Optical transmitter apparatus

An optical DQPSK modulator comprises a pair of phase modulators. Each of the pair of the phase modulators is provided with first and second driving signals. The first and second driving signals are amplified by first and second amplifiers, respectively. An RZ intensity modulator generates an optical RZ-DQPSK signal from an optical DQPSK signal output from the optical DQPSK modulator. A photodetector generates a monitor signal from the optical RZ-DQPSK signal. A gain adjuster unit adjusts the gains of the first and second amplifiers so as to minimize the power of the monitor signal.

Chaos therapy method and device

A therapy device, in its preferred embodiment, incorporates a chaos signal generator into a therapeutic massager for the purpose of increased therapeutic effectiveness in such areas as pain management, inducing calm, increasing mental clarity, interrupting repeating thoughts and emotions, and enhancing states of human awareness, such as mental analysis and intuitive functioning, by applying specific frequency bands of a highly unpredictable chaotic signal.

Portable electric device with power failure recovery and operation method thereof

A portable electronic device with power failure recovery, powered by a main power source, the device comprising a power detection module, a processor, a timing unit and a power management unit. The power detection module detects an output characteristic from the main power source and asserts an interrupt signal if the characteristic is below a threshold value. The processor asserts a turn-off signal and an enable signal in response to the interrupt signal. The timing unit asserts a notification signal at a predetermined time interval when the enable signal is asserted. Upon receipt of the turn-off signal, the power management unit disconnects the main power source from a circuit block. Moreover, the power management unit reconnects the main power source to the circuit block when the notification signal is asserted and the output characteristic of the main power source is beyond the threshold value.
