Abstract: A power converting device includes a switching unit, a resonant unit, a converting unit, a rectifying and filtering unit, an inductance-sensing unit, and a driver. The resonant unit is electrically connected to the switching unit and includes a resonant capacitor, a resonant inductor, and a variable magnetizing-inductor having at least two inductances, the resonant inductor is electrically connected to the resonant capacitor and the variable magnetizing-inductor. The converting unit is electrically connected to the resonant unit. The rectifying and filtering unit is electrically connected to the converting unit. The inductance-sensing unit is electrically connected to the rectifying and filtering unit, the inductance-sensing unit instantaneously senses inductances of the variable magnetizing-inductor.

Abstract: The present invention discloses apparatus and method for fast and robust automatic gain control (AGC). By using the power statistics and/or the amplitude statistics of multiple pairs of signed ADC outputs, the additional gain control can be determined and included in a statistics-aided AGC to successfully complete the AGC function for a received signal having a dynamic range up to 100 dB within a few micro-seconds.

Abstract: The present invention provides a replaceable micro-surgical instrument which comprises a pull structure and a hollow tube attached to a grip. The hollow tube has a sleeve at one end with a U-type elastic element sliding in. The U-type elastic element includes a spring tension section and two opposite extending arms and the outer edge of each arm is against the inner wall of the sleeve. Two arms could move according to the pull structure to selectively extend out of the sleeve to be opened or pull back into the sleeve to be clip together. Particularly, there is a replaceable micro-surgical element set in the front-end of each arm, so when the micro-surgical element becomes blunt or broken, the doctor could only replace the micro-surgical element without replace a whole new instrument in order to reduce instrument cost, increase replacement rate, and maintain the quality of medical surgery.

Abstract: The present invention discloses an apparatus and method for power-saving switch on a pair of configurable analog-to-digital converters. The apparatus mainly comprises an antenna, an antenna switch, a zero-IF RF receiver, and a baseband demodulator. By using a first and a second control signal to control the ON/OFF states of a plurality of switches and a plurality of stage units in the configurable analog-to-digital converters, and the third control signal to control the ON/OFF states of a plurality of LNA stages and the gain of a plurality VGAs, the power saving of the analog-to-digital converter is easily achieved.

Abstract: A glassy metal composite material includes: a Mg-based amorphous metal matrix; and a plurality of porous metal particles dispersed in the Mg-based amorphous metal matrix. The Mg-based amorphous metal matrix penetrates into pores in the porous metal particles. The porous metal particles have a hardness less than that of the Mg-based amorphous metal matrix.
