    Abstract: A storage medium (800) capable of being read by player (900), the storage medium comprising: digital content disposed along one or more tracks (104) of the storage medium; and an authentication program (808) disposed along the one or more tracks of the storage medium for authenticating (1000, 1100) the storage medium by determining whether the one or more vague bits (330, 332, 424, 426, 428, 524, 526, 528, 624, 626, 628, 724, 726, 728) exist at the one or more predetermined locations (810). There are also provided a method for authenticating (1000, 1100) a storage medium and a method for crating (1200, 1300, 1400) a storage medium having the one or more vague bits.

    Abstract: The present invention discloses an acoustic composite material (28) for an ultrasonic phased array and a method for making. The acoustic composite material (28) is formed from a microcapillary array (30) having a plurality of holes (32) of a constant cross-section and volume fraction. In each of the plurality of holes (32) of the microcapillary array (30), a polymer fill (34) is deposited therein. The polymer filled microcapillary array (30) is cut at an axis perpendicular to the microcapillary array into a plurality of sections (36). Each of the plurality of sections (36) are then ground into a predetermined thickness and bonded to a phased array of piezoelectric elements and backfill material.
