The invention improves the encoding and decoding of speech by focusing the encoding on the perceptually important characteristics of speech. The system analyzes selected features of an input speech signal, and first performing a common frame based speech coding of an input speech signal. The system then performs a speech coding based on either a first speech coding mode or a second speech coding mode. The selection of a mode is based on characteristics of the input speech signal. The first speech coding mode uses a first framing structure and the second speech coding mode uses a second framing structure.

A transmission system can perform flow control even if a flow control instruction is invalidated, and even when the transmission system malfunctions, it can autonomously recover to normal operation for communications. A flow control instruction sender has at least one of two functions including a normal transmission mode to send a flow control instruction for flow control over a congestion state if an event, such as the occurrence of a congestion or the removal of a congestion, occurs when a data receiver receives data, and an autonomous transmission mode to select one of a plurality of congestion states at present in each period and autonomously send a flow control instruction corresponding to the selected congestion state. The flow control instruction sender preferentially sends a flow control instruction in the normal transmission mode in which a congestion actually occurs or is actually removed, when timings of the normal transmission mode and the autonomous transmission mode coincide with each other. A flow control instruction receiver receives a flow control instruction to perform flow control by stopping sending data and sending data.

A polyphase inverter employs multiple power semiconductor switches both for its operation and to distribute the current and heat loads for improved operation and cooling. The inherently high currents required for motor operation are divided among a plurality of smaller conductors and semiconductor switches, making a printed wiring board feasible both for power distribution and for control. The approach also permits shorter path lengths to the switches, reduced inductance, faster possible operation of the power switches, and reduced transient activity outside of the immediate switch area. Signals derived from various power points can enable the controller to assess actual current and power distribution and to apportion losses appropriately, or to limit total power output should the losses be deemed excessive.

The invention relates to a semiconductor structure for electrostatic discharge protection, which includes a ground gate NMOS, and the ground gate NMOS has a substrate, a gate, a source and a drain. A plurality of contact plugs are formed on the source and drain sides. A plurality of first-level vias are electrically coupled to the GGNMOS and have a substantially asymmetrical layout in the source and drain regions. One or a group of second-level vias directs the ESD current to the desired first-level vias. The uniformity of current flow in the GGNMOS is thus improved.

The invention relates to a grayscale image enhancement method based on a stochastic resonance mechanism of a delayed self-feedback FHN (fitzhugh-nagumo) model. A traditional method has no good effect in absence of noise model prior knowledge. The grayscale image enhancement method includes steps of performing row scan for the noise-contained grayscale images at first, acquiring one dimensional sequence formed by various pixel gray values, and normalizing various factors of the one dimensional sequence; inputting the normalized one-dimensional sequence into the delayed self-feedback FHN neuron model so as to enable system output to achieve the best state of the stochastic resonance; restoring the outputted sequence as an image pixel value range in an inverted normalization manner, and restoring the image pixel value range as grayscale images; and then performing column scan for the restored grayscale images by repeating the process, and finally acquiring the reinforced grayscale images after row scan and column scan. Since dimension reduction of the images is realized in a row direction and a column direction, peer to peer relationship of two-dimensional images in row and column directions is effectively improved, and retention of space structure characteristics of the grayscale images which are processed by the stochastic resonance is facilitated.

The invention discloses a silicon-based high-rejection-ratio single-sideband modulator chip which comprises a silicon-based dual-parallel Mach-Zehnder modulator (DP-MZM) with an adjustable splitting ratio and a notch filter. A continuous optical signal is input into the silicon-based double-parallel Mach-Zehnder modulator, a microwave signal to be modulated is divided into two paths of signals with equal amplitude and 90-degree phase difference through the 90-degree bridge, and the two paths of signals are respectively input into a radio frequency input end of the silicon-based double-parallel Mach-Zehnder modulator to realize an optical single-side-band signal. The splitting ratio adjustable splitter based on a 1 * 2 Mach-Zehnder interference structure is introduced to independently adjust the split light of two arms of the two modulators arranged in parallel and the main modulator, and the asymmetry of the modulators introduced by process errors and the like is effectively compensated. The notch filter further filters stray sidebands, and the sideband rejection ratio of the single sideband signal is improved. The invention has the advantages of large working bandwidth, high rejection ratio and the like.

The present invention is directed to musical instruments that are based on the operation of an air reed and, in particular, encompasses end-blown flutes comprising an acoustic air space and a fluid air space. The communication between the acoustic and fluid air spaces is positioned so as to minimally interfere with the flow of air introduced, i.e., blown, into the fluid space and enables the instrument to produce rich, in-tune tones across a three octave range. The acoustic air space is formed by a hollow tuning chamber positioned opposite the air reed. In alternate embodiments, the invention encompasses a head-joint of a musical instrument, which head joint comprises a an acoustic space and a fluid space. The head joint of the invention may be used to replace or in place of the head joint or mouthpiece of common musical instruments of the woodwind family, e.g., the Western flute, saxophone, clarinet, oboe, nay, shakuhachi, or recorder.
