Abstract: A non-transitory computer readable medium for storing one or more sequences of one or more instructions for execution by one or more processors in a processing system to perform a method for determining a dichotomy for a parametric decision process, the instructions when executed by the one or more processors are presented. Embodiments can be configured to define a network having a plurality of members as inter-member coherency coupling represented by elements of a coherency matrix, wherein for each ith member the network includes an intensity value, Ii. Further embodiments may include determining non-diagonal elements Tij of the coherency matrix in which i?j and in which i and j represent ith and jth members of the network, and constructing diagonal kernels Ki or non-diagonal kernels Hi based on the non-diagonal elements Tij of the coherency matrix and intensity values (Ii) of the members.

Abstract: There is disclosed an expanded beam fiber to fiber connector, based on non-imaging optic principles for coupling light beams from one optical fiber to another. The system consists of two identical connector parts, referred to herein as a collimating part and a concentrating part, each having a preferred partially curved reflective boundary surface for minimizing power loss and surrounding either a hollow space or a space filled with a uniform transparent medium. In one embodiment the boundary is metallic while in a second embodiment the boundary is in the form of an interface allowing total internal reflection. In both the hollow and filled case a lens may be located at the expanded end of both the collimater part and the concentrator part forming the connector. The connector is preferably located in a housing in order to protect and preserve the mechanical stability of the coupler.
