Abstract: An intestinal activity regulation device includes a regulator that performs a regulation process of regulating intestinal activity of a target person based on the state of the intestinal activity detected by a detector that detects the state of the intestinal activity of the target person.

Abstract: An external communication unit receives, from a server, update information including information indicating an update target device whose software is to be updated among devices and information indicating a generation source device among the devices, the generation source device being installed with generation source software that is a source for generating update data to be used for updating update target software installed in the update target device. An update data generating unit generates, on the basis of the update information, the update data using the generation source software installed in a host device of the update data generating unit, when the host device is the generation source device. A software update unit updates, on the basis of the update information, the update target software installed in a host device of the software update unit using the generated update data, when the host device is the update target device.

Abstract: A surrounding information obtaining unit determines whether a first vehicle has traveled on a different road than a road on which a host vehicle travels, on the basis of information indicating roads and a facility present around the host vehicle and a travel state of the first vehicle. A difference checking unit checks whether a target road determined to have been traveled by the first vehicle is included in host vehicle map information. A wireless communication unit inquires whether an unknown target road confirmed not to be included in the host vehicle map information is included in master map information in a server device. When the unknown target road is included in the master map information, the wireless communication unit receives updating map information including the unknown target road from the server device. A map updating unit updates the host vehicle map information using the updating map information.
