Claim 12:
13. The device of claim 1, wherein stimulating the plurality of transducers and receiving the reflected ultrasonic waves comprises:
stimulating the first transducer of the plurality of transducers to simultaneously transmit a first ultrasonic wave to the surface and to the deformable material;
receiving a first reflected ultrasonic wave from the surface at the first transducer in response to the first ultrasonic wave transmitted to the surface and a first reflected ultrasonic wave from the deformable material at the first transducer in response to the first ultrasonic wave transmitted to the deformable material;
stimulating a second transducer of the plurality of transducers to simultaneously transmit a second ultrasonic wave to the surface and to the deformable material;
receiving a second reflected ultrasonic wave from the surface at the second transducer in response to the second ultrasonic wave transmitted to the surface and a second reflected ultrasonic wave from the deformable material at the second transducer in response to the second ultrasonic wave transmitted to the deformable material;
stimulating a third transducer of the plurality of transducers to simultaneously transmit a third ultrasonic wave to the surface and to the deformable material;
receiving a third reflected ultrasonic wave from the surface at the third transducer in response to the third ultrasonic wave transmitted to the surface and a third reflected ultrasonic wave from the deformable material at the third transducer in response to the third ultrasonic wave transmitted to the deformable material; and
stimulating a fourth transducer of the plurality of transducers to simultaneously transmit a fourth ultrasonic wave to the surface and to the deformable material;
receiving a fourth reflected ultrasonic wave from the surface at the fourth transducer in response to the fourth ultrasonic wave transmitted to the surface and a fourth reflected ultrasonic wave from the deformable material at the fourth transducer in response to the fourth ultrasonic wave transmitted to the deformable material.
