Abstract: A light-emitting system is provided which is removably attachable to headgear for personal illumination to enhance visibility of the user to others. The light-emitting system includes a housing that defines a receiving aperture and is configured to surround a portion of the headgear when the light-emitting system is removably attached to the headgear for use. The light-emitting system further includes at least one lens and a plurality of lighting elements coupled to the annular housing which are configured to selectively generate a halo or at least a partial halo of light that radiates outwardly away from the annular housing through the at least one lens to provide enhanced personal illumination.

Abstract: An optical waveguide fiber comprises: (a) a core with a refractive index profile having, a radius, an alpha and a relative refractive index characterized by delta% that varies along the radius; (b) at least one cladding surrounding the core; wherein the alpha is less than 2.5, peak refractive index delta % is between 0.34% and 0.4%, the relative refractive index is less than 0.01% for all radii greater than 7 pm, and this optical waveguide fiber has a mode field diameter MFD at a wavelength of 1310 nm of no more than 9.54 ?m, and attenuation less than: (a) 0.329 dB/km at a wavelength of 1310 nm, (b) 0.290 dB/km at a wavelength of 1383nm, (c) 0.255 dB/km at a wavelength of 1410 nm, and (d ) 0.189 dB/km at a wavelength of 1550 nm.

Abstract: An improved method of making a larger map from individual 7.5 minute digital line graph (DLG) data is described herein. The process is fully automated and performed by a computer with minimal human interaction required. This eliminates errors and produces a more accurate final map product. The method includes conversion of the raw DLG data files into ARC/INFO format, locating the border arcs of each individual data set, edgematching the individual map data sets, and joining the data sets into a single, large map coverage. Any node along the border arc which cannot be automatically edgematched is noted in a special error file. A geographer then matches the unmatched edges which contain an error in the input data. A large map product is available as the product of the process.
