摘要:
The present invention is related to a cyclopentaphenanthrene-based compound and an organic electroluminescence device using the same. In particular, the cyclopentaphenanthrene-based compound offers several advantages, including easy processibility, high solubility, superior color purity, color stability and thermal stability. Moreover, the cyclopentaphenanthrene-based compound may be used not only as a material for forming an organic layer of an organic electroluminescence device, particularly, a light-emitting layer, but also as a material of an organic pigment or nonlinear optical substance.

Biphenyl derivatives having four substituents at meta positions of biphenyl structure, which is a core molecular structure, and organic electroluminescent devices using the biphenyl derivatives. The biphenyl derivatives are phosphorescent host compounds having amorphous structures and have excellent thermal stability and high solubility in general organic solvents, is easily to use for solution (or wet) process, and can easily energy-transfer to a metal complex used as dopant. The biphenyl derivatives also can be used as blue host materials of phosphorescent emission layer, hole transporting materials, or a hole injecting materials of an organic electroluminescent device.

A method and a system for using the method are provided. The method and system allow a low power device having an asymmetric link to access a wireless network to exchange beacons with any one of a plurality of normal power devices in the wireless network. The method includes the steps of confirming whether the low power device has the asymmetric link with the normal power device, when the low power device receives a beacon of the low power device based on the received beacon; negotiating with at least one relay device so that the low power device requests a relay with respect to the asymmetric link, when the low power device has an asymmetric link with the normal power device; and at least one relay device noting a result of the negotiation to the low power device and a normal power device with which the low power device is intending to communicate, based on the result of the negotiation.

摘要:
A method and apparatus is provided for setting multiple paths between wireless nodes of an ad-hoc network including a source node, a relay node and a destination node that receives a message from the source node via the relay node. The multi-path setting method and apparatus includes receiving previous hop address information, and determining whether a wireless node that receives the previous hop address information is included in an insulating region, based on the previous hop address information.
摘要:
An apparatus, method and system are provided for routing a broadcast data frame in a mesh network with multiple mesh portals. In the mesh network, every mesh point selects and registers its default mesh portal. A mesh portal enters its address in a destination address field of a broadcast data frame received from outside of the mesh network and broadcasts the data frame to inside of the mesh network. The mesh point processes a received broadcast data frame relating to its registered mesh portal, thereby preventing the broadcast data frame from being redundantly transmitted in the mesh network.
摘要:
A dispersion shifted optical fiber includes: a first core having a constant refractive index within a predetermined radius from the center of an optical fiber, a second core which covers the first core and has a refractive index which decreases from the refractive index of the first core with an increase in its radius, and a cladding which covers the second core and has a refractive index smaller than the minimum refractive index of the second core. Accordingly, the core structure of an optical fiber is controlled, and the optical fiber has a refractive index distribution being a complex of a staircase type having low dispersion and a triangular type having low loss, thus resulting in an optical fiber having low dispersion and low loss.
