Inventor: HOUSE WILLIAM NEAL
IPC: H04S5/00
Filed: 2003-07-30
Abstract: A sound processing system adaptively mixes active matrix decoding and passive matrix processing of incoming audio signals.

Mixed output signals are generated with passive matrix processing where the audio signals are monaural. The sound processing system reduces the degree of active matrix decoding in the mixed output signals where the incoming audio signals are stereo and monaural. The sound processing system also generates virtual stereo signals from incoming audio signals having monaural signals. Mixed output signals are generated of the virtual stereo signals using active matrix decoding.

Title: Digital ink database searching using handwriting feature synthesis
Inventor: LAPSTUN PAUL
IPC: G10L15/00
Filed: 2002-10-15
Abstract: A system and method for ink database searching using handwriting feature synthesis is disclosed which allows a digital ink database to be searched using a text-based query. Using a writer-specific handwriting model derived from a handwriting recognition system or suitable training procedure, a text query is converted into feature vectors that are similar to the feature vectors that would have been extracted had the author of the digital ink database written the text query by hand. The feature vectors are then used to search the database. This allows the searching of a digital ink database when the only input mechanism available is text entry, and can allow a person other than the author of the digital ink database to search the digital ink database.
