IPC: H03M7/30
Filed: 2004-07-02
Granted: 2005-12-21
Abstract: An apparatus for audio compression by using mixed wavelet packet and discrete cosine transformation techniques is provided. The apparatus uses wavelet packet frequency division to divide the audio signals into a plurality of sub-frequency bands through a plurality of filters. Then, based on the flatness in the time domain and the frequency domain, the apparatus determines whether to execute the discrete cosine transformation. By using the optimal bit allocation algorithm of a non-ideal synthesized filter, the apparatus transforms the minimum shielding threshold of the frequency domain derived by the psychoacoustic model into a shielding threshold on the wavelet domain to provide accurate quantization guideline. Then, the apparatus uses a quantizer, in combination with the wavelet domain shielding threshold, to greatly reduce the data amount and maintain the high audio quality. Finally, the entropy coding is used to code the quantized parameters and packets them into bit-streams. Thus, a better wavelet shielding threshold can be obtained, and the higher time resolution or frequency resolution can be selectively obtained to match the different music characteristics to obtain higher music quality.

Title: Bridge-less boost (BLB) power factor correction topology controlled with one cycle control
Inventor: SOLDANO MARCO
IPC: G05F/
Filed: 2004-09-30
Granted: 2007-04-21
Abstract: The bridgeless boost topology reduces the power dissipation, cost, and size of prior PFC systems by eliminating the intrinsic loss of the input rectifier bridge. Sensing of the input line voltage by the controller is unnecessary. The use of One Cycle Control (also known as Single Cycle Control) allows the Power Factor Correction function to be performed without complex rectification networks to obtain the AC line voltage reference. The use of bi-directional switches makes it possible to control inrush current (the startup over-current due to the charging of the output bulk capacitor), which allows elimination of over-current limiting devices and reduction of the diode surge capability requirements. Moving the boost inductor to the system input adds an additional filtering function, reducing the cost of input EMI filtering.
