Abstract: A counter unit, a counter unit control method, a control device, and a control system are provided. A counter unit (10) executes an output to an actuator (40) at a time point when a waiting time indicated by a timing adjustment value (Ta) received from PLC (20) has elapsed since it was determined that an actual measurement value obtained by using a pulse signal has matched with a target value.

Abstract: The present invention suppresses the data size of a data frame to be transmitted to a control device at every control period even if oversampling is performed. A counter unit (10) compresses the data size of sampling data (Sd) indicating a second or subsequent count value (Ct) to the number of bits by which the maximum (Vmax) of a count value countable in one sampling processing can be represented.

Abstract: A clock output unit outputs a synchronous clock signal. A serial data receiving unit receives data representing an absolute position and an encoder sends data in synchronization with the synchronous clock signal. A position conversion unit converts the received absolute position into a current position. The position conversion unit calculates a difference between a last received absolute position and an absolute position received immediately before the last received absolute position. The position conversion unit obtains the latest current position by adding the difference and a current position that was calculated immediately before the latest current position. If the absolute value of the calculated difference is greater than a threshold value, the position conversion unit determines that the last received absolute position has an error.

Abstract: In an abdominal fat measuring device that is a health managing device, vertical and horizontal widths of the abdomen of a subject are measured, and an ellipse defined by such widths is defined as an outer shape ellipse. The abdominal fat measuring device stores in advance an image representing the subcutaneous fat of the abdominal back side as an additional image in association with a proportion of the visceral fat mass and the subcutaneous fat mass. In the abdominal fat measuring device, the corresponding image is extracted from the stored additional images from the measured proportion of the visceral fat mass and the subcutaneous fat mass of the subject, added to the outer shape ellipse, and then a figure representing the measured fat free mass, visceral fat mass, and subcutaneous fat mass is drawn and displayed in the outer shape ellipse.
