    Abstract: A programmable integer and fractional frequency divider is provided. The programmable divider divides a frequency of an input signal by a first divisor to generate an output signal, and comprises a programmable integer frequency divider and a fractional number switch. The programmable integer frequency divider divides the frequency of the input signal by a second divisor to generate the output signal, wherein the second divisor is first or second integers depending on a divisor switching signal. The fractional number switch calculates a pulse count of the output signal, and generates the divisor switching signal to switch from the first to the second integer when the pulse count of the output signal equals to a predetermined pulse count determined by a fractional part of the first divisor, and receives a fractional divisor control signal to change the predetermined pulse count, thereby changing the fractional part of the first divisor.

    Abstract: A system for switching an opened window in a computer system between a display state and a hide state includes a mouse and a window switch system. The mouse has a switch key and a signal control unit. The window control system includes a window recording unit, a display control module, a window state switch module and a signal processing unit. When the user presses the switch key to output a switch signal from the mouse to the window control system, the window state switch module changes the state of the opened window, and then, the display control module executes the altered result and outputs the result to the screen in the computer system, thereby achieving the purpose of switching the computer window between the display and the hide states, so as to prevent the information shown on the screen from being seen by unauthorized persons.

    Abstract: A method for executing a first and a second task in M time units is disclosed. The method includes comparing the priority of the first task and the task. If the first task has a higher priority than the second task, the first task is executed. The first task is then suspended after the first duration, and the second task is executed for a second duration.

    Abstract: A method of decoding interleaved Reed-Solomon codes to achieve an improved performance for burst errors is described. The method takes advantage of both interleaving and erasure decoding to increase the error correcting capability of a system without necessarily depending on channel reliability information. The observed correlation of burst errors in interleaved systems is advantageously used to achieve an improved error-correcting system, wherein a first code word is decoded, and the error locations in the first codeword are used to determine erasures for the remaining code words in the same interleaving block, and finally, decoding the remaining code words in parallel.

    Abstract: A sequence based indexing and retrieval method for a collection of text documents includes the steps of generating a query token sequence from a query; generating at least a representative token sequence from each of the documents that contain at least one token of the query token sequence; measuring a similarity between each of the representative token sequences and the query token sequence; and retrieving the text document in responsive to the similarity of the representative query token sequence with respect to the query token sequence. The similarity measurement is preformed by determining a token appearance score, a token order score, and a token consecutiveness score of the representative token sequence with respect to the query token sequence, so as to illustrate the similarity between the representative token sequence and the query token sequence for precisely and effectively retrieving the text document.

    Abstract: A receiver for a received signal having two or more different data levels comprises two or more channel estimators, (at least) one channel estimator for each different data level, where each channel estimator preferably implements an adaptive 2nd order or higher model of the transmission channel over which the received signals was transmitted to generate an estimated signal for one of the different data levels. The receiver also has a comparator that compares the current received signal to the estimated signals generated by the different channel estimators to select an output data value for the current received signal. The adaptive model of the transmission channel has coefficients that are dynamically controlled based on an error signal generated by the comparator. Each channel estimator relies on an output signal generated by an adaptive equalizer. In preferred shared-component implementations, each adaptive equalizer is shared by two or more different channel estimators, and, in one possible preferred shared-component implementation, all of the different channel estimators share a single adaptive equalizer.
