A circuit is provided that includes summing circuit for comparing the pwm output signal to the pwm input signal and producing an increment signal if a value of the pwm input signal exceeds a corresponding value of the pwm output signal and producing a decrement signal if a value of the pwm input signal is less than a corresponding value of the pwm output signal. An integrator produces a duty cycle signal by producing an increase in value of the duty cycle signal in response to each increment signal and a decrease in value of the duty cycle signal in response to each decrement signal.

Compact transceiver architecture for achieving device to device (d2d) communication using uplink and downlink carrier frequencies
A system and method for device-to-device (d2d) communication is disclosed. A preferred embodiment comprises a frequency synthesizer configured to provide a first carrier frequency and a second carrier frequency, an up-converter coupled to the frequency synthesizer and configured to up-convert a first baseband signal into a cellular uplink signal when receiving the first carrier frequency from the frequency synthesizer, and configured to up-convert the first baseband signal into a first device-to-device signal when receiving the second carrier frequency from the frequency synthesizer, and a down-converter coupled to the frequency synthesizer and configured to down-convert a second device-to-device signal into a second baseband signal when receiving the first carrier frequency from the frequency synthesizer, and configured to down-convert a cellular downlink signal into the second baseband signal when receiving the second carrier frequency from the frequency synthesizer..

Conference call service with speech processing for heavily accented speakers
Speech recognition processing captures phonemes of words in a spoken speech string and retrieves text of words corresponding to particular combinations of phonemes from a phoneme dictionary. A text-to-speech synthesizer then can produce and substitute a synthesized pronunciation of that word in the speech string.

Interactive synthesizer hoop instrument
A hoop containing lights (leds or el wires) that vary output, based on, for example, movement of the user, through the use of electromechanical and electronic sensors and switches is disclosed. Different movements, circuits or programs cause the lights to respond differently to the same signals.

Communication apparatus and communication method
A modulator generates a modulation signal from an input signal, and a serial-parallel converter generates a subcarrier modulation signal from the modulation signal. An ifft unit performs an inverse fast fourier transformation on the subcarrier modulation signal, and a decomposer decomposes a calculation result into a real part data and an imaginary part data.

Multi-carrier communication apparatus
A local carrier wave output from a synthesizer to quadrature demodulators is multiplied by an offset that makes a frequency shift by an integer number of subcarriers in units of sub-carrier bands. The offset is set to a value obtained by multiplying the number sequentially counted up from 0 to the number of unused sub-carriers included in guard tones in a signal band by the bandwidth of a sub-carrier.
