Title: Procede et dispositif de mesure d'une substance particulaire et appareil compose de plusieurs de ces dispositifs
Inventor: OLSSON BERT-AKE
IPC: G01F11/10
Filed: 1997-08-14
Granted: 2005-05-10
Abstract: La présente invention concerne un procédé et un dispositif de mesure d'une quantité prédéterminée de substance particulaire. L'invention concerne également un appareil de mesure incluant au moins deux de ces dispositifs de mesure. Le dispositif de mesure est constitué d'un corps (2), d'un conduit d'amenée, d'un conduit de déchargement, et d'un réservoir (30). Le corps (2) définit une chambre de mesure (20). Le conduit d'amenée, qui est ininterrompu, comporte un orifice d'admission (6), et mène à la chambre de mesure (20). Ce conduit d'amenée est capable de rotation autour d'un axe (4) incliné selon un angle  alpha  par rapport à la verticale (V), de façon qu'une partie au moins du conduit d'amenée soit inclinée vers le bas pour le remplissage et vers le haut pour le déchargement. En fonctionnement, le conduit d'amenée permet l'écoulement par gravité de la substance particulaire dans la chambre de mesure (20), et bloque par gravité l'entrée de substance particulaire dans la chambre de mesure (20) pendant le déchargement. Le conduit de déchargement comporte un dispositif de blocage qui interdit la sortie de substance particulaire depuis la chambre de mesure (20) pendant le chargement, mais autorise la sortie de substance particulaire depuis la chambre de mesure (20) pendant le déchargement. Le réservoir (30) est raccordé au conduit d'amenée de façon à pouvoir accompagner sa rotation pendant le fonctionnement. Par conception, lorsque le réservoir contient un volume quelconque de substance particulaire, la rotation de ce réservoir confère à la substance particulaire un mouvement au niveau de l'orifice d'admission (6), lequel mouvement permet à la substance particulaire de s'écouler dans la chambre de mesure (20).

Abstract: A method of restricting file access is disclosed wherein a set of file write access commands are determined from data stored within a storage medium. The set of file write access commands are for the entire storage medium. Any matching file write access command provided to the file system for that storage medium results in an error message. Other file write access commands are, however, passed onto a device driver for the storage medium and are implemented. In this way commands such as file delete and file overwrite can be disabled for an entire storage medium.
Patent CA-2272806-C (CA)
Inventor: HASCHBERGER PETER
IPC: G01N21/35

Abstract: The correction method of the invention synthesizes a distortion-free interferogram (or spectrum) from a measured interferogram, which has been distorted by detector non-linearities, and a finite series of orthogonal functions derived therefrom. The coefficients of the series of functions are selected with a priori knowledge about the limited spectral sensitivity of the radiation detector, preferably with the method of Gaussian least squares fit of observation, such that the resulting spectrum assumes the value of zero of the distortion-free spectrum outside of the sensitivity range, and in freely-definable ranges. The method of the invention can be used to correct detector non-linearities, as occur in Fourier spectroscopy.

Abstract: A roof vent comprises two parts, a cover and a conduit. The conduit, with a pipeline already attached, can be easily connected to the cover, after the cover has been installed on a roof. The conduit will plug into the cover making installation easy. The vent includes a channel or moat which surrounds the outlet of the conduit. Thus, if during extreme weather conditions, moisture passes into the cover from outside through its opening and if it gets past the door flap, it will be trapped in the channel.

Abstract: The invention concerns a method for sorting an acoustic signal (S) or a spectral line (F) of maximal energy E, transmitted by a "target", capable of being immersed in the sea, among a multitude of acoustic signals coming from particular noise generators (W), radiating acoustic signals of similar type and of energy higher than energy E, using: a set of N acoustic sensors, identically parametrized in standby mode, capable of being immersed, for detecting the presence of a signal (S) or a desired spectral line (F), the set of N sensors defining a particular number of standby cells to two adjacent sensors, each sensor being associated with one or several detection/target domains, which are defined as the geographical zones inside which the presence of the "target" is known to be detectable and outside which the "target" is known to be undetectable.; a maximum number Nmax of sensors concerning one or several "set" zone(s) (selected among a set of elementary geographical zones) of a common standby cell and capable of simultaneously detecting the "target". The invention is characterised in that the acoustic signal (S) or the line (F) is detected by a number Nd of acoustic sensors in the set of N sensors, and analysed by a series of steps whereof the main ones comprise the definition of the noise generator (W) locating conditions and the determination relative to the set zones.

Abstract: A shelf divider adapted for mounting within shelf spaces of differing heights generally includes a divider member defining a series of edges. Engagement tabs extend from the edges, and include a first pair of tabs on one edge and a second pair of tabs on another edge. A stabilizing tab extends from an edge opposite the first pair of tabs, and a stabilizing tab also extends from an edge opposite the second pair of tabs. Each shelf member includes a row of slots in an upper support wall, and also includes a row of slots in a lower, downwardly facing wall. The shelf divider is dimensioned and configured such that it can be positioned in a first orientation and engaged within a shelf space having a first height, by engaging the first pair of tabs with slots in the lower shelf member and engaging the oppositely-located stabilizing tab within the downwardly facing slot in the shelf member thereabove. The same shelf divider can also be used to divide a shelf space having a different height by positioning the shelf divider in a second orientation in which the second pair of tabs are received within the slots in the lower shelf member of the second shelf space. The oppositely-extending stabilizing tab is received within the downwardly facing slot in the shelf member located thereabove for stabilizing the shelf divider against lateral forces.

Title: Optimized synchronization preamble structure
Inventor: BOHNKE RALF
IPC: H04L7/00
Filed: 2000-04-14
Granted: 2011-11-29
Abstract: The invention is based on the synchronization and training preambles. The optimizes sequence is very suitable to generate a preamble or a part (also called field) of it by mapping the sequence to the appropriate subcarriers of a OFDM symbol with a FFT size of 64. The benefit of the invention is the improved timing accuracy when the autocorrelation result in the B-FIELD is used for synchronization. The time domain structures of the preambles according to the prior art are not changed according to the invention. The advantages of the present invention can be summarized as follows: The invention proposes an OFDM based synchronization symbol with a low peak-to-average-power-ratio and a small dynamic range, - the synchronization performance (timing accuracy compared to current preambles) is improved, - the specified time domain preamble structures according to the prior art are not modified, and - no extra complexity is needed.
