The adaptive system and method for ultrasound sensing comprises re-evaluating over time the detection threshold for predetermined sensing positions along the scanning direction to cope for the static target and environment changes at the sensing positions. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. In this method, an synthesized interference signal is generated based on the first digital signal. The controller is adapted to coordinate the plurality of transponders for imaging the pressure variations on the surface. When the electronic merchandise is ready, the service provider may advertise the merchandise using a method specified by the reseller.
