20100225914 | METHOD FOR MONITORING AND MEASURING OPTICAL PROPERTIES OF DEVICE IN POLARIZATION MAINTAINING FIBERS BY USING REFERENCE FIBER BRAGG GRATING AND FIBER COMPONENTS MANUFACTURED THEREBY - This invention provides a method for measuring and monitoring the state of polarization (SOP) of a polarization maintaining (PM) fiber and the like using a narrowband fiber Bragg grating (FBG) written on the same. The PM fiber therefore comprises a first narrowband reference FBG which is used as a reference to measure and monitor the SOP of the PM fiber. Due to the birefringence properties of the PM fiber, the reference FBG will generally reflect two narrowband spectra, each having a central wavelength; one in the slow axis and one in the fast axis. By measuring the intensity of the reflected spectra in each axis and by tuning the fiber with a polarization controller, it is possible to adjust the fiber to a predetermined SOP. After having adjusted the PM fiber to a predetermined SOP, it is possible to accurately measure the optical properties of a second grating, or of another optical device, according to the predetermined SOP. The method of the present invention can also be advantageously used for accurate measurement of reflectivity. | 09-09-2010 |

A plurality of base stations receive similar combinations of user signals from a plurality of users, compress the signals using quantization, and relay the signals over respective backhaul links to a processor in the network for decoding the signal. The processor determines suitable quantization noise levels for the backhaul links according to a weighted sum-rate maximization function for optimizing the quantization noise levels, subject to a backhaul sum capacity constraint on the backhaul links. The determined quantization noise levels are sent to the base stations, which then quantize the received combinations of user signals according to the quantization noise levels and relay the quantized signals to the processor. The quantization is according to a Wyner-Ziv coding or a single user compression algorithm that excludes statistical correlations between the user signals at the base stations. | 07-31-2014 |

20120192999 | METHODS AND SYSTEMS FOR PROCESSING MATERIALS, INCLUDING SHAPE MEMORY MATERIALS - A method for treating a material comprising: applying energy to a predetermined portion of the material in a controlled manner such that the local chemistry of the predetermined portion is altered to provide a predetermined result. When the material is a shape memory material, the predetermined result may be to provide an additional memory to the predetermined portion or to alter the pseudo-elastic properties of the shape memory material. In other examples, which are not necessarily restricted to shape memory materials, the process may be used to adjust the concentration of components at the surface to allow the formation of an oxide layer at the surface of the material to provide corrosion resistance; to remove contaminants from the material; to adjust surface texture; or to generate at least one additional phase particle in the material to provide a nucleation site for grain growth, which in turn, can strengthen the material. | 08-02-2012 |
