Patent number: 11106249Abstract: A hinge assembly includes a first and a second set of friction elements engaged each other by an applied force perpendicular to the friction elements. The first and the second set of friction elements are capable of rotational movement about a cylindrical element that passes through each of the friction elements. Also, the first set of friction elements is capable of movement relative to the second set of friction elements. However, the first set friction elements can remain in a fixed position based upon the applied force, until an external force overcomes the applied. During rotation of the first set of friction elements about the cylindrical element, the frictional engagement that controls the position of the first set of friction elements is based primarily on engagement between the friction elements, as opposed to engagement, if any, between the friction elements and the cylindrical element.Type: GrantFiled: June 12, 2019Date of Patent: August 31, 2021Assignee: Apple Inc.Inventors: Aidan N. Zimmerman, Kevin M. Robinson, Scott J. Krahn, Chien-Tsun Chen, Bradley J. Hamel, Arthur Stanley Brigham

Publication number: 20200081483Abstract: Display assemblies for supporting displays on stands or support arms have mount portions to removably attach to the displays using magnetic assemblies and latches. The magnetic assemblies and latches can improve user experience and allow the display to be installed on a support arm from the viewing side of the display and without having to see or reach behind the display. Magnetic structures can center a mount portion of the support arm and a recess of the display and can attract them to each other. Laterally-extending latches can ensure the display is not inadvertently removed. Locking mechanisms can prevent the display from being rotated to a portrait orientation when sufficient space around the display and the necessary user intent is not provided.Type: ApplicationFiled: September 6, 2019Publication date: March 12, 2020Inventors: Kristopher P.

Patent number: 10069392Abstract: 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.Type: GrantFiled: June 2, 2015Date of Patent: September 4, 2018Assignee: Apple Inc.Inventors: Brett W. Degner, Bradley J. Hamel, David H. Narajowski, Jonah A. Harley, Michael E. Leclerc, Patrick Kessler, Samuel Bruce Weiss, Storrs T. Hoen

Patent number: 10031559Abstract: An electronic device (such as a laptop) may selectively latch a base to a lid using a switchable magnet array. In particular, a drive circuit in the electronic device may apply at least a current pulse to a conductor that generates a magnetic field to reverse a direction of a remnant magnetization in the switchable magnet array. By reversing the direction of the remnant magnetization, the electronic device may selectively increase or decrease a magnetic field generated by the switchable magnet array at an attraction plate in the electronic device. This magnetic field may, in turn, result in an attractive force between the switchable magnet array and the attraction plate, thereby selectively latching the base and the lid when the base and the lid are proximate to each other.Type: GrantFiled: September 19, 2016Date of Patent: July 24, 2018Assignee: Apple Inc.Inventors: Bradley J. Hamel, Christiaan A. Ligtenberg, John C. Difonzo, Jean-Marc Gery

Patent number: 9995070Abstract: 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.Type: GrantFiled: August 30, 2016Date of Patent: June 12, 2018Assignee: Apple Inc.Inventor: Bradley J.
