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: Latching mechanisms for electronic modules. In one example embodiment, a latching mechanism for an electronic module includes a latch, a latch return spring, and a release slide. The latch is configured to rotate between a latched position and an unlatched position. The latch includes a latch arm on a first end of the latch and an engagement pin on a second end of the latch. The latch return spring is configured to bias the latch in the latched position. The release slide includes a slide ramp. The slide ramp is configured to engage the latch arm as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

Abstract: Techniques for measuring Peer-To-Peer (P2P) networks are provided. P2P are initially seeded with links to feigned content. As a P2P participant accesses a link, metrics are recorded about the P2P network being used by the participant. The metrics are used to form measurements to compare different P2P networks relative to one another.

Abstract: Detailed are components of cleaners of fluid-containing vessels such as pools and spas.

The coating is a water-resistant material which may be an elastomer, such as a polyurea, polyurethane, or polyurethane/polyurea hybrid. A method for encapsulating a bulkhead member is also provided. The method includes the steps of providing a bulkhead member, spraying the bulkhead member with the components of an elastomer to coat or encapsulate the bulkhead, and allowing the components to cure for a period of time sufficient to form the water-resistant elastomer.

Abstract: A social networking system obtains parental authorization from a parent for a child to access a computing resource, where the parent and the child are users of the social networking system. The child user may request the authorization by identifying a purported parent user. The social networking system attempts to verify the validity of the purported parent user's account, the age of the user associated with the purported parent's account, and/or the existence of a parent-child relationship between users of the accounts associated with the purported parent and the child. The social networking system makes these determinations, at least in part, using social and transactional information associated with the purported parent user's account and the child user's account in the social networking system. Upon verification of these items, the social networking system may allow the purported parent to provide authorization responsive to the child's request to access the computing resource.

Abstract: In one embodiment, a system includes a memory and a processor communicatively coupled to the memory. The processor is operable to receive a first notification and determine whether the first device is associated with the user account. The processor is also operable to communicate a token to the first device in response to determining that the first device is associated with the user account. Additionally, the processor is operable to receive a second notification comprising a request to authenticate the user. The processor may also determine if the second notification comprises the token. The processor is operable to authenticate the user if the second notification comprises the token. The processor is also operable to authenticate the user if the second device is not associated with the user account and the second notification comprises user credentials associated with the user account.

Abstract: A system includes a processor and memory operable to store user account information. The processor receives a transaction message transmitted by a transaction device in a transaction environment, the transaction message comprising transaction data obtained by the transaction device from a transaction code presented by a mobile computing device of a user. The processor further accesses the user account information and determines, using the user account information and the transaction data from the transaction message, whether the user is authenticated. The processor transmits an authentication message indicating whether the user is authenticated to the transaction device.

Abstract: Devices for cleaning vessels, especially swimming pools, are discussed. The devices may include repositionable in-line valves, with the valves typically moving laterally (from side to side) and changing the initial direction of the main fluid-flow path through the valves and corresponding cleaner bodies. Asymmetric feet may be utilized as part of the devices, whose bottom bearing surfaces may include elongated strips of material placed parallel to the normally-forward direction of travel of the devices. Discs of non-uniform flexibility also may be employed, and blocking tabs or gripping material may be used to inhibit undesired backward movement of a cleaner when its operation commences.

Abstract: Detailed are components of cleaners of fluid-containing vessels such as pools and spas. The components may incorporate combined discs and footpads and attach to other components of a cleaner other than by receipt of a boundary of a central aperture into a groove. The components nevertheless may continue to include central apertures as appropriate.

Abstract: Provided herein is a novel approach to simultaneous fiber presence detection and improved laser eye safety of an optical transceiver. The subject optical transceiver is fitted with at least one switch in its receptacle that controls the laser diode and indicates the presence of a fiber (or fibers) within such a receptacle. If a fiber is present within the subject module receptacle, the laser switch is permitted to be “on”, whereas the absence of a fiber will prevent the laser switch from turning on, thereby permitting effective control of the laser at a single point of failure within the entire optical transceiver system. The typical optical transceivers of today exhibit limited optical power output due to eye safety limit criteria.

Abstract: A system includes a memory for storing user account information and mobile device information; and a processor. The processor receives a request for a transaction. The request includes a user identifier, a transaction amount, and a transaction recipient identifier. The processor further generates a transaction code. The processor further communicates the transaction code to a user device. The processor further receives, from a mobile device, a transaction confirmation message, wherein the user device and the mobile device are separate devices. The transaction confirmation message includes a confirmation of the request for the transaction and a unique identifier of the mobile device. The processor further compares the unique identifier of the mobile device with the stored mobile device information. In response to a determination that the unique identifier of the mobile device matches the stored mobile device information, the processor further allows the transaction to occur.

Downwardly-extending wear surfaces may be present as well within the pockets.

Abstract: An internet browsing gateway is utilized to locate mobile web content and improve search capabilities for wireless devices. Mobile browsing data is logged as web pages are requested from and returned to wireless devices associated with the same wireless network. An index server continually updates search indexes in real time as users request searches and search results are returned. As a result, the mobile content that is discovered becomes more relevant for users of the same wireless network or mobile carrier. In other words, the search results are more localized in accordance with the location of the wireless network that services the mobile users within a specific geographic region. When a web search is requested from a wireless device, the index server queries the search indexes. The search results are ranked using a search algorithm that incorporates the browsing data to improve the accuracy and relevance of searches.
