摘要： In an abnormality detector apparatus (4), a signal processor unit (10) performs frequency analysis on data of a current or a voltage in different first and second time intervals to retrieve a first drive frequency corresponding to a maximum peak value of a spectrum in the first time interval and a second drive frequency corresponding to a maximum peak value of a spectrum in the second time interval; adjusts a frequency axis of one spectrum such that the maximum peak values coincide with each other, and calculates an averaged spectrum relating to the adjusted and unadjusted spectra; and retrieve an abnormal peak value equal to or more than a predetermined threshold value at a frequency different from the drive frequency having the maximum peak value based on the averaged spectrum; and determine an abnormal state of the motor (2) depending on presence or absence of the abnormal peak value.

摘要： A monitoring apparatus can start measuring a parameter indicating the state of a monitoring target device in an intended operating state without relying on an external trigger. The monitoring apparatus includes a storage that stores a trigger range usable to determine whether measurement of a parameter indicating a state of a monitoring target device is to be started, a calculator that calculates a parameter associated with an operating state of the monitoring target device, and a measurer that starts measuring the parameter indicating the state of the monitoring target device in response to the parameter calculated by the calculator falling within the trigger range.

摘要： A temperature adjustment device 10 includes a PID calculation part 12, a PID control part 14, and a determination part 15. The PID calculation part 12 calculates a PID value by auto-tuning. The PID control part 14 performs PID control using the PID value. The determination part 15 determines an abnormality in PID control or an abnormality in a target device using the PID value. This allows easy determination of the abnormality in PID control.

摘要： A power generation apparatus can obtain an amount of generated power required for desired signal processing. A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

摘要： A degree of overshooting at the time of response to a target value is suppressed and a settling time is shortened. A temperature control device includes a setting part, a target value filter, and a PID control part. The setting part sets a PID value including a proportional band and integral time and filter coefficients α and β of two-degree-of-freedom PID control. The target value filter calculates an internal target value from a target value of control using the filter coefficients α and β. The PID control part calculates an amount of operation for control using the PID value with the internal target value as an input. The setting part sets the filter coefficients α and β using the target value, an initial value at the start time of control of the target value, and the proportional band.
