Alignment aid system for an ultrasonic transmitter, an ultrasonic detector assembly and an alignment method

A method for aligning an ultrasonic transmitter by means of an alignment aid system,

• the alignment aid system comprising:
• a receiver comprising a plurality of transducers each configured to receive a single ultrasonic wave transmitted by the ultrasonic transmitter and to convert the single ultrasonic wave into a respective signal, and a processing unit configured to process all signals coming from the plurality of transducers, at least part of the plurality of transducers being arranged so as to form a first continuous row of transducers, the receiver being distinct from the ultrasonic transmitter and being disposed at a position that is different than that of the ultrasonic transmitter;
• and
• an alignment control device arranged to communicate with the processing unit, the alignment control device being configured to supply an indication regarding transducers of the first continuous row of transducers receiving the single ultrasonic wave transmitted by the ultrasonic transmitter so as to enable the ultrasonic transmitter to be aligned in relation to the receiver;
• the method comprising:
• positioning the receiver at a location with respect to which the ultrasonic transmitter must be aligned;
• transmitting, by the ultrasonic transmitter, the single ultrasonic wave;
• receiving the single ultrasonic wave by the transducers of the first continuous row of transducers and converting into the signals;
• processing, by the processing unit, the signals coming from the transducers of the first continuous row of transducers;
• and
• supplying, by the alignment control device, an indication about a detection of the single ultrasonic wave transmitted by the ultrasonic transmitter along the first continuous row so as to enable the ultrasonic transmitter to be aligned in relation to the receiver.
