Abstract: The present invention relates to a method for perceiving an event tagging-based situation and a system for same which recognize a plurality of objects by using camera images and apply technology for tracking the movements of the plurality of recognized objects to enable the perception of various situations.

Abstract: A method of controlling an electric power supply system for a mild hybrid electric vehicle includes: a step of executing a sequence for turning on the electric power supply system, wherein when an ignition key is turned on, a voltage of the low voltage battery is boosted and in which, when the voltage of the high voltage power network reaches a preset setting voltage, the high voltage relay is closed; a step of causing the vehicle to travel in a normal mode; a step of limiting entering of a failure mode and checking a connected state of the high voltage relay when a voltage drop occurs; and a step of performing again the sequence, when the high voltage relay is opened, and of resuming the traveling of the vehicle in the normal mode when the high voltage relay keeps closed.

Abstract: A method of controlling fuel injection of a bi-fuel vehicle running on gasoline and liquefied petroleum gas (LPG), and more particularly, a method of controlling fuel injection of a bi-fuel vehicle having an engine running on gasoline and LPG, capable of simultaneously controlling supply systems and injectors of fuels and switching the fuels in response to a fuel switch request based on an injection ratio and an injection time of each fuel is provided. Thus, fuels may be switched stably and efficiently, output reduction and exhaust gas increase due to deviation of an air-fuel ratio while switching fuels may be prevented, and fuels may be appropriately switched. Furthermore, mechanical stress generated while switching fuels may be minimized and stable driving may be provided. Accordingly, the reliability of a bi-fuel vehicle simultaneously using gasoline and LPG may be improved and the competitiveness of bi-fuel vehicle products may also be improved.

Abstract: A method for sharing a backup path in a MultiProtocol Label Switching (MPLS) network, a label switching router (LSR) for setting a backup path in an MPLS network, a system for setting a backup path in an MPLS network, and a recording medium therefor are provided. The method includes the steps of acquiring link configuration information of links included in a working path when the working path is set between a source node and a destination node, and allocating bands for a backup path using the link configuration information when the backup path is set between the source node and the destination node. In the method, an optimal band is allocated to each of links included in a backup path by calculating a band using information, which is obtained during setting of a working path, about at least one other working path sharing links with the working path when the backup path is set, thereby efficiently managing network resources without wasting them.

Abstract: A parallel lookup engine and a method for a high-speed packet forwarding in a network router is provided. The parallel lookup engine includes: multiple lookup engines for performing packet forwarding lookup in parallel in the network router; and a selector for selecting and outputting the longest one of the lookup results performed by the multiple lookup engines. The parallel lookup method includes: (a) step of providing information about a desired key to multiple lookup engines; (b) step of identifying whether the provided key exists in each lookup engine; (c) step of retrieving a prefix tree and returning the information about the desired key in case the desired key exists in each lookup engine based on the result of step (b); and (d) step of selecting and outputting the longest value of the multiple data returned in step (c).

Abstract: A connectionless server for an ATM network carries out routing so that connectionless data generated in a local area network or a terminal is delivered to the appropriate destination. The connectionless server includes a cell header processor for delivering a destination address and an HCT (Header Conversion Table) write address to a destination address processor whenever a BOM or SSM cell is received, and for delivering the cell and an HCT read address to a header conversion processor whenever any cell is received. The destination address processor performs searching and delivers header conversion information (VPIo/VCIo/MIDo) generated from the destination address. The header conversion processor stores the header conversion information from the destination address process and converts the header value of the cell input from the cell header processor using header conversion information stored in a header conversion table.
