    • A hand-operated cleaning system includes an ON/OFF control unit snap-on mountable onto a pressurized container having a valve stem for delivering cleaning liquid. This control unit includes an outer cap with resilient fingers adapted to snap-grip engage and mount the control unit onto a top rim of the container. An inner cap is mounted within the outer cap for ON/OFF helical turning movement so that turning the inner cap in the ON direction depresses the valve stem for releasing pressurized liquid from its container, and turning it in the OFF direction stops such release. A fluid passageway extends from the valve stem through the inner cap to a length of flexible tubing coupled to the inner cap and extending to a remotely-located, hand-held applicator wand. This applicator wand has a fluid passageway communicating with the flexible tubing for providing a path through the wand to its nozzle end. A valve is positioned in the wand for operation by a button actuator. Depressing this button actuator by a user's thumb or forefinger opens the valve for delivering fluid out through an axial bore of the nozzle. A brush is mountable in the nozzle bore so that solvent dispensed through the nozzle bore for brushing application of dispensed liquid onto a surface to be cleaned. The button-actuated valve is spaced away from the end of the elongated nozzle for enabling the nozzle and brush to reach into places of difficult access.
    • 手动清洁系统包括可安装到具有用于输送清洁液体的阀杆的加压容器上的ON / OFF控制单元。 该控制单元包括具有弹性指状件的外盖,该外盖适于卡扣卡合并将控制单元安装到容器的顶部边缘上。 内盖安装在外盖内,用于ON / OFF螺旋转动,使得在ON方向转动内盖压下阀杆,用于从其容器释放加压液体,并且在OFF方向转动停止这种释放。 流体通道从阀杆通过内盖延伸到连接到内盖并延伸到位于远处的手持式施加器棒的柔性管的一段长度。 该施加器棒具有与柔性管连通的流体通道,用于提供穿过该杆至其喷嘴端的路径。 阀门定位在魔杖中,用于由按钮致动器操作。 用户的拇指或食指按下该按钮致动器打开阀门,用于通过喷嘴的轴向孔输送流体。 刷子安装在喷嘴孔中,使得溶剂通过喷嘴孔分配,用于刷涂分配的液体到待清洁的表面上。 按钮致动阀与细长喷嘴的端部间隔开,以使喷嘴和刷子能够到达难以进入的位置。

    • Systems and methods for consumer price index determination using panel-based and point-of-sale market research data are disclosed. Disclosed example methods to determine a consumer price index include defining a plurality of item strata for use in determining the consumer price index, each item stratum being defined by specifying a plurality of attributes associating items with the item stratum, obtaining pricing information for a plurality of items, at least some of the plurality of items having not been preselected for inclusion in any of the plurality of item strata, determining price differentials for the plurality of item strata, a respective price differential for a respective item stratum being determined by combining the pricing information for a group of items, from the plurality of items, having the specified attributes defining the respective item stratum, and combining the determined price differentials for the plurality of item strata to determine the consumer price index.

    • A system and method for determining an operational status of a segment of a hybrid fiber coax (HFC) cable network. Subscriber premises units (SPUs) connected to the HFC cable network are “pinged” and their responses recorded. The two most responsive SPUs in each node of the HFC cable network are identified. The most responsive SPU is added to a primary ping list and the next most responsive SPU is added to a secondary ping list. The SPUs on the primary list are “pinged” and their responses recorded. If an SPU on the primary list fails to respond, the secondary SPU associated with the node is pinged. If both the primary and secondary SPU associated with a node fail to respond to the “ping,” the node is identified as non-responsive. If all of the nodes associated with a modulator (or a demodulator) are identified as non-responsive, the modulator (or demodulator) is identified as “non-responsive.” Additionally, network devices are pinged and their responses noted. Using the responsiveness of nodes and network devices, faults in segments in an HFC cable network can be identified and located.
    • 一种用于确定混合光纤同轴电缆(HFC)电缆网络的段的操作状态的系统和方法。 连接到HFC电缆网络的用户位置单元(SPU)被“ping”并记录其响应。 识别HFC电缆网络每个节点中最响应的两个SPU。 最响应的SPU被添加到主ping列表中,并且下一个最响应的SPU被添加到辅助ping列表。 主要列表上的SPU被“ping”并记录其响应。 如果主列表中的SPU无法响应,则与该节点关联的辅助SPU被ping通。 如果与节点相关联的主SPU和辅助SPU都无法响应“ping”,则节点被识别为无响应。 如果与调制器(或解调器)相关联的所有节点被识别为非响应,则调制器(或解调器)被标识为“无响应”。另外,网络设备被ping通并且其响应被注明。 使用节点和网络设备的响应能力,可以识别和定位HFC网络中段的故障。
