An eyewear device includes transmission lines extending through the temples to electrical and electronic components positioned adjacent to edges of a frame. A tether is attached to the temples to enable power and communication flow between the electrical and electronic components rather than through the frame. Proper installation is identified based on communications passing between the electrical and electronic components via the tether. ## Claims ### Claim 1 An eyewear device comprising: a frame configured to support an optical element; a first temple coupled to the frame, the first temple including a first connector, a first transceiver, and a first processor; a second temple coupled to the frame, the second temple including a second connector, a second transceiver, and a second processor; and a tether including a first mating connector on a first end coupled to the first connector and a second mating connector on a second end coupled to the second connector; wherein the first processor is configured to: send, via the first transceiver and the first connector to the tether, a communication signal for delivery to the second processor; receive, from the tether via the first connector and the first transceiver, a responsive communication signal from the second processor via the second transceiver and the second connector; and process the responsive communication signal to identify proper installation of the tether to the first and the second temples. ### Claim 2 (depends on 1) The eyewear device of claim 1, wherein: the first processor and the first transceiver are positioned in the first temple or in the frame adjacent a first edge of the frame; and the second processor and the second transceiver are positioned in the second temple or the frame adjacent a second edge of the frame. ### Claim 3 (depends on 2) The eyewear device of claim 2, wherein the first processor and the first transceiver are positioned in the frame adjacent the first edge, the eyewear device further comprising: a first data line and a first synchronization line extending from the first transceiver to a distal end of the first temple. ### Claim 4 (depends on 1) The eyewear device of claim 1, wherein: the second processor is configured to receive the communication signal from the tether, generate the responsive communication signal, and send the responsive communication signal to the tether. ### Claim 5 (depends on 1) The eyewear device of claim 1, further comprising a notification device supported by at least one of the frame, the first temple, the second temple, or the tether and wherein the first processor is configured to notify a user via the notification device when proper installation of the tether to the eyewear device is identified. ### Claim 6 (depends on 1) The eyewear device of claim 1, wherein the tether is detachably coupled to at least one of the first and second temples. ### Claim 7 (depends on 1) The eyewear device of claim 1, wherein the first temple includes a connector selected from the group consisting of a universal serial bus (USB) connector, a friction fit connector, and a magnetic attachment connector and the tether includes a mating connector selected from the group consisting of a USB connector, a friction fit connector, and a magnetic attachment connector. ### Claim 8 (depends on 1) The eyewear device of claim 1, wherein the tether includes a data line and a synchronization line extending between the first and second mating connectors and a flexible sheath surrounding the data line and the synchronization line. ### Claim 9 (depends on 8) The eyewear device of claim 8, wherein the flexible sheath is selected from the group consisting of silicone, a thermoplastic elastomer, and a fabric. ### Claim 10 (depends on 8) The eyewear device of claim 8, wherein the tether further comprises: a power transmission line, the flexible sheath further surrounding the power transmission line. ### Claim 11 (depends on 1) The eyewear device of claim 1, wherein the frame includes a bridge between a first edge of the frame and a second edge of the frame and wherein there are no transmission lines that pass through the bridge. ### Claim 12 A tether for use with an eyewear device including a frame configured to support an optical element, a first temple coupled to the frame, the first temple including a first connector, a first transceiver, and a first processor, a second temple coupled to the frame, the second temple including a second connector, a second transceiver, and a second processor, the tether comprising: a first mating connector on a first end coupled to the first connector; and a second mating connector on a second end coupled to the second connector; wherein the tether is configured to: receive, from the first connector via the first mating connector, a communication signal for delivery to the second processor; send, to the second connector via the second mating connector, the communication signal for delivery to the second processor via the second transceiver; receive, from the second connector via the second mating connector, a responsive communication signal for delivery to the first processor; and send, to the first connector via the first mating connector, the responsive communication signal for delivery to the first processor via the first transceiver for processing to identify proper installation of the tether to the first and the second temples. ### Claim 13 (depends on 12) The tether of claim 12, wherein the first temple includes a connector selected from the group consisting of a universal serial bus (USB) connector, a friction fit connector, and a magnetic attachment connector and the mating connector of the tether is selected from the group consisting of a USB connector, a friction fit connector, and a magnetic attachment connector. ### Claim 14 (depends on 12) The tether of claim 12, wherein the tether includes: a data line extending between the first and second mating connectors;
