摘要:
An image is processed to encode a digital watermark, with different regions thereof processed using different levels of watermark intensity. In an image comprised of elements of differing sizes (e.g., halftone shapes of different sizes, or lines of different width), the different regions can be defined by reference to the sizes of elements contained therein. Regions characterized by relatively small elements can be watermarked at a relatively low intensity. Regions characterized by relatively large elements can be watermarked at a relatively high intensity. A variety of other features are also discussed.

Colored images are divided into color planes and watermarks are inserted into the individual color planes. One or more watermarks can be inserted into one or more of the color planes. In order to print a color image the image is divided into color planes corresponding to the colors of ink used for printing. A separate plate is used to print each color. The different plates must be precisely aligned. Any misalignment will cause blurring in the image and may make it difficult or impossible to read a watermark in the image. Misalignment of the plates can cause the watermark data in one color plane to, in effect, cancel out the watermark data in a different color plane. With the present invention a watermark is inserted into a selected color plane only, thus there is no cancellation due to misalignment of color plates. The watermark detection and reading can be done after the image is divided into color planes.

Systems and methods are provided for storing and retrieving thumbnail images in a per-user/per-system thumbnail cache. One or more data files may be used to store thumbnail images of varying sizes. An index is updated with the location or locations of thumbnails for a particular file, the URL and modification time of which may be used as a key to finding the thumbnails within the index. Direct memory mapping of thumbnail images are provided. Concurrency techniques are utilized to maintain cooperative access to the cache among multiple processes. Cache contents which are orphaned or unused are reclaimed for use by newer or more frequently used thumbnail images.

The present invention provides methods and systems to manage the exchange of medical information between two or more entities. Particularly, the present invention provides for computer-implemented systems and methods that are useful for transferring diagnostic medical examinations between hospitals, diagnostic imaging centers, medical clinics, physicians, physician groups, or entities employing physicians. The present invention further provides a method in which prospective consumers (e.g., hospitals, diagnostic imaging centers, and medical clinics) may engage the medical interpretation services of geographically dispersed providers (e.g., physicians, physician groups, or entities employing physicians).
摘要:
A character programming method (10) whereby a synchronization character (17) can be determined in a determine encoding scheme operation (12) and a determine synchronization character operation (14). The synchronization character (17) can then be programmed into a synch character logic (26) of an integrated circuit (20) or a core (20) thereof. The synch character logic (26) can be programmed through a plurality of program pins (30) on the periphery of the integrated circuit (20) or by more sophisticated means such as by sending the programming from a sending integrated circuit (40) to a receiving integrated circuit (42) through a communications line (44).
摘要:
Some embodiments provide an integrated circuit (“IC”) with a primary circuit structure. The primary circuit structure is for performing multiple operations that implement a user design. The primary circuit structure includes multiple circuits. The IC also includes a secondary monitoring structure for monitoring multiple operations. The secondary monitoring structure includes a network communicatively coupled to multiple circuits of the primary circuit structure. The secondary monitoring circuit structure is for analyzing the monitored operations and reporting on the analysis to a circuit outside of the IC.
摘要:
Certain aspects of a generic user interface command architecture allow an application to host commands for presentation on a computing device. The commands can be written by the same designer or author as the application, or alternatively by other parties (e.g., by a third-party developer). Other aspects of the generic UI command architecture describe an application programming interface (API) that can be used to allow the application to host the commands. Other aspects of the generic UI command architecture describe an activation mechanism by which registered commands can be activated by an application.
摘要:
Digital watermarks can be employed in conjunction with trading cards (e.g., baseball cards, fantasy game cards, etc.) to serve a variety of purposes. Among these are facilitating on-line collecting and game-play. Digital watermarks may also be used in distinguishing genuine cards from counterfeits.
