A retinal prosthesis system can comprise: a flexible substrate; a nanowire light detector which is placed on the substrate, and comprises one or more nanowires of which the resistance changes according to the applied light; one or more micro-electrodes which are placed on the substrate, are electrically connected to the nanowire light detector, and come in contact with retinal cells; and an electric power supply source for applying electric power to the nanowire light detector and the micro-electrodes. The retinal prosthesis system can be implemented into a very thin and flexible substrate type high resolution retinal system by manufacturing a nanowire light detector on a substrate in which micro-electrodes are implemented.

A method for managing an Ethernet ring network of a VLAN-based bridge is provided that includes: registering a major-ring VLAN ID (VID) in a ring port filtering database of a ring protection link owner node in accordance with a request for registering the major ring VID from an Ethernet Ring Protection controller mounted on the ring protection link owner node of a major ring; delivering, by the ring protection link owner node, a VID registration message to other nodes which belong to the major ring through a ring port; receiving the VID registration message through the ring port and registering the major ring VID in a ring port filtering database of each node itself, by each node belonging to the major ring; and delivering, by each node belonging to the major ring, the VID registration message to other nodes belonging to the major ring through the ring port.
摘要:
A method for mitigating interference at a small base station in a hierarchical cell structure is provided. In the method, the small base station checks a sub-frame allocated to macro user equipment by using a downlink signal received from a macro base station when an interference candidate user equipment list is received. The interference candidate user equipment list contains information on the macro user equipment adjacent to a femto cell controlled by the small base station. Then the small base station allocates other sub-frame to femto user equipment located in the femto cell by avoiding the sub-frame allocated to the macro user equipment.
摘要:
A bandwidth aggregation system for providing wideband communication services by aggregating multiple bandwidths and a transmission band determination method for the bandwidth aggregation system are disclosed. T bandwidth determination method includes computing weights of the multiple bandwidths based on resource allocation distributions of the individual bandwidths, and selecting one of the multiple bandwidths for establishing a connection between a base station and a mobile station based on the weights of the multiple bandwidths.

A coating composition for zinc- and zinc alloy-coated steel sheets includes: 1 to 30% by weight of hypophosphorous acid, 0.1 to 10% by weight of manganese, 0.01 to 5% by weight of a polyvinyl compound, zinc oxide and the balance of water, and further comprises 20% by weight or less of alcohol, when necessary, wherein the zinc oxide is included in such a content that, when 50 Ml (milliliters) of the coating composition is neutralized and titrated with 0.1N NaOH, the NaOH used for the neutralization titration is present in an amount of 10.0 Ml (milliliters) or less, and a content of free acid in the coating composition is adjusted to such an amount that, when 50 Ml (milliliters) of the coating composition is neutralized and titrated with 0.1N NaOH, the NaOH used for the neutralization titration is present in an amount of 10.0 Ml (milliliters) or less. The coating film formed on the steel sheet using the coating composition shows excellent properties such as lubricating property, adhesion and coating removal property, and also has a fine surface appearance.
