Abstract: Described herein are methods and systems for detecting and correcting errors when picking up and lowering a payload coupled to a tether of a winch system arranged on an unmanned aerial vehicle (UAV). For example, the winch system may include a motor for winding and unwinding the tether from a spool, and the UAV's control system may control the motor to lower the tether and monitor an electric current supplied to the motor to determine whether a payload has detached from the tether. This process of lowering the tether and monitoring the motor current may be repeated up to a predetermined number of times, at which point the control system may operate the motor to detach the tether from the spool, leaving both the tether and the payload behind.

Abstract: Nowadays, one of the major problems of the oil industry is the presence of large amounts of water and salts, which cannot be efficiently removed by conventional dehydrating polymers. In addition, the acid stimulation operations of petroleum wells cause the chemical degradation of demulsifiers such as polyethers and phenolic resins, reducing drastically their efficiency as water and salt removers. Based on aforementioned, a series of new copolymers has been developed; these copolymers are combinations of an acrylic and an aminoacrylic monomer and they are synthesized by semi-continuous emulsion polymerization (under starved feed conditions), which ensures both the homogeneity of the different chains as well as the randomness of the monomers distribution. The solutions of one of these random copolymers have shown an efficiency similar or superior to combinations of two or three block copolymers (formulations), when they are applied in light or heavy crude oils.

Abstract: A method for indicating property inheritance in object hierarchies is disclosed. In one embodiment, such a method includes enabling a user to select an object in an object hierarchy. In response, the method displays a property sheet showing property values for the selected object. The property sheet shows a property value that is inherited from an object upstream from the selected object. The method provides, on the property sheet, an icon indicating a level in the object hierarchy from which the property value is inherited, and a label indicating a source object in the object hierarchy from which the property value is inherited. The label may, in certain embodiments, incorporate a name associated with the source object and link to a property sheet associated with the source object. A corresponding system and computer program product are also disclosed.
