Abstract: Method for generating piecewise-affine multivariate functions, wherein the online computation of the search tree is performed in order to locate the input value in the polytopes of the partition, and the subsequent generation of the corresponding affine function. It also proposes a configurable and programmable device for generating piecewise-affine multivariate functions composed of an architecture with four functional blocks namely: a control unit block (1), a tree memory block, a parameter memory block and an arithmetic unit block; and it has at least three operating modes which can be selected using different values of a bus (config): writing of the tree memory, writing of the parameter memory and evaluating the affine function. It may include a fourth operating mode, which is the test mode.

Abstract: An apparatus for separating hot particles including a plurality of materials having different magnetic properties includes a plurality of permanent magnets arranged in a magnet assembly and configured to create a magnetic flux capable of providing a coercive force on at least a portion of the particles, the magnet assembly being mounted on a stationary shaft, a moving surface proximate the magnet assembly for carrying the particles in a downward path through the magnetic flux while the coercive force attracts the portion of the hot particles toward the moving surface, the moving surface being mounted on a drive shaft supported by a bearing, and an inert gas supply system which supplies inert gas into a gap between the stationary shaft and the drive shaft for cooling the drive shaft and the bearings, and into the magnet assembly for purging the magnet assembly of oxygen.

Abstract: A drive system for an apparatus separating hot particles being received by a moving surface includes a drive shaft for driving the moving surface receiving the hot particles, a drive unit for rotating the drive shaft, and a flexible coupling arranged between the drive shaft and the drive unit. The flexible coupling includes thin portions defining a portion of a heat transfer path from the drive shaft to the drive unit. The thin portions have large surface area to volume ratios for extending the heat transfer path. The thin portions dissipate heat when the flexible coupling is driven by the drive unit. A method for dissipating heat from a drive system for an apparatus for separating hot particles includes providing a flexible coupling and dissipating heat from the flexible coupling.

Abstract: The present invention describes compositions for disinfection and/or effective preservation of food, for example fresh food, which allows the effective removal of microorganisms from these. The disclosed compositions contain derived extracts from plants with antimicrobial activity, which can act on their own or in combination with other disinfecting agents such as organic acids and chlorine compounds. The compositions of the invention are able to remove microbial contamination, including pathogenic microorganisms in seeds and sprouts obtained therefrom without changing the germination properties and nutritional and/or alimentary properties of the sprouts.

Abstract: The procedure concerns placing into contact a lycopene source with a supercritical fluid under conditions that permit the solubilisation of lycopene in this supercritical fluid and to separate the lycopene concentrate by depressurisation of the supercritical fluid loaded with lycopene. When the depressurisation is carried out at pressures below 10 MPa, an oleoresin is obtained and when it is performed at pressures above this an extract is obtained, both of which are rich in lycopene free of organic solvents. The concentrate and the compositions it comprises have antioxidant properties and are useful for elaborating food products, cosmetics and pharmaceutical and nutraceutical products.

Abstract: It has one or more controls (1) that communicate with one or more receiving hosts (2, 3, 4) that govern the opening and closing of certain doors or accesses. Each control (1) has a single pushbutton (5), in which according to the number, duration of the presses and/or distances between the control (1) and the hosts (2, 3, 4), said remote control (1) can control and be controlled with respect to any number of hosts (2, 3, 4), according to pre-established modes. Communication between the remote controls (1) and the hosts (2, 3, 4) is bi-directional and includes a secret code by means of an algorithm (RPDA) specifically developed for the system which consists of a pre-coded preamble that heads all the communication messages and requires a satisfactory response at the end of the flow of messages.
