Abstract: Mechanisms are disclosed for modelling and quantitatively characterizing emissions inflows and outflows. Scoping inputs are received including a physical process defined scope of emission-producing physical inputs. Modeling inputs are received, including footprints associated with physical manufacturing inputs. The model energy flows may be provided via a graphical modeling user interface and support allocation rule definitions for distributing emissions footprint definitions. An estimated emission flow is calculated based on combined energy flows. The material flows may be derived from aggregated transaction data associated with emission-producing physical inputs. The calculated emission flow may be based on a calculated emission footprint at stages along a production process. Analytics user interfaces associated with the calculated emissions flows may provide insight into the highest emission producing emission drivers along the production chain in connection with a technical report.

Abstract: An optical assembly for a surgical microscope includes an iris diaphragm assembly arranged in a first plane and including a first adjustable diaphragm arranged in a first observation beam path of the surgical microscope and defining a first opening, and a second adjustable diaphragm arranged in a second observation beam path of the surgical microscope and defining a second opening, an optical wheel rotatably mounted on the iris diaphragm assembly in a second plane, the optical wheel including openings for receiving optical elements and optical element holders fastened to the optical wheel to secure the optical elements in the openings without creating transverse forces on the optical elements, the optical wheel having substantially a shape of a half wheel and including an external gearing provided on a circular portion of the optical wheel. A surgical microscope includes the optical assembly with the iris diaphragm assembly and the optical wheel.
