Abstract: An information processing device controls a display for displaying a guide that instructs a user to perform each of a plurality of patterns of motions including translational motions or rotational motions of an inertial sensor that correspond to a first axis and a second axis, which are perpendicular to each other. Based on inertial information and position and orientation information acquired by causing the inertial sensor to perform the plurality of patterns of motions, the information processing device acquires parameters including a degree of correlation between actual inertial values of the inertial sensor corresponding to the first axis and the inertial information corresponding to the second axis.

Abstract: A fine bubble generating nozzle may include a nozzle unit and a baffle. The nozzle unit may include: an inlet; a pressure decreasing portion configured to decrease a pressure of a gas-dissolved pressurized water introduced from the inlet; a first collision chamber disposed downstream of the pressure decreasing portion and including a first collision wall with which the gas-dissolved pressurized water introduced from the pressure decreasing portion collides so that a flow direction of the gas-dissolved pressurized water changes; a second collision chamber disposed downstream of the first collision chamber and including a second collision wall with which the gas-dissolved pressurized water having flowed through the first collision chamber collides so that the flow direction of the gas-dissolved pressurized water changes; and an outlet. The baffle may be disposed outside of the nozzle unit and is disposed at a position facing the outlet.

Abstract: To improve accuracy in a document search for a document that includes a typographical error. A document retrieval device according to one embodiment of the present invention includes a misidentification table storing a correctly identified character string and a misidentified character string. The document retrieval device includes a document searcher. The document searcher obtains a search character string, and retrieves the search character string from both a document and a character string that is obtained by changing the misidentified character string included in the document to the correctly identified character string.

Abstract: A calibration apparatus of an inertial sensor, obtains an angular velocity value from the inertial sensor, derives a distribution of a difference between temporally adjacent angular velocity values concerning a plurality of angular velocity values obtained during a given period, and determines, based on the distribution, whether the inertial sensor is in a motionless state during the given period. Then, if it is determined that the inertial sensor is in the motionless state, the calibration apparatus decides a bias value of the inertial sensor based on the plurality of angular velocity values and corrects the obtained angular velocity value based on the bias value.

Abstract: Based on an image captured by an image capturing unit, a three-dimensional position in a real space corresponding to each of one or more features included in the image is estimated, a candidate region that is a region on a plane of an object existing in the real space is determined as a candidate for a region to which features are to be added based on the estimated three-dimensional position, and a recommended region to which the features are to be added is determined in the candidate region based on the number of features included in a partial region set in the determined candidate region.

Abstract: A network-diagram rendering system for rendering a network diagram including nodes and links as elements of a network configuration is provided with: an index calculation unit (81) which calculates, for each node, an index indicating a degree that the node is a primary node in the network configuration, using network configuration information as information to be obtained from the network configuration; and a primary node coefficient setting unit (82) which sets a primary node coefficient for the node to be higher as the index increases, the primary node coefficient being a value indicating a degree of not changing a rendering position of a network diagram associated with a change in the network configuration.

Abstract: The image display system includes a first image producer producing a first left-eye display image using a left-eye original image that is a left-eye captured image or a left-eye processed image produced therefrom, and producing a first right-eye display image using a right-eye original image that is a right-eye captured image or a right-eye processed image produced therefrom. A first image display unit allows left and right eyes of a viewer to view the first left-eye and right-eye display images. The first image producer produces the first left-eye and right-eye display images each corresponding to an image of a partial area of the original image. A second image producer produces, using at least one of the left-eye and right-eye original images, a second display image corresponding to an image of an area including the above partial area and being wider than that partial area.

Abstract: A flow control valve includes a resin housing body, a valve member, a retainer plate, a drive unit, and a protective wall. The resin housing body is substantially cylindrical. The valve member axially moves back and forth in the housing body to regulate a flow rate of a liquid. The retainer plate is fastened to the housing body at a position axially outward from the bearing to retain the bearing in the housing body. The drive unit drives the valve stem at a position outward from the bearing to move the valve member back and forth. The protective wall surrounds an outer circumferential surface of the housing body at a position radially outward from a portion of the housing body that receives the bearing to form an air layer portion between the protective wall and the outer circumferential surface of the housing body.
