20100296611 | DOWNLINK PREAMBLE PROCESSING TECHNIQUES FOR INITIAL ACQUISITION - An apparatus, system, method, and article for downlink (DL) preamble processing for initial acquisition are described. The apparatus may include an autocorrelator node to determine an autocorrelation response of samples and to detect a downlink preamble based on the autocorrelation response. The samples may include a periodic sequence having two or more periods. The apparatus may include a frequency domain matched filter processing node to perform downlink preamble recognition based on a maximum peak of a frequency domain matched filter response and on an index of the downlink preamble. Other embodiments are described and claimed. | 11-25-2010 |
20110280188 | PRE-CODING METHOD FOR SPATIAL MULTIPLEXING IN MULTIPLE INPUT AND OUTPUT SYSTEM - The present invention relates to a pre-coding method for spatial multiplexing, comprising the steps of: performing a beam search for beam forming with a receiver device equipped with multiple antennas to perform pre-coding for spatial multiplexing in a transmitter device equipped with multiple antennas; transmitting a first packet including at least one or more training sequences to the receiver device after completion of said beam search; receiving, from the receiver device, a second packet including feedback information for pre-coding, determined in the receiver device by using the training sequences; and performing pre-coding for spatial multiplexing, onto the data stream to be transmitted to the receiver device, by using the pre-coding matrix calculated on the basis of the feedback information. | 11-17-2011 |

20080310526 | Method, device, and apparatus for multi-stream multi-band transmission - A transmitter may include a set of stream groups, each including two or more streams producing a set of orthogonal frequency division multiplexed (OFDM) stream-symbols and a coding unit interleaving the stream-symbols into an interleaved signal. An input bit multiplexer may route an input data signal to be divided among each of the streams. An inverse fast Fourier transform unit may operate on a combined signal formed from interleaving the interleaved signals from each stream group. Each stream may include for example a baseband signal processor producing the OFDM stream-symbols. | 12-18-2008 |

20090052566 | METHOD FOR CHANNEL ESTIMATION USING RECURSIVE FILTERING AND MULTICARRIER RECEIVER WITH INTERFERENCE-AWARE DEMODULATION - Embodiments of a multicarrier receiver with interference-aware demodulation and methods for channel estimation using recursive filtering in wireless networks are generally described herein. Other embodiments may be described and claimed. In some embodiments, orders of a recursive filter are allocated to track a main channel and one or more interfering channels to generate channel estimates. | 02-26-2009 |
20100150079 | METHOD AND APPARATUS FOR SUPPRESSING CO-CHANNEL INTERFERENCE - System and method for interference reduction in a broadband wireless access (BWA) network are disclosed. A mobile station performs a recursive process to update channel estimates of interfering channels on a symbol-by-symbol basis for use in canceling interference from data subcarriers received through two or more antennas. | 06-17-2010 |

20140037645 | DIAGONSIS AND TREATMENT OF AUTOIMMUNE DISEASES BY TARGETING AUTOIMMUNE-RELATED B CELLS ("ABCS") - The present invention is directed to methods of diagnosis and treatment of autoimmune diseases based on the identification of a novel population of B cells known as Autoimmune- or Age-related B cells (“ABCs”). These cells express the CDI Ic cell surface protein and exhibit a unique gene expression profile. The ABCs increase in numbers in subjects that are prone to developing autoimmune diseases or in healthy individuals, particularly females, as they age. Accordingly, the present invention includes methods and kits for diagnosis of autoimmune diseases based on the detection of the ABCs before overt symptoms of the disease become detectable. The present invention also includes methods of treatment of autoimmune diseases by targeting the ABCs, as well as methods for assessing the efficacy of treatments of autoimmune diseases. | 02-06-2014 |

20140164100 | SYSTEM AND METHOD FOR PROVIDING RECOMMENDATIONS - A computerized recommender system and an associated computer-implemented method, which accumulate and analyze the information about various marketing actions for promoting brands as well as information about the subsequent brand performance within media channels. The channels include, but are not limited to web, blogs, social networks, search engines, contextual ad networks, email campaigns, and other promotional activities. Additional media channels can be added into the recommender system. The described recommender system enables the marketers to obtain custom advice for a given brand as to what should be the next most effective marketing actions to promote the brand. | 06-12-2014 |

20090244887 | LED-Based Incapacitating Apparatus and Method - Apparatus and method for using a light source to incapacitate a subject by a pattern of temporal flashing and/or color flashing of the light source. The light source is preferably an array of light emitting diodes. A rangefinder may be used to control the light output from the light source to avoid exposing a subject to light energy beyond a maximum permissible exposure threshold. | 10-01-2009 |
