Hinge for electronic spectacles
Eyewear including an optical functional member, control electronics, and a sealed electrical connective element connecting the electronics to the optical functional member. The connective element can directly connect the electronics to the optical functional member, or can connect through an intermediate contact, e.g., a plug-and-receptacle. The connective element can be routed from the electronics, around a rimlock of the eyewear to the optical functional member. The connective element can be a conductive compressible member, such as conductive rubber. In some embodiments, the connective element can be a multiconductor cable.
1. Spectacles comprising:
a temple;
a frame front;
a hinge connecting the temple to the frame front;
an electronics module disposed in the temple;
an electro-active lens held by the frame front; and
at least one flexible conductive link connecting the electronics module to the electro-active lens and configured to tolerate bending of the hinge,
wherein the at least one flexible conductive link is contained with a flexible conductive cable.
2. The spectacles of claim 1 , wherein the flexible conductive cable extends into the electronics module.
3. The spectacles of claim 1 , wherein the flexible conductive cable is connected to a lead that extends from the electronics module.
4. The spectacles of claim 1 , wherein the flexible conductive cable exits the temple and bypasses a connection between the hinge and the frame front.
5. The spectacles of claim 1 , wherein the flexible conductive cable connects to contact points on a rim of the spectacles.
6. The spectacles of claim 1 , wherein the flexible conductive cable forms a sealed connection from the electronics module to electrical connection points within an eye wire or rim of the spectacles.
7. The spectacles of claim 1 , further comprising:
a physically compliant insulator, disposed along at least a portion of an edge of the electro-active lens, to prevent liquid and/or moisture from penetrating the electro-active lens.
8. The spectacles of claim 1 , further comprising:
a physically compliant conductor, disposed along at least a portion of an edge of the electro-active lens, to provide an electrical connection between the electro-active lens and the at least one flexible conductive link.
9. The spectacles of claim 1 , wherein the at least one flexible conductive link provides a constant and flexible electrical connection to electronics in the electronics module.
10. Spectacles comprising:
a temple;
a frame front;
a hinge connecting the temple to the frame front;
an electronics module disposed in the temple;
an electro-active lens held by the frame front; and
at least one flexible conductive link connecting the electronics module to the electro-active lens and configured to tolerate bending of the hinge,
wherein the at least one flexible conductive link comprises a first flexible conductor and a second flexible conductor, and
wherein the first flexible conductor is rigid along a portion of its length.
11. Spectacles comprising:
a temple;
a frame front;
a hinge connecting the temple to the frame front;
an electronics module disposed in the temple;
