Abstract: A method for placing a call intended for an enhanced network user on hold is disclosed. A calling party is enabled to select the type of information which is provided to the calling party while the calling party is on hold by using a Distributed Feature Network (DFN) architecture. The DFN includes a plurality of feature boxes with each feature box being created for the purpose of enabling a particular communication feature. A call intended for one of a group of ENUs is received by the DFN and an estimated hold time is determined for the call. The hold time is communicated to a caller associated with the call and the caller is provided with a list of options for information to be received by the caller while the caller is on hold. The caller's selection of a hold option is received by the DFN. A feature box is created for providing the caller with the selected information option, and the call is connected to the created feature box.

Abstract: A facility is provided to alert a subscriber whose telephone station set is connected to the Internet of a waiting call via the Internet connection. Specifically, a call that is waiting may be forwarded via the Public Switched Network to a services platform, which, in turn, establishes a connection to the subscriber using the Internet. The platform then notifies the subscriber of the waiting call via the Internet connection. The platform may then forward the telephone call to the subscriber via the Internet responsive to a subscriber request to do so with interrupting the subscriber's Internet connection.

Abstract: The provisioning of a multimedia application is enhanced by using a communications protocol which defines a number of different functions and which allows a multimedia application to be segmented into a plurality of logical blocks such that a user may enter a request characterizing one such function and, in response thereto, the system performs the function with respect to a particular one of the logical blocks. The underlying multimedia system is also enhanced by arranging it so that an application provider may interact with the system via a telecommunications network for the purpose of, for example, storing the application thereon and/or "debugging" the stored application.

Abstract: A method of analyzing a plurality of code segments to determine the similar static and dynamic features of the code segments compares the static and dynamic features of each of the code segments. Each code segment is comprised of one or more lines of program instructions. One or more predetermined static attributes are extracted from each code segment. Each code segment is then run so that the dynamic attributes of the code segment can be determined. The dynamic attributes are extracted from each code segment and a distance function is computed which is based on the extracted static and dynamic attributes for a given pair of code segments. The distance function produces a distance measurement which indicates the relative degree of similarity between the given pair of code segments.

Abstract: Methods are disclosed for finding maximal matches in data strings and for finding matches in parameterized strings, that is, strings containing symbols from more than one alphabet in which the symbols from one of the alphabet are treated as parameters. In general, such maximal matches are found by creating a suffix tree representing the data string, generating lists for each node in the tree indicating the left contexts of all suffixes associated with that node and reporting matches for pairs of suffixes having different left contexts. One method of finding parameterized matches is to substitute a common symbol for the symbols of the alphabet representing the parameters before creating the suffix tree and then discarding matches found for which the actual parameters are not consistent.

Abstract: A memory system contains one or more active storage elements. Each active storage element includes a memory element and a processing element associated with the memory element. The memory element contains microcode for implementing a specific function. A first bus connects the processing element to a host processor. A second bus connects the processing element to a peripheral.

Abstract: A cluster interface is generated which represents similarities of semantics between segments of code with respect to both the physical constructs of the code and the underlying operations performed by the code. The generated interface represents one or more code segments. Code segments to be analyzed are received by a computer system. Statistical internal information is extracted from each code segment. An external metric is generated which is based on the extracted statistical information. An interface display is created from the external metric which represents similarity relationships between the inputted code segments based on the extracted statistical information.

Abstract: A video system that captures telephone number data encoded into video signals transmitted over a video network to at least one display device is disclosed. Video signals are received that contain an escape sequence demarcating telephone number data. The system identifies the escape sequence, and captures the telephone number data. Upon command, dialing data corresponding to the telephone number data are transmitted over a telephone network to initiate a telephone call to the desired party.

Abstract: A radiotelephone wrist device includes a case having a transceiver and a strap attached to the case for fastening the device to a user's wrist. The strap has a top layer and a bottom layer. The top layer is attached to the bottom layer by a pivot mechanism which facilitates rotating at least a portion of the top layer with respect to the bottom layer. A microphone is located on the strap and electrically connected to the transceiver. A speaker is located at an end of the top layer of the strap and electrically connected to the transceiver. A first antenna is located in the bottom layer of the strap. A second antenna is located in the rotatable portion of the top layer of the strap.

Abstract: In a speaker verification system, a method of compensating for differences in speech samples obtained during registration and those obtained during verification due to the use of different types of microphones is provided by filtering at least one of the samples such that the similarities of the two samples are increased. The filtered sample is used within the speaker verification matching process. A two-way comparison is disclosed in which both a verification speech sample and a reference sample are filtered with nonlinear microphone characteristics such as carbon microphone characteristics. A four-way comparison is also disclosed in which patterns produced from unfiltered verification and reference samples and patterns produced from the filtered verification and reference samples are compared to identify a match. A score is determined for each comparison. The comparison having the best score is used to determine if a match has occurred.

Abstract: A radiotelephone wrist device includes a case having a transceiver and a strap attached to the case for fastening the device to a user's wrist. The strap has a top layer and a bottom layer in which the top layer is releasable from the bottom layer of the strap. A microphone is located on the strap and electrically connected to the transceiver. A speaker is located at an end of the top layer of the strap and electrically connected to the transceiver. A cradle for receiving the speaker is formed in the case. A sensor located beneath the cradle detects when the speaker is removed from the cradle.

Abstract: A method of regulating backpressure traffic in a packet switched network made up of a plurality of switching elements each having a local buffer memory identifies at least one switching element which succeeds at least one other switching element in a transmission path. The at least one succeeding switching element has a congested local buffer memory. A backpressure signal is transmitted to the at least one other switching element. Packets destined for the succeeding switching element are queued in the local buffer memory of the at least one other switching element. Next, it is determined when the occupancy of the local buffer memory for the other switching element has exceeded a predetermined threshold. In response to the exceeded predetermined threshold, the other switching element ignores the backpressure signal transmitted from the succeeding switching element and transmits the queued packets to the succeeding switching element.

Abstract: A method of prioritizing handoff requests in a cellular system is disclosed in which at least one handoff request for assignment of a communication channel is received from at least one mobile unit. A cutoff time for the handoff request is determined. The handoff requests are arranged in a priority queue based on the cutoff time associated with each handoff request. Available communication channels are assigned to the mobile units requesting handoff in the order of the queue.

Abstract: A method of reducing the size of an image of a document page selected rows and columns are eliminated from an image of a document page. The image is made up of a plurality of pixels which form rows and columns. Low information areas in the image are identified. An overall percentage of size reduction of the image is determined. Up to a predetermined maximum percentage of each low information area corresponding to the overall percentage of reduction is selectively removed so that the overall formatting of the document page is maintained.
