A set of augmented reality (AR) or virtual reality (VR) glasses are disclosed. The glasses comprise a fiber reinforced structure. The fiber reinforced structure includes a continuous fiber component. The fiber reinforced structure also includes a thermoplastic material injection molded over the continuous fiber component, wherein the thermoplastic material surrounds the continuous fiber component. The glasses also comprise electronics that are coupled to the fiber reinforced structure, wherein the electronics are configured to facilitate presentment of imagery onto a lens of the glasses.

Head-mountable devices can include an arrangement of components that include a waveguide that is decoupled from the ability of system loads to be transferred into the waveguide. Such decoupling can be achieved by utilizing an elastic bond with low stiffness to bond certain components together. This allows the system to flex and deform without transferring stress to the waveguide. Such decoupling can also be achieved by selectively bonding in regions that have relatively lower displacements between a support structure and the waveguide. These measures can help preserve component alignment while allowing a head-mountable device to be lightweight and small in size.

Apparatuses, methods, and systems for a hinge feed antenna of eyewear, are disclosed. One apparatus includes a front frame, a temple arm, and a hinge rotatably connecting the front frame and the temple arm. For an embodiment, the temple arm includes a circuit assembly including at least a radio that supports wireless communication. For an embodiment, the front frame includes one or more antennas traces, wherein the hinge conductively connects the circuit assembly to the one or more antenna traces, and wherein the hinge in combination with the one or more antenna traces form one or more antennas for supporting the wireless communication.
