摘要： A data processing circuit comprises an encoder circuit for encoding a data word, wherein each digit may have any one of three or more digit values. The data word is encoded so that digit counts in the data word satisfy predetermined criteria (the digit counts are counts of the numbers of the digits in the encoded data word that assume respective digit values). The encoder defines at least two digit maps, each digit map defining assignments of each of the available digit values to a respective different output digit value. The encoder selects at least two groups of digits within the input data word. Each group is associated with a respective one of the digit maps, the groups being selected so that when each digit map has been applied selectively to the digits from its associated group, digit counts of the number of times respective digit values occur in the data word will satisfy predetermined criteria. A data signal is generated that represents the input data word by information that identifies the selected groups and an output data word obtained by mapping the digits of each group in the input data word according to the digit map for that group.

摘要： A method of pre-processing gesture signals comprises the step of Filtering one or more signal segments by applying an infinite impulse response (IIR) filter both in a forward and in a backward temporal direction, so as to produce a band-limited gesture signal. The method may further comprise the step of matching the forward and backward initial conditions of the IIR filters to avoid any transients. Unevenly or sparsely sampled gesture signals may be subjected to the preliminary steps of interpolating the sampled signal, resampling the interpolated signal at a relatively high resampling frequency, filtering the resampled signal, and optionally downsampling the filtered signal, so as to produce a gesture signal having a well-defined sampling rate. An additional compression step may be carried out. The method may be utilized in conjunction with handwriting recognition methods.

摘要： This invention relates generally to devices for location positioning and more particularly relates to a system for identifying an environmental source emitting a base frequency and waveform signal. A sensor (101) records an environmental source (105) emitting a base frequency and waveform signal, the signal being amplified (102), digitized (103), processed and compared (104) with a stored unique waveform characteristic. On the basis of the comparison result(s), location positioning and/or a device orientation may be determined. The invention further relates to a method and a computer readable medium containing a program for making a processor carry out the method.
