Abstract:
In an first aspect, a ladder for mounting on a vehicle trailer includes an attachment bracket assembly for mounting on the trailer; a first side rail; a second side rail parallel to the first side rail; and a plurality of rungs pivotally connected to both the first and second side rails. The ladder is collapsible to decrease a distance between the first and second side rails. In a second aspect, a ladder for mounting on a vehicle trailer includes an attachment bracket; a first side rail; a second side rail parallel to the first side rail; a plurality of rungs connecting the first and second side rails; and a pivotal connection. The first and second side rails define a plane and the pivotal connection allows for rotation of the plane about a vertical axis. The pivotal connection is disposed between the attachment bracket and the first side rail.
Abstract:
The present invention is a synthetic speech encoding device that produces a synthetic speech signal which closely matches an actual speech signal. The actual speech signal is digitized, and excitation pulses are selected by minimizing the error between the actual and synthetic speech signals. The preferred pattern of excitation pulses needed to produce the synthetic speech signal is obtained by using an excitation pattern containing a multiplicity of weighted pulses at timed positions. The selection of the location and amplitude of each excitation pulse is obtained by minimizing an error criterion between the synthetic speech signal and the actual speech signal. The error criterion function incorporates a perceptual weighting filter which shapes the error spectrum.

Abstract:
The present invention is a method for determining linear predictive coding filter parameters for encoding a voice signal. The method includes sampling a voice signal, grouping the samples into a plurality of frames, generating a plurality reflection coefficients for each frame of samples, quantizing the reflection coefficients, generating spectral coefficients from the quantized reflection coefficients, selecting a quantized reflection coefficient having the smallest log-spectral distance between a quantized spectrum, and an unquantized spectrum and, converting the selected quantized reflection coefficient to linear predictive coding (LPC) filter coefficient.
Abstract:
Linear predictive coding (LPC) filter parameters are determined for use in encoding a voice signal. Samples of a speech signal using a z-transform function are pre-emphasized. The pre-emphasized samples are analyzed to produce LPC reflection coefficients. The LPC reflection coefficients are quantized by a voiced quantizer and by an unvoiced quantizer producing sets of quantized reflection coefficients. Each set is converted into respective spectral coefficients. The set which produces a smaller lag-spectral distance is determined. The determined set is selected to encode the voice signal.
Abstract:
A speech communication system using a code excited linear prediction speech decoder. The decoder using a first codebook containing a first digital value sequence selected from the set of binary values {0, 1}. The decoder also using a second codebook containing a second digital value sequence having values selected from the set of binary values {−1, 0}. The first digital value sequence and the second digital value sequence are combined to become a third digital value sequence having a set of ternary values from the set of {−1, 0, 1}.
