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 the OS, a first color camera, a second color camera, a first display, and a second display. A second SoC is configured to run computer vision (CV) algorithms, visual odometry (VIO), tracking hand gestures of the user, and providing depth from stereo. This configuration provides organized logistics to efficiently operate various features, and balanced power consumption.

Dual system on a chip eyewear

A method of dissipating heat generated by imaging devices and processing devices of a wearable electronic eyewear device includes providing a first heat sink thermally connecting the imaging devices to a frame of the eyewear device to sink heat to the frame and providing a second heat sink thermally connecting the processing devices to respective temples of the eyewear device to sink heat to the respective temples. The first and second heat sinks are thermally insulated from each other to direct the heat to different portions of the eyewear device. The processing devices may include a first co-processor disposed in a first temple connected to a first end of the frame and a second co-processor disposed in a second temple connected to a second end of the frame. The resulting eyewear device spreads the heat from heat generating devices over a larger area to minimize overall heating.

Thermal architecture for smart glasses

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 displays, and it performs three-dimensional graphics and compositing. A second SoC operates first and second color cameras, first and second computer vision (CV) cameras, an operating system (OS), CV algorithms, and visual odometry (VIO), and it performs hand gesture tracking of the user and provides depth from stereo images. This configuration provides organized logistics to efficiently operate various features, and balanced power consumption.

Eyewear with a slot ring antenna generating orthogonal E-fields. The slot ring antenna has a first portion including an inner ring and an outer ring generating a first direction E-field, and a second portion having a respective inner ring and the outer ring generating a second direction E-field. The outer ring encompasses the respective inner rings, where a first slot is defined between the respective inner ring and the outer ring. A second slot is encompassed by the respective inner ring, which may be a cutout. The slot ring antenna encompasses eyewear optical assemblies. In one example, the first portion encompasses a first optical assembly, and the second portion encompasses a second optical assembly. A common ground plane of the outer ring may extend proximate a bridge of the eyewear.

Eyewear with slot-ring antenna

Eyewear including a dipole antenna having a first leg and a second leg, wherein the first leg includes at least a portion of a battery, such as a conductive case of the battery. An antenna feed is coupled to the dipole antenna between the second leg and the battery. The second leg may comprise a flexible printed circuit (FPC), and the second leg is an active leg. The second leg has a first portion and a second portion. The first portion and the second portion may have the same physical length. The first portion may be dielectrically loaded with a high permittivity loaded material, and the second portion may be dielectrically loaded with a low permittivity loaded material.

Eyewear with aperture tuned dielectric loaded multi-band antenna

An antenna that is coupled to and integrated with a projector, such as a projector included with smart glasses including eyewear. The projector has a housing and includes optical components configured to display an image. At least one antenna is coupled to the projector, wherein the optical components operate and function as an antenna substrate. The optical components are nonmetallic such that the antenna generates a strong E-field. The antenna may be coupled to the projector housing, such as on the inside or the outside surface of the housing. Multiple antennas can be included to generate multiple resonances simultaneously in different frequency bands.

Projector with integrated antenna

Eyewear device that includes two SoCs that share processing workload. Instead of using a single SoC located either on the left or right side of the eyewear device, 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 all peripheral components, and a second SoC performing computational tasks. This is a low-risk architecture since the second SoC is not required to operate any of the peripherals, and it has low standby power since the second SoC can be fully shutdown in a low-power mode. The second SoC does not have any direct access to camera data, so an interprocessor communication bus continuously transmits camera buffer data for most augmented reality (AR) compute tasks. This configuration provides organized logistics to efficiently operate various features, and balanced power consumption.

The power source also includes power flow devices coupled to the battery units that are configured to provide power from the battery units to the system load. Each power flow device corresponds to a respective one of the battery units and includes a one direction current flow device connected in series with a current regulator between the respective battery unit and the system load.

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.

The slot ring antenna has a first portion including an inner ring and an outer ring configured to generate a first E-field in a first direction, and a second portion having a respective inner ring and the outer right configured to generate a second E-field in a second direction that is orthogonal to the first E-field. The outer ring encompasses the respective inner rings, where a first slot is defined between the respective inner ring and the outer ring. A second slot is encompassed by the respective inner ring, and it may be a cutout. The slot ring antenna encompasses eyewear optical assemblies. In one example, the slot antenna first portion encompasses a first optical assembly, and the second portion encompasses the second optical assembly. The outer ring may comprise of a common ground plane, which ground plane may extend proximate a bridge of the eyewear. The two portions of the antenna co-exist in very close proximity to each other and support the same frequency band with minimal coupling to each other due to the orthogonal E-fields.
