Apple has granted two patents for AR glasses: passive heat dissipation design and digital crown interaction scheme.

CTOnews.com September 6 news, according to the latest list published by the United States Trademark and Patent Office (USPTO), Apple has obtained two patents related to AR glasses, one is passive thermal design, the other patent is digital crown.

CTOnews.com cites patents describing that the AR glasses are coated with transparent and thermally conductive materials such as silver nanowires, which are stable in color, relatively low in cost, good in thermal conductivity, transmittance, etc., and efficient in passive heat dissipation by expanding the effective area.

In the second patent, it is introduced that a digital crown is installed at the position of the AR glasses, which is convenient for the user to interact. In addition to patent expression eye tracking, digital crown is another way to interact. Input at input device 820 by a user's finger 824 may cause application 805 to move or change.
