  • Publication number: 20220333665
    Abstract: The invention relates to a damping assembly for use in an unmanned vehicle. The damping assemblies comprises a positioning structure configured to support one or more components of the unmanned vehicle; a damping system comprising at least one first damping unit and at least one second damping unit arranged at the positioning structure, the at least one first damping unit and the at least one second damping unit being deformable along an axis of deformation of the damping system to thereby reduce transmission of vibration to the supported one or more components; wherein, in response to the force acting upon the positioning structure, the first damping unit is compressed along the axis of deformation, and simultaneously, the second damping unit is extended along the axis of deformation.

  • Patent number: 11167863
    Abstract: The invention relates to an unmanned aerial vehicle (UAV). The UAV comprises a body housing control and wireless communication circuitry for the UAV and a rechargeable power source. The UAV has a plurality of propellers surrounding the body and supported so as to be spaced outwardly from and preferably above the body. A gimbal is mounted under a forward portion of the body for supporting a camera. The gimbal may be arranged under the forward portion of the body such that an angle of a forward vertical field of view of the camera is less than an angle of a forward vertical clearance field of view defined with respect to a forward tip of at least one of the propellers. The gimbal may be arranged under the forward portion of the body such that a lens of a camera supported thereon is substantially in line with a front edge of the UAV body.

  • Publication number: 20210286355
    Abstract: The invention relates to a ground station for a UAV comprising a housing for accommodating a system on chip (SOC) circuit including a control processor for executing software to wirelessly control functions of the UAV, a first screen, and a second screen, wherein one or both screens are controlled directly by the SOC control processor. The housing may comprise a clam shell housing comprising a first housing member for accommodating the control processor and a second housing member movable relative to the first housing member between a first closed position overlaying said first housing member and a second open position. The arrangement is such that the first housing member has mounted thereon the first screen and the second housing member has mounted thereon the second screen such that both screens are viewable by a user when the second housing member is in its open position.
