  • Information processing device and method of testing
    Patent number: 10387233
    Abstract: An information processing device includes a first port and a processor coupled to the first port and configured to transmit, via the first port, a first signal to a first device coupled to the first port, cause a second device coupled to the first port to determine whether a failure is present in the first port when the information processing device does not receive a first response signal in response to the first signal, and determine that the failure is present in the first device when the second device does not determine that the failure is present in the first port.
    Type: Grant
    Filed: May 30, 2017
    Date of Patent: August 20, 2019
    Assignee: FUJITSU LIMITED
    Inventors: Tsukasa Kinjo, Satoshi Kubota, Junichi Ogawa
  • Diagnosis device, diagnosis method, and non-transitory recording medium storing diagnosis program
    Patent number: 10142169
    Abstract: A diagnosis device includes: a processor that executes a diagnosis program; and a memory that stores the diagnosis program, wherein the processor, based on the diagnosis program, performs operations to: collect a data transmission variable set by a data transmission path characteristics from a transceiver device on a diagnosis target path; and perform diagnosis for the diagnosis target path with reference to diagnosis reference information that includes a value of the data transmission variable and determination information associated with each other, based on collected data transmission variable.

  • Electronic device, communication control circuit, and communication control method
    Patent number: 10108574
    Abstract: An electronic device includes a communication unit configured to be connected to another communication unit via a first number of transmission paths, where the first number is greater than or equal to two, and a control unit configured to determine communication quality in each of the first number of the transmission paths at a time of initiating communication with the other communication unit and to select a second number of transmission paths, where the second number is less than the first number, in descending order of the communication quality from among the first number of the transmission paths, thereby causing the communication unit to perform communication by using the second number of the transmission paths, which have better communication quality.
