Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A method of determining usable area of a structure for solar energy production may include obtaining a three-dimensional model of a structure and obstructions associated therewith, and performing a shading analysis using the obtained three-dimensional model to obtain a usable area of the structure. A method of providing solar information for a structure using a Web portal may include providing an interactive map, receiving a user selection of a structure located on the interactive map, and providing solar information for the selected structure, wherein the solar information is based at least in part on a usable area obtained by performing a shading analysis using a three-dimensional model of the structure and obstructions associated therewith. A system for providing an interactive Web portal may include a database including solar information regarding a structure, and a server configured to access the database to retrieve the solar information and provide the Web portal.
