A method and system of identifying text in a handwriting input is provided. The system includes a feature extractor (30) and a classifier (32). The feature extractor (30) extracts a plurality of features from handwriting input. The classifier (32) classifies the handwriting input according to a discriminant function that is based on a polynomial expansion. The text is identified according to the discriminant function output.

A computer-based method and system selects a plurality of training vectors for a pattern recognition system by creating a plurality of clusters and then uniformly sampling the clusters. Each of the clusters is associated with a particular class and includes a plurality of example signals. The example signals are assigned to the clusters as a function of cluster-example distances. If a cluster includes one or more overlapping example signals, the number of clusters associated with the overlapping cluster is increased and the example signals are re-assigned to the clusters.

The invention provides a computer-implementable method for detecting substroke boundaries in handwriting input. The method selects pen tip velocity extremas to represent. substroke boundaries. The method includes steps for generating a velocity profile from the handwriting input; identifying a plurality of peak extrema within the velocity profile; identifying a plurality of in-line extrema within the velocity profile; and detecting the substroke boundaries by filtering the plurality of peak extrema and the plurality of in-line extrema.

Listening capacity of a signal destination is augmented through the provision of a master switching center (207) and a slave switching center (209) linked via a dedicated communication port (203). Under direction of the master switching center (207), the slave switching center (209) sums communication system data signals received from shared communication ports (201) and presents the resulting summed communication data to the dedicated communication port (203). The master switching center (207) presents the summed communication data, received via the dedicated communication port (203), to the signal destination, thus augmenting listening capacity of the signal destination.

An operator MUX interface (OMI) (102) includes a data base manager (203) that manages at least two data bases. The first comprises a substantially non-temporary data base, and the second comprises a substantially temporary data base. The latter includes information from both the first data base, and other information as well. The data base manager (203) automatically alters the data storage structure of the second data base whenever either the data storage structure for the first data base is changed, or whenever new information must be added to the second data base, and the data storage structure of the second data base will not readily accommodate that addition.

In a digital summing process that sums non-linear digital signals by converting them to linear signals, computing their two's complement, summing the two's complements together and converting the resultant into a non-linear resultant, the fidelity of the summing process may be verified in the following manner. When only one non-linear digital signal is being summed, an algorithm determines whether the one non-linear digital signal being summed is equivalent to a predetermined value which, when passed through the summing process, will yield a different value than the one inputted. If the algorithm determines that the one non-linear digital signal is equivalent to a predetermined value, it sets a flag which indicates that the resultant over written with the predetermined value. Once the resultant is overwritten with the predetermined value, the flag is reset.

Method for assuring fidelity of a summing process

The present invention discloses a communication system network that comprises a plurality of communication systems and a processing multiplexer. The communication systems, which may be either conventional communication systems and/or trunked communication systems, transmit digitized audio signals and communication system data to the processing multiplexer. Based on signal destination data, which is part of the communication system data, the processing multiplexer processes the digitized signals and routes the resultant signals to the appropriate signal destinations of the communication systems.

The RF data communication band pass filter is a fixed device that filters both RF multi-level data signals and binary-level data signals. The RF data communication band pass filter comprises a low pass filtering means having a corner frequency of approximately 2900 Hertz and as high pass filtering means of approximately 340 Hertz. By using precision components the overall group delay envelope is such that both multi-level RF data signals and binary-level RF data signals are adequately filtered without substantial harmonic distortion or spectral distortion. In addition, the communication band pass filter meets the strictest of international RF data communication requirements.
