20110015880 | ULTRASONIC PROPAGATION TIME MEASUREMENT SYSTEM - High-quality and high-speed electronic pen drawing performance is ensured without being affected by noise of an ultrasonic signal which is generated by an apparatus using ultrasonic such as a motion detector. In an ultrasonic receiver for use in ultrasonic propagation time measurement, an external environment noise is measured to first determine a frequency. Thereafter, centered around the frequency, a band elimination filter having a several kHz band is structured as software to again measure an external environment noise. This sequence is repeated until a signal intensity lowers below a predetermined value. When the signal intensity fails to lower below the predetermined value even after a predetermined number of repetitions of the sequence, a transmission output on the side of an electronic pen as an ultrasonic transmission source is increased or an ultrasonic oscillation frequency is changed. | 01-20-2011 |

A plurality of ultrasonic signals generated based on a plurality of M sequences different from each other are propagated from a transmission side to a reception side, whereby the reception side executes processing of correlation between each model waveform of the plurality of M sequences and a waveform of each ultrasonic signal and detects a subsidiary peak of a correlation value appearing when both waveforms partly coincide with each other to, starting with the smallest one of subsidiary peaks detected by all the correlation processing, determine a plurality of corresponding M sequences. The transmission side selects an M sequence differing in each transmission cycle from among the determined plurality of M sequences and sends out an ultrasonic signal modulated by the selected M sequence and an electromagnetic wave signal to the reception side. The reception side calculates a value of correlation between the ultrasonic signal and a model waveform, detects a first main peak of the calculated correlation value and calculates an ultrasonic propagation time from a time point of the reception of the electromagnetic wave signal and a time point of the detection of the main peak. | 05-19-2011 |
