the method includes comparing the measured echo value at each sensing position to a reference echo value corresponding to the same sensing position and to iteratively determine a new reference value whenever the echo value is greater than the reference echo value and that the difference between the measured echo value and the reference echo value is lower than a detection assurance factor the use of the adaptive ultrasound sensing system and method allows locating the sensor at different location without requiring a new calibration thereof since the sensor learns the clutter dynamically and the detection thresholds are being built accordingly without being dependent on the environment in which the sensor is located application_number US 42077306 A description turning now to fig1 of the appended drawings an adaptive ultrasound detecting system 10 according to an illustrative embodiment of the present invention will be described the detecting system 10 comprises a controller 12 a pulse generator 14 coupled to the controller 12 a sensor driver 16 coupled to the pulse generator 14 a transducer 18 coupled to the driver 16 an analog circuit 20 coupled to both the transducer 18 and to the controller 12 a memory means in the from of an eeprom electrically erasable programmable read only memory 22 coupled to the controller 12 input output i o means 24 and an i o interface coupled to the i o means 24 the controller 12 pulse generator 14 sensor driver 16 transducer 18 and analog circuit 20 are connected to a power supply 28 in the form of a 12 24 dc direct current voltage source of course the power supply 28 may take other forms allowing energizing the system 10 the pulse generator 14 includes an oscillating circuit and allows generating a.
