摘要： An overhead microphone assembly (8110; 8120) using multiple unidirectional microphone elements (8112, 8114, 8116; 8111, 8113, 8115). The microphone assembly (8110; 8120) is installed overhead, generally above all the desired sound sources and below the undesired sound sources. The signals from these multiple microphone elements (8112, 8114, 8116; 8111, 8113, 8115) are fed into a microphone steering processor which can mix and gate the signals to ensure the best signal/noise ratio. The steering processor may also track the sound source dynamically when such tracking (source locating) is desired. The resulting audio signal from the steering processor may be further processed, such as echo canceling, noise reduction and automatic gain control.

摘要翻译： 使用多个单向麦克风元件（8112,8114,8116; 8111,8113,8115）的顶置式麦克风组件（8110; 8120）。 麦克风组件（8110; 8120）安装在顶部，通常高于所需的声源并且低于不需要的声源。 来自这些多个麦克风元件（8112,8114,8116; 8111,8113,8115）的信号被馈送到麦克风转向处理器中，麦克风转向处理器可以混合和对门限进行信号以确保最佳信号/噪声比。 当需要这种跟踪（源定位）时，转向处理器还可以动态地跟踪声源。 可以进一步处理来自转向处理器的结果音频信号，例如回波消除，降噪和自动增益控制。

摘要： Methods and devices for controlling room function devices from a single conference unit. A conference unit can be a video conference unit (301) or a speakerphone (350). Controlled devices may include external loudspeakers, microphones, room function controllers, powered doors, powered windows, powered window shades or blinders, video screens etc. The connections between devices may be wired, wireless, or a combination of both.
