Abstract

A wearable electronic device includes a conductive housing, which has a main body and at least a first pair of conductive lugs external to and mechanically coupled to the main body. The main body of the conductive housing forms at least part of an antenna structure that is adapted for at least one of generating or receiving the wireless radio frequency signal. The wearable electronic device further includes a non-conductive pin, which extends between the ends of the conductive lugs, and a use location attachment. The use location attachment includes a plurality of segments, where at least one of the segments, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, is nonconductive, and where other ones of the plurality of segments of the use location attachment are conductive.

First claim

What is claimed is:

1. A wearable electronic device adapted for supporting wireless radio frequency communications including at least one of generating or receiving a wireless radio frequency signal, the wearable electronic device comprising:
a conductive housing including a main body and at least a first pair of conductive lugs external to and mechanically coupled to the main body, where each of the conductive lugs has a first end that is mechanically coupled to the main body of the conductive housing and a second end which extends away from the main body along a length of the conductive lug, and where the main body of the conductive housing forms at least part of an antenna structure that is adapted for at least one of generating or receiving the wireless radio frequency signal;
a non-conductive pin, which extends between the second ends of the first pair of conductive lugs; and
a use location attachment, which mechanically couples the conductive housing of the wearable electronic device to a use location via the non-conductive pin and the first pair of conductive lugs, the use location attachment including a plurality of segments, where at least one of the segments, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, is nonconductive, and where the other ones of the plurality of segments of the use location attachment are conductive;
wherein the plurality of segments includes a plurality of links, where each link includes a pair of side lobes separated by a cross member, the side lobes facilitating a coupling to a next adjacent link in the plurality of links; and
wherein the non-conductive pin extends through the pair of side lobes and the cross member of the link corresponding to the non-conductive segment, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs.

2. The wearable electronic device in accordance with claim 1 , wherein the non-conductive pin is received within a hole, which extends through the segment of the plurality of segments of the use location attachment, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs.

3. The wearable electronic device in accordance with claim 1 , wherein the segment of the plurality of segments of the use location attachment, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, is at least partially covered by a metalized outer surface.

4. The wearable electronic device in accordance with claim 3 , wherein the metalized outer surface includes a conductive sleeve.

5. The wearable electronic device in accordance with claim 3 , wherein the metalized outer surface includes a non conductive vacuum metallization layer.

6. The wearable electronic device in accordance with claim 1 , wherein the length of the lugs is of a sufficient distance to form a gap between the main body of the conductive housing and the segment of the plurality of segments of the use location attachment, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs.

7. The wearable electronic device in accordance with claim 1 , wherein the use location attachment is a wrist band.

8. The wearable electronic device in accordance with claim 1 , wherein the cross member of the link, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, is non-conductive and includes a metalized surface; and wherein the side lobes of the non-conductive link have a width, which is adapted to reduce an amount that the associated cross member with the metalized surface will electromagnetically couple to the first pair of conductive lugs.

9. The wearable electronic device in accordance with claim 1 , wherein the associated cross members of the links corresponding to the non-conductive segments are encapsulated by a metal sleeve.

10. The wearable electronic device in accordance with claim 1 , wherein the non-conductive pin is received within a hole, which extends through the segment of the plurality of segments of the use location attachment, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, where the hole that receives the non-conductive pin extends through the associated side lobes of the segment most closely mechanically coupled to the non-conductive pin and the first pair of conductive lugs, as well as the associated cross member;
wherein the side lobes associated with the segment most closely mechanically coupled to the non-conductive pin and the first pair of conductive lugs each have a portion, which overhangs the associated cross member, and which partially overlaps a cross member of an adjacent segment in the plurality of segments of the use location attachment, that is further away from the first pair of conductive lugs, where a segment coupling pin extends through a cross member of the adjacent segment that is further away from the first pair of conductive lugs, and the overhang portion of the side lobes of the segment most closely mechanically coupled to the non-conductive pin and the first pair of conductive lugs through a separate set of holes in the overhang portion of the side lobes; and
wherein the hole in the segment most closely mechanically coupled to the non-conductive pin and the first pair of conductive lugs, that receives the non-conductive pin, and the separate set of holes in the overhang portion of the side lobes for receiving the segment coupling pin are spaced a distance that precludes the cross member of the segment of the use location attachment, which most closely mechanically couples to the non-conductive pin and the first pair of conductive lugs, and the cross member of the adjacent segment that is further away from the first pair of conductive lugs from coming into direct physical contact.

11. The wearable electronic device in accordance with claim 1 , where a link coupling pin, which is conductive, is used to mechanically couple together adjacent links.

12. The wearable electronic device in accordance with claim 1 , wherein the conductive housing additionally includes a second pair of conductive lugs external to and mechanically coupled to the main body of the conductive housing, where each of the conductive lugs from the second pair has a first end that is mechanically coupled to the main body of the conductive housing and a second end which extends away from the main body along a length of the conductive lug.
