Abstract: A method of providing security for network access radio systems and associated access radio security systems used with the systems. The method includes connecting an access radio having a radio link to a network; communicating between the access radio and a computer over the network using a ping application having ping commands and unique encrypted codes; and enabling operation of the access radio when the access radio is receiving ping commands. Typically, the access radio and the computer are nodes on the network and the network is a local area network (LAN). The ping application sends packets of information from the computer to the access radio and receives a response from the access radio. The ping application must be functioning (i.e., sending and receiving commands between the computer and the access radio) to enable the access radio to communicate via the radio link with a remote network.

Abstract: The present invention includes a method and apparatus for providing an e-help service over a network. The e-help service provides one or more action sequences, i.e., recommended courses of action, for specialized circumstances over a network, such as an Internet Protocol network. Subscribers subscribe to specific application areas, such as one or more application areas related to a subscriber's industry. The e-help service provider maintains information pertaining to application areas in one or more databases. When a user activates the e-help service, information corresponding to the present conditions of the user's circumstance is transmitted to the e-help service provider. The e-help service provider identifies one or more action sequences based upon a statistical analysis of the information received from the user and information stored in a database corresponding to the application area of the user.

Abstract: A method for cost-effective optical transmission with fast Raman tilt or other transient event control uses a combination of Erbium-doped fiber amplifiers (EDFAs) and Raman fiber amplifiers (RFAs), where EDFAs are used as the primary optical amplifiers to compensate the span loss while the RFA (advantageously a forward-pumped RFA) is used only in some specific spans with a feed-forward control circuit serving as a fast Raman tilt transient compensator, the RFA also serving as an optical amplifier. A long haul optical transmission system using feed-forward controlled RFA's periodically spaced along its length, for example, when add-drop multiplexing is used, makes full use of the economics of EDFAs and the fast tilt transient control capability of a RFA enabled by an adjustable speed feed-forward or feed-back control technique.

Abstract: A speech synthesis system can select recorded speech fragments, or acoustic units, from a very large database of acoustic units to produce artificial speech. The selected acoustic units are chosen to minimize a combination of target and concatenation costs for a given sentence. However, as concatenation costs, which are measures of the mismatch between sequential pairs of acoustic units, are expensive to compute, processing can be greatly reduced by pre-computing and aching the concatenation costs. Unfortunately, the number of possible sequential pairs of acoustic units makes such caching prohibitive. However, statistical experiments reveal that while about 85% of the acoustic units are typically used in common speech, less than 1% of the possible sequential pairs of acoustic units occur in practice.

Abstract: A method for use in an IMS VoIP Network provides for remote troubleshooting of a CPE problem. After receiving a customer complaint, customer care begins the troubleshooting process, collecting and compiling information to send to the test platform. The test platform constructs a SIP test call request instruction and sends it to the CPE. The process is repeated for a number of test calls. If there is no response from any of the test calls, it is concluded that the CPE is in trouble. The results are reported to Customer Care Center, which can use those results to take action to resolve the problem. In another embodiment, after failure of all of the test calls, another SIP instruction is sent to run diagnostics on the CPE. The diagnostic results are reported to Customer Care Center, which can take action based on those results to resolve the problem.

Abstract: A method of content adaptive encoding video is disclosed. The method comprises segmenting video content into segments based on predefined classifications or models. Examples of such classifications include action scenes, slow scenes, low or high detail scenes, and brightness of the scenes. Based on the segment classifications, each segment is encoded with a different encoder chosen from a plurality of encoders. Each encoder is associated with a model. The chosen encoder is particularly suited to encoding the unique subject matter of the segment. The coded bit-stream for each segment includes information regarding which encoder was used to encode that segment. A matching decoder of a plurality of decoders is chosen using the information in the coded bitstream to decode each segment using a decoder suited for the classification or model of the segment.

Abstract: A business process automation system architecture is used to isolate problems in a virtual private network access network. Codified rules and a rules based program are used to determine all equipment from a customer premises equipment to a VPN core access point equipment on a VPN access path and that is associated with a failure. The codified rules also govern the gathering of information on the equipment including determining whether the equipment supports automated diagnostics and the communication protocols used. Extended PING testing is done on the equipment and a status of the extended PING test, link status, line protocol status, and existing loop status is determined. Further testing is automatically run based on the codified rules and the status. The failure is then isolated to the CPE, a local exchange carrier, or a network provider.

If the source is the same as the content identifier, then the cache server caches the content item.

Abstract: An animation wireframe is modified with three-dimensional (3D) range and color data having a corresponding shape surface. The animation wireframe is vertically scaled based on distances between consecutive features within the 3D range and color data and corresponding distances within the generic animation wireframe. For each animation wireframe point, the location of the animation wireframe point is adjusted to coincide with a point on the shape surface. The shape surface point lies along a scaling line connecting the animation wireframe point, the shape surface point and an origin point. The scaling line is within a horizontal point.

Abstract: Disclosed are systems and methods for providing a spoken dialog system using meta-data to build language models to improve speech processing. Meta-data is generally defined as data outside received speech; for example, meta-data may be a customer profile having a name, address and purchase history of a caller to a spoken dialog system. The method comprises building tree clusters from meta-data and estimating a language model using the built tree clusters. The language model may be used by various modules in the spoken dialog system, such as the automatic speech recognition module and/or the dialog management module. Building the tree clusters from the meta-data may involve generating projections from the meta-data and further may comprise computing counts as a result of unigram tree clustering and then building both unigram trees and higher-order trees from the meta-data as well as computing node distances within the built trees that are used for estimating the language model.

Abstract: A system and method to provide content and call attributes for a destination phone number using a click-to-dial connection includes accepting a query, retrieving links to a document, and searching through cached data using the query to identify relevant or destination number information. If no match is found, the method continues with accessing the document identified by the link for identifying relevant number information and creating a click-to-dial icon to link to the relevant numbers included in the relevant phone number information identified by the query. Next, a popup box for content relevant to the click-to-dial icon and a click feature on the popup box are created to retrieve call destination attributes for viewing by a user. Further, computer instructions create at least one communication connection between two communication devices after viewing call destination attributes.
