Abstract

Systems, devices, and methods are disclosed for unlocking a vehicle. An example vehicle includes an ultraviolet keypad coupled to a window. The vehicle also includes a camera directed at the window, configured to capture a key press of the ultraviolet keypad and an iris of a person outside the vehicle. And the vehicle further includes a processor configured to detect the key press and iris, unlock the vehicle based on the detected key press, and modify a vehicle setting based on a profile corresponding to the detected iris.

First claim

What is claimed is:

1. A vehicle comprising:
an ultraviolet keypad coupled to a window;
a camera directed at the window, configured to capture a key press of the ultraviolet keypad and an iris of a person outside the vehicle; and
a processor configured to:
responsive to detecting the iris, activate the ultraviolet keypad;
unlock the vehicle based on the detected key press; and
modify a vehicle setting based on a profile corresponding to the detected iris.

2. The vehicle of claim 1 , wherein the ultraviolet keypad coupled to the window comprises a layer of ultraviolet reflective material positioned between two layers of glass.

3. The vehicle of claim 1 , further comprising an ultraviolet LED configured to illuminate the ultraviolet keypad, wherein capturing the key press comprises capturing light reflected off a user's finger.

4. The vehicle of claim 3 , further comprising a near-infrared (NIR) LED, wherein capturing the key press comprises capturing NIR light reflected off the user's finger.

5. The vehicle of claim 1 , wherein the processor is further configured to:
determine a lighting condition surrounding the camera; and
based on the lighting condition surrounding the camera, select a light source used to detect the iris.

6. The vehicle of claim 5 , further comprising a near-infrared (NIR) LED, wherein the processor is further configured to:
determine that the lighting condition surrounding the camera is below a threshold level; and
responsively select NIR light as the light source used to detect the iris.

7. The vehicle of claim 5 , wherein the processor is further configured to:
determine that the lighting condition surrounding the camera is above a threshold level; and
responsively select visible light as the light source used to detect the iris.

8. The vehicle of claim 1 , wherein the processor is further configured to:
detect the person in proximity to the window; and
responsively activate the camera.

9. The vehicle of claim 1 , wherein the camera is coupled to a door of the vehicle.

10. The vehicle of claim 1 , wherein the camera is further configured to:
capture the iris; and
responsive to the processor determining that the detected iris corresponds to an allowed profile, capture the key press.

11. A method comprising:
capturing, by a camera of a vehicle having a window, an iris of a person outside the window;
responsive to detecting, by a vehicle processor, the iris, activating an ultraviolet keypad coupled to the window;
capturing, by the camera, a key press on the ultraviolet keypad;
unlocking the vehicle based on the detected key press; and
modifying a vehicle setting based on a profile corresponding to the detected iris.

12. The method of claim 11 , wherein the ultraviolet keypad coupled to the window comprises a layer of ultraviolet reflective material positioned between two layers of glass.

13. The method of claim 11 , further comprising an ultraviolet LED configured to illuminate the ultraviolet keypad, wherein capturing the key press comprises capturing light reflected off a user's finger.

14. The method of claim 13 , further comprising a near-infrared (NIR) LED, wherein capturing the key press comprises capturing NIR light reflected off the user's finger.

15. The method of claim 11 , further comprising:
determining a lighting condition surrounding the camera; and
based on the lighting condition surrounding the camera, selecting a light source used to detect the iris.

16. The method of claim 15 , further comprising:
determining that the lighting condition surrounding the camera is below a threshold level; and
responsively selecting near infrared (NIR) light as the light source used to detect the iris.

17. The vehicle of claim 15 , further comprising:
determining that the lighting condition surrounding the camera is above a threshold level; and
responsively selecting visible light as the light source used to detect the iris.

18. The method of claim 11 , further comprising:
detecting the person in proximity to the window; and
responsively activating the camera.

19. The method of claim 11 , wherein the camera is coupled to a door of the vehicle.

20. The method of claim 11 , further comprising:
prior to capturing the key press; capturing the iris;
determining, by the processor, that the iris corresponds to an allowed profile; and
responsively capturing the key press.
