Fuzzy whitelisting anti-malware systems and methods
In some embodiments, an anti-malware system accounts for benign differences between non-malicious data objects, such as differences introduced by compilers and other polymorphisms. A target object is separated into a multitude of code blocks, and a hash is calculated for each code block. The obtained set of target hashes is then compared against a database of hashes corresponding to code blocks extracted from whitelisted objects. A target object may be labeled as whitelisted (trusted, non-malicious) if it has a substantial number of hashes in common with a whitelisted object. Objects which are slightly different from known whitelisted objects may still receive whitelisting status. By allowing a certain degree of mismatch between the sets of hashes of distinct objects, some embodiments of the present invention increase the efficiency of whitelisting without an unacceptable decrease in safety. |

Method and apparatus for simulating IP multinetting
IP Multinetting on a local area network is simulated by performing VLAN translation at a port connecting to the local area network. This allows IP addresses from multiple subnets to be associated with a single VLAN on the Local Area Network (LAN), while allowing the core switch to process the packets with a one-to-one correspondence between IP Subnet and VLAN. When a packet is received from the local area network at an IP multinetting port, the VLAN ID will be read to determine if the packet contains the IP Multinetting VLAN ID. The IP Subnet address will also be checked to see if the packet is associated with an IP Subnet that is part of the Multinetting. If so, the multinetting VLAN ID will be changed to an IP Subnet specific VLAN ID before the packet is processed by the core switch. |

Reducing fragmentation of packets in a networking environment
Automated techniques reduce packet fragmentation in a communications network environment, including a networking environment that uses tunnels. In a tunneling environment, a tunnel endpoint evaluates whether tunnel processing for an outbound packet will cause the packet to exceed a particular size such as a message transmission unit (“MTU”) size, which in turn would lead to error processing and/or fragmentation of the packet. Similar MTU and packet mismatch may occur in a system across the virtual machine and the hypervisor, a networking stack and the physical MTU possible on the network. If so, the tunnel endpoint or the network driver simulates an error condition and returns an error message to the protocol stack that prepared the packet, so that the packet size can be reduced before the packet is actually sent on the tunnel. Existing functionality is leveraged to perform the size reduction, thus obviating the need for administrator intervention. |

If a feasible path cannot be identified based on the ancillary information, supplemental information regarding nodes further along the potential path is assessed to provide a basis for inferring the nodes that may provide a feasible path.

Low latency spatial multiplexing MIMO decoder
Wireless communication systems normally employ Multiple Input Multiple Output (MIMO) transmission and reception schemes to increase performance and the data rate of the system. Spatial Multiplexing (SM) is used in MIMO systems for increasing the data rate of the communication system by transmitting multiple data symbols on different antennas at the same time on the same frequency.

Sorting operations are generally difficult to parallelize leading to increased processing latency.

A heater block according to the present invention comprises a light-emitting lamp; a concave reflecting member that is placed opposite the lamp and has a concave reflecting surface at one surface faced with the lamp; a lens module that is inserted into the concave reflecting member and has at least one lens; and a flat reflecting member that is placed opposite the lens module. According to embodiments of the present invention, light emitted from the lamp is reflected by the concave reflecting member. Then, light and heat are collected from the reflected light by the flat reflecting member and the lens module and are irradiated on a substrate. That is, light having energy greater than a conventional manner is irradiated on the substrate to enhance the instant heating temperature and temperature increasing rate of substrate and to increase a heat-focusing area. Therefore, it has an advantage that the productivity of semiconductor or display device manufacture that requires a rapid thermal process is improved. |

Mergeable semiconductor device with improved reliability
A device includes a semiconductor substrate, source and drain regions disposed in the semiconductor substrate, having a first conductivity type, and laterally spaced from one another, and a composite body region disposed in the semiconductor substrate and having a second conductivity type. The composite body region includes a first well region that extends laterally across the source and drain regions and a second well region disposed in the first well region. The drain region is disposed in the second well region such that charge carriers flow from the first well region into the second well region to reach the drain region. The second well region includes dopant of the first conductivity type to have a lower net dopant concentration level than the first well region. A pocket may be disposed in a drain extension region and configured to establish a depletion region along an edge of a gate structure. |
