Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.

Abstract: It is an exemplary object of the present invention to provide an optical wireless device that easily and stably adjust and fix an optical axis. An inventive optical wireless device includes a communication part for optical communications. and an attachment part for rotatably supporting the communication part and fixing the communication part at a predetermined angle.

Abstract: The optical wireless communication device 1 is provided with a transmitting unit 102 outputting a light such as a laser light for optical communication. Beside the transmitting unit 102, the optical wireless communication device 1 is also provided with a laser pointer 24 emitting a light for optical axis adjustment. Further, the front surface of the optical wireless communication device 1 has a sight 401 where a light for an optical axis adjustment irradiates to allow proper adjustment of an optical axis. The optical wireless communication device 1 allows optical axis adjustment to be quick and easy in the configuration where a position of a device of one side is adjusted for an optical axis alignment with the device of the other side by checking the lighting of the LED 22 in the other side.

Abstract: An optical wireless communication device for performing communication by laser light. A primary light-emitting unit emits a laser light and a processing unit adjusts divergence of the laser light. A laser light adjustment method is provided wherein an optical wireless communication device measures a distance to an object which is to be irradiated with laser light and adjusts divergence and/or output power of the laser light based on the measured distance. Further, an optical wireless communication device, an optical wireless communication system, a management apparatus and a computer-readable medium storing a management program are provided, which allow a user to easily check a communication status of the optical wireless communication device.
