摘要:
Methods for mapping color data having at least one color associated therewith to an output device based on an input device profile and an output device profile, each profile having a tone curve and a color matrix, are provided. In one embodiment, the method includes receiving color data from an input device and determining whether the color data is in a linear space. If it is determined that the color data is not in a linear space, the method further includes applying the tone curve of the input device profile to the color data to convert it into a linear space. The method further includes converting the color(s) associated with the color data from the input linear space to an output linear space by applying the color matrix of the input device profile and the inverse color matrix of the output device profile to create color-converted image data.

A method and system for controlling gamut mapping algorithm parameters and exposing those parameters as user interface elements to allow users to interactively control the gamut mapping algorithm parameters is provided. A request to modify a user interface is received and a modified gamut mapping algorithm parameter element is loaded into the user interface in response. The request to modify can be a request to modify a pre-existing gamut mapping algorithm parameter element or a format of a corresponding gamut mapping algorithm parameter. User specified requests to adjust gamut mapping algorithm parameter elements are received and color management operations are adjusted in response. A three dimensional representation of a device color gamut can be displayed and modified by a user, and an input image that is being processed by the color management operations is displayed and modified dynamically in response to user specific adjustments.

Methods and apparatuses for supporting a color management system that processes an image in accordance to a hierarchically-structured policy are provided. The policy may be modeled with a schema in which the policy is organized with a plurality of policy levels. Policy settings at a lower policy level may override policy settings at a higher policy level, which may be inhibited with a lockout mechanism. A user interface supports the capability of a user configuring policy settings through a series of dialog boxes. The dialog boxes are hierarchically organized in accordance with configuration levels, where the configuration levels are associated with the policy levels. The dialog boxes provide a consolidated approach for configuring a color management system by a user. An interface is supported, enabling a component to send inputs to a color management system in order to configure the policy.

An operating system (OS) includes a color adjuster that can map a color space to an adjusted color space that a user can discriminate. The color adjuster can map colors in the gaps of the user's discriminable color space to colors that the user can discriminate or, alternatively to cues. The OS can also include an assessor to determine whether a user would benefit from the use of an adjusted color space. The assessor can also receive color discrimination data associated with a user without having to perform an assessment (e.g., from a profile or “passport” that includes data from a previous assessment performed on another computer or device). This data can be stored on removable media, a smart device, a node on a network, and then accessed by the assessor.
摘要:
A surgical stapler is provided having a cartridge arm for holding staples, an anvil pivotally connected thereto to deform fired staples from the cartridge arm, and a support for substantially preventing anvil deflection during staple firing to help insure proper staple formation. Some supports allow pivoting between the anvil and cartridge arm when in a first position, but prevent or hinder the pivoting action when in a second position. Supports can also be adapted to contact the anvil at a distal position relative to the pivot point between the anvil and cartridge arm. Exemplary structures of supports embodied as one or more links or as a sleeve are described. Methods of use are also discussed.

A system and related techniques detect and manage the set of rights associated with a componentized electronic document, including to separately protect and manage individual text, graphic, audio, video or other parts of a multimedia presentation. Unlike prior digital asset management platforms which could enforce encryption or other protection simply around the entire object, the invention permits individualized control over separate media components, to permit distribution for example of some parts, such as text passages, while preventing unauthorized access or copying of audio, photographic, video or other files or content. The electronic document may maintain a list of media components and the set of rights associated with each such component, and a content server or other source may apply key encryption or other safeguards to guide the delivery of the overall media object or its parts, for instance to view in a browser, print on a printer or otherwise access, manipulate or output the content.
摘要:
Methods and devices for illuminating a body cavity or an internal region of a body are disclosed. In one aspect, a percutaneous illumination device for illuminating a body cavity includes an elongate member with an illumination source, and two support members disposed on the elongate member that are adapted to be positioned on opposite sides of a tissue surface for stabilizing the device. Variations on such an illumination device, kits that include such devices, and methods of utilizing such devices are all described within the present application.
摘要:
A cooling arrangement for an electron collector of an electron beam tube has a plurality of solid dielectric spacers surrounding the corrector with an electrically insulative and thermally conductive dielectric liquid in gaps between the spacers. A water cooling system is arranged in thermal contact with the spacers and the liquid dielectric to provide cooling by water circulation. The cooling arrangement is a hybrid of oil and water cooling systems in which the electrically non conductive oil is arranged in gaps between dielectric spacers, the dielectric spacers provide a support for the surrounding water coolant system and ordinary water may be used to be pumped through the water cooling system.
