    Abstract: A wearable device can include an eyewear body, onboard electronic components, a thermal coupling and a heat transfer device. The eyewear body can hold one or more optical elements mounted on the eyewear body within a field of view of the user. The onboard electronic components can be carried by the eyewear body at a first portion of the eyewear body and can comprise a heat source that generates heat during electrically powered operation thereof. The thermal coupling can be thermally coupled to the heat transfer device at a second portion of the eyewear body. The elongate heat transfer device can be disposed within the eyewear body and can be thermally coupled to the heat source and the thermal coupling. The heat transfer device can extend lengthwise between the heat source and the thermal coupling to transfer heat from the heat source to the thermal coupling.

    IPC: G02B27/01

    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 wearable device is disclosed according to one embodiment. The wearable device can include an eyewear body, onboard electronic components and a heat transfer device. The eyewear body can be configured for wearing by a user to hold one or more optical elements mounted on the eyewear body within a field of view of the user. The onboard electronic components can be carried by the eyewear body at a first portion of the eyewear body and can comprise a heat source that generates heat during electrically powered operation thereof. The elongate heat transfer device can be disposed within the eyewear body and can be thermally coupled to the heat source. The heat transfer device can extend lengthwise between the heat source and the thermal coupling to transfer heat from the heat source through the eyewear body.

    Abstract: Systems and methods for managing temperatures of wearable device components are disclosed. In one aspect, a wearable electronic device includes glasses, a wireless transmitter, an ambient temperature sensor, hardware processing circuitry, and a hardware memory storing instructions that when executed configure the hardware processing circuitry to determine an ambient temperature using the ambient temperature sensor, determine a maximum temperature of the wearable electronic device based on the ambient temperature, determine a temperature of the wearable electronic device, determine a difference between the maximum wearable temperature and the determined temperature of the wearable electronic device, and adjust a transmission rate of the wireless transmitter based on the difference.

    Abstract: Apparatuses, systems for electronic wearable devices such as smart glasses are described. According to one embodiment, the wearable device can include an eyewear body, onboard electronic components, and a core wire. The eyewear body can be configured for wearing by a user to hold one or more optical elements mounted on the eyewear body within a field of view of the user. The onboard electronic components can be carried by the eyewear body and can comprise a heat source that generates heat during electrically powered operation thereof. The core wire can be disposed within the body to form part of a structural framework for at least part of the eyewear body. The core wire can be thermally coupled to the heat source to provide a heat sink for the heat source.
