Head worn computer display systems
Head-worn computers may include a rigid optical chassis mechanically configured to provide a stable optical mounting reference plane with an image source reference plane, a first image source mounted on the image source reference plane and configured to project a first image light from the stable optical mounting reference plane to a combiner positioned in front of a user's eye when the head-worn computer is worn by the user, an outer frame configured to hold the optical chassis such that, when worn by the user, the first image light is aligned with the eye of the user, and an arm rotatably mounted on the outer frame and adapted to be positioned on a user's ear, wherein the arm comprises a battery compartment and a wire connected to at least the first image source.
1. A head-worn computer, comprising:
a rigid optical chassis mechanically configured to provide a stable optical mounting reference plane with an image source reference plane;
a first image source mounted on the image source reference plane and configured to project a first image light from the stable optical mounting reference plane to a combiner positioned in front of a user's eye when the head-worn computer is worn by the user;
an outer frame configured to hold the optical chassis such that, when worn by the user, the first image light is aligned with the eye of the user; and
an arm rotatably mounted on the outer frame and adapted to be positioned on a user's ear,
wherein the arm comprises a battery compartment and a wire connected to at least the first image source.
2. The head-worn computer of claim 1 , wherein the combiner is see-through and is mounted on the stable optical mounting reference plane that reflects the first image light towards an eye of the user.
3. The head-worn computer of claim 1 , wherein the combiner reflects the first image light directly towards the eye of the user.
4. The head-worn computer of claim 1 , wherein the combiner indirectly reflects the first image light towards the eye of the user.
5. The head-worn computer of claim 1 , wherein the combiner reflects the first image light towards a curved partially reflective surface that reflects the first image light towards the user's eye.
6. The head-worn computer of claim 1 , wherein the combiner includes a notch mirror.
7. The head-worn computer of claim 1 , further comprising an outer lens mounted on the outer frame.
8. The head-worn computer of claim 7 , wherein the outer lens is user replaceable.
9. The head-worn computer of claim 1 , further comprising a second image source mounted on the rigid optical chassis and configured to project second image light from the stable optical mounting reference plane.
10. The head-worn computer of claim 1 , wherein a processor is mounted at a top opening of the optical chassis and a heat sink is mounted on top of the top opening and in thermal contact with the processor.
11. The head-worn computer of claim 1 , wherein the optical chassis comprises magnesium.
12. The head-worn computer of claim 1 , wherein the optical chassis comprises aluminum.
13. The head-worn computer of claim 1 , wherein the combiner is mechanically associated with the image source reference plane such that the image source projects the image light to the combiner based on the reference plane.
