Abstract: A vehicle includes a processor that includes hardware. When an own vehicle is connected to an external network via a communication mesh network created by vehicle-to-vehicle communication that takes place between multiple vehicles, the processor outputs connection information indicating that the own vehicle is connected to the external network as information that is able to be visually recognized from outside of the vehicle.

Abstract: An information collection device according to the present disclosure is an information collection device that causes a small unmanned aerial vehicle to fly from a departure point to a destination and collects information at the destination using the small unmanned aerial vehicle, and includes a control device that causes the small unmanned aerial vehicle to fly from the departure point to the destination by transmitting a control signal to the small unmanned aerial vehicle by wireless information communication via a vehicle when determination is made that the wireless information communication is able to be executed with the small unmanned aerial vehicle via the vehicle located between the departure point and the destination.

Abstract: A control device for an internal combustion engine including a piston, an oil jet configured to inject oil toward the piston, and an actuator configured to adjust a supply flow rate of the oil to the oil jet. The control device includes an electronic control unit configured to control the actuator such that the supply flow rate under the same engine load and the same engine rotation speed increases as a degree of deterioration of the oil increases.

Abstract: An information distribution system is provided where broadcasting contents are distributed to an IP network using a multicast address for each set of contents, and a home gateway at home connected to the IP network receives desired contents. A program guide server that retains multicast addresses used for each content distribution is also provided in the system, so that a multicast address of a desired contents can be obtained by accessing the program guide server from a program selection terminal via the IP network, and the home gateway can receive the desired contents based on the multicast address.

Abstract: An autotensioner for adjusting the tension of a timing belt used with an automotive engine. It includes a cylinder case filled with a hydraulic oil, a piston partitioning the interior of the cylinder case into a pressure chamber and a reservoir chamber and a push rod having its bottom end coupled to the piston and the top end adapted to protrude from the cylinder case. A spring is provided to bias the piston and the push rod upwardly. The pressure chamber communicates with the reservoir chamber through a channel formed through the piston. A plate-shaped check valve is provided in the pressure chamber to open and close the bottom of the channel. The plate-shaped valve can respond quickly to the fluctuation of pressure in the pressure chamber because of its reduced mass.
