In a specific embodiment, the device has a support substrate having a surface region. The device has a thickness of photovoltaic material overlying the surface region of support substrate and having a predefined surface texture to facilitate trapping of one or more incident photons using at least a refraction process to cause the one or more photons to traverse a longer optical path within an inner region of the thickness of material according to a specific embodiment. In a specific embodiment the longer optical path is provided relative to a shorter optical path characteristic of a surface region without the predefined surface roughness. In a specific embodiment, the device also has a dimension of about one wavelength of visible light to about two microns characterizing the thickness of the photovoltaic material. | 03-19-2009 |

20110253579 | PRODUCT AND PACKAGE FASTENING APPARATUS AND METHOD - An apparatus for fastening a product to its package for shipment and display. The apparatus includes a key having a base, an inner pad and outer ring portions. The base includes two bridges supporting two pairs of living hinges, each of the pairs being connected to an outer ring portion. The outer ring portions are enabled to pivot between a position generally aligned with the inner pad and a position generally perpendicular to the inner pad so as to act as a handle to rotate the key. The inner pad supports a post and a pair of protrusions. Between the inner pad and the outer ring portions are openings for receiving a strip of stiff paper. After the key is inserted through the package and into the product, the key is rotated to cause an abutment of the protrusions with the product to fasten the product and package together. The strip is then inserted to prevent inadvertent rotation of the key. After purchase, a consumer may easily and quickly remove the strip, rotate the key and remove it from the product and the package to enable the product to be separated from the package, and the package and the key to be disposed. Multiple keys are used with multiple strips incorporated in a stiff paper panel. Each strip takes the form of a hole in the panel flanked by two strip tabs that connect to the key inserted through the hole of the strip. A reinforcing support may be placed between the panel and the package. | 10-20-2011 |

20150269737 | Multi-View Synthesis in Real-Time With Fallback to 2D from 3D to Reduce Flicker in Low or Unstable Stereo-Matching Image Regions - Multi view images are generated with reduced flickering. A first depth map is generated from stereo images by stereo-matching. When stereo-matching is poor or varies too much from frame to frame, disparity fallback selects a second depth map that is generated from a single view without stereo-matching, preventing stereo-matching errors from producing visible artifacts or flickering. Flat or textureless regions can use the second depth map, while regions with good stereo-matching use the first depth map. Depth maps are generated with a one-frame delay and buffered. Low-cost temporal coherence reduces costs used for stereo-matching when the pixel location selected as the lowest-cost disparity is within a distance threshold of the same pixel in a last frame. Hybrid view synthesis uses forward mapping for smaller numbers of views, and backward mapping from the forward-mapping results for larger numbers of views. Rotated masks are generated on-the-fly for backward mapping. | 09-24-2015 |
