| 20080300811 | Method For Compensating For A Contaminated Calibration Target Used In Calibrating A Scanner - A method for compensating for a contaminated calibration target used in calibrating a scanner having a plurality of sensor pixels includes (a) scanning a calibration target to generate a respective plurality of calibration data samples for each sensor pixel of the plurality of sensor pixels; (b) for calibration data samples associated with a current sensor pixel of the plurality of sensor pixels, removing any calibration data sample that corresponds to a region of calibration target contamination, leaving filtered calibration data samples; (c) determining a gain value for the current sensor pixel based on the filtered calibration data samples; (d) repeating acts (b) and (c) for a next sensor pixel until a respective gain value is determined for each of the plurality of sensor pixels; and (e) applying the determined gain values to the plurality of sensor pixels for use in subsequent image scanning by the scanner. | 12-04-2008 |
| 20090103142 | Method and apparatus for reducing aliasing artifacts in scans of screen printed originals - Method and apparatus of reducing aliasing when scanning a screen printed document including removing high frequency image information at the input of an image sensor prior to scanning. Removing high frequency image information increases the effective sampling frequency of the scanner thereby reducing the effects of aliasing by. Removal of high frequency image information is achieved by adjusting the focal position of the image sensor from a focused position to a defocused position using a mechanism for moving the image sensor or scan bar relative to either the scan bed or a document to be scanned. | 04-23-2009 |

| 20100071056 | METHOD AND SYSTEM FOR MULTI-PROTOCOL SINGLE LOGOUT - A method for multi-protocol logout. The method includes receiving, by a first identity provider, a logout request from a user agent, wherein the first identity provider executes in a federation manager, and initiating a logout on a service provider associated with the first identity provider based on the logout request by the first identity provider. The method further includes identifying, by the federation manager, a plurality of identity providers associated with the user agent, wherein the plurality of identity providers communicate using heterogeneous federation protocols, and initiating, by the federation manager, a logout on each of the plurality of identity providers based on the logout request using the plurality of heterogeneous federation protocols. The method further includes initiating, by the plurality of identity providers, a logout of each service provider corresponding to the plurality of identity providers, identifying a status of each logout, and sending the status to the user agent. | 03-18-2010 |
