  • Patent number: 10162418
    Abstract: An input device may include a wire element and a moveable substrate coupled to the wire element. The moveable substrate may include various wire alignment features. The input device may further include an input surface disposed above the moveable substrate. The input device may further include various sensor electrodes coupled to the input surface. The input device may further include a haptic actuator coupled to the moveable substrate. The haptic actuator may displace the moveable substrate in a direction substantially parallel to a plane of the input surface. The wire element may return the moveable substrate to an original position. The wire alignment features may allow, in response to an applied force by the haptic actuator and to the moveable substrate, a displacement of the moveable substrate in the direction that is substantially parallel to the plane of the input surface.

  • Patent number: 10161391
    Abstract: A haptic actuator and method for manufacturing the same. The haptic actuator may include a slider having first interlocking sliding features and a first engagement surface; and a base having second interlocking sliding features and a second engagement surface. The second interlocking sliding features may be configured to engage with the first interlocking sliding features. The haptic actuator may also include a shape memory alloy disposed between the first engagement surface and the second engagement surface; and a pair of ohmic contacts disposed through the base and are in direct contact with the shape memory alloy. The shape memory alloy may contract and causes displacement of the slider relative to the base from a first position to a second position in response to a current applied to the shape memory alloy through the pair of ohmic contacts.

  • Patent number: 9947493
    Abstract: Magnetically biased retracting key assemblies and keyboards are provided. A key assembly includes a touch surface for receiving a press input from a user and a planar-translation-effecting (PTE) mechanism configured to guide as the keycap moves from an un-pressed position toward a pressed position. The key assembly also includes a ready-return mechanism configured to magnetically biased the keycap in the un-pressed position, the ready-return mechanism including a slider mechanism positioned beneath the keycap and coupled to the PTE mechanism. When the press surface receives a press input the slider mechanism translates away from the magnet as the PTE mechanism guides the keycap from the un-pressed position toward the pressed position. In some embodiments, the PTE mechanism and the ready-return mechanism translate with respect to a chassis layer providing a key retraction feature for the key assembly or keyboard.
