Abstract: Aspects of the present disclosure are directed to an artificial reality system orchestrating interactions between virtual object “augments.” The orchestration can include linking, which can be forming two or more augments into a combination, embedding an augment within an existing combination, or triggering an action mapped to the linking of those augments. Another type of orchestration can include extracting, which can refer to taking an augment out of an existing combination, either by removing it from the combination or copying the augment to leave a version in the combination and having another version outside the combination.

Abstract: An eye tracking system for a head-mounted devices includes an interference pattern emitter, an interference pattern detector, and processing logic. The interference pattern emitter provides at least two light beams that combine into a light pattern in an eyebox region of the head-mounted device. The light pattern includes an interference pattern based on constructive and destructive interference of the at least two light beams. The light detector is configured to detect a portion of the light pattern and provides detector data that is representative of one or more light intensities in the portion of the light pattern. The processing logic is coupled to the light detector to receive the detector data and is configured to identify displacement characteristics of the interference pattern. The processing logic is configured to determine orientation characteristics of an eye in the eyebox region based on the displacement characteristics.

Abstract: Methods and systems for reducing electromagnetic interference in analog circuit of a control device for an augmented reality (AR) or virtual reality (VR) system are described. An analog circuit associated with the control device may include at least one amplifier and an analog-to-digital converter coupled to an amplifier by one or more electrical conductors. Electromagnetic interference induced in the one or more electrical conductors by an external AC magnetic field may be reduced using at least one component of the control device configured to reduce the electromagnetic interference.

Abstract: A thermoplastic interposer formed of ordered polymer sheets that may be configured to act as an interconnect and as a thermal energy spreader. In examples, the thermoplastic interposer may include one or more extensions or wings to further dissipate heat. In examples, laser direct structuring (LDS) may be used to form or more through silicon vias (TSVs) or through-chip vias. In examples, the ordered polymer sheets may be extruded via a roll-to-roll process, stacked, and processed to form a laminate interposer structure that makes up the interposer. In examples, the thermoplastic interposer may be used in multi-layer structures interconnecting two or more board assemblies such as printed circuit boards (PCB)s.

Abstract: An electronic device includes a substrate and a circuit having a plurality of electrically-conductive components disposed on the substrate. The plurality of electrically-conductive components includes first, second and third electrically-conductive components. The third electrically-conductive component has a first end portion forming a first interface with the first electrically-conductive component and a second end portion forming a second interface with the second electrically conductive component. The first electrically-conductive component is made of a first material including a first metal. The second electrically-conductive component is made of a second material including the first metal. The third electrically-conductive component is made of a third material including a gallium-based alloy and a metallic filler. The metallic filler reduces a reactivity of the third electrically-conductive component with the first metal at the first and second interfaces, and thus minimizes deterioration of the first electrically-conductive component and the second electrically-conductive component over time.

Abstract: A tunable lens including a pair of reflectors is disclosed. At least one of the reflectors may be curved for contributing to the focusing or defocusing power of the lens. At least one of the reflectors is translatable for tuning the focusing/defocusing power. The reflectors may be configured in a pancake lens configuration where one of the reflectors is a 50/50 reflector and the other is a polarization selective reflector. Refractive elements may be disposed between the reflectors for providing more optical power to the lens, and/or for balancing optical aberrations.

Abstract: An electronic device may include one or more terminals configured to provide a voltage signal to an actuator. The electronic device may detect a current associated with the voltage signal provided by the terminal to the actuator. The electronic device may determine an impedance across associated with the actuator based on the voltage signal and the electrical current. The electronic device may compare the impedance to a threshold impedance to determine whether there is sufficient skin contact with the actuator. The electronic device may provide audio via cartilage conduction if there is sufficient contact based on comparing the impedance to the threshold impedance, or may output a notification to the user to adjust placement of the electronic device to improve contact.
