Abstract: A user interface to a virtual camera for a 3-D rendering application provides various features. A rendering engine can continuously refine the image being displayed through the virtual camera, and the user interface can contain an element for indicating capture of the image as currently displayed, which causes saving of the currently displayed image. Autofocus (AF) and autoexposure (AE) reticles can allow selection of objects in a 3-D scene, from which an image will be rendered, for each of AE and AF. A focal distance can be determined by identifying a 3-D object visible at a pixel overlapped by the AF reticle, and a current viewpoint. The AF reticle can be hidden in response to a depth of field selector being set to infinite depth of field. The AF and AE reticles can be linked and unlinked, allowing different 3-D objects for each of AF and AE.

Abstract: An insurance product comprises a crop risk insurance policy component that insures against risk of loss for at least drought. An endorsement assembly is associated with the crop risk insurance policy component. The endorsement assembly comprises a grower compliance requirement, a right of payment, and ancillary terms and conditions. The grower compliance requirement requires a grower to comply with a qualified crop input plan for a particular crop in a field. The right of payment is contingent upon a first yield per unit land area of the particular in the field less than second yield per unit land area of a geographic area by more than a threshold amount. The geographic area covers a greater area than the field and is representative of at least one of the soil characteristics and the climate associated with the field. The right of payment is contingent upon compliance of the grower with the ancillary terms and conditions.

Abstract: A system and method for managing a crop insurance program facilitates determining an input management plan for application of a crop input to a field within a defined geographic area. A field yield is measured. The field yield pertains to a yield of particular crop associated with a field in a defined geographic area. An aggregate yield is estimated. The aggregate yield relates to the particular crop associated with the defined geographic area. The aggregate yield is scaled to represent a generally equivalent land area to the field. A difference or variation is determined between the field yield and the aggregate yield. The determined difference or indication thereof is made available to a receiving entity (e.g., insurer that is associated with at least one of claims and insurance on the crop in the field).

Abstract: A fan assembly for gas assembly engine is disclosed. The fan assembly includes a rotor that is coupled to at least one fan blade. The fan assembly also includes a spinner that extends towards the rotor and the fan blades so that an edge of the spinner engages the fan blades. The edge of the spinner thereby serves as a grounding element for the fan blade. If the spinner is fabricated from a composite or a plastic material that is not sufficiently conductive for grounding purposes, the edge may be coated with a conductive material. Alternatively, the spinner may be fabricated from a metallic material, which would eliminate the need for a conductive coating on the edge that engages the fan blades.
