METHOD AND SYSTEM FOR CALIBRATING ULTRASONIC SENSOR: abstract simplified (18185259)

• This abstract for appeared for patent application number 18185259 Titled 'METHOD AND SYSTEM FOR CALIBRATING ULTRASONIC SENSOR'

Simplified Explanation

This abstract describes a method for calibrating an ultrasonic sensor. The method involves transmitting an ultrasonic signal from the sensor towards a surface of a contact device. Ultrasonic images are generated by sampling the reflected signal of the ultrasonic signal at different reception time points. The method then detects portions of the ultrasonic images that are most similar to a reference image of a model placed on the contact device. The reception time points corresponding to these detected portions are stored for calibration purposes.

Original Abstract Submitted

A method for calibrating an ultrasonic sensor includes: transmitting a first ultrasonic signal from the ultrasonic sensor toward a first surface of a contact device when a model is on the first surface of the contact device; generating ultrasonic images by sampling a first ultrasonic echo signal, the first ultrasonic echo signal comprising a reflected signal of the first ultrasonic signal, at a plurality of reception time points; detecting portions of the ultrasonic images, wherein detected portions of the ultrasonic images are most similar to corresponding portions of a reference image of the model compared to other portions of the ultrasonic images having same positions as the detected portions and detected at different reception time points of the plurality of reception time points than the detected portions; and storing the reception time points corresponding to the detected portions of the ultrasonic images.
