    • Embodiments of the present invention include a camera having two modes: a visible light imaging mode (day-mode) and an IR imaging mode (night-mode). In the visible light imaging mode, an IR filter is in line with the lens assembly. In the IR imaging mode, the IR filter is mechanically removed, and IR light is allowed to pass to the sensor. In one embodiment, in the IR imaging mode, IR lighting is provided by an IR LEDs on the camera to illuminate the scene. In one embodiment, the various components are chosen, balanced and optimized so that images captured using visible light and images captured using non-visible light are both in focus. In one embodiment, an algorithm determines when there sufficient visible light is present and when it is not, and thus determines when to switch the camera from one mode to another.
    • 本发明的实施例包括具有两种模式的相机:可见光成像模式(日模式)和IR成像模式(夜模式)。 在可见光成像模式下,IR滤光片与透镜组件一致。 在红外成像模式下,IR滤光片被机械去除,并允许红外光通过传感器。 在一个实施例中,在IR成像模式中,IR照明由相机上的IR LED提供以照亮场景。 在一个实施例中,选择,平衡和优化各种组件,使得使用可见光捕获的图像和使用不可见光捕获的图像都是焦点。 在一个实施例中,一种算法确定何时存在足够的可见光,何时不存在,并且因此确定何时将相机从一种模式切换到另一种模式。

    • Processes for biofilm or microorganism growth control in an aqueous system such as a pulp, paper or board manufacturing system are described in which a halogenated hydantoin is added to the aqueous system in combination with haloamine, chlorine dioxide or a combination thereof. The halogenated hydantoin is preferably a fully or partially halogenated dialkyl hydantoin, and more preferably 5,5-dimethyl hydantoin or 5-methyl-5-ethyl hydantoin. The haloamine is preferably a monohaloamine, dihaloamine, trihaloamine, or a combination thereof, and more preferably monochloramine, monobromamine, bromochloroamine or a combination thereof. The halogenated hydantoin is preferably added to the aqueous system in portions of the system susceptible to gas phase corrosion, such as the short loop of the system, and the haloamine and chlorine dioxide are preferably added to other portions of the system. The halogenated hydantoin and haloamine and/or chlorine dioxide maintain good compatibility with each other in the absence of excess free chlorine.
    • 描述了在水系统如纸浆,纸或板制造系统中的生物膜或微生物生长控制的方法,其中将卤代乙内酰脲与卤胺,二氧化氯或其组合组合加入到水系统中。 卤化乙内酰脲优选为完全或部分卤化的二烷基乙内酰脲,更优选为5,5-二甲基乙内酰脲或5-甲基-5-乙基乙内酰脲。 卤代胺优选为单卤代胺,二卤代胺,三卤代胺或其组合,更优选一氯胺,一溴胺,溴氯胺或其组合。 卤化乙内酰脲优选在易于气相腐蚀的系统的部分系统中加入到水系统中,例如系统的短路,并且卤胺和二氧化氯优选加入系统的其它部分。 卤代乙内酰脲和卤代胺和/或二氧化氯在不存在过量游离氯的情况下保持彼此良好的相容性。
