Patent CA-2407889-A1 (CA)
Inventor: PIDGEON CHARLES
IPC: G01N33/53
Filed: 2001-05-02
Abstract: A drug-binding substrate formed or identified using a drug substance having a predetermined biological activity is used to screen and identify test compounds likely to exhibit the predetermined biological activity. The potential biologically active test compounds are identified by their specific binding to the drug-binding substrates as detected by any of a wide variety of techniques using labeled or unlabeled assay components. In one embodiment a monoclonal antibody raised against a drug substance is used as a drug-binding substrate to identify and isolate test compounds in a natural product extract or a combinatorial chemical library. Preferably the monoclonal antibody is characterized by its ability to bind specifically to at least one other drug substance having the same or similar biological activity as the drug substance against which it was raised. The invention finds use inter alia in drug discovery protocols, in toxicity profiling of drug substances and in assaying commercial natural products.

Title: User profile classification by web usage analysis
Inventor: ADAR EYTAN
IPC: G06F17/30
Filed: 2002-10-25
Abstract: Demographic information of an Internet user is predicted based on an analysis of accessed web pages. Web pages accessed by the Internet user are detected and mapped to a user path vector which is converted to a normalized weighted user path vector. A centroid vector identifies web page access patterns of users with a shared user profile attribute. The user profile attribute is assigned to the Internet user based on a comparison of the vectors. Bias values are also assigned to a set of web pages and a user profile attribute can be predicted for an Internet user based on the bias values of web pages accessed by the user. User attributes can also be predicted based on the results of an expectation maximization process. Demographic information can be predicted based on the combined results of a vector comparison, bias determination, or expectation maximization process.

Filed: 2001-05-22
Abstract: A system and method for authenticating documents and content thereof. A  counterfeit resistant document recording medium is provided, having thereon a predefined unique document identifier (Figure 2) and at least one security feature (Figure 2). The recording medium is thereafter imprinted with document content (Figure 2), which typically varies between documents. The document content is stored in a database, indexed by an associated document identifier.  The document may then be authenticated by checking the security feature and comparing the stored document content with a perceived document content. The system provides a number of opportunities for commercial exploitation, including sales of identified recording media, recording of information in a database, on-line authentication transactions, differential accounting for document validations and counterfeit identifications, imprinting devices, authentication devices, and the like. The system prevents counterfeiting of valuable documents through casual means by providing both physical and logical security.

Title: International automatic line height, font size and font measurement system and method
Inventor: BROWN DAVID C
IPC: G06F17/21
Filed: 2003-03-10
Abstract: A system and method automatically determines appropriate font characteristics for different display mediums and different readability parameters in any language. A method includes determining font characteristics by receiving data including a font identifier and a language identifier, producing a representative line of type in the identified language and with the identified font, measuring characteristics of the representative line of type, and normalizing the measurements across a plurality of fonts and a plurality of languages. The normalizing refers to widths of portions of the text called a "black river", which is used to identify plotted measured characteristics to determine an average grayness across a perpendicular to a reading direction. The average grayness enables comparisons to pluralities of fonts and languages. A system and method determines an optimum size for a font for readability. A method determines font characteristics by determining a character density for the font and multiplying the character density by a sharpest focusable area of the viewing medium.
