Abstract: A communication device mounted to a vehicle acquires an estimated result of a communication resource available in future for a wireless communication between the communication device and a peripheral communication device. The communication device further determines, as a resource pattern, a plurality of combinations of frequencies and time points in future based on the estimated result of the communication resource available in future, the communication device performing the wireless communication with the peripheral communication device at the time points indicated by the resource pattern using the frequencies corresponding to the time points. Then, the communication device transmits, to the peripheral communication device, (i) resource pattern information indicating the resource pattern and (ii) transmission target data at the time points indicated by the resource pattern using the corresponding frequencies.

Abstract: By a radio wave map providing device, a radio wave map providing device, or a non-transitory computer readable medium storing a radio wave map providing program, a radio wave map is stored, a radio wave map request is received; an information amount of reference communication quality information equal to or greater than request communication quality information is compared with an information amount of reference communication quality information equal to or less than the request communication quality information, and a radio wave map reply is generated based on the reference communication quality information having a smaller information amount and reference position information, and transmitted.

Abstract: A radio wave map update device includes a storage unit, a receiving unit, and an update unit. The storage unit is configured to store a radio wave map that contains reference position information indicating a reference position, reference blockage information indicating a reference blockage situation of a communication with a first base station at the reference position, and reference communication quality information of a communication with the first base station or a second base station under the reference blockage situation at the reference position. The receiving unit is configured to receive communication quality information of the communication between a probe information transmitter mounted in a moving body and the first base station or the second base station. The update unit configured to update the reference communication quality information stored in the storage unit using the communication quality information.

Abstract: A moving body communication system includes: a plurality of user apparatuses each used on a moving body; and a server that is configured to distribute, to at least one of the user apparatuses as a requester, commonly used data as data used commonly by the plurality of the user apparatuses, based on a request from the at least one of the user apparatuses. The user apparatus as the requester is configured to execute processing for acquisition of the commonly used data from an already-acquiring apparatus positioned around the requester via a narrow-area communication in response to that acquirability of the commonly used data via the narrow-area communication is notified as a response from the server to a distribution request.

Abstract: A used master disposing apparatus comprises a receptacle for receiving a discharged master, a pressing member vertically movably mounted in the receptacle, and a device for vertically moving said pressing member. The pressing member compresses the master when the pressing member is lowered. The pressing member has a pressing surface, an area of which decreases when it is raised.
