  • Concealed shock protector for head-mounted device display
    Patent number: 10678059
    Abstract: A device for displaying visual information to a user includes a waveguide and a lens positioned proximate the waveguide. The waveguide and lens are fixed relative to one another at a top portion of the waveguide and a top portion of the lens. An impact absorber is positioned between a part of the waveguide and a part of the lens, where the impact absorber is affixed to only one of the waveguide and the lens.

  • System, apparatus, and method for securing structures
    Patent number: 10323677
    Abstract: Systems, methods, and devices for securing structures include a fastener that includes a threaded body and a head. The head includes a rounded axial protrusion having a first radial diameter, and a noncircular radial portion for securing the fastener. The noncircular radial portion has a second radial diameter greater than the first radial diameter. The noncircular radial portion is positioned between the threaded body and the rounded axial protrusion.

  • Imposing a rotational force during a drop of an electronic device to reduce breakage
    Patent number: 10043610
    Abstract: An apparatus detects a free-fall state of an electronic device, determines an orientation of the electronic device with reference to gravity when the free-fall state is detected, and predicts that the electronic device will strike a surface within a critical angle range. The prediction is based on the detection of the free-fall state and on the orientation of the electronic device. An electromagnetic torque is generated within the electronic device that re-orients the electronic device outside the critical angle. The apparatus comprises a processing system, a free-fall sensor coupled to the processing system, an orientation sensor coupled to the processing system, a magnetic-field generator, and a first coil that is electrically coupled to the processing system.
