    • A cover assembly is provided for preventing water infiltration into an in-floor receptacle fitting, such as a poke-thru fitting. The fitting includes an internal compartment which is accessible through an opening in the surface of the floor. The cover assembly includes a trim flange which overlies the floor opening. The trim flange supports at least one receptacle, such as a power receptacle, within the fitting such that the receptacle can be interconnected within the inner compartment with source cables that enter the fitting from below the floor, and can be interconnected from above with a connector such as a male electrical plug. A cover plate is mounted on the trim flange and overlies the receptacles carried by the fitting. The cover plate includes a plurality of access doors. Each of the access doors is movable between a first position at which it overlies an associated receptacle to prevent access thereto and a second position at which the associated receptacle is exposed and accessible from above. A first seal member interposed between the cover assembly first and second portions and adapted to seal against water infiltration therebetween. The first seal is in the form of a planar gasket which is sandwiched between the cover assembly first and second portions. The first seal overlies the receptacles and at least the portions of the trim flange which surround the perimeters of the receptacles. Access openings in the first seal provide access to the receptacles. Ribs extend upwardly around the perimeters of the openings and form an abut against the bottoms of the access doors when the doors are at their closed positions. The interference fit between the ribs and the access doors seals against water infiltration therebetween and into the fitting. The first seal further includes a downwardly extending rib which engages in a reciprocal groove formed in the trim flange around the perimeter of the receptacles. A second seal, in the form of at least one compressible gasket, extends around the perimeter of the floor opening and is adapted to be compressed between the cover assembly first portion and the floor's surface when the first portion is connected to the fitting.

    • A non-metallic floor box for use in electrical in-floor power and communication distribution systems includes a plurality of sets of vertically aligned indexing teeth formed in the interior of the housing side wall. An adapter ring is sized for insertion into the housing interior for supporting an activation kit above the housing interior compartment. The adapter ring has flanges extending from its periphery which are positioned to reciprocally mate with the vertical rows of teeth when the adapter ring is inserted into the housing interior compartment. The flanges and teeth are constructed to permit the ring to be inserted into the housing but to restrict its removal from the housing after its insertion therein. An activation cover is securable to the top of the adapter ring and extends beyond the perimeter of the side wall to limit the distance the adapter ring can be inserted into the housing. The floor box accommodates dual services through the use of two sets of parallel aligned conduit hubs and a divider which is insertable into the housing interior between the two sets of conduit hubs. The closed top of the housing acts as a concrete cover during the pouring of the floor, and as a temporary debris cover after it is cut off but prior to activation of the floor box. Gradient markings on the interior of the floor box provide a quick and accurate measurement of interior floor box volume for inspection and building code compliance.
    • 用于电气地板内电力和通信分配系统的非金属地板箱包括形成在壳体侧壁内部的多组垂直对齐的分度齿。 适配器环的尺寸适于插入壳体内部,用于支撑在壳体内部隔间上方的启动套件。 适配器环具有从其周边延伸的凸缘,当凸缘插入到壳体内部隔室中时,凸缘定位成与垂直排的齿轮往复配合。 凸缘和齿被构造成允许环插入壳体中,但是在其插入其中之后限制其从壳体的移除。 活动盖可固定到适配器环的顶部并且延伸超过侧壁的周边以限制适配器环可以插入到壳体中的距离。 地板箱通过使用两组平行排列的导管轮毂和一个可插入到两组导管轮毂之间的壳体内部的分隔器来容纳双重服务。 在地板浇注期间,外壳的封闭顶部充当混凝土盖,并且在切割之后但在启动地板箱之前作为临时碎片盖。 地板箱内部的梯度标记可以快速准确地测量室内地板箱体积,以进行检查和建筑规范的合规。

    • A method and apparatus for synchronizing streaming media with multiple output devices. One or more media servers serve media streams to one or more output devices (i.e., players). For playback synchronization, one output device is the “master”, whereas the remaining output devices are “slaves”. More data is requested from the media server by the “master” device to maintain a nominal buffer fill level over time. The “slave” devices receive streamed data from the media server at the rate determined by the master device's data requests, and the average rate of data flow over the streaming network is thus controlled by the frequency of the single “master” device's crystal. “Slave” devices make playback rate corrections to maintain respective buffer fill levels within upper and lower threshold levels. For slow networks, each media data packet timestamp is calculated from the time the master's buffer reaches nominal level.
    • 一种用于使流媒体与多个输出设备同步的方法和装置。 一个或多个媒体服务器向一个或多个输出设备(即播放器)提供媒体流。 对于播放同步,一个输出设备是“主站”,而其余的输出设备是“从站”。 通过“主”设备从媒体服务器请求更多数据,以保持一段时间内的标称缓冲区填充级别。 “从设备”设备以由主设备的数据请求确定的速率从媒体服务器接收流数据,并且因此通过单个“主”设备的晶体的频率来控制流媒体网络上的平均数据流速度。 “从设备”使播放速率更正,以在上限和下限阈值范围内维持相应的缓冲区填充水平。 对于慢速网络,每个媒体数据包时间戳是从主缓冲区达到标称电平的时间开始计算的。
