Abstract: Disclosed is a system and method for managing mailing list newsletter messages for a recipient user, and organizing such messages in accordance with a receiving user's interests. The present disclosure enables novel organizational tools for emails by intuitively organizing received newsletters and providing highly visible features within a user's inbox respective the newsletters. Organization of received newsletters is ensured through ranking users' mailing lists according to his/her interest in them, based on actions made by the respective user, in addition to actions of other users receiving the same newsletters. Additionally, upon reception of such newsletters, the present disclosure provides a specialized view, in addition to added functionality within a user's inbox, thereby enhancing a user's experience and engagement with received messages of a newsletter.

Abstract: A query is received to search data, where the query includes a search term. A search of the data is performed in response to the query, wherein the search produces result data based on the search term and an identifier of a searcher submitting the query.

Abstract: Disclosed herein is an enhanced device personalization that personalizes a user's experience with a device, e.g., a multi-user device. Rather than personalizing based on the specific user(s) that are using, an active entity, which represents a type of consumption, may be generated and used to make recommendations for personalizing an experience using the device. In a case of a multi-user device, each user's experience is personalized by determining an active entity for the user's experience and without knowledge of which user is using the device.

Abstract: Disclosed is a system and method for selectively delivering shared information. The disclosed systems and methods enable a sending user to decide what context of information is to be shared, in that a sending user can determine when and where information is shared. This enables increased social engagement towards relevant information. Additionally, this enables a vast opportunity for commercial opportunities, whereby advertisements can be served contingent upon a consumer's context, and/or only when the product or service offered to the consumer is relevant.

Abstract: Techniques for correcting the color uniformity of a laser printer of a digital press or other device are provided. A process for correcting the color uniformity of a laser printer may include scanning a test page by an inline scanner of a digital press, determining scanner signal data from the test page, determining a scanner polynomial fitted to the scanner signal data, and determining a non-uniform coverage polynomial from the scanner polynomial. Additionally, techniques for verifying the linearity of a scanner are also provided.

Abstract: A method comprises computing an activity map for an input image. The activity map indicates an amount of variable spatial activity in the input image. The method further comprises producing an output image based on the activity map, and controlling a printhead to cause the output image to be printed. The output image contains a plurality of color pixels and each such color pixel is represented by at least one of cyan (C), magenta (M), yellow (Y), and black (K) in a color space.

Abstract: A method of accurately printing a target color is provided. The method comprises: in a first step measuring the light spectrum (106) of a first printed color sample (104), which has been printed with a first ink coverage; and from the measured light spectrum calculating a color discrepancy between the first printed color sample and the target color. The method further comprises in a second step calculating an improved ink coverage (112), and printing a second color sample with the improved ink coverage (104). The aforementioned steps are repeated until a predetermined condition for accuracy of the target color has been reached (110).

Abstract: A component of a color printing system, such as lookup tables for converting requested marking-agent coverages to corresponding half-tone screen sizes, is calibrated. The calibration can be effected off an arbitrary image and involves making reflectance spectrum measures of the printed image at multiple locations. Expected reflectance measures for each measurement location are computed based on the requested coverage value for each of the marking agents printed there. The computed measures may be dependent on a parameter. A value of the parameter is determined that minimizes the aggregate differences between the sensed and expected reflectance-spectrum measures, and this value is then used in calibrating the component.

Abstract: Measurement data relating to an image of a sample acquired by a measurement device is received (202). A problem is solved that seeks a solution for a spectrum (204) of the sample, based on a non-linear model for estimating a spectral response and on a profile of the measurement device.

Abstract: Event analysis methods and apparatus in which sequences (44, 46) of one or more events are identified based on event records (20) describing the events. Respective distance values (28) representing distances between ones of the sequences (44, 46) are determined. A configuration of points in a target metric space is constructed based on the distance values (28), where each of the points represents a respective one of the sequences (44, 46). A visual representation (38) of the configuration is presented on a display (34).

Abstract: A signal processing system adapted for sparse representation of signals is provided, comprising: (i) one or more training signals; (ii) a dictionary containing signal-atoms; (iii) a representation of each training signal using a linear combination of said dictionary's signal-atoms; (iv) means for updating the representation of the training signal; (v) means for updating the dictionary one group of atoms at a time, wherein each atom update may include all representations referring to said updated atom; and (vi) means for iterating (iv) and (v) until a stopping rule is fulfilled. The system uses the K-SVD algorithm for designing dictionaries for sparse representation of signals.
