Abstract: A method for providing a priority-based, low-collision distributed coordination function (DCF) in a wireless network is provided. The network includes an access point and a plurality of stations. The method includes receiving at a first station a super-frame from the access point. The super-frame is operable to define a service period for each of the stations. A priority for the first station is determined based on the super-frame. A back-off time is selected for the first station based on the priority.

Abstract: The present disclosure provides a digital audio signal processing system that comprises a set of delay lines, allpass and lowpass filters to achieve the reverberation effect. The present disclosure further provides a method for generating and controlling digital reverberations for audio signals. The reverberation generated will have an increasing echo density in the time domain and a faster decay of high frequency signals than low frequency signals. The controlling mechanism of reverberation generation is realized through the extraction of the real environment characteristics.

Abstract: A system and method for processing a wafer includes a charge neutralization system. The wafer processing system includes a wafer measuring device that can measure characteristics of a surface of the semiconductor wafer. One or more wafer processing stations perform a chemical mechanical polish (CMP) process on the wafer surface. A desica cleaning station can clean and dry the semiconductor wafer. The wafer processing system further includes a charge neutralizing device that can alter a surface charge of the wafer surface.

Abstract: A method for stereo audio perceptual encoding of an input signal includes masking threshold estimation and bit allocation. The masking threshold estimation and bit allocation are performed once every two encoding processes. Another method for stereo audio perceptual encoding of an input signal includes performing a time-to-frequency transformation, performing a quantization, performing a bitstream formatting to produce an output stream, and performing a psychoacoustics analysis. The psychoacoustics analysis includes masking threshold estimation on a first of every two successive frames of the input signal.

Abstract: A system and method is disclosed for improving solder joint reliability in an integrated circuit package. Each terminal of a quad, flat, non-leaded integrated circuit package is formed having portions that define a solder slot in the bottom surface of the terminal. An external surface of the die pad of the integrated circuit package is also formed having portions that define a plurality of solder slots on the periphery of the die pad. When solder is applied to the die pad and to the terminals, the solder that fills the solder slots increases the solder joint reliability of the integrated circuit package.

Abstract: A Digitial Radio Mondiale (DRM) receiver and demodulation method includes a programmable downsampler and a programmable N-point Fast Fourier Transform (FFT) to recover and demodulate the OFDM symbols in a received DRM-encoded RF signal. The received signal is digitally sampled at a rate operably integer downsampled to achieve a number N samples in the useful portion of the OFDM symbol for input to an N-point FFT, where N equal to a power of two. The downsampling rate and size (N-points) of the FFT depend on the DRM encoding and transmission parameters, notably the robustness mode and spectrum occupancy. This reduces the processing/computational requirements and the design complexity of the DRM receiver.

Abstract: Internet Protocol address prefixes are hashed into hash tables allocated memory blocks on demand after collisions occur for both a first hash and a single rehash. The number of memory blocks allocated to each hash table is limited, with additional prefixes handled by an overflow content addressable memory. Each hash table contains only prefixes of a particular length, with different hash tables containing prefixes of different lengths. Only a subset of possible prefix lengths are accommodated by the hash tables, with a remainder of prefixes handled by the content addressable memory or a similar alternate address lookup facility.
