Patent number: 11950835Abstract: Methods and systems for distributing electrical energy to tissue which minimize Joule heating, thermal effects, and/or thermal damage, without sacrificing efficacy of treatment, are described. The methods and systems are particularly suitable to electrical energy-based therapies employing multiple electrodes, such as arrays of electrodes.Type: GrantFiled: June 29, 2020Date of Patent: April 9, 2024Assignees: Virginia Tech Intellectual Properties, Inc., AngioDynamics, Inc.Inventors: Timothy J. O'Brien, Robert E. Neal, II, Rafael V. Davalos

Patent number: 9374652Abstract: A plurality of acoustic sensors in a non-anechoic environment are calibrated with the aim of removing manufacturing tolerances and degradation over time but preserving position-dependent differences between the sensors, The sensors are excited by an acoustic stimulus which has either time-dependent characteristics or finite duration. The calibration is to be based on diffuse-field excitation only, in which indirect propagation (including single or multiple reflections) dominate over any direct-path excitation. For this purpose, the calibration process considers only a non-initial portion of sensor outputs and/or of an impulse response derived there-from. Based on these data, a frequency-dependent magnitude response function is estimated and compared with a target response function, from which a calibration function is derived.Type: GrantFiled: March 21, 2013Date of Patent: June 21, 2016Assignee: Dolby Laboratories Licensing CorporationInventors: Timothy J. Neal, Glenn N. Dickins

Patent number: 9173025Abstract: A system, a method, logic embodied in a computer-readable medium, and a computer-readable medium comprising instructions that when executed carry out a method. The method processes: (a) a plurality of input signals, e.g., signals from a plurality of spatially separated microphones; and, for echo suppression, (b) one or more reference signals, e.g., signals from or to be rendered by one or more loudspeakers and that can cause echoes. The method processes the input signals and one or more reference signals to carry out in an integrated manner simultaneous noise suppression and out-of-location signal suppression, and in some versions, echo suppression.Type: GrantFiled: August 9, 2013Date of Patent: October 27, 2015Assignee: Dolby Laboratories Licensing CorporationInventors: Glenn N. Dickins, Timothy J. Neal, Mark S. Vinton

Patent number: 9064503Abstract: One or more audio signals are processed using a multi-stage (hierarchical) voice and/or signal activity detector (VAD/SAD). A first stage is capable of reducing the workload bandwidth by employing an inexpensive VAD/SAD processor. One or more subsequent stages may further process the audio signals from the first stage. Other implementations may include a first stage that also performs continuity preservation between last blocks of audio signal and the first blocks of audio after it is detected that relevant audio signals are resumed. In yet other implementations, the first stage may extract features from audio signals when they are presented in their coded domain, and possibly with little or no decoding of the audio signal.Type: GrantFiled: March 21, 2013Date of Patent: June 23, 2015Assignee: Dolby Laboratories Licensing CorporationInventors: Glenn N. Dickins, Timothy J. Neal, Yen-Liang Shue

Patent number: 8804977Abstract: An echo suppression system and method, and a computer-readable storage medium that is configured with instructions that when executed carry out echo suppression. Each of the system and the method includes the elements of a linear echo suppressor having a reference signal path, with a nonlinearity introduced in the reference signal path to introduce energy in spectral bands. Unlike an echo canceller, the echo suppression system and method are relatively robust to errors in the introduced nonlinearity.Type: GrantFiled: March 16, 2012Date of Patent: August 12, 2014Assignee: Dolby Laboratories Licensing CorporationInventors: Timothy J. Neal, Glenn N. Dickins
