Abstract: The present invention relates to a method and apparatus for improving interference suppression processing and control in hearing aids communicating with a mobile station over a short-range wireless network. The hearing aid includes an acoustic echo canceller to suppress acoustic echo from the input audio signals. The mobile station also includes an echo canceller, and may include one or more switching circuits to bypass the echo canceller when the mobile station communicates with the hearing aid via the short-range wireless network. Typically, when the short-range wireless network between the hearing aid and the mobile station is established, the hearing aid and the mobile station negotiate one or more short-range wireless network profiles to determine the properties of the echo cancellers.

Abstract: A method and apparatus are disclosed for providing communication between and among multiple keyboards and a common host. The keyboards can be peers, transmitting to the host either independently (without provision for controlling interference) or cooperatively (communicating with each other prior to communicating with the common host). Alternatively, the keyboards can be prioritized, with lower-priority keyboards transmit to the host only when higher-priority keyboards are not, thereby avoiding interference with the higher-priority keyboards. Also, the keyboards can be prioritized with lower-priority keyboards communicating with the host only through the higher-priority keyboards, the higher-priority keyboards storing and forwarding data from the lower priority keyboards to higher-priority keyboards and/or the host. A method for organizing data from multiple keyboards for transmission to the host is also disclosed, in which the intended message is received by the host in the presence of interference.
