Abstract

Methods and devices are disclosed for collecting fingerprint and genetic information from an individual during a single collection session. A skin site is illuminated by direct imaging of the skin site using light reflected from the illuminated skin site. A cell of the individual, such as a skin cell, is retrieved from the collection surface.

Claims

1. A method of collecting fingerprint and genetic information from an individual during a single collection session, the method comprising:

illuminating a skin site positioned over and at least partially in contact with a collection surface;

obtaining an image of the skin site by direct imaging of the skin site using light reflected from the illuminated skin site; and

retrieving a cell of the individual from the collection surface.

2. The method recited in claim 1 wherein:

the collection surface is comprised by a single-use collection membrane at least partially transparent to the light; and

illuminating the skin site comprises directing light through the collection membrane to the skin site.

3. The method recited in claim 2 further comprising replacing the collection membrane in preparation for collecting fingerprint and genetic information from a second individual during a second collection session.

4. The method recited in claim 1 wherein the collection surface includes a chemical.

5. The method recited in claim 1 wherein the collection surface includes an adhesive property.

6. The method recited in claim 1 wherein the collection surface includes an abrasive property.

7. The method recited in claim 1 further comprising applying heat to the skin site.

8. The method recited in claim 1 further comprising applying pressure to the skin site.

9. The method recited in claim 1 further comprising moving the skin site relative to the collection membrane.

10. The method recited in claim 1 further comprising flowing air over the skin site.

11. The method recited in claim 1 wherein illuminating the skin site comprises illuminating the skin site under a plurality of distinct optical conditions.

12. The method recited in claim 1 wherein obtaining the image of the skin site comprises generating a topographic representation of the skin site.

13. The method recited in claim 1 wherein the cell comprises a skin cell.

14. The method recited in claim 2 further comprising placing the collection membrane on the skin site.

15. The method recited in claim 14 wherein the collection membrane comprises an adhesive strip wrapped around a body part.

16. The method recited in claim 14 wherein:

the skin site comprises a portion of a hand; and

the collection membrane is comprised by a glove or finger cot.

17. The method recited in claim 14 wherein:

the collection membrane comprises a marking; and

obtaining an image of the skin site comprises obtaining an image of the marking

18. The method recited in claim 14 wherein the collection membrane is substantially transparent to the light.

19. The method recited in claim 14 wherein:

the collection membrane comprises a conformal coating having a topography that substantially matches a topography of the skin site; and

obtaining an image of the skin site comprises obtaining an image of the conformal coating.

20. The method recited in claim 19 wherein the conformal coating is substantially opaque to the light.

21. A sensor comprising:

an illumination system disposed to direct light to a skin site of an individual;

a detection system disposed to receive light reflected from the skin site;

a single-use collection membrane adapted to contact the skin site during illumination of the skin site and to collect a cell from the individual, wherein the collection membrane is at least partially transparent to the light; and

a computational unit interfaced with the illumination system and with detection system, the computational unit having;

instructions to operate the illumination system to illuminate the skin site by directing the light through the collection membrane to the skin site;

instructions to operate the detection system to generate an image of the skin site by direct imaging of the skin site using light reflected from the illuminated skin site; and

instructions to maintain an association between the image and the cell.

22. The sensor recited in claim 21 wherein the collection membrane comprises an adhesive surface where it contacts the skin site.

23. The sensor recited in claim 21 wherein the collection membrane comprises an abrasive surface where it contacts the skin site.

24. The sensor recited in claim 21 wherein the instructions to operate the illumination system comprise instructions to illuminate the skin site under a plurality of distinct optical conditions.

25. The sensor recited in claim 21 wherein the instructions to operate the detection system to generate an image of the skin site comprise instructions to generate a topographic representation of the skin site.

26. The method recited in claim 21 wherein the cell comprises a skin cell.
