| 20100208244 | FLASH LADAR SYSTEM - The present invention pertains in general to a single, integrated flash LADAR system and method. The system includes data processing hardware and software, a passive two-dimensional camera, a three-dimensional camera, a light source, and a common optical path. One or more star trackers can also be included. In addition, auxiliary components, such as an inertial measurement unit and a global positioning system receiver can be included. The system can be closely integrated with a critical algorithm suite that operates in multiple modes, in real-time to enable landing, docking, and navigation functions, such as Guidance, Navigation, and Control (GNC), Altimetry, Velocimetry, Terrain Relative Navigation (TRN), Hazard Detection and Avoidance (HDA), and dust penetration. | 08-19-2010 |
| 20130314699 | SOLAR RESOURCE MEASUREMENT SYSTEM - A solar resource measurement system captures an orientation-referenced image within a field of view of a tilted surface that includes a skyline, detects the skyline within the orientation-referenced image to establish a set of zenith angles as a function of azimuth angles associated with the skyline, and determines a solar resource for the tilted surface from the orientation-referenced image and the set of zenith angles as the function of azimuth angles that are associated with the skyline. | 11-28-2013 |

| 20100208245 | APPARATUS AND METHOD FOR A LIGHT DIRECTION SENSOR - The present invention provides a light direction sensor for determining the direction of a light source. The system includes an image sensor; a spacer attached to the image sensor, and a pattern mask attached to said spacer. The pattern mask has a slit pattern that as light passes through the slit pattern it casts a diffraction pattern onto the image sensor. The method operates by receiving a beam of light onto a patterned mask, wherein the patterned mask as a plurality of a slit segments. Then, diffusing the beam of light onto an image sensor and determining the direction of the light source. | 08-19-2010 |
