Abstract: A computer system includes an input device (210) and at least one processor (205). The processor receives (600) an electronic document that includes data representing a telephone number. The processor further receives input via the input device selecting (615) a telephone number from the electronic document.

Abstract: A method, a node and a machine-readable medium are provided for dynamically adjusting a beam of an adaptive antenna array (302). A receiving node (101) receives, via a group of antenna array elements (302), a signal from a transmitting node (101). Each received signal from the antenna array elements (101) is digitized and recorded. K+1 output signals are generated from the recorded digitized signal. The k+1 output signals are generated by applying each of a group of weight sets to the recorded digitized signal. Each of the weight sets corresponds to a different one of k known neighboring nodes (101) and a weight set for generating an omnidirectional propagation pattern. Which one of the k+1 output signals to process is determined. The determined one of the k+1 output signals is processed and the packet encoded in the determined one of the k+1 output signals is decoded.

Abstract: A system adjusts audio levels so as to maintain a constant perceived audio level at a user's location. The system includes a sensor (110) and an audio device (120). The sensor (110) receives a first audio signal, receives at least one data packet (1000) comprising a second audio signal, determines whether a difference between an average volume level of the first audio signal and the second audio signal exceeds a threshold value, generates a response data packet (1200) including a volume adjustment command when the difference between the average volume level of the first audio signal and the second audio signal exceeds the threshold value, and transmits the response data packet (1200). An audio device (120) transmits the first audio signal, transmits the at least one data packet (1000) to the sensor (110), receives the response data packet (1200), and adjusts an audio level based on the response data packet (1200).

Abstract: A system permits a customer service agent to receive and listen to an audio recording from a caller on a voice device (110), and thereby prepare to support the caller before connecting directly with him/her. The incoming call may originate on a public telephone network (120), and be received by a system (100). The system (100) may include one or more of an automatic call distributor/private branch exchange (130), a voice response unit (140), and a computer telephone integration server (160), and possibly a data device (180). The caller may be prompted to provide an audio message concerning the nature of the telephone call. Before being connected to the caller, the service agent may be provided with the audio message from the caller, possibly via the data device (180). After listening to the caller's previously recorded audio message and preparing to assist the caller, the agent and caller may then be directly connected together.

Abstract: The present invention provides a method for determining the carrier that should be used for a particular AIN call. The following information is derived for each call: the originating calling party number, the terminating called party number, the originating LATA, the terminating LATA. Using these components, pre-defined tables are accessed that contain local calling plan information. These tables contain rate center and dial plan information that provides the local calling scope that is available to the originator of the call. Based on the information contained in the tables, the appropriate type of carrier for the call is selected and the call is routed using this carrier.

Abstract: Systems and methods for localizing the position of a wireless device using a plurality of coordinated highly directional or adaptive antennas to detect signals from the wireless device. Because of the directional nature and/or adaptive processing of the antennas, off-angle multipath signals resulting from reflection and scattering as the wireless signal propagates through a cluttered environment are rejected by the antennas and processing. As a result, the antennas pass primarily direct path signals from the wireless device to the location estimator. The time of arrival of the signal and the angle of arrival at each antenna are used to in the location estimator to calculate the position of the wireless device. Various robust inversion techniques may also be applied to the data to minimize the effect of residual multipath-corrupted detections. Furthermore, the systems and methods include specialized wireless devices that provide locating signals and signals related to the biological condition of their owner.

Abstract: Methods are provided for forming and operating mesh communications networks. A primary application of these methods would be for a network for interconnecting telephone central offices. Compared to current networks, a network based on these methods may provide higher resource utilization efficiency, greater provisioning flexibility, and robustness against a wider range of network failures. These methods may enable protection and restoration of service following a failure to be tailored to the requirements of particular data flows. Mesh networks based on these methods of this invention may be extended seamlessly across contiguous LATA so that the data flow between central offices in different LATAs would not need to be routed through a separate inter-LATA network and would not require long haul transmission lines.

Abstract: A system for visually representing user behavior within an interactive voice response (IVR) system of a call processing center generates a complete sequence of events within the IVR system for plural calls to the call processing center, the plurality of calls being recorded from end to end. A call flow of the IVR system is modeled as a non-deterministic finite-state machine, such that a start state of the finite-state machine represents a first prompt of the IVR system, other states of the finite-state machine represent subsequent prompts at which a branching occurs in the call flow of the IVR system, exit conditions are represented as end states, and transitions of the finite-state machine represent transitions between call flow states triggered by data inputted by a user or by internal processing of the IVR system. The complete sequences of events for the plural calls are provided to the finite-state machine to produce a two-way matrix of several counters.

Abstract: A system (800) improves a network designer's ability to analyze a data network having several routers. The system (800) accesses static routing information and/or open shortest path first route summarization information, determines an identity of a network prefix using the accessed information, and analyzes the data network using the determined identity. The network designer can use this determined identity for traffic analysis or modeling of the data network.

Abstract: An apparatus and method for monitoring the performance of an interactive voice response (IVR) system used by an automated call processing center generates logs of call activity, determines routing information from the logs, notes predetermined significant activity in agent-caller dialog portions of calls routed to an agent in the logs, and determines at least one quantity correlated to a true intention of callers. A performance model of the IVR system is generated from the logs. The logs, the routing information, the quantity correlated to the true intention of the callers, and the performance model are analyzed to determine a performance value of the IVR system, which is used to monitor the IVR system.
