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:
A method and system for localization of fluorescence (120) in a scattering medium (104) such as a biological tissue are provided. In comparison to other optical imaging techniques, this disclosure provides for improved spatial resolution, decreased computational time for reconstructions, and allows anatomical and functional imaging simultaneously. The method including the steps of illuminating the scattering medium with an excitation light (102) to excite the fluorescence; modulating a portion of the emitted light from the fluorescence within the scattering medium using an ultrasonically induced variation (108) of material properties of the scattering medium (104) such as the refractive index; detecting the modulated optional signal at a surface of the scattering medium; and reconstructing a spatial distribution of the fluorescence in the scattering medium from the detected signal.
Abstract:
Holographic storage media (60) including a substrate and a dye material capable of undergoing a photo-induced change are disclosed. Data may be written into the holographic storage media using light of one wavelength and read using light of a different wavelength.
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.
