Abstract: An unmanned aerial vehicle includes a central body having a plurality of sides and a plurality of arms extendable from the central body. Each arm is configured to support one or more propulsion assemblies that provide a propulsion force while the unmanned aerial vehicle is in flight. The arms are configured to transform between a flight configuration in which the arms are extended away from the central body and a compact configuration in which free ends of a first subset of the arms collectively define a rectangular area. Free ends of a second subset of the arms are closer to a yaw-axis of the unmanned aerial vehicle than the free ends of the first subset of the arms. The yaw-axis passes through the rectangular area.

Abstract: An unmanned aerial vehicle (UAV) comprises a central body, a plurality of arms that extend out from the central body, and a plurality of rotors. Each arm has one or more joints that segment the arm into a stem portion proximal to the central body and one or more branch portions distal to the central body. The one or more joints permit the one or more branch portions to move horizontally relative to the stem portion between an extended state and a compacted state. The one or more branch portions are arranged substantially parallel to a perimeter edge of the central body in the compacted state. Each rotor in the plurality is attached to the one or more branch portions.

Abstract: A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.

Abstract: A prompting device for prompting state information of a physical game character includes a smog machine and a control circuit. The smog machine include a smog chamber, a heating element, and an air-blowing device. The smog chamber has a receiving cavity for receiving smog fluid, an inlet, and an outlet. The inlet and the outlet are in communication with the receiving cavity. The heating element is mourned within the receiving cavity and generates heat to vaporize the smog fluid after an electric current is applied. The air-blowing device is disposed corresponding to the outlet for blowing art air flow towards the receiving cavity. The air flow generated by the air-blowing device enters into the receiving cavity from the inlet and discharges smog within the receiving cavity from outlet. The control circuit is configured to control the smog machine to generate the smog that characterizes the state information.
