    Abstract: This disclosure is directed to varying a speed of one or more motors in an unmanned aerial vehicle (UAV) to reduce unwanted sound (i.e., noise) of the UAV. A UAV may include motors coupled with propellers to provide lift and propulsion to the UAV in various stages of flight, such as while ascending, descending, hovering, or transiting. The motors and propellers may generate noise, which may include a number of noise components such as tonal noise (e.g., a whining noise such as a whistle of a kettle at full boil) and broadband noise (e.g., a complex mixture of sounds of different frequencies, such as the sound of ocean surf). By varying the controls to the motors, such as by varying the speed or revolutions per minute (RPM) of a motor during operation by providing random or pseudo-random RPM variations, the UAV may generate a noise signature with reduced tonal noise.

    Abstract translation: 本公开涉及改变无人机（UAV）中的一个或多个电动机的速度以减少无人机的不想要的声音（即噪声）。 无人机可以包括与螺旋桨耦合的电动机，以在飞行的各个阶段（例如上升，下降，悬停或过渡）中向无人机提供升力和推进。 电动机和螺旋桨可能产生噪音，其可能包括许多噪声分量，例如音调噪声（例如，在完全沸腾时，诸如壶的口哨声等）和宽带噪声（例如，不同的声音的复杂混合 频率，如海浪的声音）。 通过改变对电动机的控制，例如通过提供随机或伪随机RPM变化来改变电动机在运行期间的速度或转数（RPM），UAV可以产生具有降低的音调噪声的噪声特征。

    Abstract: An unmanned aerial vehicle (i.e., drone) has a main body having top and bottom halves shaped to resemble beverage bottle caps, and hinged to one another in a clamshell arrangement to surround an interior compartment. The main body is mounted on a landing gear structure having at least two support legs. For propulsion, multiple rotors (e.g., 4 to 6) are each mounted on collapsible booms that are hingedly mounted to the frame structure of the landing gear assembly. The unmanned aerial vehicle is equipped with spotlights, LEDs that change color, laser lights, strobe lights, multiple speakers, a video display screen, a video camera, a video projector, a satellite/GPS antennae, a digital music storage and playing device, a voice recording and playback device connected to the multiple speakers, at least one battery power source and a computer control module (CPU) for wireless communication with a remote control device.

    Abstract: A tethered flight control system for a small unmanned aircraft. The tethered flight control system can have a mobile base, a tether arm, a tether spout, and a remote-controlled winch that can hold a tether line, which can be connected to a small unmanned aircraft. By controlling the tether line using the winch, the small unmanned aircraft can be prevented from flying out of range or out of control. The winch can have a high-speed motor configured to remove substantially all slack from the tether line while the small unmanned aircraft is in flight. The winch can be controlled from a hard-wired winch remote, which can take the form of a foot pedal device having one or more foot pedals. The tether line can be attached to the small unmanned aircraft through a tether attachment apparatus, which can have a travel bar, two or more rotor protectors, and a mounting section.

    Abstract: Vehicles such as unmanned air vehicles that are capable of movement from an open, flight configuration to an enclosed configuration in which all major flight components can be protected by an outer shell are disclosed. In the enclosed configuration, the vehicles can take on standard geometric shapes such as a rectangular prism, sphere, cylinder, or another shape, so as to not be recognizable as an unmanned air vehicle. Embodiments of vehicles can also include interchangeable and/or wireless motor arms, motor arms which are electrically connected to the remainder of the vehicle only when in an open configuration, remote controllers removably attached to the remainder of the vehicle, and clip or other attachment mechanisms for attachment to objects such as backpacks.
