Redirection of data from an on-premise computer to a cloud scanning service
An on-premise computer in the form of an on-premise gateway receives data transmitted by a client to an intended destination server. The on-premise gateway and the client are on-premise within the same private computer network. The on-premise gateway determines whether or not the data is to be scanned for security checks by a cloud scanning service provided by a cloud scanner on the Internet. The on-premise gateway redirects the data to the cloud scanner when the data is to be scanned in the cloud. Otherwise, when the data is not to be scanned in the cloud, the on-premise gateway forwards the data to the destination server without having the data scanned by the cloud scanner. |

Enabling an Ethernet ring network to scalably support a hub-and-spoke connectivity model
A unique RVID is used for each spoke node to identify traffic flowing from that spoke node to the hub and from the hub to the spoke. Spoke nodes perform MAC learning on any frame containing their assigned unique RVID and only bridge traffic received on the ring to a client port if the traffic contains their assigned RVID. Thus, MAC learning at the spoke is localized to client routes, or to routes of interest that pass through the hub. The hub node learns C-VID/RVID-ringport bindings for traffic on the ring. When a frame is received on the ring, the hub will use the C-VID and RVID to determine the I-SID and forward the traffic onto the external network. When a frame is received from the external network, the hub node will use the I-SID & C-VID to determine the RVID of the spoke node, and then use the C-VID & RVID to determine, from its forwarding database, which ringport should be used to output the frame. |

Inventive aspects include an integrated clock gater (ICG) circuit having clocked complimentary voltage switched logic (CICG) that delivers high performance while maintaining low power consumption characteristics. The CICG circuit provides a small enable setup time and a small clock-to-enabled-clock delay.

Time is “borrowed” from an evaluation window and added to a setup time to provide greater tolerances for receiving the enable signal. |

Q-switched laser device
When an excitation light is entered in a laser medium including a doped (containing rare earth element) YAG, the vicinity of the excitation light entry face is locally heated which generates a birefringence, causing degradation of linear polarization of emitted laser. To avoid such a phenomenon, it was necessary to make the excitation light pulsed and slow down the repetition rate of the pulse. In this device, an undoped YAG is bonded to a excitation light entry face of the laser medium made of a doped YAG. By arranging the YAG <100> axis so as to extend along the optical axis of the laser oscillation system, a linearly polarized pulse laser can be obtained. |

High-power fiber laser employing nonlinear wave mixing with higher-order modes
A high-power fiber laser exploits efficiency and wavelength-conversion of nonlinear wave mixing in a higher-order mode (HOM) fiber providing large effective area and higher-power operation than single-order mode (SMF) fiber. In a “monomode” approach, mixing waves (pump(s), signal, idler) propagate in the same higher-order mode, and in an “intermodal” approach different waves propagate in different modes. The monomode approach can provide high-power wavelength conversion generating output in a desired band where good dopants may be unavailable. The intermodal approach demonstrates coherent combining of outputs of multiple lasers to generate high-power output in a desired band. |

Organic electroluminescent device and production process thereof
An organic electroluminescent device including a substrate, the substrate includes, laminated thereon, an anode layer; an organic structure including at least one light-emissive layer or at least one light-emissive unit having at least one light-emissive layer; a low resistance electron-transporting layer including a mixed layer of an electron-donating metal dopant and an organic compound; an organometallic complex-contained layer including an organometallic complex compound containing at least one metal ion selected from the group having an alkaline metal ion, an alkaline earth metal ion and a rare earth metal ion; a reducing reaction generating layer; and a cathode layer, in that order. At least one of the anode layer and the cathode layer is transparent. The reducing reaction generating layer is a layer produced by depositing on the organometallic complex-contained layer a thermally reducible metal capable of reducing a metal ion in the organometallic complex compound in a vacuum to the corresponding metal, followed by causing an oxidation-reduction reaction therebetween. |

Light-emitting body, light-emitting layer, and light-emitting device
An organic light-emitting element having high efficiency and long lifetime is provided. An organic light-emitting body is provided which includes a host having a high electron-transport property (n-type host), a host having a high hole-transport property (p-type host), and a guest such as an iridium complex and in which the n-type host and the p-type host are located so as to be adjacent to each other. When an electron and a hole are injected to such a light-emitting body, the electron is trapped by the n-type host and the hole is trapped by the p-type host. Then, both the electron and the hole are injected to the guest, and thus the guest is brought into an excited state. In this process, less thermal deactivation occurs and the working rate of the guest is high; thus, highly efficient light emission can be obtained. |

Tridentate platinum (II) complexes
A platinum (II) complex of the general formula (I) or (II), in which Ar1, Ar2, and Ar3 are each independently aryl, heteroaryl, or heterocyclic. Ar1, Ar2, and Ar3 together form a tridentate ligand coordinated to the platinum through atoms X, Y, and Z, respectively, and X, Y, and Z are independently carbon or nitrogen. V is a bridging group or a covalent bond, and W is an anion. In general formula (I) in some cases, Ar1 is an anion and Ar2 and Ar3 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. In general formula (II), in some cases, Ar3 is an anion and Ar1 and Ar2 are neutral; in other cases, Ar1 and Ar3 are neutral and Ar2 is an anion. The complexes are asymmetric. The complexes emit in the UV to near IR range and are useful as emitters for organic light emitting devices. |
