Wearable computing device accessory for mitigating radio frequency radiation

1 . An accessory for a computing device, the accessory comprising:

a cradle defining a volume configured to receive the computing device, the cradle including:

(i) an interior surface facing the volume and configured to engage with a housing of the computing device; and

(ii) an exterior surface opposite the interior surface; and

a conductive shield disposed between the volume and an object, the conductive shield configured to reduce radiation emitted by at least one antenna of the computing device towards the object, the conductive shield including a plurality of interconnected conductive regions, wherein interconnections between the plurality of conductive regions have a cross-sectional area smaller than a cross-sectional area of each of the plurality of conductive regions, the interconnections configured to reduce an impact of the conductive shield on antenna performance.

2 . The accessory of claim 1 , wherein the cradle is formed of a non-conductive first material, and wherein the conductive shield comprises a layer of a second material affixed to the cradle.

3 . The accessory of claim 2 , wherein the layer of the second material is affixed to the one of the exterior surface or the interior surface.

4 . The accessory of claim 2 , wherein the layer of the second material is embedded within the cradle, between the interior surface and the exterior surface.

5 . The accessory of claim 2 , wherein the layer of the second material is selected from the group consisting of: a metallic mesh, a fabric, and a metal sheet.

6 . The accessory of claim 1 , wherein at least a portion of the conductive shield is disposed within a volume projected from a portion of the interior surface adjacent to the antenna when the computing device is received in the cradle.

7 . The accessory of claim 6 , wherein the portion encompasses half of a surface area of the conductive shield.

8 . The accessory of claim 1 , wherein the conductive shield includes a first region configured to mitigate radiation emitted by an antenna of the computing device towards the object, and a second region configured to mitigate radiation emitted by another antenna of the computing device towards the object.

9 . The accessory of claim 1 , further comprising:

a second conductive shield affixed to the cradle at a position distinct from a position of the conductive shield, the second conductive shield configured to mitigate radiation emitted by at least one other antenna of the computing device towards the object.

10 . The accessory of claim 1 , further comprising:

a mount configured to engage with an object;

wherein the exterior surface of the cradle is configured to connect to the mount.

11 . The accessory of claim 10 , wherein the mount includes a first surface configured to engage with the object; and

wherein a distance between the interior surface of the cradle and the first surface of the mount is less than 15 mm.

12 . The accessory of claim 10 , wherein the conductive shield is disposed on the mount.

13 . A wearable cradle for a computing device, the wearable cradle comprising:

an exterior surface configured to couple the cradle to an object;

an interior surface defining a volume configured to receive the computing device, a portion of the interior surface being configured to be disposed adjacent to at least one antenna of the computing device; and

a conductive shield disposed adjacent to the portion of the interior surface, the conductive shield configured to reduce radiation emitted by the antenna towards the object, the conductive shield including a plurality of interconnected conductive regions, wherein interconnections between the plurality of conductive regions have a cross-sectional area smaller than a cross-sectional area of each of the plurality of conductive regions, the interconnections configured to reduce an impact of the conductive shield on antenna performance.

14 . The wearable cradle of claim 13 , wherein the cradle is formed of a non-conductive first material, and wherein the conductive shield comprises a layer of a second material affixed to the cradle.

15 . The wearable cradle of claim 14 , wherein the layer of the second material is affixed to one of the exterior surface and the interior surface.

16 . The wearable cradle of claim 14 , wherein the layer of the second material is embedded within the cradle, between the interior surface and the exterior surface.

17 . The wearable cradle of claim 13 , wherein the exterior surface is configured to engage with a mount to couple the cradle to the object.
