International Classification:

H04B 3/46

US Classification:

375224, 375225, 375285, 375346, 370201, 455295, 455296, 455501, 455 631

Abstract:

Methods, apparatus and systems for dynamically controlling a digital communication system, such as a DSL system, collect information about digital communication lines in the system and adaptively and/or dynamically determine line and signal characteristics of the digital communication lines, including interference effects. Based on the determined characteristics and the desired performance parameters, operation of the digital communication lines is adjusted to improve or otherwise control the performance of the system. The collection and processing of information may be performed by a party that is not a user in the system. This independent party also may control operational characteristics and parameters of the system. The invention can be used to eliminate or reduce signal interference such as crosstalk that can be induced on communication lines in systems such as DSL systems. Specific iterative power allocation and vectored transmission techniques and apparatus are disclosed.

International Classification:

US Classification:

Abstract:

A method for generating radio frequency (RF) planning modeling data for an object. The method includes placing an RF signal source near the object and sequentially positioning a receiver at a plurality of locations around the object. At each of the locations, an indication is provided to the receiver that it is at a measurement location, and the receiver is allowed to detect a level of the RF signal produced by the RF signal source at the measurement location. In another aspect, an opening in an object is modeled as a virtual object that overlaps with the object and has a “negative attenuation” characteristic to cancel out the “positive attenuation” characteristic of the object.

International Classification:

F21V 33/00

US Classification:

362102, 362 96, 362101, 362318, 362577

Abstract:

This invention is a light baton for use in aquatic games, comprising a translucent baton body, end inserts at both ends of the baton body, an end insert connected to an inserted light-emitting module, holes in the translucent baton body, and arcuate convex protuberances on the outer surface of the translucent baton body; the holes in the translucent baton body allow water to flow in and surround the light-emitting module, with the change in air and water density causing the baton to sink in water, while the liquid has a refractive effect on the colorful lights from the light-emitting module; the colorful beams of light pass through and are refracted by the ripples in the liquid within the baton body to produce illumination, making the baton ideal for having fun in water.

Abstract:

The present invention relates to a straw cup with variable lights, primarily comprising of a set of light-emitting diodes surrounding the inside of the cup's straw, a circuit controller board, and power switch; when the power is activated, the liquid inside the straw's cup refracts and directs light, increasing the variation and brilliance of the twinkling lights and thus further increasing the variation of the straw cup's multicolored lights.

Abstract:

An object of the present invention is to provide a method for detecting cancer through identification of genes exhibiting characteristic behavior in the cases of cancer such as anaplastic thyroid cancer. The present invention provides a method for detecting cancer which comprises detecting canceration of a specimen using the amplification of a gene of the p12 region of chromosome 8 in the specimen as an indicator.

Abstract:

Incremental training data is used to supplement a trained model to provide personalized recommendations for a user. The personalized recommendations can be made by taking into account the user's behavior, such as, without limitation, the user's short and long term web page interactions, to identify item recommendations. A trained model is generated from training data indicative of the web page interaction data collected from a plurality of users. Incremental training data indicative of other web page interaction data can be used to supplement the trained model, or in place of the trained model. Incremental training data can be indicative of user behavior collected more recently than the data used to train the model, for example.
