Title: Demodulation method for receiver
Inventor: VISWANATHAN HARISH
IPC: H04Q7/36
Filed: 2000-07-12
Granted: 2007-07-10
Abstract: In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot. To this end, each time slot may have its own preamble that is mapped with a constellation mapping scheme which is a) known à priori, b) may be the same for all time slots, and c) may be different from the constellation mapping scheme used to encode user data in the time slot. A receiver can determine the constellation mapping used for each time slot from solely from the preamble of the time slot.

Abstract: L'invention concerne un désactivateur (16) comprenant un tube-canon (18) creux allongé dans lequel sont pratiquées une chambre interne cylindrique (20), une extrémité arrière fermée (26) et une extrémité avant ouverte (22), celle-ci étant fermée par un joint frangible (38). Un élément de canal (46) entoure partiellement une partie intermédiaire du tube-canon et y est fixé. Une paire de canaux (76, 78) de recul s'étendent de la chambre interne du tube-canon vers l'extérieur de manière radiale et vers l'arrière à travers le tube-canon et l'élément de canal et sont reliés à des cylindres de recul (52, 54) orientés vers l'arrière et dont les parties d'extrémité (60, 62) arrière ouvertes sont fermées par des joints (64, 66) frangibles arrière. Une cartouche (90) contenant une charge explosive (88) doit être insérée dans la chambre interne du tube-canon au niveau de son extrémité arrière. Le tube-canon, les canaux de recul et les cylindres de recul (52, 54) doivent, quant à eux, être remplis d'eau. Les joints frangibles (38, 64, 66) empêchent les fuites d'eau du désactivateur tant qu'il se trouve à proximité d'une bombe à désactiver. Un détonateur (36) est relié au désactivateur et plus spécifiquement à la cartouche pour faire exploser la charge explosive à distance. Après explosion de la charge explosive, une partie de l'eau est projetée et éjectée à une vitesse élevée hors de l'extrémité avant du tube-canon, rompant ainsi le joint avant frangible afin de perforer l'enveloppe extérieure de la bombe et désactiver les composants détonateurs internes de la bombe. Une autre partie de l'eau est redirigée à travers les canaux de recul latéraux et les cylindres de recul, rompant ainsi les joint frangibles arrière, pour être ensuite éjectée vers l'arrière hors du désactivateur. Le recul créé par la détonation de la charge explosive éjectant l'eau à travers l'extrémité avant du tube-canon est au moins partiellement contré par l'eau redirigée latéralement et vers l'arrière qui doit être éjectée vers l'arrière hors des cylindres de recul. Les cylindres de recul présentent au niveau de leur extrémité arrière (60, 64) des ailettes transversales (73, 74) en vue d'une dispersion à grand angle du jet fluide éjecté vers l'arrière.

Abstract: La présente invention concerne un système portable (20) de réchauffage de fluide intraveineux utilisant quatre circuits monolithiques intégrés de thermosondes (72, 74, 46, 78) pour les fonctions de surveillance et de régulation de la température. Ces sondes (72, 74, 46, 78) opèrent sur une série de plusieurs niveaux de façon à réduire la plage dynamique de l'étage final de réchauffage, ce qui assure une température de sortie plus précise et cohérente. Des transistors de puissance à effet de champ (104, 106, 108, 110) fournissent le courant d'attaque de chauffage à partir d'une source d'entrée courant continu non régulée (122). Une telle sonde (72, 74, 46, 78) est couplée à un microprocesseur (120) qui détermine en continu la température, réglant la puissance demandée aux transistors de puissance à effet de champ (104, 106, 108, 110) de façon à entretenir la température. Il est prévu une interface (40) desservant un éventuel afficheur numérique de mesure externe. Un coupe-circuit thermique en ligne (102) assure indépendamment une sécurité intégrée par mise à l'arrêt en cas de surchauffe.

Abstract: A method for applying hardfacing to teeth on a drill bit is disclosed. The method includes applying the hardfacing to at least one of the teeth so as to have a thickness selected to correspond to a position about exterior surface of the tooth. In one embodiment, the hardfacing thickness is increased near the crest of the tooth, and is decreased near the root of the tooth on at least one flank of the tooth. In one embodiment, the thickness is selected by controlling the powder flow rate in a plasma transferred arc welding system. In another embodiment an angle subtended by flanks of the tooth is selected to provide increased strength to the tooth, and the hardfacing is applied to the tooth to cause exterior surfaces of the hardfacing corresponding to the flanks to subtend an angle selected to provide increased penetration of the tooth through earth formations while drilling.

Abstract: A perovskite catalyst is prepared using a ceramic sol-sol methodology comprising preparing slurry in water of an alkaline earth metal salt, a powdered metal salt and a powdered transition metal oxide, adding a polymeric binder to form a paste, drying and comminuting the paste into a powder and heating the powder with a temperature profile to calcination temperatures. Preferably the slurry is formed of titanium oxide with barium carbonate and tin chloride in deionized water, and more specifically by a mixture according to Ba (1-0.05x) + TiO2 + SnCl2(0.05x) where x is in moles. The perovskite catalyst is preferably used in a process for oxidative coupling of methane. Catalyst performance is enhanced through the addition of halides to the feed gas in the reaction.
