Abstract: Electrical machine arrangements have advantages with regard to providing local electrical power and starting. Embedding such electrical machine arrangements in machinery such as gas turbine engines is advantageous in removing mechanical linkages and reducing aerodynamic drag. However, the components utilized must be able to withstand harsh environmental conditions and therefore the DC link capacitor used for smoothing of voltage fluctuations are limited to relatively low capacitance densities. Low density DC link capacitors require large sizes which render electrical machines less acceptable for embedded usage. By providing offset of electrical current in inductance elements such as stator windings and stator coils of electrical machines in dead periods of the cycle a reduction in DC link capacitor requirements is achieved reducing the size, weight and complexity of installing electrical machines in gas turbine engines.

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 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 an example embodiment, a method is provided. In this method, a network address query is received.

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: Ozone laundry systems and related methods are shown and described. In one embodiment, an ozone laundry system includes a washing machine; an ozone generator, a Venturi-injector, a secondary injection device, and an ozone control system (OCS). The washing machine may have a vented drum for holding laundry and a liquid wash bath, and include a plurality of operational configurations. The OCS may be configured to provide ozone to the Venturi-injector when the washing machine is in the fill configuration, and provide ozone to the secondary injection device when the washing machine is in the wash configuration. The result is a system that is able to maintain ozone at a high level for a duration.

Abstract: Flexible valves principally (although not necessarily exclusively) for automatic swimming pool cleaners are addressed. The valves have generally parabolic closure regions and do not present linear transverse cross-sections to water flowing through them. The closure regions may extend substantially below the transverse center lines of the valves, which additionally may include teeth at or near hinges of the closure regions. Including the hinges reduces likelihood of undesired wear at or near the outlets of the valves.

Abstract: A method of controlling a machine drive having a driveline PTO establishes a driveline torque perturbation via conversion of internal inertia through two transmission neutral conditions. In an example, when a request is received, e.g., from an operator, to shift the driveline PTO from a first mode to a second mode, the transmission is automatically modulated between its first neutral condition and its second neutral condition while the driveline PTO is shifted from the first mode to the second mode, thus minimizing torque lock and facilitating mode changes.
