    摘要： A method of performing sound effect comprising providing a headphone-like or earphone-like device with rear speakers carried therein, wherein the headphone-like or earphone-like device includes an opening for receiving the front speaker signal. Then, the signal is transmitted to the front, rear and sub-woofer signal to associated speakers. The signal to the rear speakers is processed by HRTF and means for creating virtual speakers to obtain virtual speakers of the rear side. The processed signal is transmitted to the rear speaker.

    摘要： A medical device includes an elongate member defining a lumen and a tipless basket having a proximal end and a distal end. The basket is retractable within and extendable from the lumen. The basket includes a plurality of proximal legs extending from the proximal end of the basket and a plurality of distal legs extending to the distal end of the basket. Each of the plurality of proximal legs is connected to an end of at least two of the plurality of distal legs between the proximal and distal ends of the basket.

    摘要： System of multi-channel shared resistor-string digital-to-analog converters comprises a time-sharing interpolator converting the multi-channel digital audio input at low sample rate to the multi-channel digital audio output at high sample rate, a time-sharing sigma-delta modulator modulating the multi-channel digital audio input with a long sample wordlength from the interpolator to be a multi-channel digital audio output with a shorter sample wordlength, multi-channel shared resistor-string digital-to-analog converters converting the multi-channel digital audio input to be a multi-channel staircase analog signal output, and one low-order RC filter for each channel further attenuating the out-of-band noise in the analog staircase analog output, especially the high-frequency residue images.
