Abstract: Compositions and methods of preparing functional thin films or surface coatings with low non-specific binding are described. The thin films contain specified functional groups and non-specific binding repellant components. The thin films are either covalently bound to or passively adsorbed to various solid substrates. The specified functional group provides specified activity for the thin film modified solid surfaces and non-specific binding repellant components significantly reduce the non-specific binding to the thin film modified solid surfaces. Non-specific binding repellant components do not affect specified functional group's activity in the thin films. In these methods, specified functional groups are anchored to the solid substrates through a spacer.

Abstract: The present method relates to the automated indexing of event images for distribution. The automated indexing can use automated facial recognition to determine which people are in each image. The images indexed in this fashion can be presented in a gallery, ordered by characteristics of the people in the images such as their name or room number, so as to facilitate the selection of the images by the people. The identification of the people in the images can be assisted by security or other information regarding the people that may be available to the event manager. Furthermore, the closeness of the relationships of two people can be inferred from the degree to which the people are in the same images, allowing the people in the images to be placed into groups, which can be hierarchical and/or overlapping, and which can assist in the organization of images being presented to the people, either in a gallery or electronic display format.

Abstract: A system authenticates an original hardcopy document using a digital signature generation system and a digital signature verification system. Initially, the original hardcopy document is scanned to provide a bitmap image to the signature generation system. The bitmap image is highly compressed by the signature generation system using compression schemes such as MPEG (for gray images) or a low-fidelity symbol based compression scheme (for bi-level images). A signed hardcopy document is then printed that includes the bitmap image and an authentication token. The authentication token is encoded in the signed hardcopy document using either serpentine halftone patterns or data glyphs. The authenticity of the signed hardcopy document is verified by inputting a scanned bitmap image of the signed hardcopy document into the signature verification system. Once received, the signature verification system decodes, authenticates, and decompresses the bitmap image to define decompressed image data.

Abstract: The invention relates to improving the efficiency of ion flow from an ion source, by reducing heat loss from the source both in the ion chamber of the ion source and its constituent parts (e.g. the electron source). This is achieved by lining the interior of the ion chamber and/or the exterior with heat reflective and/or heat insulating material and by formation of an indirectly heated cathode tube such that heat transfer along the tube and away from the ion chamber is restricted by the formation of slits in the tube. Efficiency of the ion source is further enhanced by impregnating and/or coating the front plate of the ion chamber with a material which comprises an element or compound thereof, the ions of which element are the same specie as those to be implanted into the substrate from the source thereof.

Abstract: The amount of moiré in halftone printed images is reduced using unique moiré intensity functions and moiré vectors in a halftoner. In various embodiments, moiré phase angle zones are determined over the full field of an image and high addressability units in the full-field moiré phase angle zones of the image are adjusted, including in an iterative manner, until they significantly reduce the moiré. A useful relationship between halftoner memory locations and moiré phase angle zones in a full field image is determined. The moiré that occurs in a halftone image is quantified and moiré compensation values obtained are then used to generate an inverse moire amount which is used to compensate for the moiré.

Abstract: A system is provided for processing data values in a data set to create a data value representation having a signal side. The data set contains valid data values and noise data values where the number of the valid data values is statistically insignificant with respect to the number of noise data values. The system determines a statistically significant portion of the signal side and fits a curve to the statistically significant portion which extends beyond the statistically significant portion of the signal side. Once the curve is determined, the system can determine a data-validity confidence value for one of the data values responsive to the curve. The data-validity confidence value can be used determine that a data value in a set of spectral data is not a noise data value.

Abstract: An XOR (exclusive or) encoded document is disclosed for establishing a joint secret between two parties. Encoded on the document are one or more areas of XOR messages. Each area containing an XOR message hides from view on each side of the XOR encoded document a different message on either side of a transparent base layer. To uncover a message in an area containing an XOR message on one side of the transparent base layer, the message on the other side of the XOR encoded document is scratched off and rendered illegible.

Abstract: Xerox Docket No. D/A0037Q Document authentication is accomplished by acquiring document image data, generating a set of features of the document, and generating an assist channel that includes information on how to generate the set of features. The set of features and the assist channel are digitally signed and then append to the document. Document verification is accomplished by acquiring document image data and verifying the signature. If the signature is valid, a set of features of the document is generated using information contained in the assist channel appended to the document. The generated set of features is then compared to the set of features appended on the document. If the sets do not match, the document is determined to have been altered sometimes after the assist channel was appended to the document, i.e., the document is not genuine. Otherwise, the document can be considered to be genuine.
