    摘要： The present invention relates to a harmonic-noise speech coder and coding algorithm of the mixed signal of voiced/unvoiced sound using harmonic model. The harmonic-noise speech coder comprises a noise spectral estimating means for coding the noise component by predicting the spectral by LPC analysis method after separating the noise, which is unvoiced sound component from the inputted LPC residual signal using cepstrum. And more improved speech quality can be obtained by analyzing noise effectively using the noise spectral model predicted through cepstrum-LPC analysis method of the mixed signal of voiced/unvoiced sound to the existing harmonic model and then coding the signal.

    摘要： A time-separated speech coder that codes a transitional signal of voiced/unvoiced sound through harmonic speech coding, the coder including a transitional excitation signal analyzer/synthesizer for coding the transitional signal by extracting the harmonic model parameters of both transitional analyzers after detecting a transitional point and generating sinusoidal waveforms according to a variable transitional point separating both transitional analyzers. By the transitional point at which energy varies abruptly and the time-separated coding based on the transitional point, more improved speech quality than in the general harmonic speech coder can be obtained using the time-separated speech coder by increasing the representation capability of the transitional signal with large energy variation, after adapting it to the variable transitional point.

    摘要： The presently disclosed Lifter comprises a substantially level horizontal, partially or totally tracked, overhanging bar, which is supported by the roof of a vehicle. The tracked bar is held up against the upper door frames by a ratcheted strap over the roof and in between two open doors on each side of the vehicle. Another ratchet attached to the bar via a trolley is usable for lifting the object, and the trolley allows for its horizontal movement along the tracked bar. Particularly, the object may be an incapacitated person such as a patient. Even more particularly, the patient may be held and restrained in harness-type garment comprising a lifting loop. Generally, the Lifter may be used to lift any heavy object in and out of a vehicle using mechanical leverage. In some embodiments, the bar comprises two shorter C channels removably joined, or a shorter channel with a telescoping extension. Thus, the presently disclosed lifter is very easy to carry, store, and generally handle as an auto accessory.

    摘要： The present disclosure provides a self-adjusting garment for lifting or lowering a wearer. It has three functionally necessary and sufficient elements, two weight bearing straps and a connecting isosceles trapezoidal fabric. These elements provide three self-adjusting openings for the legs and torso and a loop usable in combination with a lifting mean, such as a hook. In some embodiments, the connecting isosceles trapezoidal fabric has an opening usable for discharging bodily wastes. The self-adjusting garment accommodates and adapts to wide range of body sizes and shapes automatically. When suspended, the wearer's weight automatically secures and safely restrains the wearer.
