  • BAN system, terminal apparatus, BAN communications method, and computer product
    Patent number: 9560488
    Abstract: A BAN system includes multiple terminal apparatuses connected by wireless communication, where a terminal apparatus of the multiple terminal apparatuses is configured to identify in which direction acceleration has changed, the direction being identified based on a measurement result of a sensor of the terminal apparatus, the sensor being configured to measure acceleration; and to refer to information that specifies corresponding to places where the plurality of terminal apparatuses is to be attached to a body, directions in which acceleration changes when the body performs a given behavior, and determines based on the identified direction, a place where the terminal apparatus is attached to the body.
    Type: Grant

  • Radio equipment controller, base transceiver station, and method for relaying data
    Patent number: 8391801
    Abstract: A Radio Equipment Controller connected, via a plurality of transmission paths, to a plurality of pieces of Radio Equipment for performing communication with a mobile station, and also connected to an upper-level device is provided. The Radio Equipment Controller includes a required time measurement portion that measures, for each piece of Radio Equipment, required time for the Radio Equipment and the Radio Equipment Controller to relay data that has a predetermined size and is transmitted and received between the upper-level device and the mobile station, and a relaying portion that relays target data that is data to be transmitted and received between the upper-level device and the mobile station by delaying a time to transmit the target data based on the required time for the Radio Equipment relaying the target data.
