Patent CA-2221969-A1 (CA)
Inventor: KNIGHT JERRY EUGENE
IPC: H04B1/709
Filed: 1996-05-24
Abstract: L'invention a pour objet une technique pour minimiser ou supprimer l'effet des signaux à trajets multiples dans des signaux de code de bruit pseudo-aléatoire lors du traitement par le récepteur, tel qu'un récepteur d'un système GPS. La présence de signaux à trajets multiples affecte négativement les mesures des codes et les mesures de phases porteuses des signaux de code de bruit pseudoaléatoire. Selon un aspect de l'invention, il est possible d'améliorer la poursuite du code en présence de signaux à trajets multiples, en échantillonant le code reçu par une fenêtre d'atténuation des effets des trajets multiples (figure 25D), ce qui permet d'obtenir une fonction d'erreur de code (figure 25F) qui réduit ou supprime les effets des trajets multiples. La fenêtre d'atténuation des effets des trajets multiples, qui peut présenter n'importe laquelle parmi un nombre de formes d'ondes préférées (figures 35B35E), fournit une fonction d'erreur de code qui varie dans des sens opposés à partir de zéro au niveau d'un point de poursuite requis (402) mais adopte une valeur proche de zéro lorsque l'on fait avancer la fenêtre depuis le point de poursuite ou de synchronisation selon plus d'une petite fraction d'une puce de code. Du fait de cette valeur d'erreur de code proche de zéro au début du point de poursuite requis, des signaux à trajets multiples temporisés vont présenter une fonction d'erreur de code correspondante qui est proche de zéro (figure 25F) au niveau du point de poursuite requis des signaux directement reçus, et les signaux à trajets multiples vont, par conséquent, avoir peu ou pas d'effet sur le point de poursuite requis et sur la synchronisation du code. Les effets des signaux à trajets multiples sur les mesures des phases porteuses sont minimisés par échantillonnage des signaux reçus, avec leurs éventuelles composantes de trajets multiples, avant et immédiatement après les transitions de codes (vecteurs A et B, respectivement). La relation vectorielle des signaux à trajets multiples (M) et des signaux (D) directement reçus est telle que la réalisation d'une moyenne vectorielle de deux types d'échantillons (A et B) produit le signal directement reçu (D) et sa phase correcte, tandis qu'un grand nombre, voire même la totalité, des composantes (M) des trajets multiples sont supprimées.

Title: Signal coding system
Inventor: OZAWA KAZUNORI
IPC: G10L25/27
Filed: 1998-04-02
Abstract: For voice and musical signal, a signal coding system which can obtain good sound quality even at a low bit rate is disclosed.      The signal coding system predicts an input signal in a predicting circuit and performs orthogonal transformation in a first orthogonal transformation circuit of a predicted residual error signal. In a coefficient calculating circuit, a coefficient of a smaller degree is calculated for expressing an envelope of the orthogonal transformation coefficient in the orthogonal transformation circuit. In a quantization circuit, quantization is performed by expressing the orthogonal transformation coefficient with a plurality of pulse trains with determining positions for generating a pulse using the output of the coefficient calculating circuit. The envelope of the orthogonal transformation coefficient is expressed by the coefficient with smaller degree. On the basis of the coefficient, the orthogonal transformation coefficient is expressed by a plurality of pulse trains to perform more efficient coding than that of the prior art.

Title: Method and arrangement for removing deposits in and on feed nozzles or feed pipes of firing installations
Inventor: SPICHAL PETER
IPC: F23J3/00
Filed: 1998-04-14
Abstract: In order to remove deposits in feed nozzles (20), which serve to recycle exhaust gas into the furnace of a firing installation, a lance (27) can be inserted into the feed nozzles (20) and is held in such a way as to be displaceable in its longitudinal direction. The lance (27) has a nozzle head (28) at its front end for the spraying of water and is connected at its rear end to a valve device (29), which can be adjusted via a control device (32) with regard to the water quantity, the water pressure and the opening and closing times. By means of the lance (27), water is sprayed in a finely distributed manner onto deposits (34) in the interior of the feed nozzle (20), as a result of which the water penetrates into these deposits and causes these deposits to be blasted off due to the development of vapour.

Abstract: The Pharmacap consists of an opening and closeable locking lid for pill containers used in the Pharmaceutical field. The Pharmacap's design consists of two sections. The rim of the upper section sits flush on the lip of the pill container; it has a seam dividing its top in half. The front half with its extending lip flips up when the back half is pushed down upon. This is possible due to the fulcrum located underneath, providing a leverage point. This upper section is held to the container by the lower section, which is shaped like a moveable "O" ring with a small notch cut out. When the "O" ring is rotated and its missing notch aligns with the upper section's extended lip, the front half can then flip up. If the notch doesn't line up with the extended lip, the top section's front half will not flip up.
