Abstract: A client-based method for implementing a communications link. The method includes receiving a request for a communications link from an application executing on a handheld device and accessing a device API component to configure device hardware to implement the communications link. A wireless communications link is established with a server. In optimized protocol is automatically implemented between a client communications component and the server based on the wireless communications link type and the handheld device type, wherein the communications link is established via the communications component functioning with a device API component to configure hardware of the handheld device.

Abstract: A server-based method for implementing a communications link. The method includes receiving via a communications network a request for a communications link from a client communications component executing on a handheld device and establishing a wireless communications link with the handheld device by using a server communications interface executing on the server. An optimized protocol is automatically implemented between the client communications component and the server based on the wireless communications link type and the handheld device type, wherein the optimized protocol is implemented while maintaining a standardized application programming interface for the server communications interface, and wherein the communications link is established via the communications component functioning with a device API component to configure hardware of the handheld device.

Abstract: A system for displaying products for purchase on any document displayed on any computer device, comprising conducting a statistical frequency analysis of the word occurrence in the document to determine the primary subject matter of the document and/or keywords in the document, selecting products which are relevant to the subject matter and keywords of the document, either by manual selection or by automatic selection. Automatic selection is accomplished by conducting a statistical frequency analysis of the word occurrence in the product descriptions to determine the keywords in the product descriptions and matching the keywords from the document with the keywords from the product descriptions.

Abstract: Methods for performing secure on-line testing without the need for pre-installation of a secure browser are provided. The methods use a general purpose web browser which is already installed on the user's computer and extend the browser so as to restrict the functionality of the user's computer in at least one way which makes the computer more secure with regard to testing. The extending occurs through the transmission of trusted code to the user's computer over the internet. The elimination of the need for pre-installation represents a major savings to school districts in terms of the amount of IT professional time that must be dedicated to on-line testing, especially for school districts having large numbers of installed computers. Apparatus for practicing the methods is also provided.

Abstract: A system for displaying products or services for purchase on any document displayed on any computer device, comprising conducting a statistical frequency analysis of the word occurrence in the document to determine the primary subject matter of the document and/or keywords in the document, selecting products which are relevant to the subject matter and keywords of the document, either by manual selection or by automatic selection. Conducting a statistical frequency analysis of the word occurrence in the product or service descriptions, to determine the keywords in the product descriptions, and matching the keywords from the document with the keywords from the product descriptions accomplish automatic selection.

Abstract: A system for conducting queries from any document displayed on any computer device, comprising the creation of more focused “brilliant queries” by conducting a statistical frequency analysis of the word occurrence in the document to determine both the primary subject matter (the hook) of the corpus and the keywords in the corpus, using editorial judgment or filtering of the keyword list to determine the most important keywords, application and tuning of the keyword set to target particular databases and adding the suggested hook/keyword combinations to the document for use by the computer user in selecting queries.

Abstract: A system and method for optimizing medical diagnosis, procedures and reimbursement claims using a structured search space is described. The system may comprise: a master procedure list of alphanumeric codes that represent each of a plurality of medical procedures, wherein the master procedure list includes simple procedures and compound procedures which consist of at least two simple procedures; a value associated with each of the plurality of medical procedures; a list of ordered procedures listing medical procedures for a specific medical encounter; a search tree of all possible combinations of the simple procedures and the compound procedures in the list of ordered procedures; and a minimum total of the values associated with the medical procedures in the list of ordered procedures.
