Systems, computer readable medium and methods for autonomous drone stabilization and navigation 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 to one or more waypoints. The autonomous drone navigates initially based on a relative location of the autonomous drone from the object. The autonomous drone determines a distance from the object based on an estimated size of the object and a number of pixels of an image sensor the object occupies. The autonomous drone determines a height above a ground to assist in navigation. Additionally, the autonomous drone hovers to determine a windspeed.

Stabilization and navigation of an autonomous drone

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.

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.

Autonomous drone navigation based on vision

Systems, computer readable medium and methods for navigation correction for excessive wind in an autonomous drone are disclosed. Excessive winds can be a particular problem for small autonomous drones as safety and retrieval of the autonomous drones is important and the autonomous drones often have limited thrust and batteries. Autonomous drones are disclosed that detect and correct flight plans when excessive winds are detected. The autonomous drone determines based on the severity of the excessive winds whether to return to a home position which is typically a position of a user of the autonomous drone or to land in place. If the excessive winds subside, then the autonomous drone returns to its original flight plan at the point where the autonomous drone was blown off course by the excessive winds. The autonomous drone detects excessive winds either directly by sensor data or inferentially by unanticipated movement of the autonomous drone.

Navigation correction for excessive wind

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.

The present application discloses examples of various apparatuses and systems that can be utilized for augmented reality. According to one example, a wearable device that can optionally comprise: a frame configured for wearing by a user; one or more optical elements mounted on the frame; an array having a plurality of light emitting diodes coupled to the one or more optical elements, wherein the one or more optical elements and the array are mounted within a field of view of the user when the frame is worn by the user; and additional onboard electronic components carried by the frame including at least a battery that is configured to provide for electrically powered operation of the array.

An eyewear device provides for routing a flexible conductive element or conductor through a hollow interior of a hinge mechanism that connects a temple of the eyewear device to its. The hinge mechanism comprises a pair of hinge pieces that defines a composite conduit through the hinge mechanism, conduit and hence the conductor routed through the passage being hidden or obscured from external view in any operational position of the hinge mechanism.

Conductive connection through eyewear hinge

A lightweight stacked optical waveguide using two plastic substrates having nano-structure gratings and a single glass substrate sandwiched between them. The nano-structure gratings face each other, and are each encapsulated within the optical waveguide. The two plastic substrates are each adhesively secured to the central glass substrate rather than to each other to provide sufficient securing strength and precisely establish and maintain an air gap between the substrates. The thickness of the plastic substrates and the glass substrate are selected such that the stacked optical waveguide is lightweight, but also has sufficient drop performance. The stacked optical waveguide can be efficiently manufactured as the adhesive bonds a plastic substrate to a glass substrate.

Waveguide with 2-layer stack-up

Methods of fabricating a waveguide module are presented that include the steps of providing a glass substrate having first and second substantially planar parallel surfaces and comprising one or more cells in a first arrangement and singulating the glass substrate to produce one or more singulated cells. Singulated cells are treated with a chemical agent, laminated to a carrier substrate, processed, and delaminated from the carrier wafer and optionally subjected to further processing.

An eyewear device provides for routing a flexible conductive element or conductor through a hollow interior of a hinge mechanism that connects a temple of the eyewear device to its lens-supporting frame. The conductor establishes an electrically conductive connection between electronic components housed in the frame and the temple respectively. The hinge mechanism comprises a pair of hinge pieces that defines a composite conduit through the hinge mechanism, the conduit and hence the conductor routed through the passage being hidden or obscured from external view in any operational position of the hinge mechanism.
