  • Patent number: 11902159
    Abstract: A network device may receive, from a source device, an option request that includes a source address of the source device and a destination address of a destination device, wherein the network device is associated with an Internet protocol version 6 (IPv6) network. The network device may identify a map code that is associated with an address translation for traffic associated with the destination device and may determine, based on identifying the map code, a source prefix code and a destination prefix code for the address translation. The network device may determine a source IPv6 prefix and a destination IPv6 prefix for the address translation based on the source prefix code and the destination prefix code and may provide, to the source device, an option response to the option request to permit the source device to use the source IPv6 prefix and the destination IPv6 prefix for the traffic.

  • Patent number: 10999242
    Abstract: This disclosure describes techniques that enable a service provider to synchronize public-private Internet protocol (IP) pairs between a central logging entity (CLE) server that attributes network traffic and network address translation NAT device that logs network traffic. The CLE server includes a communication protocol client communicatively coupled to a communication protocol host. The CLE server, in response to receiving a deregistration message from a registration protocol server, sends a clear request message comprising a private address via the communication protocol client. The deregistration message includes the private address. The NAT device includes the communication protocol host. The NAT device, in response to receiving the clear request message comprising the private address via the communication protocol host, clears a binding that maps the private address to a public address to prevent network address translation between the private address and the public address.

  • Patent number: 4832824
    Abstract: This process is for the reforming of (particularly; the aromatization of and isomerization of) alkanes to produce aromatics isonomal alkanes. Although the process and catalyst parameters can be adjusted to produce a majority of one or the other of the aromatic or isomerate products, the process is especially favorable for the production of a superior gasoline blending component having high octane blending values and containing significant amounts of both aromatics and branched paraffins. Only a small amount of cracking takes place. The process is catalytic and uses a high silica faujasite type zeolite, which contains a catalytic amount of at least one Group VIII noble metal, particularly platinum, within the pores of the zeolite.

  • Patent number: 4127738
    Abstract: A photovoltaic device for the conversion of light (preferably in the visible spectrum) to electrical current consists of at least two electrodes (one of which must be substantially transparent to the light), each electrode being made of different materials and in which one electrode comprises an element that has a work function (generally expressed in electron volts) greater than that of aluminum (e.g. gold or silver) and the other electrode comprises an element that has a work function equal to or less than that of aluminum (e.g., aluminum or magnesium). Sandwiched between and in contact with the electrodes is a photoresponsive organic layer comprising at least one organic compound which, in general, has the capacity to sensitize or de-sensitize silver halides, titanium dioxide, zinc oxide, cadmium sulfide, selenium and polyvinyl carbazole (examples of the organic compounds are the cyanine dyes, especially the merocyanine dyes).

  • Patent number: 4064522
    Abstract: A photocell includes a metallic base electrode, a continuous, crystalline P-type semiconductive selenium layer less than about 50 microns thick, a thin tellurium layer interposed therebetween to metallurgically bond the base electrode to the selenium layer and to form an ohmic contact between the base electrode and the selenium layer, a thin N-type semiconductive cadmium selenide layer contiguous with the selenium layer and forming a photovoltaic heterojunction therebetween, a pellucid layer of at least one cadmium chalcogenide contiguous with the cadmium selenide layer and forming an ohmic contact therewith and a current collecting electrode on the cadmium chalcogenide layer. The sunlight conversion efficiency of the cell is at least about 3.0%. The efficiency can be further improved by doping the selenium layer to improve its conductivity and by providing an N-type layer of cadmium selenide and N.sup.+ cadmium oxide. This can be done by continuously varying the oxygen content of the N-type layer.
