Abstract: An ultrasound transducer unit including a plurality of ultrasound transducers transmits and receives ultrasound waves to and from an inside of a subject. In a case where a checking operation unit is operated, a controller controls a driving voltage supply unit such that a driving voltage is supplied with all of the plurality of ultrasound transducers as driving target transducers. In a case where the checking operation unit is operated, a depolarization determination unit calculates, for each ultrasound transducer, a reception sensitivity in a case where an ultrasound wave is received by driving all of the plurality of ultrasound transducers as the driving target transducers, and determines whether or not a depolarization determination value calculated from the reception sensitivity of each ultrasound transducer satisfies numerical conditions. If the numerical conditions are satisfied, a polarization voltage supply unit supplies a polarization voltage to each of the plurality of ultrasound transducers.

Abstract: A vehicle approach warning apparatus for abnormality detection in various abnormal modes is provided. In the vehicle approach warning apparatus, a sound generator output from the microcomputer passes an AMP and HPF, and an output voltage corresponding to the sound generator output is applied to a speaker to emit vehicle approach sound. The vehicle approach warning apparatus includes a voltage sensor circuit and outputs a check usage output as the sound generator output at the abnormality detection. A single frequency output that is within a resonance frequency band of the speaker and that can be poorly reproduced by the speaker is used as the check usage output. The abnormality detection is performed based on whether an integration circuit voltage outputted from the voltage sensor circuit is within a voltage range being an abnormality determination threshold.

Abstract: An ultrasound probe includes a piezoelectric material, a signal electrode provided on the piezoelectric material, and a ground electrode provided on the piezoelectric material. Ultrasound waves are emitted from the piezoelectric material by applying a voltage between the signal electrode and the ground electrode. A switching element switches a connection between the signal electrode and the ground electrode from a closed state to an open state, and vice versa, in accordance with a control signal for controlling whether or not to emit the ultrasound waves. The switching element changes from the closed state to the open state in accordance with the control signal for emitting the ultrasound waves, and changes from the open state to the closed state in accordance with the control signal for suspending emission of the ultrasound waves. The ultrasound probe can maintain the reliability of the piezoelectric material when the temperature is high or changes suddenly.
