Abstract: A method for managing power resource in an augmented reality (AR) device is described. In one aspect, the method includes configuring a low-power mode to run on a low-power processor of the AR device using a first set of sensor data, and a high-power mode to run on a high-power processor of the AR device using a second set of sensor data, operating, using the low-power processor, a low-power application in the low-power mode based on the first set of sensor data, detecting a request to operate a high-power application at the AR device, in response to detecting the request, activating the second set of sensors of the AR device corresponding to the high-power mode, and operating, using the high-power processor, a high-power application in the high-power mode based on the second set of sensors.

Abstract: The present disclosure relates to chain monitoring systems and methods. In particular, the chain monitoring system is configured to mount onto a portion of a chain and measure one or more parameters associated with one or more characteristics of the chain. The measured parameters are processed by the chain monitoring system and/or transmitted to a remote system for analysis. The analysis may be used to determine a characteristic and/or change in the characteristic of the chain. In some examples, the characteristic is an elongation value associated with the chain, which can be transmitted to a networked system for analysis, display, and/or control. In some examples, a sensor can be employed to measure one or more characteristics of the chain. The sensor may include, but is not limited to, a strain gauge, an accelerometer, an optical, a sonic, and/or a magnetic sensor.

Abstract: Eyewear providing a visual indicator to a hearing-impaired user indicating a direction of arrival of a sound relative to the eyewear to help the user obtain greater awareness of the surrounding environment. An eyewear optical assembly includes an image display displaying the visual indicator discernable by the user and corresponding to the direction of arrival of the sound, even when a sound source is not viewable through the optical assembly. The image display also displays an image indicative of the sound source. A front portion of an eyewear frame includes a light array, where one or more lights of the light array is illuminated to indicate the direction of arrival and intensity of the sound source. An array of vibrating devices may also be used to indicate the direction of arrival and intensity of the sound source.

Abstract: An electronic eyewear device includes a display and a speaker system adapted to present augment reality objects and associated sounds in a scene being viewed by the user. A processor receives one or more audio tracks respectively associated with one or more augmented reality objects, encodes the audio tracks into an aggregated audio track including the audio tracks, a header for each audio track that uniquely identifies each respective audio track, and an aggregate header that identifies the number of tracks in the aggregated audio track. The processor transfers the aggregated audio track to an audio processor that uses the header for each audio track and the aggregate header to separate the audio tracks from the aggregated audio track. The audio processor processes the audio tracks independently in parallel and provides the audio tracks to the speaker system for presentation with the augmented reality objects.
