Abstract: Watermark encoders and decoders can be integrated into operating systems, Internet browsers, media players, and other applications and devices. Such integration enables the watermark-enabled application or device to provide additional functionality and information available via the watermark. The watermark, for example, may link to metadata or actions related to a media object. To exploit this watermark enabled functionality, the integrated application uses a watermark decoder to access the related metadata and actions. The user interface of the integrated application is enhanced to present metadata and actions linked via the watermark. Similarly, watermark encoders may be integrated into applications to convert media objects into enhanced, watermarked objects. A variety of other arrangements and features are also detailed. Many arrangements can be implemented using object identifiers other than watermarks.

Abstract: The present invention relates to systems and methods for the determination of the secondary structure composition of proteins using coherent two-dimensional infrared (2DIR) spectroscopy of backbone amide I vibrations (1580-1720 cm?1). Fractions of ?-helix, ?-sheet, and unassigned regions in globular proteins were determined by singular value decomposition using basis spectra from sixteen commercially-available proteins with known crystal structures. Preferred methods included removing each protein from the set and comparing the predicted composition against the crystal structure. The root-mean-squared (RMS) errors of the predicted secondary structure compositions were found to be 7.9% for ?-helix, 5.5% for ?-sheet, and 7.6% for unassigned regions. The structure analysis can also be performed using one-dimensional absorption spectra and the RMS errors are compared with those obtained from 2DIR.

Abstract: Disclosed is a fluid sampling device comprising a plurality of inlet channels, each of which is arranged to receive an airflow from an associated direction, such that a sampling medium associated with a particular inlet channel is exposed to airflow from the associated direction.

Abstract: An electronic system where messages include information carried by digital watermarks. The digital watermarks are used to control the transmission and/or receipt of messages including images or audio transmitted over the system. The system prevents the accidental dissemination of information to unauthorized receivers. Furthermore, while no security system is fool-proof, the system helps guards against the intentional, but unauthorized, dissemination of information to unauthorized receivers.

Abstract: Various improvements relating to digital watermarking and related technologies are detailed, including methods that enhance security and functionality, and new articles including watermarked puzzles and marked DNA.

Abstract: An electronic e-mail system where messages contain information carried by digital watermarks. The digital watermarks are used to control the transmission and/or receipt of documents transmitted over system. The invention can be used to prevent the accidental dissemination of information to unauthorized receivers. Furthermore, while no security system is fool-proof, the present invention helps guards against the intentional, but unauthorized, dissemination of confidential information to unauthorized receivers.

Abstract: A method of performing digital asset management of media content. In this method, a watermark reader device reads a watermark embedded into media content. The watermark conveys watermark information, such as a content identifier and creator identifier. The reader forwards the watermark information to a router. The router then uses the watermark information to find a metadata database identifier. It then sends a request for metadata along with the watermark information to the metadata database identified by the metadata database identifier. The metadata database uses the watermark information to find related metadata for the media content and sends the related metadata to the reader device.

Abstract: An improved hat holder having a crown ring and at least one adjustable strap for receiving a hat of the type having a crown and a brim for securing the hat to a surface. In a preferred embodiment, a pair of straps are connected to the surface by means of a first pair of Velcro pads connected to the ends of the straps and a second pair of Velcro pads adhesively connected to the surface whereby the hat may be conveniently placed or removed from the holder by simply separating one or both such straps at the Velcro pads from the surface.
