Patent number: 11575556Abstract: A communication system is configured to generate a perturbed signal by perturbing an amplitude of a spectrum of an original signal in one or more spectral regions, and to propagate the perturbed signal through components of the communication system. The communication system is further configured to obtain a measurement of the perturbed signal in a first spectral region of the one or more spectral regions following the propagation of the perturbed signal, and to calculate an estimate of an impairment associated with the communication system based on the measurement.Type: GrantFiled: August 27, 2021Date of Patent: February 7, 2023Assignee: Ciena CorporationInventors: Francisco Javier Vaquero-Caballero, Michael Andrew Reimer, Seb Savory, Maurice O'Sullivan, Mohammad Ebrahim Mousa Pasandi, David Ives, Michael Hubbard, Andrew D.

Patent number: 9670852Abstract: A method for operating a turbocharged engine is disclosed. In one example, during a first condition an engine operation is adjusted in response to a turbocharger expansion ratio exceeding a first limit and during a second condition an engine operation is adjusted in response to the turbocharger expansion ratio exceeding a second limit that differs from the first limit. Degradation of the engine may be reduced under some engine operating conditions by adjusting engine operation in response to the turbocharger expansion ratio.Type: GrantFiled: January 13, 2015Date of Patent: June 6, 2017Assignee: Ford Global Technologies, LLCInventors: Brien Lloyd Fulton, Gopal Krishna Chamarthi, Dean Pennala, David Ives, David Robert Nader, Paul Martin Niessen, Jason Ronald Smith

Patent number: 6813530Abstract: An audio mixing console having a panning circuit in which panning is controlled by an automated motorized panning joystick. According to the invention, the panning moves can be more easily made with the joystick; stored and played back by using automation and more easily changed and viewed by using a motor to position the joystick. A joystick system panel includes switches and displays to vary the operational mode of the panning system. A touch sensitive joystick provides for instantaneous control of the control functions of the console.Type: GrantFiled: July 23, 2001Date of Patent: November 2, 2004Assignee: GLW, Inc.Inventors: David Ives, Sam Demonbreun
