  • Publication number: 20190220038
    Abstract: The present application provides methods and systems for launching an unmanned aerial vehicle (UAV). An exemplary system for launching a UAV includes a detector configured to detect acceleration of the UAV in a launch mode. The exemplary system may also include a memory storing instructions and a processor configured to execute the instructions to cause the system to: obtain a signal configured to notify the UAV to enter the launch mode, determine whether the acceleration of the UAV satisfies a condition corresponding to threshold acceleration in the launch mode, and responsive to the determination that the acceleration of the UAV satisfies the condition, turn on a motor of the UAV.

  • Patent number: 8008365
    Abstract: The present invention discloses methods for enhancing the wear-resistance of polymers, the resulting polymers, and in vivo implants made from such polymers. One aspect of this invention presents a method whereby a polymer is irradiated, preferably with gamma radiation, then thermally treated, such as by remelting of annealing. The resulting polymeric composition preferably has its most oxidized surface layer removed. Another aspect of the invention presents a general method for optimizing the wear resistance and desirable physical and/or chemical properties of a polymer by crosslinking and thermally treating it. The resulting polymeric compositions is wear-resistant and may be fabricated into an in vivo implant.
