  • Publication number: 20240129217
    Abstract: A stream information setting unit (108) sets, with respect to a plurality of information collection object apparatuses, either a first transmission setting of a first data transmission of which a transmission cycle is designated or a second transmission setting of a second data transmission which uses a predetermined transmission cycle. A telemetry data receiving unit (106) receives data from the information collection object apparatuses by the first data transmission executed according to the first transmission setting and the second data transmission executed according to the second transmission setting performed by the stream information setting unit (108). A measuring unit (103) measures a transmission time of data by the first data transmission. A comparing unit (104) determines whether or not the transmission time measured by the measuring unit (103) exceeds the designated transmission cycle.

  • Patent number: 11831513
    Abstract: A collection unit (132) collects information about at least either of user accommodation status and resource consumption status from plural communications devices accommodating users who receive communications services. An estimation unit (131) estimates an amount of resource consumption of a first user for whom an accommodation device is to be determined. A judgment unit (133) judges whether each of the communications devices satisfies a predetermined restricting condition, based on the information collected by the collection unit (132) and the amount of resource consumption of the first user estimated by the estimation unit (131). A determination unit (134) determines a communications device judged by the judgment unit (133) to satisfy the restricting condition among the communications devices, as the accommodation device for the first user.

  • Patent number: 11817003
    Abstract: A content presentation system includes: a trainee terminal that presents training content to the trainee; a worker terminal used by a worker; a tool recognition device that acquires a work video of the worker and recognizes the tool being used by the worker; a determination device that determines success or failure of the work at a specific stage based on the information about the work tool recognized by the tool recognition device; and a content creation device that creates and updates the training content based on the determination result of the determination device. When the determination result is determined to be the failure of the work by the determination device, the content creation device identifies a portion of the training content corresponding to the specific stage in the work procedure and updates the portion of the training content so as to suppress a factor of the failure.
