摘要： A BLT can include a different channel length, channel width, or both to compensate for bit line loading effects. The channel length and/or channel width of the transistor structure can be configured so as to achieve a desired loading. Thus, the bit line transistor structure can improve global metal bit line loading uniformity and provide greater uniformity in bit line bias. Additionally, the greater uniformity in bit line bias can improve reliability.

摘要： A new concept of power amplifying apparatus and method is developed for adopting pre-distortion and applying to a radio communication system. The power amplifying apparatus includes a pre-distortion module for pre-distorting an input signal x(n) according to a pre-distortion function, and for outputting a pre-distorted signal z(n), a power amplifier for amplifying a signal obtained by digital-to-analog conversion of the pre-distorted signal z(n), a pre-distortion function producing module for receiving the pre-distorted signal z(n) and a signal y(n) obtained by analog-to-digital conversion of the fed-back output signal of the power amplifier, and for obtaining model coefficients cq,k,s that minimize the power of a modeling error signal e(n)=z(n)−y(n). The pre-distortion function used by the pre-distortion module is represented as z ⁡ ( n ) = ∑ q = 0 Q ⁢ ∑ k = 1 K ⁢ ∑ s = - S min ⁢ ⁢ ( S , q ) ⁢ c q , k , s ⁢ y ⁡ ( n - q + s ) ⁢  y ⁡ ( n - q )  k - 1 .

摘要： A desired acoustic signal is extracted from a noisy environment by generating a signal representative of the desired signal with a processor. The processor receives aural signals from two sensors each at a different location. The two inputs to the processor are converted from analog to digital format and then submitted to a discrete Fourier transform process to generate discrete spectral signal representations. The spectral signals are delayed by a number of time intervals in a dual delay line to provide a number of intermediate signals, each corresponding to a different spatial location relative to the two sensors. Locations of the noise source and the desired source are determined and the spectral content of the desired signal is determined from the intermediate signal corresponding to the noise source locations. Inverse transformation of the selected intermediate signal followed by digital to analog conversion provides an output signal representative of the desired signal. Techniques to localize multiple acoustic sources are also disclosed. Further, a technique to enhance noise reduction from multiple sources based on two-sensor reception is described.

摘要： A method for detecting accuracy of media advancement is disclosed. A first set of nozzles of a printhead imprints a first swath of prints on a media sheet. After the media sheet is advanced by a predetermined distance, a second set of nozzles located in front of the first set of nozzles in the direction of the media advancement imprints a second swath of prints on the media sheet. The degree of the alignment of these two swaths of prints then serves as an accuracy factor of the media advancement and the accuracy factor can then be ascertained.
