Abstract: An eyewear device has an antenna system having at least one element which contributes to wireless signal transmission, and which is thermally connected to a heat-generating electronic component of the eyewear device to serve as a heat sink for the electronic component. A driven antenna element and/or a plurality of PCB extenders electrically-connected to a PCB ground plane can thus be employed for both signal transmission and heat management.

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 cooling device generating unidirectional air flow to cool an electrical component. The cooling device is an equivalent of an electrical acoustic diode to make air flow only one direction. A speaker generates air flow in a first passageway to a cavity, and then expels air out from the cavity through a second passageway. An electrical component is cooled by the air flow, and may be positioned adjacent the passageways, or positioned in the cavity. In one example, eyewear having an electrical component positioned in a temple is cooled by the cooling device.

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: 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: A phase change material (PCM) is positioned about a battery of an eyewear device such that a latent energy of the PCM transfers to the battery as the ambient temperature drops to maintain a battery temperature. The latent energy maintains the temperature of the battery until the PCM loses it latent energy and converts to a solid phase. At normal operating temperatures, the PCM is in the liquid phase.
