A cloud service control device includes a first communicator configured to control communication with a cloud service providing a plant control function of controlling a plant, a second communicator configured to control communication with a first device using service information related to the cloud service, a verifier configured to verify an operation state of the cloud service, a selector configured to select the cloud service on the basis of the verified operation state, and an information transferor configured to transfer the service information between the selected cloud service and the first device.

Cloud service control device having an information transferor configured to limit the transfer of service information, a cloud service control system having a cloud service control device, a related cloud service control method, and a related storage medium

A control network management system for relaying first and second wireless communications comprises a first repeater having a packet control means for writing priority information in a header of communication packet data of the first wireless communication, as received and transmitting the communication packet data with a hash value of the header, added thereto, a second repeater having a packet control means for zero-clearing priority information in a header of communication packet data of the second wireless communication, as received, or changing the priority information to a predetermined value before transmitting the communication packet data with a hash value of the header, added thereto, and a third repeater having a priority control means for applying priority control to the header of the communication packet data received from the first repeater or the second repeater, on the basis of priority information, thereby transmitting the communication packet data to a control system.

An object of the present invention is to realize a camera system suitable for remote monitoring. The present invention is made by making improvements to a camera system that transmits camera image data to a network. The camera system includes a camera head including an image sensor and a sensor controller that controls the image sensor; a video signal processing means that performs video signal processing on image data from the image sensor; and a web server which transmits image data from the video signal processing means as the camera image data to the network, receives control data from the network, and controls at least the sensor controller or the video signal processing means.

Camera system for transferring both image data and an image processing program to transfer the image data to an external device

A moving mirror support device for use with photo-interferometers having first leaf springs arranged in parallel with one end thereof being fixed to a base; a coupling plate fixed to the other ends of the first leaf springs; and second leaf springs arranged in parallel with each of the first springs with one end thereof being fixed to the coupling plate and the other end being fixed to the moving mirror, whereby longitudinal and transverse displacements of the moving mirror can be more accurately controlled.
