    Abstract: The present invention pertains to a carbon fiber reinforced plastic, and provides a carbon fiber reinforced plastic laminated body that is low cost and superior in moldability, mechanical characteristic balance, and impact resistance. The laminated body has three or more layers, and has the following (B) layer between two layers of a fiber reinforced resin sheet, (B) layer: A resin sheet in which the displacement, in an S-S curve waveform obtained by the following high-speed punching test, from a peak value of the test force (kN) to an 85%—attenuation value is not less than 22 mm. High-speed punching test: Impact absorption energy is calculated by using an impact testing machine in compliance with ISO6603-2 standard. A 100 mm×100 mm test piece is cut out from a sheet having a thickness of 2 mm. The diameter of a striker is 12 mm. the diameter of an opening section of a holding tool is 76 mm, and the impact speed is set to 5 m/sec.

  • Patent number: 7904592
    Abstract: A system and method of managing a network provides for distributed storage and retrieval. In one embodiment, information such as a text message is stored by calculating an actual destination node based on a subscriber identifier and a current addressing function, which corresponds to a current topology of a network. The message is sent to the actual destination node for storage. Messages can be retrieved by calculating a plurality of destination nodes based on a subscriber identifier and a plurality of addressing functions, where each addressing corresponds to a topology of the network at a particular moment in time. In one embodiment, the addressing functions are hash functions.

  • Patent number: 7606252
    Abstract: Systems and methods of processing incoming data provide for receiving incoming data and determining whether to employ stateless routing of the incoming data based on one or more destination hosts associated with the incoming data. In one approach, stateless routing involves storing the incoming data only in volatile memory and withholding confirmation of receipt of the incoming data until confirmation of delivery is received from either the destination host or a downstream router. The determination as to whether stateless routing should be employed can take into consideration historical data for the destination host as well as control data. The determination can also be based on the number of destination hosts.

    Abstract: Online content is selected based at least in part on user profile data. In one embodiment, user profile data, including individual user characteristics, is stored on a profile server. A profile probability may then be calculated for the individual user characteristics. Subsequent online user behavior is analyzed and used to update the profile probabilities for corresponding user characteristics. In one embodiment, specific online content may then be selected and presented based on the user profile data and/or the updated profile probabilities.
