Abstract: L'invention concerne un neuro-stimulateur électrique utilisant des générateurs (10) d'impulsions produisant une fréquence mère, une fréquence porteuse, une première fréquence de modulation ainsi qu'une seconde fréquence de modulation. Une paire de multivibrateurs (16) et (18) produisent une sortie de train d'impulsions présentant un nombre réglable d'impulsions, par réglage de la fréquence porteuse, ce qui augmente également la puissance appliquée moyenne ainsi que le facteur de pénétration. Les oscillateurs maître et porteur du générateur d'impulsions fonctionnent de manière asynchrone, un mélangeur numérique (20) étant prévu afin de combiner ces fréquences. Par combinaison de filtres passe-haut et passe-bas (24) et (26), on donne à l'enveloppe de la forme d'onde du train d'impulsions une amplitude croissante à partir de sa valeur initiale pendant un intervalle prédéterminé. On a prévu un ensemble de transformateurs (T1) et (T2) d'impulsions conçus spécialement, afin de maintenir la configuration optimale de la forme d'onde d'impulsions, lorsque l'impédance des tissus change, ce qui assure une compensation via un composant réactif.

Title: Hydrocarbon processing of gas containing feed in a countercurrent moving catalyst bed.
Inventor: SMITH DAVID S
IPC: B01J8/12
Filed: 1990-07-17
Abstract: A uniform feed distribution system for selectively upgrading a feed stream of hydrocarbon fluid containing metallic components, such as organometallic components, and/or inert materials, which deactivate or contaminate catalyst particles counterflows into a descending bed of catalyst particles. The heated feed stream is at temperatures and pressures so that lighter hydrocarbon components or hydrogen evolve as gas components as it is introduced (14) into the reaction vessel. The evolved gas is separated into reservoir or pocket above a reservoir (30) of liquid components and both components are then uniformly and selectively introduced into the downflowing bed of catalyst. By forming a common supply volume of gaseous and liquid components, the gas components are independently accessible to the lower end of the moving bed of catalyst particles through an inclined distribution surface (10) preferably in the form of a cone. The cone is supported in the lower portion of the vessel to form a catalyst collection bin (24) for removal of spent catalyst from the bed. Gas distribution to the bottom of the inclined surface (10) is through a plurality of holes (32) formed at different elevations, but proportioned so that gas flow into the bed is substantially uniform, or a known pattern, independent of hole elevation or the elevation of liquid feed tubes (34) through the inclined surface (10).

The communication protocol of the bus system includes a plurality of commands such that when in the remote mode, the chip device determines the validity of each of the commands and provides an echo response message on the data bus in response to each of the commands except for a broadcast command. The remote modes of the chip device include a remote switch mode, a data input mode, a data output mode or a combination of the remote modes. The chip device is divided into six main functional areas: encoder/decoder, message analyzer, protocol sequencer, data storage, control timers, and input/output controller. The chip device may be used in small remote modules that are located in convenient locations adjacent to the loads they are controlling or switching. The remote modules are controlled by messages from a multiplex data bus controller which are formatted through the communications protocol of the data bus system. The chip device is designed to handle the communications protocol of the data bus system and provide interface between the data bus and other electronic hardware elements.

Abstract: An image compression system and method for compressing image data for transmission. Each block and corresponding sub-blocks of pixel data is subjected to a discrete cosine transform (DCT) operation. Varying levels of sub-blocks of resulting corresponding transform coefficients are selected for construction into a composite transform coefficient block corresponding to each input block of pixel data. The selection of transform coefficient block size for the composite block is determined by a comparison process between transform block and sub-block coding efficiency. The composite block is variable length coded to further reduce bit count in the compressed data.
