    Abstract: Systems, computer readable medium and methods for autonomous drone navigation based on vision are disclosed. Example methods include capturing an image using an image capturing device of the autonomous drone, processing the image to identify an object, and navigating the autonomous drone relative to the object for a period of time. After the period of time a second type of navigation is used based on determining structure from motion navigation. Images are captured during the period of time to transition to the second type of navigation. The second type of navigation uses a downward pointing navigation camera and other sensors.

    Abstract: A projector having a curved field lens and a displaced light modulating display. The system includes at least one light source configured to generate colored light beams, and a prism routing the light beams to the display. The curved field lens is coupled to a face of the prism, and the prism and curved field lens together decenter the light beam from the prism face and uniformly illuminate the display. A center of the display is displaced from the projection lens optical axis. The decentered light beam and the displaced display together generate a favorable shifted boresight of the created image. Dimensions of components of the projector are a function of a curvature of the curved field lens. The greater the curvature of the curved field lens, the smaller the dimensions of the components and the overall projector. The projector may be used in eyewear.

    Abstract: An antenna that is coupled to and integrated with a projector, such as a projector included with smart glasses including eyewear. The projector has a housing and includes optical components configured to display an image. At least one antenna is coupled to the projector, wherein the optical components operate and function as an antenna substrate. The optical components are nonmetallic such that the antenna generates a strong E-field. The antenna may be coupled to the projector housing, such as on the inside or the outside surface of the housing. Multiple antennas can be included to generate multiple resonances simultaneously in different frequency bands.
