Resolving Multipath Components for Wireless Location-Finding
· Compatible with existing handsets · Does not rely on GPS or other satellite data · Accurate under challenging multipath conditions, such as indoor settings
· A more precise and accurate alternative to GPS that doesn’t require the integration of new hardware to determine location for cell users · Emergency 911, location sensitive billing, local broadcasting, indoor location finding, fleet management, mobile yellow pages
Researchers at UCLA have developed a robust positioning algorithm that is compatible with existing handsets. Instead of depending on external satellite signals, the proposed technique utilizes signals that are readily available in the network, thus eliminates the need to replace mobile handsets already in the market. Furthermore, the algorithm resolves multipath components rigorously, resulting in a robust outdoors and indoors positioning method.

Title: Method and apparatus for resolving multipath components for wireless location finding
Usefulness: Method and apparatus for resolving multipath components for wireless location finding
Summary: The method is useful for detecting interaction of CFTR proteins. (II) is useful for identifying a compound, especially a polypeptide or its biologically active fragment, antibody or its antigen binding fragment and a polynucleotide that facilitates interaction of CFTR polypeptides (claimed). The identified compound is useful for treating cystic fibrosis. (III) can be used to model wild-type CFTR protein dimerization, the effect of CF mutations on dimerization and to determine whether a particular mutation(s) of one or both the CFTR protein(s) will effect dimerization of the CFTR proteins and screen for drugs or compounds that can restore or enhance dimerization of CFTR proteins that contain mutations impacting dimerization.
Novelty: Detecting interaction of cystic fibrosis transmembrane conductance regulator (CFTR) polypeptides, useful for screening compounds for treating cystic fibrosis, comprises using yeast dual hybrid assay

Background Wireless location finding – obtaining the position information of a mobile subscriber – is becoming increasingly popular for mobile applications and social interfacing. Conventional positioning techniques depend on satellite signals, such as GPS data. As a result, the technique is applicable only to mobile handsets equipped with GPS receivers. In addition, the technique is not reliable in indoor environments, where satellite signals are adversely distorted due to the many obstacles present inside buildings (multipath effect).
