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: The present invention enables distribution of a message to a movable device, in publish/subscribe communications via a broker consisting of multiple stages. In an edge server, a message transmission and receiving unit receives, from a first broker, a message transmitted from a management device and directed to a device, or a message for which re-distribution was requested by another edge server and which is directed to the device. The message transmission and receiving unit transmits the received message to a second broker. When notified of a failure to distribute the message to the device, a request destination determination unit determines another edge server to serve as a re-distribution request destination. A re-distribution request unit transmits, to the first broker, the message directed to the device.

Abstract: Voltage is applied between electrodes (14a, 14b) under UV irradiation to perform a UV excitation poling, thereby producing microcrystal particles at a core unit (10a). Accordingly, second-order optical nonlinearity is developed at the core unit (10a) of an optical fiber (10). Under a high-temperature condition, a second-order optical nonlinearity can be imparted by a comparatively low-voltage UV excitation poling when a second-order optical nonlinearity decreases.

Abstract: A Ge-added SiO2 thin film (12) is formed on a glass substrate (10), and metal film (14) is formed thereon (S11 to S13). By etching the metal film (14), a pair of electrodes (14a, 14b) mutually opposed at a predetermined interval is formed(S14). An insulating thin film (16) is formed on the insulating film (12) and the electrodes (14a, 14b) (S15). While applying ultraviolet radiation, a high voltage is applied between the electrodes (14a, 14b) to perform ultraviolet excitement polling to impart an optical nonlinearity to a channel region (18)(S16). By controlling the voltage application to the channel region (18) having the optical nonlinearity, the light transmitted through the channel region (18) is controlled. Thus, an optical nonlinear waveguide for propagating single mode light is formed on a glass substrate.

Abstract: A metal film (12) is formed on the surface of a glass substrate (10) and etched to form a pair of electrodes (12a and 12b) which face each other with a certain gap therebetween (S11˜S13). The substrate (10) is doped with germanium, etc, by using the electrodes (12a and 12b) as a mask to form a core part (14, S14). Then a high voltage is applied between the electrodes while ultraviolet radiation is applied and the core part (14) is subjected to ultraviolet-driven boring to give the optical nonlinearity to the core part (14, S15). The voltage application to the core part (14) having the optical nonlinearity is controlled to control a light transmitting through the core part (14).
