Abstract: Single X-ray grating differential phase contrast (DPC) X-ray imaging is provided by replacing the conventional X-ray source with a photo-emitter X-ray source array (PeXSA), and by replacing the conventional X-ray detector with a photonic-channeled X-ray detector array (PcXDA). These substitutions allow for the elimination of the G0 and G2 amplitude X-ray gratings used in conventional DPC X-ray imaging. Equivalent spatial patterns are formed optically in the PeXSA and the PcXDA. The result is DPC imaging that only has a single X-ray grating (i.e., the G1 X-ray phase grating).

Abstract: The embodiments provide for binding files to an external drive, a secured external drive, or portable data locker. The files are bound in order to help restrict or to prevent access and modification by certain computers or users. Computers or users that are authorized or within the authorized domain are permitted full access. The files stored on the external drive may be bound in various ways. The files may be encapsulated in a wrapper that restricts the use and access to these files. The bound files may require execution of a specific application, plug-in, or extension. A computer may thus be required to execute program code that limits the use of the secured files. In one embodiment, the external drive provides the required program code to the computer. In other embodiments, the required program code may be downloaded from a network or provided by an external authority.

Abstract: The embodiments provide for legally transferring multimedia content stored on a medium to a personal content archive device. The device is configured to consolidate a user's content into a single device or secured storage that allows easy access to the content while preserving the digital rights of the content. When a content medium has been provided, the device queries a registration service over a network, such as the Internet, to register the content and indicate that it was legitimately obtained. The device may then be authorized to download and store an authorized version of the content into its secured storage. The authorized version may be the same or a variation of the registered content. The content may then be downloaded from one or more content sources. The registration process may be based on several criteria, such as an authenticity check of the medium, a fee payment, and the like.
