Abstract: A computer-implemented method of determining a distance from a display to a user's eye includes estimating, using a first technique, a distance between a display and a user's eye; and repeatedly estimating, using a second technique that is different to the first technique, a distance between the display and the user's eye.

Abstract: This disclosure describes a method of controlling an unmanned aerial vehicle (UAV). The steps of controlling include acquiring images with an image capture device of an unmanned aerial vehicle (UAV). The steps include analyzing the images to determine navigation information of the UAV with a vision-based navigation system. The steps include tracking a position of the UAV with the vision-based navigation system. The steps include controlling rotors of the UAV to prevent deviations in movement from a desired flight path or position of the UAV. The steps include limiting travel or flight of the UAV to a physical region determined by the desired flight path.

Abstract: Approaches for top speed dependent operational parameter configuration are disclosed. An operational parameter to be used by an autonomous vehicle is received. Operational modes and corresponding operational regions are determined based on the received operational parameter. A first set of autonomous vehicle parameters are determined and set based on the received operational parameter. A second set of autonomous vehicle parameters are determined and set based on the first set of autonomous vehicle parameters.

Abstract: This disclosure describes systems and methods for a multipoint cable cam (MPCC) of an aerial vehicle. A method includes operations of receiving user input associated with a predetermined path and correlating the received user input with stored global positioning satellite (GPS) data to generate one or more virtual waypoints along the predetermined path. The method includes processing the one or more virtual waypoints to generate a spline-based flight path. The method may include storing the spline-based flight path and transmitting the spline-based flight path to the aerial vehicle.

Abstract: A system, method, and computer-readable medium are disclosed for managing a manufacturing environment, comprising: providing an Internet of Things (IoT) hub, the IoT hub coordinating communication between a mobile device and a product fabrication system; communicating between the mobile device and the product fabrication system via a secure internal network of the manufacturing environment; maintaining a master version of an application on the IoT hub; and, updating a mobile version of an application on the mobile device using the master version of the application maintained on the IoT hub.

Abstract: A backpack kickstand assembly for supporting a backpack while the backpack is being worn includes a backpack frame that can be worn on a user's back. A backpack is removably mounted to the backpack frame to facilitate the backpack to be carried on the user's back. A kickstand is attachable to the backpack frame and the kickstand is positionable in an extended position to support the weight of the backpack frame while the backpack frame is being worn to facilitate the wearer of the backpack frame to rest. The kickstand is positionable in a retracted position to facilitate the wearer to bear the full weight of the backpack frame.
