An apparatus includes an optical wave guide and a ferrule. The wireless communication device may then transmit said location data to a third party, such as an E-911 dispatch center or a provider of a commercial location-based service. A ferrule is provided on the front end side of the tubular housing and has a mechanism capable of attenuating, cutting-off, reflecting or absorbing a specific wavelength of light. The insulation layer exposed through the opening is removed while the semiconductor layer is used as a mask, and thereby a surface of a first semiconductor region is partially exposed. The second member is directly adjacent to the jamb member, and the support member is affixable to the wall. The at least one carrier member is selectively rotatable at least from a first position, wherein the cast part is generally retained in the at least one mold member, to a second position, wherein the cast part is generally free to fall or drop from the at least one mold member.
