Abstract: A multimode optical waveguide network comprises a parent waveguide and a plurality of child waveguides. Each waveguide is a multimode optical waveguide having a first surface region, multiple second surface regions, and at least one guiding element attached to a surface of the waveguide or embedded within the waveguide, each second surface region of the parent waveguide optically coupled to the first surface region of a corresponding child waveguide. The guiding element(s) of the parent waveguide is arranged to guide a beam, from or to its first surface region, to or from any selected second surface region of its multiple second surface regions. The guiding element(s) of each of the waveguides is configurable for selecting the second surface region of that waveguide and/or responsive to at least one beam characteristic for selecting the second surface region of that waveguide via modulation of the at least one beam characteristic.

Abstract: A noninvasive patient-specific method is provided to aid in the analysis, diagnosis, prediction or treatment of hemodynamics of the cardiovascular system of a patient. Coronary blood flow and pressure can be predicted using a 3-D patient image-based model that is implicitly coupled with a model of at least a portion of the remaining cardiovascular system. The 3-D patient image-based model includes at least a portion of the thoracic aorta and epicardial coronaries of the patient. The shape of one or more velocity profiles at the interface of the models is enforced to control complex flow features of recirculating or retrograde flow thereby minimizing model instabilities and resulting in patient-specific predictions of coronary flow rate and pressure. The invention allows for patient-specific predictions of the effect of different or varying physiological states and hemodynamic benefits of coronary medical interventions, percutaneous coronary interventions and surgical therapies.

Abstract: An adapter assembly includes a single-piece or two-piece multi-fiber adapter defining a recess at which a contact assembly is disposed. The adapter assemblies can be disposed within adapter block assemblies or cassettes, which can be mounted to moveable trays. Both ports of the adapters disposed within adapter block assemblies are accessible. Only one port of each adapter disposed within the cassettes are accessible. Circuit boards can be mounted within the block assemblies or cassettes to provide communication between the contact assemblies and a data network.

Abstract: A method and apparatus for differentiating between authentic and counterfeit item, and legacy additive manufactured (A.M) components securely throughout the lifecycle using grating interferometry, blockchain, and smart contracts. The method includes fabrication of a trust anchor by laser power modulation to selectively create porosity which can encode digital information within the component using programmable invisible ink (PGII). X-ray interferometry reads out the digital information as well as texture unique to the component. A quick response (QR) code is implemented with other anti-counterfeiting features to increase efficiency. A smart contract between X-ray interferometry radiography instruments and a blockchain database establishes item provenance. The characteristics of PGII are compatible with additive manufacturing, as well as other manufacturing processes such as injection molding and casting.
