Abstract

Eyewear including a frame having a first side and a second side, a first temple extending from the first side of the frame, a second temple extending from the second side of the frame, electronic components, a first system on a chip (SoC) adjacent the first side of the frame coupled to a first set of the electronic components, and a second system on a chip adjacent the second side, the second SoC coupled to the first SoC and to a second set of the plurality of electronic components. Processing workloads are balanced between the first SoC and the second SoC by performing a first set of operations with the first SoC and performing a second set of operations with the second SoC.

First claim

What is claimed is:

1 . Eyewear, comprising:
a frame having a first side and a second side; a first temple extending from the first side of the frame; a second temple extending from the second side of the frame; a first camera and a first display; a second camera and a second display; a passive thermal cooling capacity of approximately 2 to 3 Watts adjacent each of the first and second sides, a first system on a chip (SoC) adjacent the first side of the frame, the first SoC coupled directly to the first camera and the first display, the first SoC having a first image signal processor (ISP) to capture images and a first graphical processing unit (GPU) to render images; and a second system on a chip adjacent the second side, the second SoC coupled directly to the second camera and the second display, the second SoC having a second ISP to capture images and a second GPU to render images.

2 . The eyewear of claim 1 , wherein the first SoC has first total processing resources and the second SoC has second total processing resources equivalent to the first total processing resources.

3 . The eyewear of claim 2 , wherein the first SoC is at least substantially identical to the second SoC.

4 . The eyewear of claim 1 , further comprising load balancing instructions for execution on the first and second SoCs, the load balancing instructions, when executed by the first and second SoCs, shift processing workload between the first and second SoCs.

5 . The eyewear of claim 4 , further comprising:
a first temperature sensor adjacent the first SoC, the first temperature sensor generating a first temperature value; and a second temperature sensor adjacent the second SoC, the second temperature sensor generating a second temperature value; wherein the load balancing instructions configure the first and second SoCs to shift the processing workload responsive the first and second temperature values.

6 . The eyewear of claim 1 , further comprising:
a first battery and a first flash memory coupled to the first SoC; and a second battery and a second flash memory coupled to the second SoC.

7 . The eyewear of claim 1 , wherein the first and second SoCs each perform computer vision, machine learning, and video encoding.

8 . The eyewear of claim 1 , further comprising:
first display components for the first display adjacent the first side; and second display components for the second display adjacent the second side.

9 . The eyewear of claim 8 , wherein each of the first and second SoCs operates at approximately 1.5 Watts or less and each of the first and second display components operate at approximately 1 to 2 Watts.

10 . A load balancing method for use in eyewear including a frame having a first side and a second side, a first temple extending from the first side of the frame, a second temple extending from the second side of the frame, and a plurality of electronic components, the method comprising:
performing a first set of operations with a first SoC positioned adjacent the first side of the frame, the first SoC coupled directly to a first camera and a first display, the first SoC having a first image signal processor (ISP) to capture images and a first graphical processing unit (GPU) to render images; performing a second set of operations with a second SoC positioned adjacent the second side of the frame, the second SoC coupled directly to a second camera and a second display, the second SoC having a second ISP to capture images and a second GPU to render images; and cooling the eyewear with a passive thermal cooling capacity of approximately 2 to 3 Watts adjacent each of the first and second sides.

11 . The method of claim 10 , wherein the first SoC is at least substantially identical to the second SoC.

12 . The method of claim 10 , further comprising:
shifting one or more operations between the first and second sets of operations to balance processing workload between the first and second SoCs.

13 . The method of claim 12 , further comprising:
monitoring a first temperature value adjacent the first SoC; and monitoring a second temperature value adjacent the second SoC; wherein the shifting of the one or more operations is responsive to the first and second temperature values.

14 . The method of claim 10 , wherein the first and second set of operations each comprise performing computer vision, machine learning, and video encoding.

15 . The method of claim 10 , wherein the eyewear further comprises first display components for the first display adjacent the first side and second display components for the second display adjacent the second side, wherein the first set of operations and the second set of operations are each performed using approximately 1.5 Watts or less.

16 . A non-transitory computer readable medium including instructions for load balancing eyewear including a frame having a first side and a second side, a first temple extending from the first side of the frame, a second temple extending from the second side of the frame, and a plurality of electronic components, the instructions when executed by the eyewear configures the eyewear to:
perform a first set of operations with a first SoC positioned adjacent the first side of the frame, the first SoC coupled directly to a first camera and a first display, the first SoC having a first image signal processor (ISP) to capture images and a first graphical processing unit (GPU) to render images, wherein the eyewear further comprises a passive thermal cooling capacity of approximately 2 to 3 Watts adjacent the first side; and perform a second set of operations with a second SoC positioned adjacent the second side of the frame, the second SoC coupled directly to a second camera and a second display, the second SoC having a second ISP to capture images and a second GPU to render images, wherein the eyewear further comprises a passive thermal cooling capacity of approximately 2 to 3 Watts adjacent the second side.

17 . The non-transitory computer readable medium of claim 16 , wherein the instructions when executed by the eyewear further configures the eyewear to:
shift one or more operations between the first and second sets of operations to balance processing workload between the first and second SoCs.

18 . The non-transitory computer readable medium of claim 17 , wherein the instructions when executed by the eyewear further configures the eyewear to:
monitor a first temperature value adjacent the first SoC; and monitor a second temperature value adjacent the second SoC; wherein the shift of the one or more operations is responsive to the first and second temperature values.

19 . The non-transitory computer readable medium of claim 16 , wherein the first and second set of operations each comprise performing computer vision, machine learning, and video encoding.

20 . The non-transitory computer readable medium of claim 16 , wherein the eyewear further comprises first display components for the first display adjacent the first side and second display components for the second display adjacent the second side, wherein the first set of operations and the second set of operations are each performed using approximately 1.5 Watts or less.
