| Appl. No: | 16/992788 |
| Application Filed: | August 13, 2020 |
| Abstrakt: | A method, medium and system for auto-aligning displays of a head/helmet mounted display. The method, medium and system may provide for an auto-alignment of components of a headband, headgear, or a helmet. The method, medium and system may provide for a first sensor mounted to the helmet of a user and configured to communicate and transfer align with a vehicle comprising an inertial navigation system (INS). The method, medium and system may provide for display comprising a second sensor configured to communicate with the first sensor and transfer align the second sensor with the first sensor based on the transfer alignment of the first sensor with the vehicle. The method, medium and system may provide for wherein the first sensor and the second sensor comprise an inertial measurement unit (IMU). Further, the method, medium and system may also provide for the aligning of two displays on the head/helmet relative to each other in real time. |

| Claim: | 1. An apparatus for auto-alignment of components of a headband, headgear or helmet, the apparatus comprising: a first sensor mounted to a headband, headgear, or helmet and configured to communicate and transfer align with a display comprising a second sensor mounted to the headband, headgear, or helmet. |
| Claim: | 2. The apparatus of claim 1 , wherein the first sensor and the second sensor each comprise an inertial measurement unit (IMU). |
| Claim: | 3. The apparatus of claim 1 , wherein the display is a see-through, head mounted display (HMD). |
| Claim: | 4. The apparatus of claim 3 , wherein the display is configured to present at least one of symbols, icons, and imagery to a user. |
| Claim: | 5. The apparatus of claim 1 , further comprising: a vehicle comprising an inertial navigation system (INS) or IMU configured to communicate and transfer align with at least one of the first sensor and the second sensor mounted to the headband, headgear, or helmet. |
| Claim: | 6. The apparatus of claim 1 , further comprising: a second display comprising a third sensor configured to communicate and transfer align with at least one of the first sensor and the second sensor. |
| Claim: | 7. The apparatus of claim 6 , further comprising: a vehicle comprising an inertial navigation system (INS) or IMU configured to communicate and transfer align with at least one of the first sensor and the second sensor mounted to the headband, headgear, or helmet. |
| Claim: | 8. The apparatus of claim 6 , wherein the first and second displays comprise a see-through head mounted display (HMD) and configured to present at least one of symbols, icons and images on the first and second displays to a user in a binocular or biocular arrangement. |
| Claim: | 9. The apparatus of claim 6 , wherein the second sensor and third sensor compare the transfer alignment to the first sensor to determine when there is an error in the transfer alignment. |
| Claim: | 10. The apparatus of claim 7 , wherein the vehicle is an aircraft, and wherein an aircraft alignment reference is mounted to the aircraft for additional alignment of the first sensor to the aircraft. |
| Claim: | 11. A method for auto-alignment of components of a headband, headgear, or helmet, the method comprising: receiving a first signal from a first sensor mounted to the headband, headgear, or helmet; receiving a second signal from a second sensor mounted to the headband, headgear, or helmet; and transfer aligning the first sensor with the second sensor based on the first signal and the second signal; and wherein the first sensor and the second sensor comprise inertial measurement units (IMUs). |
| Claim: | 12. The method of claim 11 , wherein the second sensor is mounted to a display. |
| Claim: | 13. The method of claim 11 , wherein the first sensor receives a third signal from an inertial navigation system (INS) of a vehicle; and transfer aligning the first sensor with the INS. |
| Claim: | 14. The method of claim 11 , wherein additional sensors are mounted to the headband, headgear, or helmet and provide additional signals that are used to transfer align to the first sensor. |
