Abstract: An obstacle avoidance system for a stabilized aerial vehicle and a method of controlling same are provided. Using low angular resolution obstacle proximity data, such as from low angular resolution obstacle detection sensors, when a determination is made that an operator command to a vehicle propulsion system will result in a collision, the system overrides the operator command and substitutes an avoidance speed command and avoidance heading, while maintaining operator situational awareness, in a manner that is transparent to the operator. In an implementation, examination of objects requires the obstacle avoidance system to allow the vehicle to get close to obstacles. A human-portable aerial vehicle according to an implementation can be used for building surveillance, route inspection, surveillance of windows/hallways/rooftops, power distribution towers, pipelines, bridges, buildings or close examination of suspect objects.

Abstract: The invention relates to azeotropic and azeotrope-like mixtures of HFC-32, HCl, and Cl2, and processes for separating the azeotrope-like mixtures of HFC-32 and HCL and HFC-32, HCL and Cl2.

Abstract: The present disclosure provides methods of using unsealed and non-colloidal radiopharmaceuticals, for example beta emitting radiopharmaceuticals such as Yttrium-90 chloride, Indium-111 chloride, F-18-2-deoxy-2-fluoro-D-glucose, or combinations thereof, for locoregional ablation of cells in the abnormal tissue.

Abstract: The invention relates to azeotropic and azeotrope-like mixtures of HFC-32 and HCl or a mixture of HCl and Cl2, and a process for separating the azeotrope-like mixtures.

Abstract: Disclosed are improved fluorination processes and fluorine-containing compositions which involve introducing to one or more fluorination process compositions a water reactive agent in an amount and under conditions effective to decrease the amount of water in that composition. The water reactive agent is preferably introduced to the fluorination reaction process at a location proximate to the site of the fluorination reaction, or upstream of the fluorination reaction, in amounts and under conditions effective to produce a relatively lower concentration of water in the composition, and preferably throughout the fluorination process.
