  • Publication number: 20210003057
    Abstract: A method for operating a petrol engine, in which air is introduced into an exhaust tract through which exhaust gas from the petrol engine can flow, bypassing the petrol engine, includes introducing the air into the exhaust tract at a point arranged downstream of a first three-way catalytic converter arranged in the exhaust tract and upstream of a second three-way catalytic converter arranged in the exhaust tract downstream of the first three-way catalytic converter, while the petrol engine is operated with a sub-stoichiometric combustion air ratio, where a desulphurization of the second three-way catalytic converter is effected.

  • Patent number: 10502107
    Abstract: An exhaust gas after-treatment unit for an internal combustion engine, particularly for a motor vehicle, includes a first selective catalytic reduction (SCR) catalytic converter through which the exhaust gas from the internal combustion engine can flow and at least one particle filter for retaining the soot particles from the exhaust gas. The particle filter, which is located downstream from the first SCR catalytic converter, is equipped with a heavy metal and precious metal free catalyzing coating which oxidizes the soot particles retained by the particle filter, where downstream from the particle filter there is a second SCR catalytic converter through which the exhaust gas can flow.

  • Patent number: 10462162
    Abstract: Methods and systems for detecting malicious processes. Methods described herein gather data regarding process locations and calculate one or more inequality indicators related to the process paths based on economic principles. Instances of inequality with respect to process paths may indicate a path is uncommon and therefore the associated binary is used for malicious purposes.

  • Patent number: 6801941
    Abstract: A method of assigning a unique IP address to a user of a mobile communication device in an OBS network allows for the dynamic assignment of IP addresses to users entering the OBS network. The OBS network includes a plurality of interconnected OBSs where each of the OBSs includes a user database including an OBS identifier, user identifier, assigned IP address, MAC hardware address, and beam identifier for each user in the network. The OBS network also includes a master ticketing authority that maintains a database of unique IP address that may be assigned to users entering the network, a gateway, a master routing database, and at least one mobile communication device in contact with an OBS. Users in the network are also authenticated through the transmittal of encrypted random numbers between a user authentication site and a mobile communication device.

  • Patent number: 6704283
    Abstract: A method of transmitting a message from a source node to a destination node in a small, wireless network having up to N nodes in which each message has appended thereto concise network configuration data which eliminates the need for routing protocols without adding significant overhead to the network communications. The method includes the steps of creating for each node a route table containing a count of the number of transmission hops necessary to reach each destination node and a node number of a neighboring node forming a next link in a chain of hops to each destination node, where the node number identifies a unique bit in an N bit address mask. Routing data is appended to the message data which includes an N bit destination word identifying the destination node or nodes, an N bit route word including a logical OR of the address mask of the relay node or nodes, and a route update message identifying what the current node knows about the network configuration.
