Abstract: Swimming pool cleaners are detailed with filtration components attached at the rears of their bodies. At least some of the components may be external to a body, rather than within it, so as to provide greater surface area for filtered water to exit. They also may allow users to view the quantity of debris trapped in the filter without having to dissemble the cleaner. By contrast with many existing external filter bags, moreover, the components need not protrude materially above (or below) the heights of the bodies, hence avoiding creation of hydraulic drag as the cleaners move within pools, spas, or other liquid-containing vessels.

Abstract: Automatic pool cleaners (APCs) and components thereof are detailed. The APCs may include tracks for movement, with the tracks having teethed internal surfaces. The APCs additionally may supply shift mechanisms for purposes of changing direction of their movement and incorporate bladed scrubbers and easily-opening bodies.

Abstract: In an embodiment, a pluggable connector configured to removably couple an end of an optical cable to an optoelectronic module includes a first portion and a second portion. The first portion is configured to engage a latch slot of the optoelectronic module to retain within the optoelectronic module a ferrule optically coupled to optical fibers of the optical cable. The second portion is configured to engage the ferrule to prevent removal of the ferrule from within the optoelectronic module when the first portion engages the latch slot.

The heat sink includes a heat sink bottom, first and second heat sink legs, and first and second heat sink slide locks. The first and second heat sink legs extend downward from opposite ends of the heat sink bottom. The first and second heat sink slide locks extend inward from the first and second heat sink legs. The heat sink bottom is configured to be in thermal contact with a housing top of the housing. Each of the first and second heat sink slide locks is configured to be respectively disposed beneath the first and second housing slide locks when the heat sink is removably secured to the housing.

Abstract: Present disclosure relates to methods for preparing BGP update messages for transmission and processing received update messages. The methods are based on grouping path attributes common to a plurality of IP address prefixes into respective sets identified with respective set identifiers and, instead of duplicating path attributes in each BGP update message, including a respective identifier referring to a certain set of path attributes provided in an earlier BGP update message when sending subsequent update messages. Grouping of path attributes into individual sets associated with respective identifiers provides significant advantages by enabling re-use of the results of previous processing on both the sending and receiving sides associated with transmission of BGP update messages. In addition, such an approach limits the amount of information transmitted in the control plane because duplicate sets of path attributes may only be transmitted once and merely be referred to in subsequent update messages.

Abstract: Latch mechanisms for modules are disclosed. A module includes a housing and a release slide. The housing includes a first rib located on a first side of the housing and a second rib located on a second side of the housing. The release slide is slidingly positioned on the housing. The release slide includes a release slide base, a first release slide arm extending from the release slide base, and a second release slide arm extending from the release slide base. A first flange extending from the first release slide arm is positioned at least partially over the first rib. A second flange extending from the second release slide arm is positioned at least partially over the second rib.

Abstract: Embodiments of the invention provide a facer used as protective covering for an insulation product. The facer may include a metallic foil layer, a scrim layer, and a paper layer positioned adjacent the scrim layer. The facer may also include a polypropylene material forming a polypropylene layer positioned adjacent the paper layer and heat bonded to an exposed major surface of the paper layer such that a portion of the polypropylene extends into pores of the paper layer to assist in coupling the polypropylene material to the paper layer.

Abstract: In an example embodiment, a method and system is provided to determine and advertise a route advertisement in a reactive routing environment. In response to receiving a network address query with respect to a destination address at a routing device, an aggregate value, e.g. an address prefix, is determined and advertised in reply to the network address query. Determining of the aggregate value may comprise identifying within a range of network addresses represented by the aggregate value respective addresses for which the routing device does not have reachability information. The routing device may send address queries with respect to the identified addresses, to determine reachability via the routing device of those addresses. The aggregate value may be advertised conditional upon determining that a percentage of addresses within the corresponding range that can be reached via the routing device satisfies a predefined minimal coverage value.

Abstract: A system and method for facilitating connecting a switch to a network to improve network performance. In an illustrative embodiment, the system includes a first module for determining when the switch is initially connected to a network and providing a signal in response thereto. A second module selectively forms adjacencies with peers of the switch in response to the signal and based on one or more predetermined parameters. In a more specific embodiment, the switch is a router or Layer-3 (L3) switch. The one or more predetermined parameters include a load factor, values pertaining to capabilities of a processor included in the router, bandwidth capabilities of the interface and/or the router, internal router queue counts, and so on. The router employs a routing protocol such as Enhanced Interior Gateway Routing Protocol (EIGRP). The second module throttles and adjacency-formation rate based on the predetermined parameters.

Abstract: Fluid-powered devices are detailed. The devices may be utilized as motors or pumps, for example, and are capable to switching dynamically between these functions. They additionally may use surface-area, rather than solely pressure, differentials to produce rotary motion.

Abstract: Automatic pool cleaners (APCs) and components thereof are detailed. The APCs may turn feet, rather than entire bodies, to change direction and may provide water-flow paths through the bodies that are oriented vertically. Thus, unlike existing disc-based cleaners, the APCs may reduce influence of connected hoses on their movements within pools.

Abstract: A hose joint for a pool cleaner or other apparatus that includes at least two swivels. The first swivel is configured to rotate about a first axis and the second swivel is configured to rotate about a second axis that is different from the first axis. In some embodiments, one of the swivels is configured to rotate approximately 360 degrees about its axis of rotation. In this way, the hose joint has at least two directions of freedom in at least two different planes that help the cleaner move independently from a hose attached to the hose joint.
