Abstract: A device for concentrating solar radiation (4) with longitudinal mirrors (7) and a longitudinal receiver (1), has mirrors with a circular cross-section with a radius of curvature that is twice the transverse distance from the center (35) of each mirror to the central point (3) of the receiver. The width of the receiver is 1% of the transverse distance from the central point to the center (89) of the furthest mirror (32). The width of each mirror is determined according to the drift of the rays reflected when the mirror focuses the sun, prescribing an equal width for all mirrors, which is: equal to the width of the active face (2) of the receiver when mounted according to the meridian; and triple the width of the active face (2) of the receiver when mounted according to the parallel of latitude. The mirrors are installed in a contiguous manner and the receiver is installed at a height on columns (8).

Abstract: A novel document security and authentication system is based on a transparent element on which more than one image appears depending on the manner in which the element is viewed. The system is based on cells or sheets of liquid crystal doped with one or more dichroic dyes. The images obtained with the aid of a polarizer can be printed onto a very thin (?m or 10 tens of a ?m) sheet of polymer material; the images may also be in greyscale or in color. There is no need to apply electrical signals during the production or use thereof.

Abstract: A continuous query parallel engine on data streams provides scalability and increases the throughput by the addition of new nodes. The parallel processing can be applied to data stream processing and complex events processing. The continuous query parallel engine receives the query to be deployed and splits the original query into subqueries, obtaining at least one subquery; each subquery is executed in at least in one node. Tuples produced by each operator of each subquery are labeled with timestamps. A load balancer is interposed at the output of each node that executes each one of the instances of the source subquery and an input merger is interposed in each node that executes each one of the instances of a destination subquery. After checks are performed, further load balancers or input managers may be added.

Abstract: The invention relates to a method for measuring the forces and the moments generated by the tire-road contact from the combination of unit deformation or strain signals measured in different angular and radial positions of the wheel. The angular positions in which the sensors are placed are those permitted by the geometry of the tire. The combination of deformation signals results in six or more signals that are independent of the angular position of the measuring sensors with respect to the tire-road contact point. The effect of temperature and loads that generate deformation signals that do not depend on said angular position of the measuring points, such as centrifugal forces, have been eliminated from the aforementioned signals. Said signals provide estimates of the loads by means of the resolution of two systems of linear equations with constant matrices and three unknowns each.

Abstract: A method carried out by a controller is disclosed. The method includes receiving (s10) a message including a request token. A request token is a value used by a consumer (300) to request authorization from a user to access protected resources from a service provider (400). A service provider (400) is at least one of a software application and web site that is configured to provide access to protected resources. A consumer {300} is at least one of a software application and a web site that is configured to access a service provider (400) on behalf of a user. The method further includes determining (s20) whether the message meets policy settings governing the access to protected resources; and, if it is determined (s30) that the message does not meet the policy settings, preventing (s34) the request token from being forwarded to the service provider (400) associated with the request token.

Abstract: A receiver for a solar power plant with mirrors (7) and horizontal longitudinal receivers (1) includes a rotating shaft and axis of symmetry which (14) are parallel to a longitudinal axis of the radiation receiver. The receiver is formed by a balanced expansion and pressure collector, the tubes (19) of which are grouped in a separate central bundle (20) and adjacent bundles (21 and 22), thermally insulated from one another longitudinally. Heat transfer fluid circulates first through both adjacent bundles in parallel, to then be injected into the central bundle, where the radiation intensity received is greater because of receiving the radiation from the array of mirrors focused on the midline of the active face (2) of the receiver, each bundle of tubes being able to be covered by a separate (60, 61, 62) transparent window (28).

The photobioreactor enables supplying the gases to the culture from inside the chamber. It provides highly efficient algae illumination, allows easy exchange of CO2 from the emission gases to the culture and can be used at a low cost on a large scale.

Abstract: A high throughput reactor for the mass production of wafers through chemical vapor deposition, mainly to form silicon epitaxies for the photovoltaic industry, is described. Main innovation is a high susceptor stacking density: several graphite susceptors are placed vertically and parallel to one another, electrically interconnected, and are heated by Joule effect. Electrical current gets to the susceptors from the current source through specially designed feedthroughs, which connect the cold room outside the deposition chamber with the hot susceptors. Gas flows vertically between susceptors. The substrates on which deposition occurs are placed on the susceptors. Below the susceptors a pre-chamber is found, in which entering gas calms down and distributes homogeneously. Susceptors and pre-chamber are placed inside a stainless steel chamber, which is internally covered by a reflecting material, and externally kept cold by water.
