Abstract: A sensor device includes a plurality of electrode chambers, a measurement chamber, and an accommodation chamber which are connected in annular relationship permitting expansion and contraction. Each of the plurality of electrode chambers has a measurement electrode. The measurement chamber has a biological potential measurement circuit which is connected with each measurement electrode via electrically conductive wiring for measuring biological potential of the user by using the measurement electrode. The accommodation chamber has an internal protrusion. The wiring which connects at least one measurement electrode and the biological potential measurement circuit is provided around the protrusion, the wiring having a length which enables longitudinal feeding in accordance with an amount of elongation when the sensor device is elongated. A maximum clearance S between the accommodation chamber and an adjacent chamber is greater than a maximum clearance R between any two adjacent chambers.

Abstract: A power generation equipment monitoring system includes a receiver and a determining processor. The receiver acquires, from a measuring device that measures output currents of power generation equipment that converts rotational energy of a rotor thereof into electric energy to output AC voltage with a reference frequency, waveform data representing waveform of the output currents. The determining processor determines presence and absence of a malfunction in a rotary block that applies motive power to the rotor of the power generation equipment, according to the waveform data acquired through the receiver. The determining processor determines the presence and absence of the malfunction based on a component of at least one specific frequency arranged at one or more intervals according to a rotational speed of the rotor from the reference frequency on a frequency axis in a frequency spectrum of the output currents.

Abstract: The condition monitoring system includes an acquisition unit and a generation unit. The acquisition unit acquires waveform data from a measuring device to measure an electrical signal that is either output or input of a converter. The waveform data represents a waveform of the electrical signal. The generation unit generates, based on the waveform data, analysis data to monitor the condition concerning the converter. The generation unit obtains, by frequency analysis, a plurality of combinations, each including a value of a frequency and a value of a feature quantity that is either intensity or phase, based on the waveform data when a value of the drive frequency varies and thereby generate the analysis data having at least three variables including the frequency, the feature quantity, and the drive frequency.
