    摘要: The transmitter of a wireless power transmission audio system includes: a transmission signal generating section for generating a transmission signal comprised of an RF signal; a first resonant circuit which receives and sends out the transmission signal; a detecting section for sensing a variation in the transmission signal; and a transmission signal adjusting section. The loudspeaker of the system includes: a second resonant circuit for receiving the transmission signal by producing a magnetic field resonant coupling phenomenon; and an audio output section for reproducing the audio signal. At least one of the transmitter and the loudspeaker includes an impedance adjusting section which changes an impedance value on the transmission line of the transmission signal. When the impedance adjusting section changes the impedance value, the transmission signal adjusting section changes the signal waveform of the transmission signal.

    摘要: A wireless power transmission system transmits power wirelessly from a power transmitter to a power receiver. The power transmitter includes a class E amplifier, a transmitting-end resonant circuit, a detector that detects a voltage or current waveform at a predetermined position in the class E amplifier in accordance with the impedance of the transmitting-end resonant circuit as viewed from the class E amplifier, and a signal extractor that extracts a signal according to the waveform. The power receiver includes a receiving-end resonant circuit, a rectifier circuit, a power reproducing section, and an impedance changer connected between the rectifier circuit and the power reproducing section to change its impedance. When the impedance is changed, the detector detects the waveform variation and the signal extractor extracts and outputs a signal corresponding to the waveform detected by the detector.

    摘要: A model application unit calculates linear prediction coefficients of a multi-step linear prediction model by using discrete acoustic signals. Then, a late reverberation predictor calculates linear prediction values obtained by substituting the linear prediction coefficients and the discrete acoustic signals into linear prediction term of the multi-step linear prediction model, as predicted late reverberations. Next, a frequency domain converter converts the discrete acoustic signals to discrete acoustic signals in the frequency domain and also converts the predicted late reverberations to predicted late reverberations in the frequency domain. A late reverberation eliminator calculates relative values between the amplitude spectra of the discrete acoustic signals expressed in the frequency domain and the amplitude spectra of the predicted late reverberations expressed in the frequency domain, and provides the relative values as predicted amplitude spectra of a dereverberation signal.

    摘要: An optical receiving device capable of outputting a control signal and a data signal received as an optical signal, even if a received optical power of an optical signal inputted via an optical fiber 7 fluctuates. An optical-to-electrical conversion section 2 converts the optical signal inputted via the optical fiber 7 to an electrical signal. A received optical power detection section 3 detects a received optical power of the optical signal. A detection level setting section 4 outputs a first detection level value or a second detection level value as a detection level. A comparison section 5 compares the received optical power with the detection level. An output/stop switching section 6 outputs an electrical signal as an output signal when the received optical power is greater than the detection level, and stops outputting the signal when the received optical power Pt is smaller than the detection level Lt.

    摘要: A sound source model storage section stores a sound source model that represents an audio signal emitted from a sound source in the form of a probability density function. An observation signal, which is obtained by collecting the audio signal, is converted into a plurality of frequency-specific observation signals each corresponding to one of a plurality of frequency bands. Then, a dereverberation filter corresponding to each frequency band is estimated by using the frequency-specific observation signal for the frequency band on the basis of the sound source model and a reverberation model that represents a relationship for each frequency band among the audio signal, the observation signal and the dereverberation filter. A frequency-specific target signal corresponding to each frequency band is determined by applying the dereverberation filter for the frequency band to the frequency-specific observation signal for the frequency band, and the resulting frequency-specific target signals are integrated.
