Abstract: An application applying mixed use of conventional hydrocarbon fuel with renewable energy sources for hydrogen production presents an optimal balance between economics and environmental benefits for any long-range implementations. A hydrogen production system incorporates the use of electricity from renewable sources in hydrogen reforming plants for various functions to achieve better environmental performance. The hydrogen production system includes the compression of hydrogen for high-pressure storage and an electrical heating supply for an endothermic reforming process of producing hydrogen from an input fuel. The compressed hydrogen, produced using renewable energy sources, also provides a means of stored mechanical energy. Another hydrogen production system utilizes a conventional chemical reforming process to provide leveled hydrogen generation together with electrolysis from the fluctuating renewable energy sources, which also provides low cost hydrogen generation, good environmental performance and commercial dependability.

Abstract: An apparatus is provided for correcting spinal abnormalities, and particularly for providing compression and/or distraction of vertebrae without additional tools or instrumentation. A, plate member (20) is provided with a plurality of slots (30,32), one of which has a sloped internal edge or surface (50). The plate is anchored to one vertebra by a first anchor (22), and a second anchor (24) is then placed through the slot with the sloped internal edge or surface and tightened. Such tightening causes the plate to move with respect to the tightened anchor, and thus to transmit compression or distraction to the vertebrae. The apparatus is particularly useful in minimally-invasive surgeries but can also be used in more traditional open surgeries.

Title: Estimation of background noise and its effect on sonar range estimation
Inventor: NERETTI NICOLA
IPC: G01S/
Filed: 2004-06-08
Abstract: A system (100) and method for estimating the signal-to-noise ratio (SNR) in a sonar environment and for determining the effect of the estimated SNR on sonar ranging accuracy. The system includes a sensor (102), a transmitter (103), a receiver (104), a plurality of band-pass filters (106), a cross correlator (108), and a data analyzer (110). The transmitter (103) transmits a pulse through a transmission medium. The sensor (102) senses an echo returning from a selected target (112), and provides a signal representing the echo to the receiver (104), which in turn provides an indication of the echo to the band-pass filters (106). The filters (106) provide filtered versions of the echo and pulse to the cross correlator (108), which performs cross correlation operations on filtered echo and pulse. By analyzing the cross correlator output data, the system (100) can determine peak variability within multiple frequency sub-bands, thereby allowing more accurate SNR estimations in noisy environments.

Title: Simple matrix addressing in a display
Inventor: DERICHS KEVIN
IPC: G01F1/64
Filed: 2004-11-09
Abstract: An addressing mechanism for charging and discharging quasi-capacitive elements in an X-Y matrix. The addressing mechanism may be configured to toggle a resistor-capacitive time constant between large and small values such as by opening or closing a circuit path to a low impedance resistor (logic bits 0) disposed in parallel with a higher impedance in-line resistor (logic bits 1).  When this occurs, elements in the X-Y matrix (102) can be addressed and controlled. The X-Y matrix may be comprised of multiple "rows" and "columns"  of conductors where crosstalk may occur along the columns and rows (100 and 101). Crosstalk may be curtailed by using either hysteresis management or global control of the row's impedance along its entire length. The resulting control obviates the need for active devices at each matrix element to perform the switching functions.

Abstract: L'invention concerne un pneu comprenant un élément piézoélectrique à flexion (313), associé à un dispositif de stockage d'énergie (p. ex. un condensateur). Cet élément piézoélectrique à flexion est monté en porte à faux dans un logement (311), de façon à être positionné sensiblement le long d'un plan orthogonal à un sens radial (E) dudit pneu et de sorte qu'une première extrémité (315) de l'élément piézoélectrique est serrée contre le logement. Une masse de charge (312) est couplée à la seconde extrémité (316) de l'élément piézoélectrique à flexion. Un petit espace (314) est formé entre les parois intérieures du logement et la surface extérieure de la masse de charge, afin de permettre une flexion limitée dudit élément piézoélectrique. Ce logement, renfermant l'élément piézoélectrique, est monté dans une partie de pneu en correspondance avec une zone de bande de roulement du pneu, de préférence sur la surface intérieure du pneu. Cet élément piézoélectrique fléchit sous l'effet de l'accélération radiale lorsque le pneu est en rotation. La masse de charge et l'espace sont dimensionnés pour permettre l'obtention : a) de petites oscillations de l'élément à flexion sensiblement pendant un tour complet du pneu, lorsque le pneu tourne à faible vitesse, et b) de grandes oscillations de l'élément à flexion sensiblement seulement pendant le passage de la section du pneu, renfermant l'élément piézoélectrique, dans l'aire de contact. Une puissance électrique suffisante pour l'alimentation électrique d'un dispositif électronique intégré dans le pneu est obtenue, tout comme une longue durabilité de l'élément piézoélectrique.
