  • Patent number: 8325726
    Abstract: A network device receives a packet with a multicast nexthop identifier, and creates a mask that includes addresses of egress packet forwarding engines, of the network device, to which to provide the packet. The network device divides the mask into two portions, generates two copies of the packet, provides a first portion of the mask in a first copy of the packet, and provides a second portion of the mask in a second copy of the packet. The network device also forwards the first copy of the packet to an address of a first egress packet forwarding engine provided in the first portion of the mask, and forwards the second copy of the packet to an address of a second egress packet forwarding engine provided in the second portion of the mask.

  • Publication number: 20120300674
    Abstract: A network device provides a selector list that includes indices of child nexthops associated with the network device, where each of the child nexthops is associated with a corresponding child link provided in an aggregated bundle of child links. The network device also receives an indication of a failure of a child link in the aggregated bundle of child links, and removes, from the selector list, an index of a child nexthop associated with the failed child link. The network device further receives probabilities associated with the child links of the aggregated bundle of child links. Each of the probabilities indicates a probability of a packet exiting the network device on a child link. The network device also creates a distribution table based on the probabilities associated with the child links, and rearranges values provided in the distribution table.

  • Publication number: 20120286682
    Abstract: A bi-level lamp ballast to selectively operate two lamps is provided. The ballast includes a control circuit having an input, connected to a switching network, and an output, which provides a particular control signal based on the state of the switching network. The ballast also includes respective lamp control switches, each having respective outputs. The first switch is connected to the output and a ballast power supply. In its first state, it connects the ballast power supply to its first output, and in its second state, it connects the ballast power supply to its second output. The second switch is connected to the output and a ground. In its first state, it connects the ground to its first output, and in its second state, it connects the ground to its second output. The state of each lamp control switch depends on the control signal generated by the control circuit.

  • Publication number: 20120274229
    Abstract: A multi-strike ballast to ignite an electrodless lamp is disclosed, and includes an inverter circuit, an output voltage detection circuit (OVDC), and an inverter shutdown circuit. The inverter circuit, upon activation, sends an ignition pulse to the electrodeless lamp. The inverter circuit shut downs upon receiving a deactivation signal, and activates upon receiving an activation signal, triggering another ignition pulse. The OVDC detects an output voltage across the lamp. The inverter shutdown circuit includes a multi-strike diac and receives the detected output voltage. The multi-strike diac breaks upon the output voltage reaching a predetermined level. In response, a deactivation signal is sent to the inverter circuit. The multi-strike diac turns off upon the output voltage falling below the predetermined level. In response, an activation signal is sent to the inverter circuit, triggering a further ignition pulse. The process repeats, providing multiple ignition pulses to the lamp.

  • Publication number: 20120251718
    Abstract: Embodiments of the invention generally relate to methods and compositions for forming conformal coatings on textured substrates. More specifically, embodiments of the invention generally relate to sol-gel processes and sol-gel compositions for forming low refractive index conformal coatings on textured transparent substrates. In one embodiment a method of forming a conformal coating on a textured glass substrate is provided. The method comprises coating the textured glass substrate with a sol-gel composition comprising a solidifier. It is believed that use of the solidifier expedites the sol-gel transition point of the sol-gel composition leading to more conformal deposition of coatings on textured substrates.

  • Publication number: 20120237676
    Abstract: Embodiments of the invention relate generally to methods and compositions for forming porous low refractive index coatings on substrates. In one embodiment, a method of forming a porous coating on a substrate is provided. The method comprises coating a substrate with a sol-gel composition comprising at least one self assembling molecular porogen and annealing the coated substrate to remove the at least one self assembling molecular porogen to form the porous coating. Use of the self assembling molecular porogens leads to the formation of stable pores with larger volume and an increased reduction in the refractive index of the coating. Further, the size and interconnectivity of the pores may be controlled via selection of the self assembling molecular porogens structure, the total porogen fraction, polarity of the molecule and solvent, and other physiochemical properties of the gel phase.

  • Publication number: 20120213218
    Abstract: In an embodiment, a method comprises receiving a path advertisement comprising information about an available path and a well-known community value associated with the available path. A modified best path calculation is performed in response to receiving the available path either from a higher-ranked device or from a device that is not participating in diverse path calculation, resulting in creating a particular best path. The particular best path is advertised to other routers with or without a restriction indicator based on whether it is a client learned path or non-client iBGP peer learned path and based on whether the advertisement is directed to a client or a non-client iBGP peer.

  • Publication number: 20120196397
    Abstract: Embodiments of the current invention describe methods of forming different types of crystalline silicon based solar cells that can be combinatorially varied and evaluated. Examples of these different types of solar cells include front and back contact silicon based solar cells, all-back contact solar cells and selective emitter solar cells. These methodologies all incorporate the formation of site-isolated regions using a combinatorial processing tool and the use of these site-isolated regions to form the solar cell area. Therefore, multiple solar cells may be rapidly formed on a single crystalline silicon substrate for use in combinatorial methodologies. Any of the individual processes of the methods described may be varied combinatorially to test varied process conditions or materials.

  • Publication number: 20120074376
    Abstract: Nonvolatile memory elements are provided that have resistive switching metal oxides. The nonvolatile memory elements may be formed by depositing a metal-containing material on a silicon-containing material. The metal-containing material may be oxidized to form a resistive-switching metal oxide. The silicon in the silicon-containing material reacts with the metal in the metal-containing material when heat is applied. This forms a metal silicide lower electrode for the nonvolatile memory element. An upper electrode may be deposited on top of the metal oxide. Because the silicon in the silicon-containing layer reacts with some of the metal in the metal-containing layer, the resistive-switching metal oxide that is formed is metal deficient when compared to a stoichiometric metal oxide formed from the same metal.
