Abstract

Various examples of an apparatus for mounting a camera on a vehicle are disclosed. An apparatus comprises a first portion of a first material with a first end configured for attaching to a camera and a second end configured for mounting to a vehicle. The apparatus is configured to maintain the camera in a substantially calibrated position. A second portion of a second material is coupled to the first portion, wherein the second material is capable of deforming upon an impact to the apparatus and returning the apparatus to the calibrated position upon exposure to an energy source. In another example, the apparatus is constructed entirely of the second material.

Claims

1. An apparatus for mounting a camera on a vehicle comprising:

a first portion of a first material with a first end configured for attaching to a camera and a second end configured for mounting to a vehicle, wherein the apparatus is configured to maintain the camera in a calibrated position; and

a second portion of a second material coupled to the first portion, wherein the second portion is a selectively weakened form so that the second portion deforms prior to the first portion in response to an impact, wherein the second material is capable of;

deforming upon an impact to the apparatus; and

returning the camera to the calibrated position upon exposure to an energy source.

2. The apparatus as in claim 1, wherein the second material is a shape memory metal.

3. The apparatus as in claim 1, wherein the second portion is less than 10% of a length of the first portion.

4. The apparatus as in claim 2, wherein the first material is the same as the second material.

5. The apparatus as in claim 4, wherein the first portion and the second portion are in a shape of one of two S-curves in non-coincident planes, a twisted ribbon and a three dimensional space-filling curve.

6. An apparatus for mounting a camera on a vehicle comprising:

a first portion of a first material with a first end configured for attaching to a camera and a second end configured for mounting to a vehicle, wherein the apparatus is configured to maintain the camera in a calibrated position; and

a second portion of a second material coupled to the first portion, wherein the second portion is coated and the coating visibly crazes in response to an impact;

wherein the second material is capable of;

deforming upon the impact to the apparatus; and

returning the camera to the calibrated position upon exposure to an energy source.

7. An apparatus for mounting a camera on a vehicle comprising:

a first portion of a first material with a first end configured for attaching to a camera and a second end configured for mounting to a vehicle, wherein the apparatus is configured to maintain the camera in a calibrated position; and

a second portion of a second material coupled to the first portion, wherein the first portion includes a first feature that aligns with a second feature on the second portion;

wherein the first feature and second feature are not aligned in response to an impact wherein the second material is capable of;

deforming upon the impact to the apparatus; and

returning the camera to the calibrated position upon exposure to an energy source.

8. The apparatus as in claim 7, wherein the first feature is an arrow and the second feature is an arrow.

9. An assembly for a camera mounting comprising

a camera;

a bracket comprising;

a first portion with a first end for fastening to the camera and a second end for mounting to a vehicle;

a second portion in a predetermined form coupled to the first portion, wherein the second portion is a selectively weakened form so that the second portion deforms prior to the first portion in response to an impact;

wherein the second portion is capable of;

deforming upon the impact to the apparatus; and

returning to the predetermined form upon exposure to an energy source.

10. The assembly as in claim 9, wherein the first portion is a rigid material and the second portion is a yielding material.

11. The assembly as in claim 9, wherein a field of view of the camera changes in response to the impact.

12. The assembly as in claim 9, wherein the second portion is coated and deformation of the second portion is determined when the coating is crazed.

13. The assembly as in claim 9, further comprising:

a shield for protecting the camera from the energy exposure during the reforming of the second portion.

14. The assembly as in claim 9, wherein the second portion is a shape memory metal.

15. The assembly as in claim 14, wherein the first portion is the same material as the second portion.

16. The assembly as in claim 15, wherein the first portion and the second portion are in a shape of one of two S-curves in non-coincident planes, a twisted ribbon and a three dimensional space-filling curve.

17. A method of configuring a camera assembly for a vehicle comprising:

fastening a camera on a first end of a bracket;

affixing a second end of the bracket to a vehicle;

wherein the bracket comprises a portion between the first end and the second end with a shape memory material in a predetermined form;

calibrating the camera based on the fastened position of the camera;

determining the camera is no longer in the calibrated position in response to the shape memory material no longer being in the predetermined form; and

exposing the shape memory material to an energy source such that the shape memory material returns to the predetermined form.

18. The method as in claim 17, wherein determining the camera is no longer in the calibrated position comprises an optical method of viewing the alignment of the first end of the bracket with respect to the second end of the bracket.

19. The method as in claim 17, further comprising:

impacting the camera assembly;

wherein the shape memory material is preferentially deformed in response to the impact.
