A co-operative project between HAAG Elektronische Messgeräte GmbH and Ultrasound Institute
Contract no.: 7603
To develop ultrasonic system for measurement of the position coordinates of the moving object.
Developed system consists of the small size transmitter of ultrasonic waves, fixed to the moving object, two receiving channels, separated by a specified distance 1m and the software for calculation and presentation of the 2 coordinates on PC screen. The transmitter is triggered wirelessly by infrared (IR) transmitter and is radiating 40kHz frequency ultrasonic pulses. These pulses are received by 2 receiving channels and processed by an embedded digital signal processor (DSP). In order to increase a noise robustness and accuracy of system, the transmitter radiates coded sequences, which are processed by the DSP.
Position of the ultrasonic source is determined by the binaural method.
