  • Publication number: 20230399718
    Abstract: A method and system for recovering a high yield of low carbon ferrochrome metal from chromite ore and low carbon ferrochrome metal produced by the method. A thermochemistry calculated mixture of feed materials including aluminum granules, burnt limestone, and chromite ore are provided into a DC plasma arc furnace. The aluminum granules are produced from aluminum scrap. The feed materials are heated upon entering the furnace free board through a feed mix injection system, whereupon the aluminum in the aluminum granules produces an exothermic reaction reducing the chromium oxide and iron oxides in the chromite ore to produce molten low carbon ferrochrome metal with molten slag floating thereon. The molten low carbon ferrochrome metal is extracted, solidified into ingots, crushed into coarse pieces or fines of low carbon ferrochrome metal product. The molten slag is extracted, quenched and solidified into slag particles product.

  • Publication number: 20210278209
    Abstract: A method 20 and system 10 monitor road condition, by providing, for portions (14.1-14.m) of a road 12, an approximation 210 of a roughness figure in accordance with a roughness index. The method 10 includes receiving speed data 208 of a first vehicle 16 travelling along each of the portions of the road 12 and receiving, from a measuring device 18 carried on the first vehicle 16, measured acceleration data 204 of the device 18 perpendicular to the road 12 surface. The acceleration data 204 is processed to provide a parameter value 206 relating to the acceleration data 204 for each of the portions of the road 12. A first speed-based conversion equation and the speed data 208 is utilized to convert the parameter 206 into the approximation 210 of a roughness figure for each of the portions of the road 12, in accordance with the roughness index.

  • Patent number: 10979386
    Abstract: A method includes receiving a request for an edge cache address, and comparing a requestor address to an anycast group. The method can further include providing an anycast edge cache address when the requestor address is in the anycast group. Alternatively, the method can further include determining an optimal cache server, and providing a unicast address of the optimal cache server when the requestor address is not in the anycast group.

  • Patent number: 10757173
    Abstract: A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.

    Abstract: A system for providing content includes a plurality of content delivery servers and a routing control module. Each of the content delivery servers is configured to receive a first request from a client system sent to an anycast IP address for the content, and to provide a first portion of the content to the client system. Each of the content delivery servers is further configured to receive a second request from the client system sent to the anycast IP address for a second portion of the content, and to provide the second portion of the content to the client system. The routing control module is configured to modify the routing of the anycast address from a first content delivery server to a second content delivery server.

  • Patent number: 10419992
    Abstract: Methods and apparatus to migrate a mobile device from a first virtual private mobile network to a second virtual private mobile network are disclosed. An example apparatus includes a processor and a memory including instructions that cause the processor to perform operations including determining, based on a set of latency routing rules, that a communication transmitted via the first virtual private mobile network is a latency sensitive communication. In response to determining the communication is a latency sensitive communication, the mobile device that originated the latency sensitive communication is identified. The mobile device is communicating via the first virtual private mobile network. Example operations also include migrating the mobile device from the first virtual private mobile network to the second virtual private mobile network wherein the second virtual private mobile network is configured to reduce the latency of the latency sensitive communication.

  • Patent number: 10069799
    Abstract: Methods and apparatus to configure virtual private mobile networks are disclosed. Example methods include provisioning a virtual private mobile network within a wireless network, and, after provisioning the virtual private mobile network, determining whether a first communication from a user equipment matches a security event profile. When the first communication matches the profile, the example methods include transmitting, from the wireless network via a first base transceiver station, an instruction to cause the user equipment to be communicatively coupled to the virtual private mobile network. The example methods further include instructing the user equipment to transmit a second communication through a second base transceiver station that is physically separate from the first base transceiver station and through the virtual private mobile network. In the example methods, the virtual private mobile network is isolated in a wireless spectrum from other portions of the network.
