Systems and methods for processing content packages such as human-readable documents identify and analyze content type. Structural and logical evaluation of a Content package is performed, followed by analysis and indexing of concepts within the package. Analysis and identification of concepts and sub-concepts may be an iterative process. Concepts are indexed in accordance with different rule sets representing Different consumer needs and perspectives. Customers can then use the indices to navigate large groups of content packages based on the concepts contained within those packages and also on keywords associated with concepts.

Disclosed herein are systems and related methods for reducing speckle on display screen. More specifically, screen vibration is used to reduce speckle, and in accordance with the disclosed principles, the vibration may be achieved by using wave-based actuation (e.g., acoustic or electromagnetic waves) to vibrate the screen. In an exemplary embodiment, a speckle reducing system may comprise at least one actuating element located proximate to, but not in physical contact with, a display screen. In addition, the at least one actuating element may be configured to generate waves directed towards the display screen. When the waves impact the display screen, the waves impart vibration to the display screen.

Disclosed is an article having a holographic recording medium having digital data that cannot be seen by human eye, wherein the holographic recording medium is a holographic material that records volume holograms that permit authentication of the article and the holographic material is attached to or part of the article. Also disclosed is a method of authentication of the article.
摘要:
According to one aspect, methods and systems for recording and reading holographic storage media are provided. In one aspect, a method includes illuminating a data mask with a beam and recording a resulting modulated beam in a holographic storage medium, wherein the data mask includes an information layer that is divided into multiple data pages, and propagating a reference beam to the holographic storage medium to record the multiple data pages of the data mask in a parallel fashion on the holographic storage medium.

摘要:
Associative retrieval techniques of this invention allow a holographic recording device to simultaneously query a plurality of storage locations for the presence of a given data pattern. The techniques use a known pattern common to one or more storage locations to simultaneously verify the success of one or more write operations.
