A system for hand tracking for an Augmented Reality (AR) system. The AR system uses a camera of the AR system to capture tracking video frame data of a hand of a user of the AR system. The AR system generates a skeletal model based on the tracking video frame data and determines a location of the hand of the user based on the skeletal model. The AR system causes a steerable camera of the AR system to focus on the hand of the user.

Steerable camera for AR hand tracking

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

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

Head-wearable apparatus to generate binaural audio content includes a first stem coupled to a first microphone housing that encases first front microphone and first rear microphone that generates acoustic signals, respectively. First microphone housing includes a first front port that faces downward and a first rear port that faces backwards. Apparatus includes second stem coupled to second microphone housing that encases second front microphone and second rear microphone that generate acoustic signals, respectively. Second microphone housing includes second front port that faces downward and second rear port that faces backwards. Apparatus includes binaural audio processor that includes beamformer and storage device. Beamformer generate first beamformer signal based on acoustic signals from first front microphone and first rear microphone, and second beamformer based on acoustic signals from second front microphone and second rear microphone. Storage device stores first and second beamformer signals as a two-channel file.

Apparatuses and systems for wearable devices such as eyewear are described. According to one embodiment, the wearable device includes a frame, onboard electronics components, and an antenna disposed around an eyepiece area of the frame that is configured to hold an optical element. The antenna is configured for inductive coupling. In some embodiments, a switch coupled to the antenna allows selection between circuitry for inductive charging of a battery and near-field communication (NFC) circuitry for communicating data via the antenna.

Systems and methods for managing temperatures of wearable device components are disclosed. In one aspects, a method includes determining a temperature of an electronic component of the wearable device, determining a rate of temperature change of the electronic component, and determining whether to increase or decrease a transmission rate limit of the electronic component based on the temperature and the rate, adjusting the transmission rate limit based on the determination, and limiting a rate of transmission of the electronic component based on the adjusted transmission rate limit.

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 eye-wear 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.

An eyewear device has an antenna system having at least one element which contributes to wireless signal transmission, and which is thermally connected to a heat-generating electronic component of the eyewear device to serve as a heat sink for the electronic component. A driven antenna element and/or a plurality of PCB extenders electrically connected to a PCB ground plane can thus be employed for both signal transmission and heat management.

Heat management in wireless electronic devices

A RF wireless charging enclosure configured to enable efficient wireless charging of a CE device in the enclosure while also allowing wireless communication of the CE device to devices outside the enclosure. In one example, time multiplexing is used such that the CE device is enabled to either be charged, or to communicate with a device outside the enclosure. In another example, frequency division is used such that the CE device is charged at a first frequency, and simultaneously communicates through the enclosure at a second different frequency.

Camera compensation methods and systems that compensate for misalignment of sensors/camera in stereoscopic camera systems. The compensation includes identifying a pitch angle offset between a first camera and a second camera, determining misalignment of the first and second cameras from the identified pitch angle offset, determining a relative compensation delay responsive to the determined misalignment, introducing the relative compensation delay to image streams produced by the cameras, and producing a stereoscopic image on a display from the first and second image streams with the introduced delay.

Sensor misalignment compensation

Disclosed herein are regulated power supplies. The power source delivers power to a system load and includes battery units. The power source also includes power flow devices coupled to the battery units that are configured to provide power from the battery units to the system load. Each power flow device corresponds to a respective one of the battery units, and includes a one direction current flow device connected in series with a current regulator between the respective battery unit and the system load.
