20120105208 | TRANSPONDER SYSTEMS AND METHODS FOR RADIO-OVER-FIBER (RoF) WIRELESS PICOCELLULAR SYSTEMS - Transponder systems and methods for radio-over-fiber (RoF) wireless picocellular system are disclosed. One type of transponder system includes a RoF transponder used in combination with at least one radiation-reflector assembly to provide for enhanced antenna directivity of the transponder. Another type of transponder system is a transponder node assembly, wherein two or more transponders are integrated into a single assembly, thereby reducing cost while facilitating RoF wireless picocellular system deployment. Another type of transponder system provides one or more transponders in a RoF wireless picocellular system with radio-frequency identification (RFID) tags, and uses an RFID tag reader to locate and read information from the transponders, as well as to perform transponder mode selection. Another type of transponder system is directed to a tether cable assembly that includes a dispensible/retractable coiled tether cable housed in a protective housing for connecting the tether cable to a transponder. | 05-03-2012 |
20120275180 | Light Diffusing Fibers and Methods for Making the Same - Light diffusing optical fibers and methods for producing light diffusing optical fibers are disclosed. In one embodiment, a light diffusing optical fiber includes a core portion formed from silica glass and comprising a plurality of helical void randomly distributed in the core portion of the optical fiber and wrapped around the long axis of the optical fiber. A pitch of the helical voids may vary along the axial length of the light diffusing optical fiber in order to achieve the desired illumination along the length of the optical fiber. A cladding may surround the core portion. Light guided by the core portion is scattered by the helical voids radially outward, through the cladding, such that the light diffusing optical fiber emits light with a predetermined intensity over an axial length of the light diffusing optical fiber, the light diffusing optical fiber having a scattering induced attenuation loss greater than about 0.2 dB/m at a wavelength of 550 nm. | 11-01-2012 |
