  • Patent number: 10508683
    Abstract: The present disclosure described devices and methods for stabilizing a payload. A carrier may be provided. The carrier may manipulate a payload such that the payload is able to rotate about a roll axis by 90 degrees or more. In some instances, the carrier may be directly connected to a component (e.g., gimbal component) configured to permit rotation of the payload about a roll axis. The carrier described herein can have a compact configuration that allows for minimal volume and weight and may be ideally suited for mobile use. Particularly, the carrier may be mounted on an unmanned aerial vehicle (UAV). In some instances, an imaging device may be coupled to the carrier and images having horizontal orientation, vertical orientations, or orientations in-between may be captured and processed.

  • Patent number: 9949124
    Abstract: An authentication system for pairing two or more electronic devices is taught whereby two or more devices, such as cellular phones, receive a first vibration or motion and register a first event, they receive a second vibration or motion and register a second event, the said two or more devices pair or otherwise recognize devices that received first event and second event based on the detected interval between the first and second events. By measuring the interval or phase between two vibration or motion events, the current invention allows pairing without complex movement, without a great amount of a user's attention on the interfaces of the devices, and without the need for compensation between differences in the clocks internal to the devices.
