Abstract: A method for reconstructing a fingerprint image from a plurality of frames captured from swipe fingerprint sensor is disclosed. The method is based on a motion estimation between consecutive fingerprint frames. Only a portion of each frame is used to obtain the motion estimate to minimize system resources necessary for reconstructing the fingerprint image.

Abstract: The method and system of present invention sequences audio post-processing algorithms to simulate live or theater sound. An audio signal is selectively post-processed according to equipment availability and listener preferences. Downmixing or Prologic algorithms are applied to a signal arriving at sound system. A listener inputs their speaker configuration to a player console. Desired post-processing effects are likewise indicated to the console. For instance, if surround sound equipment is both available and selected, then surround portions of the audio signal are parsed to surround speakers. Bass management techniques then transfer low frequency channels of the signal to compatible speakers. VES or DCS algorithms further manipulate the surround portion of the signal to create an illusion of immersion, and a center channel equalizer balances the signal playback. Alternatively, the post-processed signal is transmitted to a headphone set.

Abstract: In accordance with an embodiment of the present invention, an efficient and accurate system and method are described for detecting a fingerprint from swipe sensor system. A swipe sensor module is coupled to a microprocessor module. The swipe sensor module collects fingerprint image data as a plurality of frames and passes the frames of data to the microprocessor module. The microprocessor module assembles the frames of data into a complete image of the fingerprint that is cropped and processed to remove noise and artifacts. The cropped image is used to generate a template in a first instance and to compare an extracted portion of the cropped image to existing templates in a second instance.

Abstract: A method, apparatus and program product facilitates the sharing of memory resources between exclusive audio post-processes. A program identifies post-processing applications that execute at different instances and assigns to them a common memory block. An audio packet arrives at a digital signal processor (DSP). The DSP associates a frame of the packet with a post-process. The DSP buffers the frame to a memory block that corresponds to the post-process. Upon releasing the buffered frame, the DSP prepares the memory block for use with a second post-process and frame.

Abstract: A bitstream is sampled at an interval predetermined as a function of available processing power and memory storage capacity. The sampled bits are evaluated against a first layer Huffman decoding subtable. The subtable obtains the address of a second layer subtable from an indexed location identified by the sampled bits. A second bit sample is parsed to the designated second layer subtable, which outputs either an address for a third layer subtable, or a symbol and an associated code length.
