Patent number: 8068437Abstract: Empirically derived models are used to relate user perception to objectively measurable characteristics, under a criterion of nearly perfect co-variance between predicted MOS values and the variations in the values of the objectively measurable characteristics. In the example context of evaluating packet switched telephony service, the present invention eliminates the need to perform subjective tests to characterize each combination of codec type and transmission protocol.Type: GrantFiled: April 11, 2005Date of Patent: November 29, 2011Assignee: Verizon Business Global LLCInventor: William C.

Patent number: 6985559Abstract: A device is disclosed that uses an continuous analytical function representing mapping data relating object voice connection measurements to likely user perception of the quality of a voice connection. The device is compact and inexpensive. It can be implemented on a single integrated circuit, or on a single printed circuit board. CPU processing time is significantly reduced. The device obtains a real-time estimate of likely user perception of a given connection in terms of a user perception rating system. The device is reprogrammable, enabling it to be updated as more accurate mapping data is obtained.Type: GrantFiled: February 8, 2001Date of Patent: January 10, 2006Assignee: MCI, Inc.Inventor: William C.

Patent number: 6580782Abstract: A system and method for testing a telephone connection using an interactive telephone response module (ITRM). In one embodiment, the ITRM is connected between the handset and station set of a telephone terminating one end of the connection to be tested. In another embodiment, the ITRM is connected between the telephone connection and the station set of a telephone terminating one end of the connection to be tested. By operating switches on the ITRM, a user can impose predetermined conditions on the connection. A test coordinator located at a test point or other termination in the telephone network then tests the connection under the predetermined conditions.Type: GrantFiled: October 6, 1999Date of Patent: June 17, 2003Assignee: MCI Communications CorporationInventors: William C.

Patent number: 6564181Abstract: A system that provides measurements of speech distortion that correspond closely to user perceptions of speech distortion is disclosed. The system calculates and analyzes first and second discrete derivatives to detect and determine the incidence of change in the voice waveform that would not have been made by human articulation because natural voice signals change at a limited rate. Statistical analysis is performed of both the first and second discrete derivatives to detect speech distortion by looking at the distribution of the signals. For example. the kurtosis of the signals is analyzed as well as the number of times these values exceed a predetermined threshold, Additionally. the number of times the first derivative data is less than a predetermined low value is analyzed to provide a level of speech distortion and clipping of the signal due to lost data packets.Type: GrantFiled: April 24, 2001Date of Patent: May 13, 2003Assignee: WorldCom, Inc.Inventor: William C. Hardy

Patent number: 6553061Abstract: A device for detecting a predetermined waveform in a received signal and synchronizing the detected waveform to the predetermined waveform is disclosed. The device includes a memory element for storing a reference set of encoded values. The reference set representing an encoded version of the predetermined waveform. An encoder is used to PCM encode the signal to obtain sets of encoded values representing the received signal. A processor calculates the statistical correlation coefficient of the reference set and the signal sets. The processor then determines the maximum statistical correlation coefficient. The predetermined waveform is detected in the signal if the maximum statistical correlation coefficient is greater than or equal to a predetermined threshold value. The device provides a compact, inexpensive, and fast method for detecting a known reference waveform in a received signal.Type: GrantFiled: February 8, 2001Date of Patent: April 22, 2003Assignee: WorldCom, Inc.Inventor: William C. Hardy

Patent number: 6466673Abstract: An apparatus for suppressing an induced intracranial noise or vibrational signal within a patient's head due to a drilling or cutting medical instrument. The apparatus includes a mechanism for sensing the intracranial vibrational signal induced within the patient's head. The apparatus also includes a mechanism for adaptively generating an intracranial vibrational suppression signal from the intracranial vibrational signal as a function of time. In addition, the apparatus provides a mechanism for applying the intracranial vibrational suppression signal to the patient's head for suppressing the induced intracranial noise or vibrational signal.Type: GrantFiled: May 11, 1998Date of Patent: October 15, 2002Assignee: MCI Communications CorporationInventor: William C.

Patent number: 5448624Abstract: The present invention automatically initiates a telephone call to a given destination. At the same time, the progress of the call is monitored. The time of a ring back and voice answer received from the destination are recorded to an output file. At the end of the voice answer, a pre-recorded voice message is sent by the system to the person answering at the destination. Thereafter, the recorded data is used to determine the response time for that particular telephone destination. A plurality of destinations can be tested.
