Publication number: 20190236785Abstract: A method for determining virtual articulation from dental scans. The method includes receiving digital 3D models of a person's maxillary and mandibular arches, and digital 3D models of a plurality of different bite poses of the arches. The digital 3D models of the maxillary and mandibular arches are registered with the bite poses to generate transforms defining spatial relationships between the arches for the bite poses. Based upon the digital 3D models and transforms, the method computes a pure rotation axis representation for each bite pose of the mandibular arch with respect to the maxillary arch. The virtual articulation can be used in making restorations or for diagnostic purposes.Type: ApplicationFiled: April 10, 2019Publication date: August 1, 2019Inventors: Alberto Alvarez, Eric S.

Patent number: 10279883Abstract: An energy efficient and lighter-than-air high altitude platform (HAP) is disclosed that allows for sustained station keeping at high altitudes of about 50,000-80,000 feet for prolonged periods of time. The HAP includes an aerodynamically streamlined body that may have the topology of a torus. The body may be inflated with a lighter-than-air gas in an amount sufficient to provide lift to the high altitudes. The HAP has a duct extending through the pressurized body that diverts flow through the duct and reduces aerodynamic drag. The HAP may include one or more propellers situated in the duct to provide propulsion and maintain a given location of the HAP relative to ground. There may also be a control system, a solar energy collection system, an energy storage system, and/or any of a variety of payloads to accomplish various tasks, such as communication and/or situational awareness applications.Type: GrantFiled: May 17, 2016Date of Patent: May 7, 2019Assignee: General AtomicsInventors: John Abele Parmentola, John Marshall Rawls, Alberto Alvarez-Calderon F., Brian Maskew
