Patent number: 8811603Abstract: An echo canceler circuit (10) and method attenuates at least post-echo canceler uplink data (90) to produce attenuated uplink data (100) in response to uplink echo return loss based attenuation data (40). The echo canceler circuit (10) includes an echo return loss based attenuation data generator (20) and at least an uplink data attenuator (30). The echo return loss based attenuation data generator (20) produces the uplink echo return loss based attenuation data (40) in response to echo return loss data (70). The echo return loss data (70) is based on at least one of: attenuated downlink data (50), pre-echo canceler uplink data (60), and/or amplifier gain data (80). The uplink data attenuator (30) attenuates the post-echo canceler uplink data (90) to produce attenuated uplink data (100) based on the uplink echo return loss based attenuation data (40).Type: GrantFiled: July 17, 2012Date of Patent: August 19, 2014Assignee: Continental Automotive Systems, Inc.Inventors: James B. Piket, Keith L. Owens, Christopher W. Springfield

Patent number: 7046794Abstract: A double talk activity detector (30) and method for an echo canceler circuit (10) improves the probability of detecting a double talk condition based on at least pre-echo canceler uplink data (40). The echo canceler circuit (10) includes a double talk activity probability data generator (30) and an echo canceler stage (20). The double talk activity probability data generator (30) receives pre-echo canceler uplink data (40) and in response produces double talk activity probability data (50). The echo canceler stage (20) is coupled to the double talk activity probability data generator (30) and receives downlink data (60), pre-echo canceler uplink data (40) and the double talk activity probability data (50) and in response produces attenuated uplink data (70).Type: GrantFiled: December 12, 2003Date of Patent: May 16, 2006Assignee: Motorola, Inc.Inventors: James B. Piket, Keith L. Owens, Christopher W. Springfield

Patent number: 6166621Abstract: A communication device such as pager (100) includes a controller (110) which helps decode an incoming message having important information and stores it in memory (112). A user control (116) such as a "Read" control switch is then used to display the message on the display (106). In accordance with one aspect of the present invention, controller (110) locates the important information found in the stored message and causes it to be displayed on one or more stationary display lines (416) which do not change even when the user scrolls through different display screens (408-412) to read the entire message. In an alternate embodiment of the invention, the pager controller (110) will have stored a set of rules which will help it locate the important information (e.g., telephone number, etc.) found in a stored message. Once the important information is found, the controller (110) will cause this information to be displayed as a stationary display line when displaying the message in one or more display screens.Type: GrantFiled: January 29, 1998Date of Patent: December 26, 2000Assignee: Motorola, Inc.Inventors: John M. Burgan, Kenneth S. Lerner, Keith L. Owens
