembly includes a body and a shaft configured to respective engage one of the base and the lid. The hinge assembly also includes a clutch mechanism. The clutch mechanism may include a friction member that induces friction during movement of the lid to help retain the lid in a user-selected angular position with respect to the base. Further, the clutch mechanism may include a spring that extends through a cavity defined through the shaft. The spring may be affixed to the shaft at one end and affixed to the body at a second end. Thereby, movement of the lid may be assisted or opposed by torsion in the spring, so as to improve a user experience.

  • Patent number: 9282652
    Abstract: Magnetic elements and attractors may be employed to secure a top case and a bottom case of a housing of a personal computing device. The magnetic elements may include a magnet that produces a magnetic field and a shunt. The shunt may direct the magnetic field through an opening to a pocket in which the magnet is received. Accordingly, flux leakage may be reduced and the bottom case may be secured to the top case. Magnetic elements and attractors may also be employed to secure a lid portion of the portable computing device to the housing thereof.
