International Classification:

H04B 7/185
H04B 7/00

US Classification:

455522, 370318

Abstract:

Systems and methodologies are described that provide techniques for performing adjustments for delta-based power control and interference management in a wireless communication system. A terminal can utilize one or more delta-based power control techniques described herein upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed through open-loop projection, based on which transmission resources such as bandwidth and/or transmit power can be increased or decreased to manage interference caused by the terminal. A delta value, other feedback from the terminal, and/or indications of interference caused by the terminal can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.

International Classification:

C12Q 1/68
C12N 15/87

US Classification:

435006000, 435455000

Abstract:

The invention provides a novel expression cloning technique referred to as a matrix analysis of gene expression in cells (MAGEC) that allows for the indexed introduction, and analysis of nucleic acids in a host cell. While normally one takes cells attached to a surface followed by contacting the cells with heterologous DNA under conditions favoring the uptake of the heterologous DNA, the present invention, in sharp contrasts, proposes affixing (depositing) a nucleic acid-containing mixture onto a suitable surface and thereafter contacting suitable host cells (target cells) with the DNA-containing markings under conditions favoring uptake by the cells of the heterologous expression vector comprising a the target nucleic slide acid molecule. The method enables one to further characterize the gene product(s) of a known gene and unknown in a high-throughput assay format. It essentially allows for the identification of a gene based upon the function of its gene product.

International Classification:

H04J 11/00
G06F 17/14

US Classification:

370210, 708404

Abstract:

In embodiments, a wireless receiver employs a hardware-based Fast Fourier Transform (FFT) engine controlled by firmware. The FFT engine executes tasks stored in a task list. Each task is associated with a different portion of a signal, for example, one or more Orthogonal Frequency Division Modulated (OFDM) symbols. Each task may include configuration information for the FFT engine for configuring the engine to process the associated portion of the signal, a pointer to the portion to be processed, and another pointer to the memory for storing the output. The task list may be firmware controlled. Division of the FFT into a configurable hardware part driven by firmware to read and execute the tasks in the task list may speed up the FFT process and make it more flexible. A hardware beacon sorter may be coupled to the FFT engine to sort the sub-carriers according to their energies.

US Classification:

424 943, 435188

Abstract:

This invention relates to treatment of von Willebrand Disease by administration of Factor VIII muteins that are covalently bound, at a predefined site that is not an N-terminal amine, to one or more biocompatible polymers such as polyethylene glycol. The mutein conjugates retain FVIII procoagulant activity and have improved pharmacokinetic properties in subjects lacking von Willebrand Factor.
