Patent number: 11997249Abstract: Eyewear devices that include two SoCs that share processing workload. Instead of using a single SoC located either on the left or right side of the eyewear devices, the two SoCs have different assigned responsibilities to operate different devices and perform different processes to balance workload. In one example, the eyewear device utilizes a first SoC to operate a first color camera, a second color camera, a first display, and a second display. The first SoC and a second SoC are configured to selectively operate a first and second computer vision (CV) camera algorithms. The first SoC is configured to perform visual odometry (VIO), track hand gestures of the user, and provide depth from stereo images. This configuration provides organized logistics to efficiently operate various features, and balanced power consumption.Type: GrantFiled: October 14, 2021Date of Patent: May 28, 2024Assignee: Snap Inc.Inventors: Jason Heger, Gerald Nilles, Dmitry Ryuma, Patrick Timothy Mcsweeney Simons, Daniel Wagner

Patent number: 11990989Abstract: An electronic eyewear device includes first and second systems-on-chip (SoCs) having independent time bases. The first and second SoCs are connected by a shared general purpose input/output (GPIO) connection and an inter-SoC interface. The first and second SoCs are synchronized to each other by the first SoC asserting the shared GPIO connection to the second SoC where assertion of the message to the shared GPIO connection triggers an interrupt request (IRQ) at the second SoC. The first SoC records a first timestamp for assertion of the message to the GPIO connection, and the second SoC records a second timestamp of receipt of the IRQ. The first SoC sends a message including the first timestamp to the second SoC over the inter-SoC interface. The second SoC calculates a clock offset between the first and second SoCs as a difference between the first and second timestamps.Type: GrantFiled: October 7, 2021Date of Patent: May 21, 2024Assignee: Snap Inc.Inventors: Samuel Ahn, Dmitry Ryuma, Richard Zhuang

Publication number: 20230393609Abstract: An electronic eyewear device includes first and second systems on a chip (SoCs) having independent time bases that are synchronized by generating a common clock signal from a clock generator of the first SoC and simultaneously applying the common clock signal to a first counter of the first SoC and a second counter of the second SoC whereby the first counter and the second counter count clock edges of the common clock. The clock counts are shared through an interface between the first SoC and the second SoC and compared to each other. When the clock counts are different, a clock count of the first counter or the second counter is adjusted to cause the clock counts to match each other. The adjusted clock count is synchronized to the respective clocks of the first and second SoCs, thus synchronizing the first and second SoCs to each other.Type: ApplicationFiled: August 22, 2023Publication date: December 7, 2023Inventors: Samuel Ahn, Jason Heger, Dmitry Ryuma

Publication number: 20230350206Abstract: Devices and methods for dynamic power configuration (e.g., reduction) for thermal management (e.g., mitigation) in a wearable electronic device such as an eyewear device. The wearable electronic device monitors its temperature and, responsive to the temperature, configures the services it provides to operate in different modes for thermal mitigation (e.g., to prevent overheating). For example, based on temperature, the wearable electronic device adjusts sensors (e.g., turns cameras on or off, changes the sampling rate, or a combination thereof) and adjusts display components (e.g., adjusted rate at which a graphical processing unit generates images and a visual display is updated). This enables the wearable electronic device to consume less power when temperatures are too high in order to provide thermal mitigation.Type: ApplicationFiled: July 6, 2023Publication date: November 2, 2023Applicant: Snap Inc.Inventors: Sumant Hanumante, Bernhard Jung, Matthias Kalkgruber, Anton Kondratenko, Edward Lee Kim-Koon, Gerald Nilles, John James Robertson, Dmitry Ryuma, Alexander Sourov, Daniel Wolf

Publication number: 20230109476Abstract: An electronic eyewear device includes first and second systems on a chip (SoCs) having independent time bases and an inter-SoC interface that connects the first and second SoCs. The operations of the first and second SoCs are synchronized by aligning the time bases for the SoCs using a modified PTP technique. The technique includes the second SoC receiving a time synchronization message from the first SoC over the inter-SoC interface, recording a local timestamp of receipt of the time synchronization message, receiving a master timestamp corresponding to a timestamp recorded by the first SoC corresponding to the time of sending the time synchronization message by the first SoC, and calculating a time offset between the local timestamp and the master timestamp. The time bases of the first SoC and second SoC are then aligned using the calculated time offset. To account for transmission delays, multiple time offsets may be averaged.Type: ApplicationFiled: October 4, 2021Publication date: April 6, 2023Inventors: Samuel Ahn, Dmitry Ryuma
