Title: Coder for incorporating extra information in a digital audio signal having a predetermined format, decoder for extracting such extra information from a digital signal, device for recording a digital signal on a record carrier, comprising such a coder, and record carrier obtained by means of such a device
Inventor: DRUYVESTEYN WILLEM FREDERIK
IPC: G10L19/018
Filed: 1989-11-08
Granted: 1995-02-22
Abstract: A coder for incorporating extra information in the form of an auxiliary signal in a digital audio signal having a predetermined format as well as a decoder for extracting this extra information from this digital signal, whilst the digital audio signal having the predetermined format is divided into frequency sub-bands, in which on the basis of psychoacoustic qualities of the human auditory system a relatively large amount of quantization noise is permissible, and the samples in each of these sub-bands are quantized relatively coarsely according to a preset criterion, whilst the quantized sub-band signals are summed with samples of the auxiliary signal, whose maximum amplitude is always smaller than a half quantization step of the relevant sample of the main signal; the summed sub-band signals are then reconstructed to a signal covering the entire frequency band, converted into a digital signal having the predetermined format and recorded or transmitted. In an unmodified receiver or reproducing device the original digital audio signal can be reproduced in a conventional way whereas the auxiliary signal remains masked. In a receiver or reproducing device comprising a decoder the signal is again divided into an equal number of frequency sub-hands in a way corresponding to that used in the coder and they are re-quantized according to the criterion applied in the coder. By subtracting per sub-band the quantized signal from the non-quantized signal, sub-bands of the auxiliary signal are formed, which are reconstructed into a replica of the complete original auxiliary signal. The coder can be employed in a device for recording a digital signal on the record carrier. Thus, record carriers can be obtained which are provided with a copy inhibit code and which are thus protected against unauthorized copying. If a signal containing such a copy inhibit code is to be recorded again this inhibit code is detected and recording can be inhibited, the signal to be recorded can be distorted seriously and/or the presence of the copy inhibit code can be signalled.

Abstract: An indoor air purifier has a container with a layer of soil supported above a lower air plenum. Room air is drawn downwardly through the layer of soil and discharged from the plenum back into the room. Contaminant gases in the air are adsorbed in the soil and metabolized by microorganisms, producing carbon dioxide and water, and substantially reducing noxious and toxic materials in the air. The soil may be divided into two layers, and the air purifier operated in either of two modes. During normal operation, air is drawn through both layers of soil for removal of particles and destruction of contaminants by microorganisms. Alternatively, air may be drawn through only one layer of soil at a substantially higher flow rate for removing particulate materials. Plants may be grown in the upper portion of the soil to aid in air purification and to provide an attractive room decor.

Abstract: A process is disclosed for direct isolation of captopril from a substrate of the formula <CHEM> wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.

Title: Device for reloading air craft containers
IPC: B64F1/32
Filed: 1990-02-09
Granted: 1992-12-09
Abstract: The device for reloading aircraft containers comprises a self- propelled transporter (1) and a transport trailer (2). The device is capable, on the one hand, of reloading a container from the transporter onto a trailer and, on the other hand, a container from the trailer onto the transporter. Since the transporter is provided in a known fashion with a roller track (9) and drive rollers (8), the first-mentioned reloading process presents no difficulty. By contrast, the trailer is provided only with roller tracks (5) and has no transport rollers of its own. Now, however, the transporter is provided in a novel fashion with an extendable tongue (4) with the aid of which it can pull a container from the trailer via the roller track thereof onto the transporter's own roller tracks (9). The trailer (2) is provided with a turntable (15) which permits its roller track (5) to be swivelled by 90 DEG , as may be seen from the figure. <IMAGE>

Abstract: A method for measuring the CT numbers of an in vivo tissues includes the steps of calculating a histogram of a region including the tissue, locating a leading edge of a peak within the histogram, substracting CT numbers assumed to result from background and intermixing of tissues, fitting the background-substracted peak to a gaussian distribution, and calculating the mode of the resulting peak. Whe the CT numbers of two different tissues having know densities are measured according to the method of the invention, the CT numbers may be used to obtain a standard for analyzing tissues of unknow density. The method can be implemented by means of a CT scanner, a computer, and appropriate software.

Title: Optical scanning device
IPC: G11B7/09
Filed: 1990-01-09
Granted: 1993-08-04
Abstract: Optical scanning device with an objective lens. In a recording and/or reproducing device which reads data from an optical record carrier, e.g. a disk, by the single-beam process, the entire optical scanning device is moved in order to direct the light beam onto the data tracks on the disk. Fine adjustment solely by moving the objective lens in the radial direction, as in the triple-beam process, is not possible, because the light spot follows the movement on the two-part photodetector, causing an offset in the track error signal TE. In order, nevertheless, to permit fine adjustment by means of the objective lens, the light beam (L) which scans the data is moved by a fine drive in a direction (W) which makes an angle  alpha  to the normal (R) to the data track. The light beam (L) is reflected from the disk onto a photodetector consisting of several photodiodes (A, B, C, D), and the track error signal TE is derived from the output signals (AS, BS, CS, DS) of said photodiodes by weighted sum and difference formation. Application: CD players, magneto-optical recording and reproducing devices, video disk players, DRAW disk players.
