摘要： Provided is a server system robust against a communication path failure. A first server system 2-1 and a second server system 2-2 are respectively installed on a first network 3-1 and a second network 3-2 provided by common carriers different from each other. The first and second server systems are connected to each other by a dedicated line 6. Even when a failure occurs in the first network, communication through the second network can be maintained, and even when a failure occurs in the second network, communication through the first network can be maintained. Further, when a failure occurs in the dedicated line, operations can be performed within each of the first and second networks in a degeneracy mode.

摘要： A wireless station includes at least one oscillator to output a reference signal, and an error calculator to calculate a frequency of the reference signal and calculate a frequency error by subtracting a target frequency of the reference signal from the calculated frequency of the reference signal. The wireless station further includes a modulation data generator to generate modulation data by adding a correction value, varying in negative correlation with the frequency error calculated by the error calculator, to data to be transmitted, and a modulator to conduct frequency modulation on the basis of the modulation data and the data to be transmitted.

摘要： Realized is a communication terminal which, in a case where a status of communication with a low-earth-orbit satellite becomes poor, notifies a user that the status of the communication with the low-earth-orbit satellite is poor. A communication terminal includes: a determining section which determines whether or not an index satisfies a given condition, the index being calculated based on at least one of communication status information indicative of a status of communication between the communication terminal and a satellite, a status of decoding of a signal received from the satellite, and a status of readiness of voice communication based on the signal received from the satellite; and a notification control section which, in a case where the determining section determines that the index satisfies the given condition, controls a notification to be sent to a user of the communication terminal, the notification indicating that the index satisfies the given condition.

摘要： [Problem] To enable the response audio signal of one transceiver to be heard by other transceivers, in cases when a plurality of subordinate transceivers (wireless handset) are present.[Solution] A relaying device is provided with: a wireless apparatus interface having a repeater connected thereto; a signal processing unit connected to the wireless apparatus interface; a network interface connected to a network; a packet processing unit connected to the network interface; and a mixing unit provided between the signal processing unit and the packet processing unit. The packet processing unit reads out an audio signal from a packet inputted from the network interface, and outputs the audio signal as a downlink audio signal. The mixing unit inputs the downlink audio signal into the signal processing unit, and inputs an uplink audio signal into the signal processing unit. The signal processing unit outputs, to the wireless apparatus interface, the downlink audio signal and the uplink audio signal.

摘要： [Problem] To provide an audio communication system in which a relaying device is connected to communication devices via a communication network, the communication devices being terminal devices, and the current location of each terminal device is managed by the relaying device.[Solution] this relaying device is provided with a network communication unit, a control unit, and a storage unit. The control unit divides the communication area of a communication network into a plurality of partial communication areas and stores, in the storage unit, location information indicating which partial communication area each terminal device is in. Upon a partial communication area specifying call from a calling terminal device, the calling terminal device being one of the aforementioned terminal devices, the control unit establishes a communication session in which the calling terminal device and terminal devices in the specified partial communication area participate, and audio signals received from terminal devices participating in the communication session are transferred by the control unit to the other terminal devices participating in the communication session.

摘要： A radio apparatus includes a Man-Overboard detection unit, a control unit and a distress key. The Man-Overboard detection unit outputs a Man-Overboard signal when the radio apparatus has fallen to a water surface or into water. The control unit generates a distress signal including a distress type. A distress key outputs a distress key manipulation signal to the control unit when the distress key is manipulated. When the control unit receives the Man-Overboard signal from the Man-Overboard detection unit, the control unit automatically sets a distress type of the distress signal to Man-Overboard.

摘要： [Problem] To provide a voice communication system which causes a relaying device to manage communication between terminal devices based on the affiliations of the terminal devices, and manage the current positions of the respective terminal devices.[Solution] In a voice communication system, a relaying device relays voice communication of a plurality of section systems. The relaying device stores, with respect to each of the section systems, a plurality of pieces of area information divided on the basis of the communication range of a wireless access point. A terminal device transmits a voice signal to which the identification code thereof is added. When receiving the voice signal from the terminal device, the relaying device identifies a section system to which this terminal device belongs from the identification code added to the voice signal, and identifies an area in which the terminal device is present on the basis of positional information relating to the terminal device. The relaying device transfers the voice signal to another terminal device which belongs to the identified section system and is present in the identified area.

摘要： When operating the radio communication system in a mode for transmitting data for data communication instead of audio signal data, a transmission unit of a radio apparatus generates a packet in which data for data communication is inserted in positions in an audio frame, except for a given position, and in a data frame, and unique data is inserted in the given position in the audio frame. Also, data that is likely to cause an error when the data inserted in the audio frame is decoded by using an audio codec is used as the unique data.

摘要： An electronic device including a submersion detector, illuminants, a lighting circuit, a controller, and an orientation detector. The submersion detector detects submersion of the device and detect retrieval of the device. The illuminants are arranged inside a casing such that at least one of the illuminants is visible from above water when the device is submerged in any submersion orientation. The lighting circuit lights up at least one of the illuminants in response to an input of a lighting signal. The controller generates and outputs the lighting signal to the lighting circuit for a period of time from the submersion at least until the retrieval so as to light up the at least one of the illuminants. The orientation detector detects a submersion orientation of the device. Only the at least one of the illuminants that is visible from above water lights up, in accordance with the detected submersion orientation.
