摘要： In encoding, index information indicating a group of coefficients that minimizes the sum of the error between the value of each sample and the value is obtained by multiplying the quantized value of each of a plurality of samples by a coefficient corresponding to the position of the sample. The coefficient is selected from a plurality of groups of predetermined coefficients corresponding to the positions of the samples. In decoding, a plurality of values corresponding to an input vector quantization index are obtained as decoded values corresponding to a plurality of sample positions. With the use of a group of predetermined coefficients corresponding to the plurality of sample positions and indicated by input index information, the values obtained by multiplying the decoded values and the coefficients, corresponding to the sample positions are output.

摘要： A quantized normalization value and a normalization-value quantization index corresponding to the quantized normalization value are obtained, the quantized normalization value being obtained by quantizing a normalization value that is a value representative of samples. If a difference value that is obtained by subtracting a value corresponding to the quantized normalization value from a value corresponding to a magnitude of a value of each sample is positive and if the value of each sample is positive, the difference value is set as a quantization candidate. If the difference value is positive and if the value of each sample is negative, a value obtained by inverting positive/negative of the difference value is set as the quantization candidate. The plurality of quantization candidates respectively corresponding to the plurality of samples are collectively vector-quantized, and a vector quantization index is thus obtained and output. Sign information is output, the sign information expressing positive/negative of each sample that does not make the difference value positive, among the samples. Accordingly, encoding and decoding techniques capable of reducing musical noise and the like can be provided.

摘要： An object sensor for use with an automatic swing door includes a light emitter, which is mounted on a door surface of the automatic swing door. The light emitter emits a light beam toward a floor. A distance detector is mounted on the door surface. The distance detector receives the light beam reflected from an object and develops an output signal having a value representing the distance of the object from the distance detector. A control unit makes a judgment based on the value of the output signal of the distance detector as to whether the object is approaching the door surface. The control unit stores the value of the distance detector output signal representing the distance between the distance detector and the floor, as a reference value. A dead zone is defined for the reference value to extend from the floor to a predetermined distance above the floor. When the value of the distance detector output signal is outside the dead zone, the control units judges the object to be approaching the door surface.

摘要： In a CELP coding scheme, p-order LPC coefficients of an input signal are transformed into n-order LPC cepctrum coefficients c.sub.j (S.sub.2), which are modified into n-order modified LPC cepstrum coefficients c.sub.j ' (S.sub.3). Log power spectral envelopes of the input signal and a masking function suited thereto are calculated (FIGS. 3B, C), then they are subjected to inverse Fourier transform to obtain n-order LPC cepstrum coefficients, respectively, (FIGS. 3D, E), then the relationship between corresponding orders of the LPC cepstrum coefficients is calculated, and the modification in step S.sub.3 is carried out on the basis of the relationship. The modified coefficients c.sub.j are inversely transformed by the method of least squares into m-order LPC coefficients for use as filter coefficients of a perceptual weighting filter. This concept is applicable to a postfilter as well.
