| 20120119960 | Waveguide radiating element of an antenna suitable to operate in the Wi-Fi band, and system for measuring the performances of an antenna operating in the C band and using such a radiating element - Structures and methods for a tunable waveguide radiating element are disclosed. The waveguide radiating element comprises a rectangular tube, which includes partially filled dielectric slabs that are disposed on parallel planes and incident on a lower edge of the element's mouth. The faces of each slab are engraved with a number of concentric SRR squares that present a gap on one of its sides. The distance between any two consecutive slabs may vary. The gaps of the outmost square may be arranged in such a way that, on the facing sides of two adjacent slabs, the gaps are rotated with respect to each other. | 05-17-2012 |
| 20120033278 | Optical Logic Gate - Optical logic gate having a second-harmonic generator element that receives a first and a second optical input signal respectively having a first and a second angular frequency and respectively having a first and a second polarization, and which provides a second-harmonic optical signal having a third angular frequency and a third polarization. The third angular frequency is equal to the sum of the first and the second angular frequency. The third polarization is a function of the first and the second polarization. The second-harmonic generator element includes a second-harmonic generator layer in a material having a non-null second-order optical tensor. | 02-09-2012 |

| 20110270644 | SYSTEM AND METHOD TO ESTIMATE THE EFFECTS OF RISKS ON THE TIME PROGRESSION OF PROJECTS - An apparatus (computer coupled to risk and planning data repositories) and method are provided which, upon finding well in advance possible delays of time references of end task or key milestone of a project (or interdependent projects) in life cycle, due to potential risks, calculate and output a set of values (coefficients matrix). These coefficients represent a two-way link between each risk and each milestone and their values estimate the contribution of a specific risk to a specific task/milestone. For each risk, it is possible to highlight the contribution of such risk to possible shift of the whole set of project tasks/milestones; at the same time, for each project task/milestone, the coefficients highlight the contribution of the whole set of risks to the time shift of such milestone/task. The coefficients values address more effectively reduction actions of the possible project/tasks delays. Similar results pare achieved for multi-interdependent-projects. | 11-03-2011 |
