Abstract: A processing unit of an electronic device may transmit a synchronization pulse to each of a first plurality of motion sensors (e.g., Inertial Measurement Units or IMUs) communicatively coupled to the processing unit, wherein the synchronization pulse transmitted to each motion sensor of the first plurality of motion sensors is assigned an offset time amount by the processing unit. The processing unit then obtains motion information samples from each of the first plurality of motion sensors, e.g., in an order corresponding to the offset time amounts assigned to the respective motion sensors, and then performs a processing operation based upon the obtained motion information samples. In some embodiments, each motion sensor may be assigned an equal offset time amount. In other embodiments, the offset time amount assigned to each motion sensor may be individually determined, e.g., based on one or more conditions, settings, or preferences related to the electronic device.

Abstract: In some implementations, a method of synchronizing a content generation and delivery architecture to reduce the latency associated with image passthrough. The method includes: determining a temporal offset associated with the content generation and delivery architecture to reduce a photon-to-photon latency across the content generation and delivery architecture; obtaining a first reference rate associated with a portion of the content generation and delivery architecture; generating, via synchronization circuitry, a synchronization signal for the content generation and delivery architecture based at least in part on the first reference rate; and operating the content generation and delivery architecture according to the synchronization signal and the temporal offset.
