Abstract: Combined echo and crosstalk cancellation is provided. Frequency domain adaptive filters are used to remove or reduce the effects of echo and crosstalk for a multi-channel and full-duplex communications system. Data from each transmit channel is buffered and converted to the frequency domain. The frequency domain data is multiplied by crosstalk coefficients to obtain a frequency domain correction signal for each channel. Adaptation of the crosstalk coefficients is based on correlations between the error signals and the data from each of the transmit channels. A single frequency domain transform engine, such as a Fast Fourier Transform engine, is employed for all calculations to save power and area.

Abstract: Hybrid frequency compensation is provided. Hybrid circuits are used to subtract the transmit signal from the receive signal in a full duplex communication system. Since the hybrid circuit and the main line driver are exposed to different loads, accurate subtraction is difficult to achieve. A frequency dependent network is used to match the loading seen by the driver and the hybrid. The compensation network can be based on active and/or passive components.

Abstract: The present invention effectively cancels echo, near-end crosstalk and far-end crosstalk. A FEXT canceller is placed at the transmitter rather than at the receiver according to an aspect of the invention. In some embodiment, a FEXT canceller can be placed at the receiver only or the combination of both ends. The FEXT canceller is continuously adapted with information sent back from a remote receiver and with data from a neighbor transmitter that causes the crosstalk at the remote receiver. This allows the FEXT canceller to quickly adapt to a change in crosstalk function or conditions with the surrounding environment, for example, aging, temperature, humidity, physical pressure, etc. In some embodiments, an adaptation control signal is sent back from the receiver to the transmitter by using an overhead bit in the frame format. In some embodiments, part of the FEXT canceller is built-in at the remote receiver.

The flash memory-based storage device provides a plurality of mechanisms to accommodate a number of flash memory cards. As the storage capacity of the flash memory cards is increased over the time, so does the flash memory-based storage device by replacing only the flash memory cards.

Abstract: A scheme that enables seamless roaming between the WLAN and the cellular carrier network by enabling a user that originates a call in the WLAN and happens to go outside the range of the WLAN to automatically switch over to the cellular carrier network without losing connection with the other party. This solution assumes that the mobile device has the capability to operate in at least two modes that include the WLAN mode and one of the cellular carrier modes, such as the GSM, IS-95 CDMA, IS-136 TDMA, and iDEN.

Abstract: A method for generating a presentation of a region-of-interest in an original image for display on a display surface, the method comprising: establishing a lens for the region-of-interest, the lens having a focal region with a magnification for the region-of-interest at least partially surrounded by a shoulder region across which the magnification varies to provide a continuous transition from the focal region to regions outside the lens; receiving a first signal for selecting the shoulder region; while receiving the first signal, receiving a second signal for selecting the focal region and for adjusting a position of the focal region relative to the shoulder region to define a degree and a direction of a folding of the focal region over the shoulder region for the lens; and, applying the lens to the original image to produce the presentation.

Abstract: A service is configured by provisioning the service for a facility on a network access device (NAD). The service endpoint is created in an operationally disabled state responsive to provisioning the service. A first network interface unit (NIU) is detected connecting to the facility. The first NIU has an identification code associated therewith. The service transitions to an operationally enabled state responsive to detecting the first NIU connecting to the facility. The identification code is associated with the facility. The first NIU is detected disconnecting from the facility. The service transitions to an operationally disabled state responsive to detecting the first NIU disconnecting from the facility. A second NIU is detected connecting to the facility. The second NIU has an identification code associated therewith. The identification code of the second NIU is compared with the identification code of the first NIU.

Abstract: A network-based navigation system includes a user interface and a computer server system that can access a map database, an actual imagery database and an advertisement database in order to provide visual route guidance information having virtual drive-thru advertisements integrated with actual imagery from along a physical route. The user interface permits a user to submit a request for navigation information, receive visual route guidance information in response to the request and initiate a drive-thru presentation of at least a portion of a route. The computer server determines at least one route from the map database based on the request from the user and provides route guidance information to the user interface in response.

Abstract: A modem for use in Digital Subscriber Line communications transmits and receives data over the local subscriber loop in common with voice information over the loop, while avoiding the need for voice/data splitters. The modem responds to disruptions associated with “disturbance events” such as on-hook to off-hook transitions and the like by rapidly switching between pre-stored channel parameter control sets defining communications over the loop under varying conditions. In addition to changing parameter control sets responsive to a disturbance event, the modem may also change transmission power levels and other system parameters such as frequency domain equalizer characteristics. Further, provisions are made for reduced bandwidth communications under selected conditions.

A method and a computer-readable storage medium are also described and claimed.

Abstract: Data is distributed among the channels of an asynchronous data subscriber loop (ADSL) communications system in accordance with an adaptive algorithm which from time to time measures the signal to noise ratio of the various channels and finds a margin for each channel dependent on achievement (where possible) of a given bit error rate and a desired data transmission rate. The margin distribution is achieved by augmenting the constellation signal to noise ratio to enhance computational efficiency and allow redetermination of bit allocation tables during transmission as necessary. Pairs of bit allocation tables are maintained at the transmitter and receiver and one table of each pair at the transmitter and receiver is updated while the other pair is in use for controlling communication.
