20110206054 | DATA SESSION HANDLING - A method and apparatus to transfer a data session from one device connected to a residential gateway to another. The transfer is completed within the residential gateway, without routing data through the service provider's network. In one embodiment, a native address of a communication device engaged in an active data session is stored in a memory as a temporary device address. A session address in memory is set equal to the stored temporary device address and the temporary device address is associated with the session address in memory. When a request to transfer the data session to another device is received, the temporary device address in memory set to the native address of the new communication device and the session history is sent to the new device. Any new data received in the session, intended for the original device, is routed by a data session handling engine to the new communication device. | 08-25-2011 |
20110158364 | CLOCK SYNCHRONIZATION FOR A WIRELESS COMMUNICATIONS SYSTEM - Clock synchronization for a wireless communication system is described. The communication system utilizes a server with a radio coupled to receive a radio frequency (RF) signal and a clock interface to receive a reference clock signal. The server includes a network interface configured to receive, from a base station, a time that the RF signal was received at the base station. The server further includes a processing device configured to determine when the RF signal was transmitted and a location of the base station, and configured to calculate clock offset value representative of a time to delay a local clock signal at the base station to synchronize the local clock signal at the base station with the reference clock signal. | 06-30-2011 |
20100246413 | TRANSMISSION LINE SIMULATOR - A method and apparatus to simulate a length of telecommunications line. One or more bi-directional constant input impedance low pass or pole/zero filters are coupled in series with an attenuator to simulate a length of telecommunications line. The one or more filters are used to approximate the transfer function of the length of telecommunications line. | 09-30-2010 |
20100244983 | CONSTANT IMPEDANCE FILTER - A method and apparatus to provide a bi-directional constant impedance filter. Embodiments include electric networks which give filter responses while presenting a constant impedance to a signal received at either an input or an output port for a plurality of frequencies. | 09-30-2010 |
20100239265 | CARRIER CURRENT COMMUNICATION SYSTEM WITH INFRARED RECEIVER - Embodiments of a method and apparatus are described to transmit a data signal from a power supply unit, over existing direct current (DC) power transmission lines, to a residential gateway which includes an infrared (IR) receiver designed to receive optical signals. In one embodiment, the IR receiver is configured to receive a carrier current communication signal from the power supply unit over a pair of copper wires coupled to the IR receiver. The carrier current communication signals may be encoded by a transmission encoding logic circuit using pulse position modulation techniques. The received carrier current communication signals may be demodulated and decoded to reproduce an input data stream. | 09-23-2010 |
20100113067 | CELL NOTIFICATION - A system and method for enabling an access point to determine that a mobile device has crossed a wireless coverage area boundary associated with the access point and select, for transmission to the mobile device, an audible notification indicating the mobile device has crossed the wireless coverage boundary associated with the access point, wherein the audible notification is stored at the access point in compressed form, prior to determining the mobile device has crossed the wireless coverage area boundary. | 05-06-2010 |
20100113006 | CELL CALIBRATION - A system and method for enabling an access point to transmit a pilot signal to a mobile device operating in a specified location until a pilot signal acknowledgement is received from the mobile device indicating the pilot signal was detected at the specified location. The system and method further enabling the access point to automatically set an operational power level for the pilot signal based on a power level at which the pilot signal was being transmitted when the pilot signal acknowledgement was received. | 05-06-2010 |
20090086799 | DUAL-BAND LINE INTERFACE CIRCUIT CAPABLE OF MULTI-BAND COMMUNICATION - In an embodiment, a DSL communication device comprising a line interface circuit is disclosed. The line interface circuit includes a hybrid circuit to interface the communication device to a communication line, a lowpass transmit filter to pass signals in a first frequency band, and a highpass transmit filter to pass signals in a second frequency band, where the second frequency band is higher in frequency than the first frequency band. The outputs of the highpass and lowpass filters are coupled in parallel to the communication line. The lowpass and highpass filters as well as the low and highpass transformers are optimized for their frequency bands. Further, the edges of the low and high frequency bands are sufficiently separated to reduce interference from the other frequency band. These factors, in part, allow a multiple tone communication device to be capable of operating in multiple modes of operation with multiple DSL varieties. | 04-02-2009 |
