Abstract: A grass management system includes a first moisture-obtaining device to obtain a first moisture value of grass in a mowing operation performed by a mower, a position-detecting device to detect a mowing position of the mower, and a creation supporting circuit to support creation of an operation plan for a working machine based on the first moisture value and the mowing position, the working machine being configured to perform an operation relating to the grass already mowed. The grass management system includes a moisture map creating circuit to create a moisture map of an agricultural field based on the first moisture value and the mowing position. The creation supporting circuit is configured to display the moisture map that is created by the moisture map creating circuit in creating the operation plan.

Abstract: To properly manage data collected by a data collection device even when the data collection device is attached to an agricultural machine different from a specified agricultural machine.

Abstract: An access point device for a work machine is configured to connect a work machine and a mobile terminal via wireless communication. The access point includes a memory, a controller, and a communicator. The memory is to store data of the work machine. The controller is to set a request as a communication identifier to be received by a mobile terminal. The mobile terminal is configured to obtain the data stored in the memory in accordance with the request. The communicator is to transmit the communication identifier to the mobile terminal and to transmit the data stored in the memory to the mobile terminal.

Abstract: Data on agricultural machines can be outputted to mobile terminals easily and properly. A data collection device is provided separately from a control device that controls the operation of an agricultural machine and is connected to a vehicle communication network installed in the agricultural machine, and is removably connected to the vehicle communication network. The data collection device includes a data collection unit for collecting agricultural machine data outputted to the vehicle communication network, an authorization determination unit for implementing authentication with a mobile terminal to determine whether or not the collected data is transmitted to the mobile terminal by wireless communication, and a data communication unit for transmitting data to the mobile terminal by wireless communication when the authorization determination unit authorizes data transmission.

Abstract: The present invention relates to a photographic flash device used with a common still camera in order to photograph a patient's operation under a shadowless lamp. Specifically, the present invention is characterized in that the flash from a stroboscopic unit positioned with the still camera indirectly actuates a flash device housed in the shadowless lamp, thereby causing substantially simultaneous action of a light-emitter of the flash device.

Abstract: The present invention relates to a device for moving lamps used in clinical situations.The moving device has rails and a support which is movable on these rails. The rails are buried in the ceiling and the lamp is suspended from the support. The lamp is movable across an opening provided in the bottom of the rails. A belt is stretched across the total area of said opening to completely seal the opening; the downward support for the lamp passes through this belt; and the belt is movable together with the movement of the lamp.

Abstract: The present invention relates to an apparatus for clinical illumination of an operating room with a number of lamps, which are equally focused on the affected part of a patient's body, characterized in that the horizontal direction on the depth of the light focus from each lamp can be desirably changed by a single manipulation of a simple mechanism without scattering the light from each lamp.

Abstract: A multi-lamp shadowless illumination system which has a plurality of sealed lamp housings and a lamp tiltably mounted in each lamp housing. The lamp housings are mounted on a lamp holding pipe means in a generally horizontal array and in positions with the axes of the lamps directed toward a light axis depending perpendicularly from the central point of the array of lamp housings, the lamps within said housings being tiltable around axes which are perpendicular to the light axis.Operating rods are movable linearly within the pipe means and have one end operatively coupled with the respective lamps for tilting the lamps. Gear means is coupled to the operating rods for driving the rods for simultaneously tilting the lamps to move the focal point of the beams of light from the lamps along the light axis.
