Abstract: This invention uses a computer program to mine preexisting intelligent network data located in a variety of preexisting source intelligent network databases. The computer program either creates a new intelligent network database from parts of existing intelligent network databases or modifies an existing intelligent network database. The computer program replaces the current system's reliance upon manual data entry by data engineers to configure the operation of a new telecommunication switch or replace the software in a telecommunication switch that was damaged or requires a new intelligent network data configuration.

The impedance transforming device is determined at least as a function of respective impedance transformations of the impedance transforming devices.

Abstract: A jacket for a communication cable is made from a resin that has high aspect ratio filler materials, and possibly coupling agents, dispersed therein. The fillers and the coupling agents reduce the post-extrusion shrinkage of the jacketing compound such that the strength members used in the communication cable need have only negligible compressive stiffness.

Abstract: A clamp for clamping an electronic component to a circuit board. The clamp has a frame capable of deflection, a spacer structure, and fasteners. The spacer structure has a first and second spacer. One, or both, of the spacers have an opening through at least a portion the spacer in the location where the spacer is positioned over the component. The opening places most of the force of the clamp on the walls of the package of the component. The walls can withstand more force than the lid of the package of the component because the walls are more rigid. This allows the clamp to exert a larger force on the component without cracking the thin lid of the package. The frame has a top section whose central portion is capable of deflection.

Abstract: An intersubband semiconductor light source comprises a core region that includes a unipolar, radiative transition (RT) region having upper and lower energy levels, an injector-only (I) region disposed on one side of the RT region, and a reflector/extractor-only (R/E) region disposed on the other side of the RT region. The I region has a first miniband of energy levels aligned so as to inject electrons into the upper energy level, and the R/E region has a second miniband of energy levels aligned so as to extract electrons from the lower energy level. The R/E region also has a minigap aligned so as to inhibit the extraction of electrons from the upper level. A suitable voltage applied across the core region is effective to cause the RT region to generate light at a wavelength determined by the energy difference between the upper and lower energy levels. Low voltage operation at less than 3 V is described.

Abstract: A method and apparatus for determining an approximated solution to the partitioning of a two or greater dimensional array in an amount of time on the order of O(1). Given a desired maximum weight or a maximum number of partitions, an array of data is partitioned by determining a temporary division of the array of blocks such that each block has a weight of at least two times the desired maximum weight. Within each block, rectangles are determined which contain array elements greater than or equal to an arbitrary value corresponding to a guess at a maximum weight. From among these rectangles, a largest set of independent rectangles is determined, and partitions are defined based on the sides of the largest set of independent rectangles determined for each block. Select ones of the partitions may be deleted until a total number of defined partitions is equal to or less than a desired maximum number of partitions.

Abstract: In an optical communication system, the signal power level injected into each of one or more optical fiber spans is reduced so as to suppress undesired non-linear effects. This reduction in injected signal level is made possible by remotely pumped amplification in the spans that are affected.

Abstract: An adaptive postfiltering arrangement for decoding video images is disclosed wherein the postfilter parameters used to control the strength of the postfilter are computed by the encoder at the time the video images are encoded and are transmitted to the postfilter as side information contained in the video image bitstream. The postfilter removes distortions from decoded video images, derived as a result of DCT coefficient quantization errors produced when the image is compressed for transmission to a decoder, and is based on computation of signal-to-noise ratios (SNRs), of one or more components of encoded video images. Other information about image content, such as face location information, can also be included in the side information sent to the postfilter in the video image bitstream, to modulate the postfilter strength according to the image content.

Abstract: A wireless telecommunications system with a base station positioned on an airborne platform is provided. The system utilizes a ground-based wireless switching center which communicates via a microwave link with a plurality of airborne base stations positioned above a geographic area being serviced by the telecommunications system. The base stations are supported on an airborne platform having a propulsion system designed to maintain the platform and the base stations in position above the geographic area being serviced. Advantageously, the platform may be positioned in the stratonull which is generally very stable and is located above the troposphere, wherein weather variations occur.

Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen occurs when a computer graphic object represented by computer graphics, e.g., in front of, to the side, above, or below the video screen, undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, because such an object would disappear from view by the viewer. This limitation is overcome by having such an object be represented as video on the screen, rather than computer graphics. Thus, the computer graphics object “goes into the video” as video and remains visible to a viewer in front of the video screen, rather than becoming invisible because it is blocked from view by the video screen if it were to be generated at its proper location using computer graphic techniques.

Abstract: A method, apparatus, article of manufacture, and propagated signal, for setting up a call by receiving a value representing a power level for a cell, adjusting the value representing the power level for the cell based on congestion to produce an adjusted value, and setting up the call based on the adjusted value.

Abstract: An Asynchronous Transfer Mode (ATM) network comprising a plurality of ATM switches may be arranged so that it receives calls from Synchronous Transfer Mode (STM) switches that employ in-band signaling by first converting in-band signals received from an STM switch to an out-of-band signaling message and then transmitting the message to the ATM switch that will route the associated call toward its destination. At an interface which interfaces the ATM switch with the out-of-band signaling network, the contents of the received message are converted to a form suitable for presentation to the ATM switch. For example, the identity of the trunk over which the call will be routed from the STM switch to the ATM switch is converted to a virtual channel identifier.

Abstract: Model checking is applied to a hierarchical state machine (i.e., a state machine having at least one state (i.e., a superstate) that is itself a state machine) without first flattening the hierarchical state machine. In one embodiment, the model checking involves one or more or reachability, cycle-detection, linear-time requirements, and branching-time requirements analyses. For reachability analysis, in addition to keeping track of whether states have been visited, the algorithm also keeps track of the exit nodes for each superstate. Cycle-detection analysis has two phases: a primary phase in which target states are identified and a secondary phase in which it is determined whether identified target states are part of closed processing paths or loops. For cycle-detection analysis, the algorithm keeps track of (1) whether states have been visited during the primary phase, (2) the exit nodes for each superstate, and (3) whether states have been visited during the secondary phase.

Abstract: An improved conference telephone which permits the active loudspeaker and microphone in a communication circuit to be universally positioned relative to one another. In one form, the conference telephone includes a base having a base-mounted speaker and a handset having both a handset-mounted speaker and a handset-mounted microphone. The handset-mounted microphone has at least a first sensitivity level and a second sensitivity level which is less than the first sensitivity level. A controller responds to the selection of a conference-call mode to activate the base-mounted speaker and to set the sensitivity of the handset-mounted microphone at the first sensitivity level.

Abstract: A bend limiter/strain reliever is provided for maintaining optical fiber bend limits at exit portals of a optic fiber closure for the closure's entire range of motion, from being fully closed to being fully open. Bend limits are maintained as optical fiber is directed on paths through a closure exit portal between the closure interior and wire brackets on the closure exterior. Fibers are retained, organized and strain relieved by the bend limiter/strain reliever such that directed fiber is maintain at a minimum bend radius on such fiber paths. The curved surface of the bend limiter/strain reliever allows the closure to be accessed without excessive bending of so routed optical fibers. In this manner, optical signal degradation and/or total loss is avoided by limiting the bending of routed optical fiber to radii in excess of a predetermined minimum bend radius.

Abstract: An article and method including an optical fiber coupled to a microstructure which is easily manufactured. The microstructure is comprised of a plurality of layers including a receptacle layer and a movable layer. The optical fiber has a high reflectivity terminal end forming the non-movable layer. The receptacle layer has an opening aligned with the movable layer for receiving the terminal end of the optical fiber. The optical fiber is inserted into the opening and the receptacle layer and fixed in relation to the microstructure, so as to form cavity between the terminal end of the fiber and the movable layer of the microstructure. The movable layer is physically adapted for moving relative to the non-movable layer under the influence of an actuating force.

Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen is that when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, namely, any portion of the object that is no longer on the video screen disappears. To overcome this limitation, when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, such an object, or portion thereof, is made to continue to be visible to the user by representing it at the foreground location to which its trajectory was carrying it using computer graphic techniques, rather than video.
