Abstract: A control system for an agricultural machine includes a controller configured or programmed to control self-driving of the agricultural machine. In a case where preparation work, including at least one of replacement of an implement to be attached to the agricultural machine, maintenance of the implement, replacement of a part of the agricultural machine, maintenance of the part of the agricultural machine, or replenishment of supplies, is necessary to perform agricultural work, the controller is configured or programmed to move the agricultural machine to a preparation site where the preparation work is to be performed, before the agricultural work is performed.

Abstract: A vehicle cleaner system that includes a single pump and a plurality of cleaners which are connected to the single pump and clean different cleaning target objects with a cleaning medium is disclosed. The cleaning target objects include a sensor which detects information on outside of a vehicle and a cleaner control unit which operates the plurality of cleaners in accordance with input of a signal. The cleaner control unit is capable of operating the plurality of cleaners such that cleaning methods of the plurality of cleaners are different from each other.

Abstract: A management system includes a storage and a processor. While an agricultural machine including an GNSS receiver is traveling, the storage stores GNSS data output from the GNSS receiver and sensing data output from a sensor sensing a surrounding environment of the agricultural machine in association with each other. The processor is configured or programmed to generate and output visualized data, which represents the surrounding environment of the agricultural machine, based on the GNSS data and the sensing data, when reception interference of a satellite signal occurs.

Abstract: A backlight unit includes a light source; a condensing unit that condenses light emitted from the light source; and a diverging unit that diverges the light entering from the condensing unit and that emits the light toward an image display unit of a light transmission type in a head-up display device. For example, the diverging unit is a lens in which both surfaces of an incident surface into which the light from the condensing unit enters as well as an emission surface from which the light is emitted toward the image display unit, are concave surfaces.

Abstract: A management server for a working machine, including: a reception unit that receives a sensor output from a working machine; a regular report creation unit that creates, for each predetermined period of time, a regular report indicating an operation state of the working machine within the predetermined period of time based on the sensor output; an emergency report creation unit that creates at least one emergency report upon detecting abnormality data representing abnormality of the working machine based on the sensor output; an important report creation unit that creates an important report upon detecting predictive data indicating a sign of the abnormality based on the sensor output; and a delivery unit that delivers the regular report, the at least one emergency report, and the important report, respectively, to a regular report delivery target, an emergency report delivery target, and an important report delivery target.

Abstract: A work machine management device includes: a receiving unit that receives, from a work machine, sensor data indicating states of various sections of the work machine, and alarm data indicating that the work machine has determined that an abnormality has occurred in the work machine; and an operating level classifying unit that, based on the sensor data received by the receiving unit, classifies an operating state of the work machine as being any one of a plurality of predetermined operating levels.
