Abstract: A medical device system that includes an ultrasound transducer and a processor. The ultrasound transducer includes a plurality of electrode plates to which a drive signal is supplied, and a plurality of piezoelectric elements that are alternately arranged with the electrode plates, and that generate ultrasound vibrations according to the drive signal. The ultrasound transducer also includes an electric wiring that electrically connects the electrode plates adjacent to each other, and a memory that stores reference information regarding specific initial characteristics.

Abstract: A fuel cell system includes: a fuel cell that generates power by being supplied with a reaction gas; an air pressure regulator that regulates an air pressure, which is a pressure of an oxidant gas passing through the fuel cell; and a control device that controls a power generation amount of the fuel cell.

Alternatively, when the air pressure is lower than a predetermined low-pressure reference value while the required output to the fuel cell shows an increasing tendency, the control device limits or delays an increase in the power generation amount of the fuel cell.
