Application: Ultrasonic generator, transducer, and object detector (Patent ID: US20230336921A1)
The patent filed by Aisin Corp. describes an ultrasonic generator with a transducer that includes a piezoelectric body and three or more electrodes for generating ultrasonic waves based on the directivity information received by a control unit. The control unit selects the appropriate combination of electrodes to apply the alternating voltage and generate the ultrasonic waves, allowing for control over the directivity of the waves produced. Additionally, the generator may store correspondence information between electrode combinations and directivities for more efficient wave generation.
Furthermore, the patent extends to an object detector utilizing the ultrasonic waves generated by the transducer. The detector includes a transmission unit that changes the electrode combination for generating waves and a reception unit that receives and processes reflected waves. By controlling the frequency, phase, and amplitude of the ultrasonic waves, the detector can differentiate between waves with different directivities, allowing for accurate identification of the original waves from the reflected ones. This system enables the detector to effectively transmit and receive ultrasonic waves for object detection purposes.
