Patent number: 8774399Abstract: A telecommunication system including a speakerphone provides a coupled signal path, including a microphone, configured to sense an incoming audio signal and an echo signal and generate a coupled signal. The echo signal includes non-linear distortion generated by a speaker of the speakerphone. An echo signal path, including an amplifier, is configured to sense the echo signal and generate an echo reference signal. The echo reference signal includes the non-linear distortion. An acoustic echo canceller is configured to receive the coupled signal from the coupled signal path, to receive the echo reference signal from the echo signal path, and to cancel out the non-linear distortion included in the coupled signal based on the non-linear distortion included in the echo reference signal.Type: GrantFiled: December 27, 2011Date of Patent: July 8, 2014Assignee: Broadcom CorporationInventors: Prakash C. Khanduri, Bosen Zhao

Patent number: 7204129Abstract: An ultrasound system determines the presence of a foreign object in a container of fluid by measuring echo signals from the outer surface of the container and the inner surface of the container. The amplitude of the echo signals are compared to determine the presence of an object in the container. The system also determines viscosity of the contained fluid by measuring a through-transmission time through the container and the fluid, measuring an outer echo transmission time of an outer echo signal from the outer surface of the container and an inner echo transmission time of an inner echo signal from the inner surface of the container, and determining a time difference between the outer echo transmission time and the inner surface transmission time.Type: GrantFiled: February 7, 2006Date of Patent: April 17, 2007Assignee: l M International CorporationInventors: Otman Adam Basir, Bosen Zhao, Gauri Mittal

Patent number: 7183930Abstract: The disclosed invention uses two sensors to capture the heartbeat and environmental noises of an occupant of a vehicle or hospital bed. One of the sensors is placed on a seat or bed frame adjacent the occupant. A second sensor is placed remotely from the occupant, on a vehicle floor, or remote portion of the bed frame. A signal conditioning module is attached to the first and second sensors for detecting the heartbeat signal. Specialized software is used for processing the signal and decision making based upon the extracted heartbeat signal. The invention is capable of operating despite environmental noise and vibrations.Type: GrantFiled: July 19, 2004Date of Patent: February 27, 2007Assignee: Intelligent Mechatronic Systems Inc.Inventors: Otman Adam Basir, Bosen Zhao

The amplitude of the echo signals are compared to determine the presence of an object in the container. The system also determines viscosity of the contained fluid by measuring a through-transmission time through the container and the fluid, measuring an outer echo transmission time of an outer echo signal from the outer surface of the container and an inner echo transmission time of an inner echo signal from the inner surface of the container, and determining a time difference between the outer echo transmission time and the inner surface transmission time.Type: ApplicationFiled: February 7, 2006Publication date: June 15, 2006Inventors: Otman Basir, Bosen Zhao, Gauri Mittal
