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: 20230344929Abstract: Systems and methods for generating an alert on an eyewear device are provided. The systems and methods include receiving, by an eyewear device, from a mobile device, data indicative of a first combination of notification attributes that trigger a first alert on the eyewear device; determining that the mobile device has received a new notification based on additional data received from the mobile device; determining that a combination of attributes of the new notification matches the first combination of notification attributes; and in response to determining that the combination of the attributes of the new notification matches the first combination of notification attributes, retrieving, from a storage device of the eyewear device, a first visual indicator animation that represents the first alert; and activating a visual indicator of the eyewear device in accordance with the retrieved first visual indicator animation to generate the first alert on the eyewear device.Type: ApplicationFiled: June 30, 2023Publication date: October 26, 2023Inventors: John James Robertson, Andrew Joseph Bartow, Samuel Ahn, Matthew Du

Publication number: 20230113076Abstract: 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: ApplicationFiled: October 7, 2021Publication date: April 13, 2023Inventors: Samuel Ahn, Dmitry Ryuma, Richard Zhuang

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
