A shield can for an electronic eyewear device is described that reduces RF signals emanating from the electronic eyewear device. The shield can is attached to a ground plate of the electronic eyewear device using leaf springs on a side of the shield can. The leaf springs do not add to the stack-up thickness of the shield can assembly and provide a balanced force against the ground plate. The shield can is attached to a printed circuit board and encompasses radio frequency (RF) electronic components to prevent RF signals emanating from the RF electronic components. The leaf springs have a pair of fingers providing the balanced mechanical point force. A conductive pressure sensitive adhesive is also provided to secure a top surface of the shield can to the ground plate along with a thermal paste.

One aspect is an apparatus including a plurality of additively manufactured components each having an adhesive injection channel. The components are connected together such that adhesive injection channels are aligned to form an adhesive path that allows adhesive flow between the components. Another aspect is an apparatus, including an additively manufactured component having an adhesive injection channel and an adhesive flow mechanism comprising at least one of an adhesive side end effector or a vacuum side end effector, the adhesive flow mechanism configured to provide adhesive to the adhesive injection channels.

Assembling structures comprising 3D printed components and standardized components utilizing adhesive circuits

Eyewear hinge assemblies for eyewear that connect temples to a frame. The hinge assemblies include hinge elements that are attached to the temples in an extended state, which stores an initial amount of energy or pre-load. The pre-load biases the temples inwardly and toward one another. After the temples are placed on the user's head, stored energy in the hinge elements can be released as the hinge elements exhibit elastic recoil. This causes the temples to grip the sides of the user's head in a snug and comfortable fit. The hinge assemblies have compact designs with material properties that provide comfortable closing forces while aiding in the reduction of electromagnetic noise from electrical subsystems in the eyewear.

Retention features are provided for joining at least two structural components in a fixtureless assembly system. A first structure including a groove may be configured to contain at least one adhesive, and a second structure may include a tongue configured to contact the at least one adhesive to join the first and second structures. The first structure may also include at least one window that receives electromagnetic (EM) radiation from an EM radiation source into the groove. The at least one adhesive is configured to cure at a first rate upon exposure to one of time or heating, and the at least one adhesive is configured to cure at a second rate faster than the first rate upon exposure to the EM radiation.

Radiation-enabled retention features for fixtureless assembly of node-based structures

Part retention features are disclosed for securing additively manufactured (AM) parts or for securing an AM part with another component, such as a node, panel, tube, extrusion, and the like, while an adhesive is being applied and/or while the adhesive is undergoing expansion due to a subsequent curing process. The retention features described herein can be used in the context of one or more AM parts such that the elements used to house the retention features (e.g., grooves, apertures, elastic elements, etc.) can advantageously be co-printed with the AM part, thereby removing a manufacturing step. The retention features also can be made with flatter profiles than existing solutions, making the overall structure smaller and less cumbersome to assemble.

Mechanical part retention features for additively manufactured structures

A node to panel interface structure for use in a transport structure such as a vehicle is disclosed. In an aspect, the node includes a base, first and second sides protruding from the base to form a recess for receiving a panel, ports for adhesive injection and/or vacuum generation, one or more adhesive regions disposed on a surface of each side adjacent the panel, and at least one channel coupled between the first and second ports and configured to fill the adhesive regions with an adhesive, the adhesive being cured to form a node-panel interface. The node may be additively manufactured. In an exemplary embodiment, the node may use sealant features for including sealants that border and define the adhesive regions, and that may hermetically seal the region before and after adhesive injection. In another embodiment, the node may include isolation features for including isolators for inhibiting galvanic corrosion. In another aspect, adhesive may be filled serially on the adhesive regions on the first side and then on the adhesive regions on the second side. Adhesive may alternatively may be filled in parallel, or concurrently, on the adhesive regions of both sides.
