Abstract: An optical device includes: a light guide plate having a group of optical-path deflectors configured to change the optical path of light from a first light source to form an image in the space within a first angle range, and change the optical path of light from a second light source to form an image in the space within a second angle range, wherein the first angle range and the second angle range are separated from each other or adjoining each other.

Abstract: The management server causes an output section to output a startup date and time, shutdown date and time, minimum, maximum, and average values, and an occurrence count and durations of a predetermined event, for each of the operation time periods from the startup to shutdown in a unit of the remote monitoring terminal device, and causes the output section to output the startup date and time, shutdown date and time, and a movement locus of the mobile work vehicle or vessel based on the location information, for each of the operation time periods from the startup to shutdown in the unit of the remote monitoring terminal device.

Abstract: In a remote server that receives from a work machine or a vessel, machine identification information as information for identifying the work machine or the vessel and predetermined operation data, a service center in charge of the work machine or the vessel is identified based on the machine identification information, a repair part required in the service center and a repair timing of the repair member are determined based on the operation data received from the work machine or the vessel and on any one of a regular maintenance history received as appropriate and the regular maintenance history received from the work machine or the vessel, and the service center is notified that the repair part is required at a timing earlier than the repair timing determined by a predetermined period.

Abstract: In a remote server that receives from a work machine or a vessel, machine identification information, identifying the work machine or the vessel, and predetermined operation data, at least one of a managing entity of the work machine or the vessel and a sales entity in charge of the managing entity is identified based on the machine identification information, a base buying price of the work machine or the vessel is calculated based on the predetermined operation data received from the work machine or the vessel, and any one of a regular maintenance history input as appropriate and a regular maintenance history received from the work machine or the vessel, and the base buying price calculated is set to be viewable in at least one of the managing entity and the sales entity when a predetermined period elapses after a predetermined counting start day.

Abstract: Disclosed is a remote monitoring terminal device for a mobile work vehicle or vessel, capable of informing the user of maximum, minimum, and average values for each sensor and a turn-on count of a switch. The remote monitoring terminal device includes: connection terminals; a data abridging control section for computing minimum, maximum, and average values of data collected over a period from a startup to the latest data acquisition and of actual operation data on actual operation and an occurrence count and durations of a predetermined event, on the basis of operation-state data acquired via the connection terminals and stored in a data storage section; and a communications section. In response to a manual turn-off of a startup switch of the mobile work vehicle or vessel, the data abridging control section transmits data stored in the data storage section, to the remote monitoring device via the communications section.

Abstract: There is provided a managing server for a remote monitoring system for communication with a remote monitoring terminal device which acquires a startup date and time via a GPS satellite system upon a startup. In response to a reception from the remote monitoring terminal device of an indication that the remote monitoring terminal device failed to acquire date and time information via the GPS satellite system upon a startup of the remote monitoring terminal device, the managing server transmits date and time information generated from a date and time of reception of the indication to the remote monitoring terminal device.
