Methods and devices for wired charging and communication with a wearable device are described. In one embodiment, a symmetrical contact interface comprises a first contact pad and a second contact pad, and particular wired circuitry is coupled to the first and second contact pad to enable charging as well as receive and transmit communications via the contact pads as part of various device states.

Circuits and methods for wearable device charging and wired control

Eyewear including a sensor integrated into frame of eyewear. In one example, the sensor comprises a strain gauge, such as a metallic foil gauge, that is configured to sense and measure distortion of the frame when worn by a user and under different force profiles, by measuring a strain in the frame when bent. The measured strain by strain gauge is sensed by a processor, and the processor performs dynamic calibration of image processing based on the measured strain. The distortion measured by the strain gauge is used by the processor to correct calibration of the cameras, and the displays.

Eyewear with strain gauge estimation

An eyewear device that accurately and dynamically adjusts color and brightness of a see-through display as a function of a user's eye gaze direction and eye position using a display characteristic map. The display characteristic map is indicative of display characteristics of the see-through display. Color masks are generated as a function of the display characteristic map and the user's eye gaze direction and eye position, and a processor adjusts the see-through display characteristics based on the color masks.

Dynamic display color adjustment by eye tracking

Systems, computer readable medium and methods for unlocking an autonomous drone are disclosed. Example methods include receiving an indication of a selection of a fly instruction, capturing an image using an image capturing device of the autonomous drone, processing the image to determine whether a face is present in the image, and if the face is present in the image, taking off. The face has to be within a predetermined distance of the autonomous drone. This ensures that the face is likely from the person that selected the fly instruction and ensures that the autonomous drone is far enough away from the face that the autonomous drone will not crash into the face on take-off. In some examples, the autonomous drone determines whether the autonomous drone is sitting on a hand before taking off. The autonomous drone uses a position of the face to determine an initial flight plan.

Unlocking an autonomous drone for takeoff

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

System, methods, devices, and instructions are described for fast boot of a processor as part of camera operation. In some embodiments, in response to a camera input, a digital signal processor (DSP) of a device is booted using a first set of instructions. Capture of image sensor data is initiated using the first set of instructions at the DSP. The DSP then receives a second set of instructions and the DSP is programmed using the second set of instructions after at least a first frame of the image sensor data is stored in a memory of the device. The first frame of the image sensor data is processed using the DSP as programmed by the second set of instructions. In some embodiments, the first set of instructions includes only instructions for setting camera sensor values, and the second set of instructions includes instructions for processing raw sensor data into formatted image files.

Systems and methods for DSP fast boot

Systems, computer readable medium and methods for fully autonomous drone flight are disclosed. Example methods include taking off, navigating in accordance with a flight plan, and navigating the autonomous drone to land. The autonomous drone performs flight plans with only an initial command for the autonomous drone to fly and, in some examples, an indication of a landing space such as an open hand presented under the autonomous drone. After an initial fly command, the autonomous drone is not controlled by a remote-control device and does not receive any additional commands to complete the flight plan. The autonomous drone enters a lower energy state while flying where the wireless connections are turned off since the autonomous drone does not respond to commands during flight.

Fully autonomous drone flights

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

Eyewear with camera-based compensation that improves the user experience of eyewear devices for user's having partial blindness or complete blindness. To compensate for blindness, the camera-based compensation uses eyewear cameras to communicate a video feed, and a microphone to provide an optional audio feed, to a remote operator of a remote device to responsively assist the user to complete a task. For example, the user may want audio advice on how to navigate a crowded scene or unknown obstacle. The camera-based compensation is configured to receive instructions from the remote operator to navigate, such as by receiving audio instructions.

An antenna system comprises a combination of a loop antenna and a non-loop antenna. The loop antenna and the non-loop antenna is connected in common to a transceiver mechanism or signal feed mechanism. The non-loop antenna is in some embodiments provided by a dipole conductor. An eyewear device incorporates the antenna system, a loop conductor and a dipole conductor of the antenna system being integrated in a body of the eyewear device. The loop conductor may be provided by a lens ring that extends around a lens held by the body. The lens ring may serve both as loop conductor and as a lens retention mechanism.

Hybrid antenna system for wearable devices

Methods and devices for wired charging and communication with a wearable device are described. In one embodiment, a symmetrical contact interface comprises a first contact pad and a second contact pad, and particular wired circuitry is coupled to the first and second contact pads to enable charging as well as receive and transmit communications via the contact pads as part of various device states.

An antenna system comprises a driven antenna element connected to a printed circuit board (PCB), and a plurality of PCB extenders provided by electrical conductors connected to a PCB ground plane for cooperation with the driven antenna element in signal communication. In an eyewear device that incorporates the antenna system, the plurality of PCB extenders are provided by conductive structural elements incorporated in an eyewear frame.

Wearable device antenna system

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

Systems, computer readable medium and methods for improved boot time for autonomous drones are disclosed. Autonomous drones are disclosed that include an Off State and a Power off State. The Off State appears to a user of the autonomous drone as if the autonomous drone is off, but the Off State maintains some of the autonomous drone's state such as the operating system being loaded in a memory. The autonomous drone enters the Power off State, where all or substantially all the power is turned off, from the Off State based on a timeout or a power level of a battery dropping below a threshold level. The Off State reduces the boot time of the autonomous drone compared with the Power off State. The time reduction is often less than ten seconds, but this time is beneficial for situations where a user would like the autonomous drone to immediately perform photography.
