Abstract: In a method for signalling a noise substitution when coding an audio signal, the time-domain audio signal is first transformed into the frequency domain to obtain spectral values. The spectral values are subsequently grouped together to form groups of spectral values. On the basis of a detection establishing whether a group of spectral values is a noisy group or not, a codebook is allocated to a non-noisy or tonal group by means of a codebook number for redundancy coding of the same. If a group is noisy, an additional codebook number which does not refer to a codebook is allocated to it in order to signal that this group is noisy and therefore does not have to be redundancy coded. By signalling noise substitution by means of a Huffman codebook number for noisy groups of spectral values, which are e.g. sections made up of scale factor bands which do not have to be redundancy coded, an opportunity is provided to indicate the presence of a noise substitution in a scale factor band in the bit stream syntax of the MPEG-2 Advanced Audio Coding (AAC) Standard without having to interfere with the basic coding structure and without having to meddle with the structure of the existing bit stream syntax.

Title: Method and apparatus for measuring quenchant properties of coolants
Inventor: BOURGEOIS THIERRY
IPC: G01N25/00
Filed: 1998-05-08
Granted: 2004-02-24
Abstract: A method of measuring the quenchability of a liquid coolant used to cool objects such as ingots produced by direct-chill casting. The method involves providing a sample of the liquid coolant; providing a probe for immersion in the sample, the probe having a temperature-sensing electrical device contained therein which generates an electrical response corresponding to temperature sensed; heating the probe in a gas, preferably by means of electrical resistance heating by a circuit which is electrically connected to the temperature-sensing electrical device, to a predetermined temperature measured by the electrical response of the temperature sensing device, immersing the probe into the sample and measuring the electrical response for a predetermined measurement period, and comparing the measured electrical response to a response of a reference liquid measured under equivalent conditions, to thereby determine the quenchability property of the liquid coolant. The invention also relates to apparatus for carrying out the method, as well as a method and apparatus for controlling the cooling of the object based on the measured quenchability of the coolant. In an alternative, the probe may be heated by means other than the electrical resistance heating at a rate of at least about 40 .degree. C/second.

Granted: 2004-01-06
Abstract: A pantagraph-type jack includes a pair of lower arms and a pair of upper arms. Upper ends of the lower arms and lower ends of the upper arms are connected to each other through first and second connecting shafts. An externally threaded rod is rotatably but axially non-movably supported on the first connecting shaft and threadedly engaged with a threaded bore provided in the second connecting shaft. In the pantagraph-type jack, the externally threaded rod is formed into a hollow shape, and external threads of the externally threaded rod are provided with a tapered portion formed in a convergent shape over a given light-loaded area from a tip end on the side of the second connecting shaft. Thus, a reduction in weight of the externally threaded rod can be provided, and the threaded engagement of the externally threaded rod with the threaded bore in the second connecting shaft can be conducted easily, which contributes to a reduction in weight and an enhancement in assemblability.

Abstract: In a telecommunications system, data having a higher sensitivity and data having a lower sensitivity are identified within a data set. The data having a higher sensitivity is encrypted to produce encrypted sensitive data.  Thereafter, the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The encrypted data set is then transferred from a sending unit to a receiving unit. Decryption information may be appended to the encrypted sensitive data before the data having a lower sensitivity and the encrypted sensitive data are encrypted to produce an encrypted data set. The decryption information may include an algorithm identifier, a key identifier, and receiver response instructions. At the receiving unit, the data set is decrypted to recover the data having lower sensitivity. A second decryption of the encrypted sensitive information recovers the data having a higher sensitivity. Appended decryption information may be used to locate and decrypt the encrypted sensitive information.

Abstract: L'invention concerne un catalyseur de purification de gaz d'échappement comprenant un support contenant du rutile de titane, une matière d'occlusion de NOx disposée sur un support comprenant au moins un élément sélectionné parmi un métal alcalin, un métal alcalino-terreux et des éléments des terres rares, et un métal noble disposé sur le support. Puisque le rutile de TiO2 et la matière d'occlusion de NOx forment un oxyde composite finement séparé, un poison du catalyseur peut être décomposé même lorsque la matière d'occlusion de NOx est empoisonné par du soufre, cette matière étant donc capable de récupérer facilement la capacité d'occlusion de NOx. Il est donc possible d'inhiber l'empoisonnement par soufre de la matière d'occlusion de NOx et de maintenir un taux élevé de purification de NOx même après une application à haute température.
