Abstract: A highly effective method for operating data processing equipment to achieve data compression with high coding and storage efficiency and a method and apparatus for fast data retrieval while preserving full information content of the source data. This compressing method was used to successfully reduce the U.S. Geological Survey Database from 9.4 gigabytes to 800 megabytes, a reduction of over 90%. The compression method is an iterative and recursive process. At each iteration a data element is read into a buffer and then the pair formed by the last two elements in the buffer is checked against the rest of buffer. If a match is found in the buffer, the second element of the data element pair is removed and the first element is replaced by an index that indicates the sequential location in the buffer when the matching pair is found. The search for a matching pair is then repeated using the last two elements now in the buffer.

Abstract: An innovative rule based method and system for creating test cases for the Year 2000 compliance testing of software systems is described. Using the method and system of the present invention, the user will first input information as rules relating to the business logic of the system. After obtaining the business logic, the system will transform input test cases into output test cases for the Year 2000 compliance testing. The term test cases, used in a broad sense here, refer to regression test cases written in any test automation languages, archive of test input/output data files, or snap shots of transactions captured using a recording tool. The system operates by first parsing the input files and based upon the business logic, it identifies date, time, or duration dependent variables or constants ("date dependent fields" collectively) in the input test cases. The system then substitutes risky dates, time, or duration for these fields in a manner which preserves the business logic.

Abstract: A method for managing communications between a service origination node and a plurality of serving nodes where the serving nodes are simultaneously active for a particular trigger to thereby generate a reply to the service origination node. The method includes the step of determining control options for each trigger indicative of service categories by capturing service interaction principles supplied by a serving node services expert acting as a mentor. The service interaction principles are based upon a requirement of executing service categories in each of the serving nodes for each trigger. The method also includes the step of controlling execution of each of the service nodes and the service categories for the particular trigger with reference to the control options to generate the reply.

Abstract: A service control processor includes a plurality of service feature processors each corresponding to selected telephone service, and a plurality of call processing records, each corresponding to a customer of a service provider. The customer call processing records specify services subscribed to by the caller. A feature manager processor manages call processing and the implementation and execution of services by managing the individual service feature processors. In an alternative embodiment, multiple feature manager processors are included, and a trigger manager selects between them in response to call processing triggers.

Abstract: Radio ports (RPs) in an unlicensed personal communications system adaptively, autonomously set their interference threshold and/or transmission power levels. This may be done by the RP measuring the signal level on each of the available channels and then setting the interference threshold and/or power level according to these measurements. In a preferred method, the interference threshold is determined by measuring the signal level on each channel, ranking the channels in order of measured signal level, and using these rankings to determine the threshold. The transmission power level may be set with reference to the adaptive interference threshold level. This level is determined by using the system and FCC power limitations and current conditions to provide a satisfactory transmission level.

Abstract: A heterojunction bipolar transistor based on the InP/InGaAs materials family and its method of making. An n-type collector layer, principally composed of InP is epitaxially grown on an insulating InP substrate by vapor phase epitaxy. The collector layer is then laterally defined into a stack, and semi-insulating InP is regrown around the sides of the stack to the extent that it planarizes with the stack top. The semi-insulating InP electrically isolates the collector stack. A thin base layer of p-type InGaAs, preferably lattice matched to InP, is grown over the collector stack, and an n-type emitter layer is grown over the base layer. A series of photolithographic steps then defines a small emitter stack and a base that extends outside of the area of the emitter and collector stacks. The reduced size of the interface between the base and the collector produces a lower base-collector capacitance and hence higher speed of operation for the transistor.

Abstract: A method for broadcasting movies within channels of a wide band network by breaking the communications path into a number of logical channels and breaking each movie up into a number of segments of increasing size. The first segment of each movie is the smallest segment is transmitted in sequence over the first logical channel and repeated. The second segment of each movie which is proportionately larger than the first segment of each movie is transmitted in sequence over the second logical channel and repeated. This is repeated for the total number of segments which equals the total number of logical channels. The segments are broadcast in such a way that, once the first segment is received at a client location, the subsequent segments are also received in time, so that the movie can be viewed continuously.

Abstract: An apparatus and method for handling international telephone numbers even in the presence of conflicting national numbering plans wherein the telephone numbers are parsed according to the nature of address of the number, such as international, national, or other. Based on this determination the remainder of telephone number is processed, including parsing the telephone number and executing error handling procedures.

Abstract: To support local number portability and service portability in a telephone network, a method and apparatus handle subscription and administrative service requests in a local service management system to maintain records at a service control point. The subscription requests include create, modify, and delete requests of records in the service control point. The administrative service requests include Numbering Plan Area (NPA) code split, mass change, and query and resend requests. The records at the service control point are accessible by switches via respective signal transfer points to determine the network addresses of the switches handling services and calls corresponding to a particular telephone number.

Abstract: A method and system provide a unique communication and protocol between an optical line termination device and a plurality of optical network units sitting at different distances from the optical line termination device. The OLT determines the distance between it and each ONU and then requests communications from the ONUs in ascending order from nearest to farthest. The OLT also determines a time delayed period between the nearest ONU and the farthest ONU and awaits that time delay period before initiating subsequent ONU communication with the ONUs.

Abstract: A direct wind coil winding head assembly for depositing coil windings directly onto a coil support mandrel, comprising wire feed means having an input and an output, the wire feed means adapted to receive a continuous length of wire at the input and to cause the wire to exit the output at a first rate, mandrel positioning means for dynamically positioning the coil support mandrel beneath the output and control means coupled to the wire feed means and the mandrel positioning means, the control means operable to cause the mandrel positioning means to dynamically position the coil support mandrel beneath the output such that the exiting wire is deposited onto the mandrel in a predetermined pattern, and further operable to control the wire feed means such that the first rate is substantially equal to a second rate of movement of the coil support mandrel relative to the output, whereby the wire is deposited onto the coil support mandrel with substantially no residual winding stresses.
