Ultrasonic transceiver with the possibilities of the data communication and the two-point distance measurement

This paper deals with the problem of the short distance measurement between two (or more) moving points with the ability of a simple data communication. Different possibilities were explored and using the ultrasonic transceiver was then chosen for a future development. The article describes a solution which uses ultrasonic transceivers and allows the distance measurement between two moving points (model master-slave) up to 5 m with the simultaneous communication (bit rate 100 bit/s). The paper also proposes a possible future development to extend the model to more than 2 points distance measurement and communication
