    • Embodiments of the present invention disclose an image-based video conference control method, terminal, and system. The method includes the following steps: sending a control request message to a network-side device (101); dynamically displaying image information according to a control message fed back by the network-side device (102); and editing an image according to the image information to complete video conference control (103). Through the embodiments of the present invention, an image of a single or multiple conference site pictures can be directly selected for operation according to abundant information provided by each conference site picture in combination with an operation of a remote controller, so that all kinds of conference control operations in a video conference are implemented, and a need of entering a multi-level menu to carry out complicated video conference control is avoided.
    • 本发明的实施例公开了一种基于图像的视频会议控制方法,终端和系统。 该方法包括以下步骤:向网络侧设备(101)发送控制请求消息; 根据由所述网络侧设备(102)反馈的控制消息来动态地显示图像信息; 以及根据图像信息编辑图像以完成视频会议控制(103)。 通过本发明的实施例,可以根据每个会场图片提供的丰富的信息,结合遥控器的操作,直接选择单个或多个会场图片的图像进行操作,从而使各种会议 实现视频会议中的控制操作,并且避免了进入多级菜单以执行复杂的视频会议控制的需要。

    • An apparatus is provided, which includes a dust detector, a voltage source, and a controller. The dust detector includes two opposing surfaces and a conductive dust sensor. The two opposing surfaces are disposed in spaced, opposing relation to allow for the passage of airflow between the surfaces, and the conductive dust sensor is disposed at a surface of the two opposing surfaces. The voltage source is configured and controlled to establish an electrostatic field at least partially between the two opposing surfaces to facilitate directing conductive particles in the airflow passing between the two opposing surfaces towards the dust sensor. The controller monitors for a leakage current within the conductive dust sensor and determines whether the leakage current exceeds a predetermined trigger level indicative of the presence of conductive dust, and if so, automatically indicates a conductive dust warning.
    • 提供了一种装置,其包括灰尘检测器,电压源和控制器。 尘埃检测器包括两个相对的表面和一个导电粉尘传感器。 两个相对的表面以间隔开的相对关系设置成允许气流在表面之间通过,并且导电粉尘传感器设置在两个相对表面的表面。 电压源被配置和控制以在至少部分地在两个相对的表面之间建立静电场,以有助于将通过两个相对表面之间的空气中的导电颗粒导向尘埃传感器。 控制器监控导电粉尘传感器内的漏电流,并确定泄漏电流是否超过表示存在导电粉尘的预定触发电平,如果是,则自动指示导电粉尘警告。
