| 20090116753 | Authenticating and identifying objects using nanoparticles - Apparatus, system, and method to authenticate and identify objects using nanoparticles are described herein. In one embodiment, a computer-readable storage medium includes executable code to: (1) derive an index based on an authentication image of a marking; (2) select a reference image of the marking based on the index; (3) compare the authentication image with the reference image to determine whether the authentication image matches the reference image; and (4) produce an indication of authenticity based on whether the authentication image matches the reference image. | 05-07-2009 |
| 20090095341 | Solar Modules With Enhanced Efficiencies Via Use of Spectral Concentrators - Described herein are solar modules including spectral concentrators. In one embodiment, a solar module includes an active layer including a set of photovoltaic cells. The solar module also includes a spectral concentrator optically coupled to the active layer and including a luminescent material that exhibits photoluminescence in response to incident solar radiation. The photoluminescence has: (a) a quantum efficiency of at least 30 percent; (b) a spectral width no greater than 100 nm at Full Width at Half Maximum; and (c) a peak emission wavelength in the near infrared range. | 04-16-2009 |
