Abstract: A disk drive power system (200) is described. The system (200) is operable such that during power interruption, the system (200) taps electric power by rectifying the back-EMF generated across each winding (A, B, C) of a DC motor (216) and supplying power to a voice-coil motor (226) to park a read/write head (18) safely away from an associated magnetic disk surface.

Abstract: A method and apparatus for assigning an exponent coding strategy in a digital audio transform coder. Different coding strategies having different differential coding limits may be assigned to different set of transform exponents according to the frequency domain characteristics of the audio signal. A neural network processing system is utilised to perform an efficient mapping of each exponent set to an appropriate coding strategy.

Abstract: A method includes receiving a sequence of frames containing audio information and determining that a frame is missing in the sequence of frames. The method also includes comparing the frame that precedes the missing frame to the received frames to identify a selected frame. The method further includes identifying a replacement frame comprising the frame that follows the selected frame. In addition, the method includes inserting the replacement frame into the sequence of frames in place of the missing frame.

Abstract: A Yule-Walker based, low-complexity voice activity detector (VAD) is disclosed. An input signal is typically noisy speech (i.e., corrupted with, for example, babble noise). In one embodiment, a first initialization stage of the VAD computes an occurrence of a silent period within the input signal and the AR parameters. The VAD could accordingly compute a tentative adaptive threshold and output hypothesis H 1 (which means speech is present) during this stage. During the second initialization stage, the VAD generally builds a database of associated values and computes the adaptive threshold accordingly. The second initialization stage could also output tentative VAD decisions based on the tentative threshold computed in the first initialization stage. Finally, the VAD periodically retrains or updates AR parameters, threshold values and/or the database and outputs VAD decisions accordingly.

Abstract: In order to reproduce audio signals which have been compressed or encoded for storage or transmission using, for example, MPEG audio encoding, a synthesis sub-band filter is employed which performs an inverse modified discrete cosine transform. The computational cost of the IMDCT implementation is reduced by pre-calculating arrays of sum and difference data. The arrays of sum and difference data are then used in two separate transform calculations, the results of which can be used in the generation of pulse code modulation audio data.
