Content request pattern-based routing system
A pattern-based content request routing system is described herein that can route content requests according to user and/or user device behavior. For example, the routing system can cause requests for byte-heavy content to be routed to content delivery networks (CDNs) that have a sufficiently large cache width—even if such CDNs are not the geographically-closest CDNs to the source of the requests—to reduce the negative impact on content retrieval latency for other user devices that may be requesting other content. In particular, CDNs may store access logs that indicate the types of content requested by various user devices. The routing system can retrieve and analyze the access logs to identify patterns of requests. The routing system can then evaluate the properties of various CDNs, determine which CDNs may be suitable for the identified patterns of requests, and instruct a DNS server to route user devices accordingly. |

Electric generator with a rotational resistance avoidance feature
The electric generator with the rotational resistance avoidance feature in the present invention comprises a rotating set of magnet parts interposed between at least two rotating sets of conductor coil parts, which are respectively installed on opposite sides of the rotating set of magnet parts. The diameters of the rotating sets of conductor coil parts are configured to be larger than the diameter of the rotating set of magnet parts. The rotational speed of the conductor coil parts and the magnet parts are therefore different, which causes the induction of the electromotive force within the conductor coils by way of variation of the magnetic field. When the mechanical power input is applied only on the rotating set of magnet parts and the electromotive force induced in the conductor coil, which has been connected to a load, is applied to a load; the electrical current will induce the conductor coil itself to generate magnetic polarities which are similar to the original magnetic polarities of the permanent magnet. The sets of conductor coils are pushed by the said pushing force to be continuously rotated in a clockwise direction (freely rotated without being driven by the mechanical power input). The rotating set of magnets in the middle is also continuously rotated by the mechanical power input. With this configuration, the rotational resistance can be avoided. Therefore, the additional mechanical power input is not necessary (rather, only a partial increase is required), and the electrical power can be generated by converting the magnetic energy stored in permanent magnets, to be supplied to the load. |

Electrode, method for producing said electrode, electricity storage device provided with said electrode, and conductive carbon mixture for electricity storage device electrode
Provided is an electrode which gives an electric storage device that has high energy density and good cycle life. This electrode for an electric storage device is characterized by having an active material layer that contains: an electrode active material particle; and a paste-like conductive carbon that is derived from an oxidized carbon obtained by giving an oxidizing treatment to a carbon raw material with an inner vacancy and covers a surface of the electrode active material particle.
