Abstract: A propeller blade comprises a blade root coupled to a rotor hub and a blade tip. The propeller blade is composed of airfoil cross-sections, each cross-section a distance away from the rotor hub. Each airfoil is designed with particular structural characteristics that improve the overall amount of thrust generated on the quadcopter. Namely, each airfoil possesses a ? angle and chord length whose values depend on the distance of that airfoil from the rotor hub. For example, the relationship between an airfoil's ? angle and its distance from the rotor hub is described by a power law. Additionally, the relationship between an airfoil's chord length and its distance from the rotor hub is described using a polynomial regression. Compared to current, off the shelf propeller blades, the current propeller blade embodiment achieves the same thrust at a lower RPM, thereby yielding benefits in reduced acoustic noise and improved response time.

Abstract: The disclosure relates to technology for reference counting. A parent thread counter corresponding to an object is created by a parent thread, where the parent thread counter includes a hierarchical counter data structure. A child thread counter of a child thread is created that includes the hierarchical counter data structure and passes the reference to the object from the parent thread to the child thread. The hierarchical counter data structure is updated in the parent thread counter to reference the child thread counter and in the child thread counter to point to the parent thread counter. The parent thread counter is then when the child thread has completed processing. As part of the updating, the parent and child thread counters employ a lock-free mechanism.
