A projector, such as for eyewear, having a first and second shield that individually sink heat from a light source and provide electromagnetic (EM) shielding for the projector, and a processor controlling the projector. The shields sink heat evenly and efficiently, to different portions of the eyewear. In one example, the heat is directed in different directions. The shields encompass the light source and the processor, and they may be parallel to one another. The thickness of the shield coupled to the light source is thicker proximate the light source. The shields may be separated from each other by a thermal insulating material.

A support arm assembly for a head-worn device provides radio frequency (RF) shielding for a projector. A metal support arm, configured to structurally attach to a rear structural element and an optical element holder of the head-worn device, forms a rear face, a bottom face, and a top face of an enclosure. A metal front face of the enclosure attaches to the optical element holder, and defines a front aperture for permitting passage of light from an exit pupil of the projector toward an input optical element. The metal support arm forms a structural support joining the optical element holder to the rear structural element without placing mechanical load on the projector. A first side face of the enclosure and a second side face of the enclosure are electrically coupled to the metal support arm.

An article includes a hollow enclosure defining a void. The void has a first section and a second section separate from the first section. An electronic component is housed in the first section and the second section of the void. A low pressure mold material is molded into the first section of the void and cured around a first segment of the electronic component to encapsulate the first segment of the electronic component. A support seal is inserted into the second section of the void adjacent a second segment of the electronic component. The support seal defines a sealing barrier on one side of the low pressure mold material that limits the flow of low pressure mold material out of the first section of the void.

A method of dissipating heat generated by imaging devices and processing devices of a wearable electronic eyewear device includes providing a first heat sink thermally connecting the imaging devices to a frame of the eyewear device to sink heat to the frame and providing a second heat sink thermally connecting the processing devices to respective temples of the eyewear device to sink heat to the respective temples. The first and second heat sinks are thermally insulated from each other to direct the heat to different portions of the eyewear device. The processing devices may include a first co-processor disposed in a first temple connected to a first end of the frame and a second co-processor disposed in a second temple connected to a second end of the frame. The resulting eyewear device spreads the heat from heat generating devices over a larger area to minimize overall heating.

Eyewear having a frame, a hinge, and a hyperextendable temple. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. The extender may include a bushing and a spring that allows the temple hyperextension, and which also creates a bias force to urge the temple against a user's head during use.

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.

A device includes a frame and a waveguide. The waveguide has a first end fixedly coupled to a first portion of the frame, and a second end proximal to a second portion of the frame and detached from the frame. When the frame deforms to displace the first portion and the second portion relative to each other, the second end of the waveguide is not displaced relative to the first end of the waveguide as a result of the frame deforming.

A slide switch with an elastomer web for eliminating slide backlash and rattle. The elastomer web is disposed in the motion path of a mechanical slider and biases the slider to contact a switch nub. The biased slider eliminates a loose translational motion of the mechanical slider and therefore a user's perception of loose motion or backlash when actuating the switch. The elastomer web improves the user's perception of the mechanical slider's quality. Additionally, the elastomer web allows for larger assembly tolerances between the mechanical slider and the switch nub. An increased assembly tolerance improves yield for mechanical parts and reduces the cost of manufacturing.

An augmented reality system can include a headset frame wearable by a user. A window disposed in or on the headset frame can include adjacent first and second window regions. When the headset frame is worn by the user, a field of view of an eye of the user can extend through at least part of the first window region. A camera can be disposed in or on the headset frame. When the headset frame is worn by the user, the camera can have a field of view that is directed away from the user and through the second window region. A controllably dimmable filter can be located adjacent to the window in the field of view of the eye and the field of view of the camera. The controllably dimmable filter can have a controllable opacity that determines a visibility of the camera through the second window region.

Eyewear having a frame, a hinge, and a hyperextendable temple having a flexible printed circuit (FPC) including service loops. An extender is coupled to the hinge and the temple, and the extender extends with respect to the hinge allowing hyperextension of the temple with respect to the frame. A first service loop allows extension of the FPC when the temple rotates about the hinge, and a second service loop allows the temple to be radially extended away from the hinge.

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.
