    Abstract: 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.

    Abstract: Apparatuses, systems for electronic wearable devices such as smart glasses are described. The wearable device can comprise a frame, an elongate temple and an articulated joint. The frame can define one or more optical element holders configured to hold respective optical elements for viewing by a user in a viewing direction. The temple can be moveably connected to the frame for holding the frame in position when the device is worn by the user. The articulated joint can connect the temple and the frame to permit movement of the temple relative to the frame between a wearable position in which the temple is generally aligned with the viewing direction, and a collapsed position in which the temple extends generally transversely to the viewing direction. The articulated joint can include a base foot fixed to the frame and oriented transversely to the viewing direction.

    Abstract: An electronic eyewear device having a thermal management device including a vapor chamber in the temples. The temples may have a sheet metal portion thermally connected to heat generating electronics, wherein the vapor chamber is thermally coupled to the sheet metal along a length thereof to disperse heat generated by the electronics. The sheet metal and the vapor chamber may be encompassed by a non-thermally conducting material, such as being over molded by a silicone material, to prevent user contact with the heated sheet metal and vapor chamber. The sheet metal and the vapor chamber are generally planar and lightweight, and they are bent to bias the temples against a user's head when worn to provide preloading.

    Abstract: A method and apparatus for monitoring a surface temperature of eyewear proximate a processor to understand the surface temperature as a function of computer instructions, such as when the computer instructions are modified during software design. A sensor is coupled to the eyewear proximate the processor, such as at a temple of the eyewear including the processor, using one or more layers of tape. A server provides instructions to the processor for execution, such as instructions of an application, which instructions vary the utilization of the processor. A testing device, such as a digital multi-meter, is coupled to the sensor, as well as the server, and displays the surface temperature as a function of the processor utilization. The surface temperature of the eyewear is monitored to ensure the surface temperature does not exceed a temperature threshold.

    Abstract: Apparatuses and systems are disclosed and can include a case for eyewear having an eyewear body carrying onboard electronic components that comprise a heat source that generates heat during electrically powered operation is disclosed. The case can hold the eyewear when the eyewear are in a stowed position. The case can further include one or more supports to support the eyewear in the stowed position within the holding space. One or more heat sinks are integrated with the one or more supports. Each of the one or more heat sinks are thermally conductive coupled with a corresponding heat sink of the eyewear. A first heat conduction pathway is thermally connected to the one or more heat sinks and can extend into the case body to conduct heat from the heat source into the case with the eyewear supported in the stowed position.
