Patent number: 5831995Abstract: The testing of a series of commands is enhanced using a multilevel approach that employs orthogonal arrays within orthogonal arrays. Specifically, an Orthogonal Array (OA) is applied within each operation and then re-applied across the different operations. Thus, the process initially applies an OA to an intra-operation covering the different combinations of command parameters associated with an operation. The process applies an OA to an inter-operations OA covering the combinations of all command parameters.Type: GrantFiled: October 23, 1995Date of Patent: November 3, 1998Assignee: Lucent Technologies Inc.Inventors: Philip E. Brown, Pramod Warty

Patent number: 5768359Abstract: A facility is disposed in a telecommunications network to provide an alternative to the conventional call waiting feature. More particularly, if a telephone call is placed to a subscriber while the subscriber's telephone station set is busy with another telephone call, then the facility notes that fact and terminates the new telephone call after advising the caller that the subscriber's station is busy. Thereafter, the facility places a telephone call to the subscriber and presents thereto at least the telephone numbers of the telephone stations that placed respective calls to the subscriber during the time that the latter's station was busy.Type: GrantFiled: November 17, 1994Date of Patent: June 16, 1998Assignee: Lucent Technologies Inc.Inventors: Anthony R.

Patent number: 5751824Abstract: To prevent particular transmission equipment from artificially increasing low level audio signals to a predetermined allowable level, such signals are first summed with a stabilization signal having a predetermined frequency to form a composite audio signal. Moreover, the stabilization signal has a level that prevents any increase in signal level that may be artificially imposed on the composite signal during the processing of the composite signal by the transmission equipment. Once the composite signal has been so processed, then the stabilization signal is removed therefrom and the original audio signal is outputted to associated transmission media.Type: GrantFiled: September 23, 1994Date of Patent: May 12, 1998Assignee: Lucent Technologies Inc.Inventor: Robert B. Pladek

Patent number: 5694540Abstract: The regression testing of a recompiled main software program is provided a facility which performs a limited regression test that has the same level of testing as if the main program were tested using an expanded regression test that tests virtually all of the software modules forming the program. More particularly, if an error is found in the main program it is documented in a modification request which a programmer thereafter uses to track down and identify the software module(s) that needs to be modified to deal with the error. At that point, the programmer modifies the identified software module and also designs a current test program to test the recompiled program to determine if the error has been corrected and that the modification does not affect some other aspect of the program. The modified module and test program are then associated with an identifier identifying the associated modification request.Type: GrantFiled: January 16, 1996Date of Patent: December 2, 1997Assignee: Lucent Technologies Inc.Inventors: James E. Humelsine, Moses M. Ling, Carl H. Olson, III, Pramod Warty

Patent number: 5668865Abstract: The detection of echo is enhanced using a coarse near-end speech detector at a Y-side of an echo canceler and using a more accurate near-end speech detector at the E-side of the echo canceler, such that the latter detector uses a representation of far-end speech and a threshold value to determine if the magnitude of the echo canceler output is larger than that of an echo signal only. If it is, and there is an absence of an indication of the presence of near-end speech from the coarse detector, then the more accurate speech detector adjusts the value of the threshold in a first direction, otherwise it adjusts the threshold in a second direction, to more "finely tone" such accuracy.Type: GrantFiled: February 26, 1996Date of Patent: September 16, 1997Assignee: Lucent Technologies Inc.Inventors: Donald Lars Duttweiler, Cheng Kim, Ying Get Tao

Patent number: 5649131Abstract: The invention is directed to a communications protocol which facilitates the exchange of interface information between a host processor and a terminal, such as a workstation, smart phone, portable computer, etc., by associating an object that is to be displayed on the terminal display with a particular identifier, and by associating input information entered in response to a user manipulating a displayed object with the associated object identifier, rather than the location of the displayed object. Accordingly, a host processor may specify relative rather than specific attributes for an object that is to be displayed on a terminal display, thereby leaving it up to the terminal to display an object in accord with its own capabilities.Type: GrantFiled: December 30, 1992Date of Patent: July 15, 1997Assignee: Lucent Technologies Inc.Inventors: Chaim M. Ackerman, Alan L. Glasser, Reuben Klein

Patent number: 5640683Abstract: A modulated backscatter communication system (e.g., an Electronic Shelf Label (ESL) system) includes a central node (e.g., a ceiling node) and one or more remote nodes (e.g., ESL tags). The central node transmits a downlink radio signal which is reflectively modulated at a remote node to produce a modulated reflected radio signal. At the remote node, a precise-frequency subcarrier signal is modulated with an uplink information signal to produce a modulated signal which is used to produce the modulated reflected radio signal. At the central node, the modulated reflected radio signal is received, detected and narrowband filtered to obtain the modulated subcarrier signal which is then demodulated to obtain the uplink information signal, with great immunity to close to carrier downlink radio noise and fluorescent light backscatter interference.Type: GrantFiled: July 17, 1995Date of Patent: June 17, 1997Assignee: NCR CorporationInventors: James Gifford Evans, R. Anthony Shober, Giovanni Vannucci, Stephen A. Wilkus

Patent number: 5583925Abstract: A facility is disposed in a telecommunications network which, advantageously, establishes a conference (N-way) call more efficiently than was done priorly. Specifically, a caller may establish a N-way call by dialing a code representing a sequence of speed dial codes respectively associated with the telephone numbers of the conferees that will be involved in the N-way call, rather than dialing each such telephone number. The facility, responsive to receipt of the dialed code, identifies the associated sequence of speed dial codes and places a call to each of the telephone numbers associated with those codes. In this sense, one code represents a plurality of telephone numbers.Type: GrantFiled: March 22, 1995Date of Patent: December 10, 1996Assignee: Lucent Technologies, Inc.Inventor: Lawrence Bernstein
