Abstract: A synchronous control apparatus capable of switching cam curves with ease and without delay is provided. A cam curve storing unit stores a representation of a first cam curve and a representation of a second cam curve. Before switch-over of the cam curves, a control unit finds a position command value to a driven-side member, after the switch-over of the cam curves, the control unit finds the position command value, and in a switch-over period of the cam curves, the control unit finds the position command value to the driven-side member based on a value obtained by utilizing first data based on the first cam curve or a position of the driven shaft and second data based on the second cam curve to provide a weighted average at each control timing.

Abstract: A digital watermark embedding system generates a watermarked image by providing one or more specific regions in an image, each specific region including two or more base regions symmetric with respect to the centroid, and by embedding a watermark in the image while avoiding the specific region. Further, a digital watermark detecting system detects a watermark in a region other than the specific region, by detecting the shape of the specific region in which no watermark is embedded, calculating the centroid position of the specific region as a centroid, and correcting geometric transformation of the image based on the location in the image that corresponds to one or more calculated centroids.

Abstract: A feedback control method determines a manipulated value to be output to a control target so that a process value obtained from the control target matches a target value. The feedback control method includes: a step of filtering the target value with a filter having a low-pass characteristic; a step of determining the manipulated value in accordance with a deviation between the target value that has been filtered and the process value; and a step of delaying change rate of the target value that has been filtered in accordance with at least one of a fact that the target value is changed and a fact that the determined manipulated value deviates from a predetermined permissible range or approaches the permissible range.

Abstract: A CPU unit of PLC executes a motion control and a sequence control. The CPU unit stores a control program for executing the motion control using a CAM table, and a first CAM table and a second CAM table. When a microprocessor receives a predetermined instruction during execution of the control program, the microprocessor switches the CAM table used in the execution of the control program from the first CAM table to the second CAM table. On the basis of the switching of the CAM table, the microprocessor outputs the execution results of the control program using the second CAM table to an apparatus to be controlled.

Abstract: Regularity information such as time codes embedded preliminarily through an electronic watermark is detected from a predetermined number of pieces of continuous frame data of video content through the electronic watermark. In the case where the electronic watermark is not detected from the predetermined number of pieces of continuous frame data, a non-detection count is calculated, and falsification of the predetermined number of pieces of frame data is determined on the basis of the detected regularity information and the non-detection count. Accordingly, falsification such as deletion, addition, and replacement of video content is detected with high accuracy using the electronic watermark.

Abstract: A selectable operation amount is set as a threshold value according to an input operation amount, where if a determination value obtained by adding the input operation amount and an integrated operation amount or an output error accumulated value is greater than or equal to the threshold value, the threshold value is selected as the output operation amount, and if the determination value is not greater than or equal to the threshold value, a selectable output operation amount close to the threshold value is selected, and the ON/OFF control is performed with the selected output operation amount, while the selected output operation amount is subtracted from the determination value to correct the integrated operation amount, so that the input operation can be substantially output even if it takes an operation amount other than the selectable operation amount values.
