Abstract
An apparatus according to an embodiment includes an array of transducers including an inner transducer and subarrays of the transducers positioned on opposite sides of the inner transducer, and a controller coupled to the transducers. The controller is configured to process data using only the transducers in the subarrays in a first mode of operation. Moreover, the controller is configured to process data using only a portion of the transducers in each of the subarrays in a second mode of operation, where the inner transducer is inactive in the second mode of operation.
