Claims

1. A head-mounted device, comprising:
a first optical sensor positioned to measure pulse data at a first arterial location that is a first distance from a heart;
a second optical sensor spaced apart from the first optical sensor and positioned to measure pulse data at a second arterial location that is a second, different distance from the heart; and
a controller wired to the first optical sensor and the second optical sensor and configured to determine blood pressure data from the pulse data measured by the first optical sensor and the second optical sensor.
2. The head-mounted device of claim 1, wherein one or more of the first optical sensor and the second optical sensor is positioned to measure pulse data at an angular artery.
3. The head-mounted device of claim 1, wherein one or more of the first optical sensor and the second optical sensor is positioned to measure pulse data at an occipital artery.
4. The head-mounted device of claim 1, wherein one or more of the first optical sensor and the second optical sensor is positioned to measure pulse data at a superficial temporal artery.
5. The head-mounted device of claim 1, further comprising a third optical sensor positioned to measure pulse data at a third arterial location that is a third distance from the heart.
6. The head-mounted device of claim 1, further comprising a motion sensor configured to monitor motion data of a wearer of the head-mounted device.
7. The head-mounted device of claim 6, wherein the controller is configured to determine correlation data regarding the blood pressure data and the motion data of the wearer.
8. The head-mounted device of claim 1, wherein the first optical sensor and the second optical sensor are configured to measure pulse arrival times at the first and second arterial locations, and the controller is configured to determine pulse transit time based on the pulse arrival times.
9. The head-mounted device of claim 8, wherein the controller is configured to determine changes in blood pressure based upon changes in the pulse transit time.
10. The head-mounted device of claim 1, wherein the head-mounted device comprises an eyeglass device.
11. A head-mounted device, comprising:
a first optical sensor positioned to measure pulse data at a first arterial location that is a first distance from a heart;
a second optical sensor spaced apart from the first optical sensor and positioned to measure pulse data at a second arterial location that is a second, different distance from the heart;
a motion sensor configured to monitor motion data of a wearer; and
a controller wired to the first optical sensor and the second optical sensor and configured to determine blood pressure data from the pulse data measured by the first optical sensor and the second optical sensor, and to determine correlation data regarding the blood pressure data and the motion data of the wearer.
12. The head-mounted device of claim 11, wherein one or more of the first optical sensor and the second optical sensor is positioned to measure pulse data at an angular artery.
13. The head-mounted device of claim 11, wherein one or more of the first optical sensor and the second optical sensor is positioned to measure pulse data at an occipital artery.
14. The head-mounted device of claim 11, wherein one or more of the first optical sensor and the second optical sensor is positioned to measure pulse data at a superficial temporal artery.
15. The head-mounted device of claim 11, wherein the first optical sensor and the second optical sensor are configured to measure pulse arrival times at the first and second arterial locations, and the controller is configured to determine pulse transit time based on the pulse arrival times.
16. The head-mounted device of claim 15, wherein the controller is configured to determine changes in blood pressure based upon changes in the pulse transit time.
17. The head-mounted device of claim 11, wherein the head-mounted device comprises an eyeglass device.
18. A wearable eyeglass device, comprising:
a first optical sensor positioned to measure pulse data at an angular arterial location on a head;
a second optical sensor spaced apart from the first optical sensor and positioned to measure pulse data at a superficial temporal arterial location on the head; and
a controller wired to the first optical sensor and the second optical sensor and configured to determine blood pressure data from the pulse data measured by the first optical sensor and the second optical sensor.
19. The wearable eyeglass device of claim 18, further comprising a motion sensor configured to monitor motion data of a wearer of the head-mounted device.
20. The wearable eyeglass device of claim 19, wherein the controller is configured to determine correlation data regarding the blood pressure data and the motion data of the wearer.
