Bayesian Network Expert System: U.S. Patent No. 6,076,083 “Diagnostic System Utilizing a Bayesian Network Model Having Link Weights Updated Experimentally”

This patent covers a method for reducing the amount of data needed to automatically update the probability matrices of the network on the basis of experiential knowledge, and methods and algorithms for automatically collecting knowledge from experience and automatically updating the Bayesian network with the collected knowledge. A practical exemplary embodiment provides a trouble ticket fault management system for a communications network.

It is an improvement upon traditional computer expert/diagnostic systems in that it employs Bayesian probability in its calculations and adaptively updates its probability model as it receives new incoming information (or "evidence"). The exemplary embodiment is particularly appropriate for utilizing the automatic learning capabilities of the invention. In the exemplary embodiment, a communications network is represented as a Bayesian network where devices and communication links are represented as nodes in the Bayesian network.

Knowledge Driven Software Architecture: U.S. Patent Nos. 7,774,751 and 7,966,093

This portfolio is a potentially valuable asset for software development companies that require changing scenarios to be directly included in a software application, and for the companies involved in development of intelligent multi-robot systems having adaptive behavior models. The system learns the changing scenarios on the basis of inputs supplied by a subject matter expert. Further, the technology describes a system that allows an expert to provide the input in ontology language (which is closer to natural language) and translates the input to figure out a user’s intent. The system can learn new rules at run time to match the expert’s expectation.

Secure Passwords Utilizing Spatial and Chromatic Patterns: U.S. Patent No. 7,844,825 “Method of generating a spatial and chromatic password”

This patent covers a method of generating a non-linear spatial and chromatic password that results in a password that offers a high level of security and anti-decryption characteristics.

The technology includes the steps of establishing a spatial password entry pattern (SPEP) within boundary conditions of a matrix of a password entry screen (PES), with the SPEP including coordinates of the matrix of the PPS. The method also includes selecting a first color from a color selection keypad (CSK) having many selectable colors. The first color is then mapped to a first coordinate of the SPEP of the matrix. Then, a second color from said CSK is mapped to a second coordinate of said SPEP. The above steps of selection and mapping are then repeated for N coordinates, each corresponding to a selected color of the CSK, until all coordinates falling within the boundary conditions defining said non-linear SPEP are fully mapped.

Cellular Network Equalizers: 11-Patent Portfolio Covering Various Aspects of Cellular Network Equalizers

In existing and future cellular wireless networks, the increasing demand for data services is causing the network’s performance to depend on transmitter radio-output power. This requires large increases in radio transmit power, further highlighting the need for better and higher output-power transmitter radio amplifier technology. One solution will result in a significant increase in the cost and power consumption of the cellular telephone and the network base station. An alternative is to use the technology covered by this portfolio that allows use of lower cost and power-consumption transmitter radio amplifiers.
 
One of the significant drawbacks of 3G and 4G technologies is experiencing large peaks or peak-to-average-power-ratio (PAPR) in the transmit radio signal. This characteristic of the 3G and 4G technologies requires transmitter radio components including the power amplifier with very high linearity and therefore, higher cost and power consumption.

The technologies in this portfolio are extremely simple techniques for Peak-To-Average-Power-Reduction (PAPR) and Digital Pre-Distortions (DPD) of the transmitter radio signal to reduce the need for highly linear transmitter radio components. This eventually results in lower cost and power consumption of cellular phones, consumer premises equipments (CPEs) and network base stations.

Deep Web Crawling: U.S. Patent Nos. 7,756,807 and 7,454,430 “System and Method for Facts Extraction and Domain Knowledge Repository”

This portfolio covers technology related to a system for facts extraction of application-specific data such as business information from various semi-structured and unstructured online sources (documents/web pages) such as newspapers, company web pages, blogs and other social media.
 
The system extracts the facts and analyzes it using knowledge agents. Further, information gathered from various sources is compared to remove any false positives and duplicates. Finally, the facts are stored in a domain knowledge repository to serve different search applications. The system vastly expands the number of web pages from which fact can be extracted by automatically navigating the Deep Web and extracting web pages that are not visible to the existing search engines due to lack of a URL and, therefore, are inaccessibility using existing URL link-based crawlers.
