Abstract: A liquid crystal display apparatus to which the present invention is applied has a first data conversion circuit and a second data conversion circuit. The first data conversion circuit converts each predetermined number of display data included in prepared display data into pixel data in which the respective display data are arranged in a predetermined arranging order and in time-series. The second data conversion circuit is provided for each the predetermined number of signal lines included in the display apparatus and sequentially applies display signal voltages corresponding to the pixel data to the predetermined number of signal lines respectively. The liquid crystal display apparatus equalizes the amounts of charges to be written in respective display pixels by reversing the arranging order of the display data in the pixel data and the order of applying the display signal voltages to the signal lines per field period or per horizontal scanning period.

Abstract: An adaptive controller for an ESPAR antenna randomly perturbs a bias voltage vector V(n) composed of elements of bias voltage values Vm by a random vector R(n) generated by a random number generator, compares an objective function value J(n) of a cross correlation coefficient for a bias voltage vector V(n) before the perturbation with an objective function value J(n+1) of a cross correlation coefficient for a bias voltage vector V(n+1) after the perturbation, and selects and sets the bias voltage Vm corresponding to that when the cross correlation coefficient increases before and after the perturbation. Then the adaptive controller repeats the random perturbation and setting from the bias voltage of respective varactor diodes. This leads to that it is not necessary to provide a long training sequence signal, and the control process can be executed with learning so that a performance can be improved every iteration for search.

Abstract: In an LSP sound synthesizer, LSP transform parameters for three types of sounds are prestored: human, bird, and insect. For synthesis, the inverse transform is modified to increase the quality of each type of sound: a parameter converter uses a uniform-frequency distribution (of gain) for human, a mid-frequency concentration for bird, and a high-frequency concentration for insect sounds.

Abstract: A key-in device has a key-in section with a matrix array of keys. A key-actuated signal corresponding to a handwritten character input by the key-in section is input to an input pattern memory of a character recognition section, where an input pattern is formed and stored. The character recognition section has a standard pattern memory, having stored the standard pattern of a character to be recognized. A first feature detecting section extracts feature data from the input pattern in the input pattern memory. A first matching section detects a standard pattern coincident with the feature data extracted from the first standard pattern memory, and produces the character data input by the key-in section as a recognizable character.

Abstract: An LSP synthesizer (Line Spectrum Pair) includes an LSP voice synthesizer digital filter arranged for parallel operation upon voice parameters and excitation information, to obtain an LSP synthesized sound. The LSP voice synthesizer digital filter includes at least a parallel multiplier and a parallel adder. The parallel multiplier divides data into a set of upper bits and a set of lower bits and multiplies the upper and lower bits separately at specified different timings. The multiplication results are supplied to a delay circuit which adjusts timings of the multiplication results. These multiplication results are synthesized by the parallel adder to obtain a single piece of data.
