A control apparatus which controls a force applied to an object, includes a driver configured to apply the force to the object, an estimator configured to estimate, based on information related to a state of the object, an estimated value of a disturbance force to be applied to the object, a corrector configured to correct, based on the estimated value, a command value provided to the driver so as to reduce an influence of the disturbance force, and a determiner configured to execute processing for determining a plurality of parameter values to be used by the estimator to obtain the estimated value based on the information.

Control apparatus, imprint apparatus, and method of manufacturing article

An imprint method of molding an imprint material on a shot region of a substrate using a mold, includes aligning the shot region and the mold in a state where the imprint material and a pattern region of the mold are in contact with each other; and curing the imprint material by irradiating the imprint material with curing light after the aligning. The aligning is controlled so as to include an overlap period during which a period during which deformation light used to deform the shot region is applied to the substrate through the imprint material and a period during which polymerization light used to increase a viscosity of the imprint material is applied to the imprint material overlap each other. The polymerization light to be applied to the imprint material is controlled in accordance with the deformation light to be applied to the imprint material during the overlap period.

The present invention allows to estimate a continuous surface that defines a boundary surface of an object using image data, even if the image data was acquired by an imaging method in which image information on the boundary surface of the object is limited. An image processing apparatus according to the present invention includes a calculating unit that calculates a brightness gradient of a voxel group constituting volume data which represents a reconstructed image, and an estimating unit that estimates by using the brightness gradient a continuous surface which defines a boundary surface of an object corresponding to the volume data.

Aspects of the invention are directed to a medical image display apparatus for displaying a thumbnail image corresponding to medical image data. The medical image data can be displayed in a display area upon selection of the thumbnail image. A display method of the medical image data in the display area can be determined, based on a designated position in the thumbnail image when the thumbnail image is selected by a user. Medical image data is displayed in the display area, according to the determined display method.

A positioning apparatus, which positions a stage, includes a measurement system that measures a position of the stage. The measurement system includes a plurality of measuring devices that are spaced apart from each other along a first direction and measure a position of the stage in a second direction. A switching unit switches between the measuring devices to measure the position of the stage when the stage moves in at least the first direction. A correction unit corrects, based on an acceleration of the stage, the value measured by the measurement system. When the switching unit switches between the plurality of measuring devices, the correction unit corrects, based on a value obtained by the correction, a value measured by a measuring device after the switching.
