20080252988	Method of Fabricating Tridimensional Micro- and Nanostructures as Well as Optical Element Assembly Having a Tridimensional Convex Structure Obtained by the Method - A method is for forming three-dimensional micro- and nanostructures, based on the structuring of a body of material by a mould having an impression area which reproduces the three-dimensional structure in negative form. This method includes providing a mould having a substrate of a material which can undergo isotropic chemical etching, in which the impression area is to be formed. An etching pattern is defined on (in) the substrate, having etching areas having zero-, uni- or bidimensional extension, which can be reached by an etching agent. A process of isotropic chemical etching of the substrate from the etching areas is carried out for a corresponding predetermined time, so as to produce cavities which in combination make up the impression area. The method is advantageously used in the fabrication of sets of microlenses with a convex three-dimensional structure, of the refractive or hybrid refractive/diffractive type, for forming images on different focal planes.	10-16-2008

20100088160	Automatic Learning for Mapping Spoken/Text Descriptions of Products onto Available Products - A method, processing device, and machine-readable medium are provided. Costs of states of a state space are calculated. Each state represent one or more available product attributes having zero or more decided attribute values. The calculating is based, at least in part, on training data associated with previously requested and offered products. Determining a next state such that one or more products are available and a sum of values, including a cost of a next state and a cost of a perturbation of one of the one or more requested product attribute values to reach the next state is a minimum value. A value for a product attribute is mapped according to the minimum sum of values and product attribute values of available products.	04-08-2010
