  • Patent number: 8498204
    Abstract: It is provided a data transmission system comprising a transmitter, a repeater and a receiver. The transmitter and the repeater are coupled through a first transmission path and the receiver and the repeater are coupled through a second transmission path. The transmitter, the repeater and the receiver have virtual lanes. The transmitter demultiplexes the transmission data into as many data streams as a number of useable virtual lanes based on useable lane information. The repeater monitors failures of the transmission lanes of the first transmission path and the virtual lanes. The receiver monitors failures of the transmission lanes of the second transmission path and the virtual lanes, selects the useable virtual lanes, sends to the transmitter the useable lane information, corrects a wrong order of the received data streams and a shift of reception point in the virtual lanes, and restores the demultiplexed data streams into the transmission data.

  • Publication number: 20120325731
    Abstract: A wastewater treatment method in an embodiment includes: mixing primary aggregates made of magnetic substances and a dispersion medium to make a suspension; and passing the suspension through a filter to allow the primary aggregates to remain on the filter and to form a secondary aggregate made of an aggregate of the primary aggregates. Further, the wastewater treatment method in the embodiment includes; passing wastewater through the secondary aggregate to remove suspended solids and oil in the wastewater; dispersing the secondary aggregate in a dispersion medium to decompose the secondary aggregate into the primary aggregates and to wash the primary aggregates; and collecting the primary aggregates with magnetic separation.

  • Patent number: 8310995
    Abstract: In a wireless communication system for communicating with a plurality of stations at the same point of time with the same frequency using a Space Division Multiple Access (SDMA), wireless resources are allocated by a first decision unit which evaluates performance of each station obtained when the SDMA is used and which determines periods of time to be allocated to groups of stations formed according to the SDMA technique. Using a first evaluation unit and a second evaluation unit to evaluate performance required by each station and each application, the first decision unit allocates the wireless resources to the stations. It is therefore possible that the wireless resources are efficiently allocated to the stations while preventing an event in which the wireless resources are excessive or insufficient for required quality of service.
