    • An automatic service water tap is disclosed in which a battery operated motor is provided for controlling a water supply valve in response to the presence or absence of an object positioned within the range of an infrared generating and detecting system mounted in the tap. The valve operates using only a small amount of electric power under the control of a circuit which draws no electric power once the valve is moved to its opened or closed condition. Thus the consumption of the electric power is minimized to almost zero and the valve can be utilized for a long period of time only with a small single battery.
    • 公开了一种自动服务水龙头,其中提供电池驱动的电动机以响应位于安装在水龙头中的红外发生和检测系统的范围内的物体的存在或不存在来控制供水阀。 一旦阀门移动到其打开或关闭状态,阀门在电路的控制下仅使用少量的电力,该电路不吸收电力。 因此,电力的消耗被最小化到几乎为零,并且只有在使用小的单个电池的情况下,阀才能长时间使用。

    • The present disclosure generally discloses a cross-layer link discovery capability configured to support discovery of cross-layer links of a communication network. The cross-layer link discovery capability may be configured to support discovery of cross-layer links between packet network elements and optical network elements of a communication network. The cross-layer link discovery capability may be configured to support automated and reliable discovery of cross-layer links between ports of packet network elements and ports of optical network elements of a communication network. The cross-layer link discovery capability may be configured to support discovery of cross-layer links between ports of packet network elements and ports of optical network elements based on various port matching techniques, such as port classification, port isolation based on port identification, port isolation based on port probing (e.g., active probing, passive probing based on traffic migration, passive probing based on traffic injection, or other port probing types), or the like.
