Abstract: A search engine finds patents, patent applications and related documents and presents a selection of found documents in textual formats and/or graphical formats. After executing a search, the displayed information may include a selection of results sorted by inventor name, year and other variables found within patent documents. Financial data pertaining to patent owning entities is presented along with patent portfolio analysis and estimates of financial worth.

Abstract: Some embodiments include a computer-implemented method of predicting economical movements. The method can include: receiving financial statements of a group of firms within a geographical region; extracting accounting measurements from the financial statements; computing a macroeconomic index by aggregating at least a computed financial assessment overtime based on the accounting measurements across the group within the geographical region; and forecasting a macroeconomic activity within the geographical region based on the macroeconomic index.

Abstract: A three dimensional area of quiet is created by an active noise cancellation system comprising a reference microphone receiving background noise and sending the noise signal to an adaptive active noise canceller. An adaptive filter system using weights updated by a least mean squares method or other method generates an anti-phase signal which is broadcasted to counteract the background noise. The resulting residual noise or residual signal is sent back to the adaptive active noise canceller to reset the weights of the adaptive filter.

Abstract: A system and method monitors the emotional content of human voice signals after the signals have been compressed by standard telecommunication equipment. By analyzing voice signals after compression and decompression, less information is processed, saving power and reducing the amount of equipment used. During conversation, a user of the disclosed methodology may obtain information in various formats regarding the emotional state of the other party. The user may then view the veracity, composure, and stress level of the other party. The user may also view the emotional content of their own transmitted speech.
