Abstract: A control device for controlling an engine includes main-chamber injecting means (1,3) that supplies a main chamber (8) with fuel; sub-chamber injecting means (2) that supplies a sub chamber (5) with fuel after the main chamber injecting means (1,3) supplies the fuel; estimating means (21) that estimates a degree of knocking serving as indices of an intensity of the knocking and an occurrence frequency of the knocking; and fuel controlling means (22) that carries out, when the degree (N) of the knocking is a first predetermined value (N1) or more, fuel control that reduces a sub-chamber fuel amount representing an amount of fuel supplied by the sub-chamber injecting means (2). By reducing the sub-chamber fuel amount in this manner, the occurrence of knocking can be suppressed, so that the combustion state of a divided-combustion-chamber engine can be enhanced.

Abstract: Provided is a relay server capable of reducing network traffic when collecting large amounts of sensor data from a large number of sensor terminals. A relay server that collects sensor data from a plurality of sensor terminals and uploads the sensor data to a central server via a network includes a data collection unit that collects the sensor data from the plurality of sensor terminals, a relay data creation unit that calculates a presence of spatial overlaps between the collected sensor data, removes overlaps between the sensor data, and creates relay data integrating the sensor data, and an upload unit that uploads the relay data to the central server.

Abstract: The object of the present invention is to provide a technique capable of effectively compressing point cloud data output from the ranging sensor. A data compression apparatus of the present invention includes a data acquisition unit (121) which acquires point cloud data including a plurality of sets each including a direction and a distance from a ranging sensor (11), a data conversion unit (122) which converts directions and distances in the sets into color signals, an image generation unit (123) which generates a bitmap Image by mapping the color signals into a two-dimensional data structure in accordance with the directions, and an image compression unit (124) which applies a predetermined image compression technique to the bitmap image.

Abstract: An image data collecting apparatus includes: an acquisition unit that acquires position information of a plurality of mobile bodies on which a photographing device is mounted, and a selecting unit that acquires, for each mobile body, the position information acquired for the plurality of mobile bodies, information indicating photographing ranges of the photographing devices mounted on the plurality of mobile bodies, and position information of a predetermined object, and selects a mobile body on which a photographing device that outputs collection target image data is mounted from the plurality of mobile bodies on the basis of the acquired information; a transmitting unit that transmits a collection instruction for image data which is a photographing result of the photographing device mounted on the mobile body to the selected mobile body; and a receiving unit that receives the image data transmitted from the mobile body having received the collection instruction.

Abstract: A mixed reality space sharing system is provided with which 3D information regarding a target real space can be shared between a plurality of MR terminals while keeping the information updated, without spending a long processing time. A shared information management server includes: an information management unit for creating a room by associating, with each other, 3D information and anchor information that are transmitted from a first terminal, which is at least one of a plurality of mixed reality terminals, and managing the information; and a sharing unit for transmitting the 3D information and the anchor information to a second terminal different from the first terminal. The second terminal downloads the 3D information and the anchor information transmitted from the shared information management server, and creates a mixed reality space using the downloaded information.
