Assignee:

Integrated Telecom Express, Inc. - San Jose CA

International Classification:

H04B 138

US Classification:

375222

Abstract:

A device or interface driver is provided for permitting an operating system to utilize, configure and control a software modem having forward compatible and expandable functionality. In a preferred embodiment, the operating system is a Windows based system running on a host processing system such as a personal computer, and the modem is compatible with standards promulgated for ADSL. Conventional voice band modem control commands are also supported, so that the present invention for ADSL based modems is nevertheless compatible with existing modem applications programs. The new driver manages control information for configuring the bandwidth to be used in a data link established through a channel with an upstream transciever during an initialization process, and serves as a data pump for the software modem. The control information may be self-determined by a user of the host processing system or alternatively, automatically sensed, configured and monitored by such processing system.

707705, 707805, 715700, 715968

Abstract:

A schema parser may determine one or more datasets of a database schema, wherein the datasets include one or more fields from a data source and represents data corresponding to the one or more fields. An input handler may receive a selection of one or more of the datasets via an interface. A translation engine may provide operations for refining the data of the selected datasets into a result set via a query, wherein the operations may be determined based on metadata defining relationships amongst the data sources and fields. A query engine may provide a graphical query including operational flow indicators indicating a directional flow of the query from the selected datasets with the selected operation to the result set.

International Classification:

H04B001/38

US Classification:

375/219000, 375/222000

Abstract:

A high speed communications system is provided which uses a selectable, desirable portion of the total available bandwidth of a transmission channel. In a preferred embodiment, the invention is an ADSL compatible modem which selects a sub-set of the available downstream DMT sub-channels based on an evaluation of such sub-channels by appropriate signal processing circuitry. An analog front end (AFE) contains sub-band filtering causes an upstream transceiver to use only this selected number of available sub-channels for downstream data transmission. This reduces hardware costs and complexity while still preserving compatibility with applicable ADSL standards and providing a high speed data link. The target data rate of the modem can be further enhanced to the point of achieving fill protocol capability by increasing or upgrading the AFEs, and/or the signal processing circuitry in order to increase the number of processable transmitted downstream sub-channels.

Abstract:

A method and system are provided for web search customization and web site rating. The system receives user input web sites, stores the web sites in a database, and groups them into user-specified categories. The system further allows users to select one or more web sites for customizing web search and querying the preselected sites using user input keywords. The system further provides the users with options to query a plurality of search engines. All web sites stored within the system are rated in response to the user operations. Each web site has at least a global rating indicating the rating within the system, a category rating indicating the rating within a given category, and a keyword rating indicating the rating for a given keyword. The system provides the users with a list of recommended web sites based on the web sites' ratings.

International Classification:

G06F 15163

US Classification:

709233

Abstract:

A high speed modem is provided which targets the use of a selectable, desirable portion of the total available bandwidth of a channel for achieving a data rate which nevertheless far exceeds that of conventional voice-band modems. In a preferred embodiment, the invention is implemented in an Asymmetric Digital Subscriber Loop (ADSL), and the nominal data rate is achieved using an analog front end (AFE) with subband filtering which causes an upstream transceiver to use only a selected number of available sub-channels for downstream data transmission and allows slower sampling rate for the AFE. The data rate of the modem is increased in a multiplicative fashion through modular expansion of a bank of AFEs to increase the number of transmitted downstream sub-channels.

Abstract:

A high speed software modem is described which uses a selectable, desirable portion of the total available bandwidth of a transmission channel. In a preferred embodiment, the invention is implemented in a personal computer connected to an upstream transceiver through a channel supporting an Asymmetric Digital Subscriber Loop (ADSL) standard. The achievable target data rate of the modem is based on the capabilities of an analog front end (AFE) used in the modem, and a host processor within such personal computer. In particular, the modem AFE contains subband filtering which causes an upstream transceiver to use only a selected number of available sub-channels for downstream data transmission. The data rate of the modem is increased by upgrading the AFE or the host processor in order to increase the number of processable transmitted downstream sub-channels.
