Abstract: A method of switching a battery cell configuration for a head-worn extended-reality headset is described. The method includes, in accordance with a determination that a battery of the head-worn extended-reality headset is in a first state, operating at least two cells of the battery in series using a first control switch to produce a first voltage and, in accordance with a determination that the battery of the head-worn extended-reality headset is in a second state, operating the at least two cells of the battery in parallel using a second control switch to produce a second voltage, wherein the first and second voltages are within an operating voltage of the electrical components of the head-worn extended-reality headset. Switching the configuration in which the battery cells operate increases voltage headroom and decreases power losses by increasing the voltage of the battery cells and decreasing the current drawn by the battery cells.

Abstract: The disclosed computer-implemented method may include one or more multi-purpose connectors, one or more microfluidic devices, systems and methods for securing board-to-board connections, one or more embedded micro-coaxial wires in one or more rigid substrates, one or more miniature, micro-coaxial-to-board interconnect frogboards, and/or one or more artificial reality applications thereof. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: To address privacy issues with “always on” cameras of an AR headset, the cameras can be muted and content displayed by the headset adjusted to provide a user with a visual indication that the cameras are deactivated. The headset includes a display element configured to display content to a user and an eye tracking system that includes a camera configured to track eye motion of the user. In response to the headset receiving a camera muting event from the user or the external environment, the headset deactivates the camera and adjusts the content displayed on the display element to provide the user with a visual indication that the camera is deactivated. In one embodiment, the visual indication is an adjustment of the display from a default RGB color mode to “monochrome” or other predefined color map.

Abstract: The disclosed electronic shutter may include (1) an optical structure including a medium through which light from an environment passes to a lens of a camera for capturing an image of the environment; and (2) a controlling circuit that (a) detects a first condition of a signal, where the first condition indicates an activation of the camera, (b) controls, in response, to the first condition, the optical structure such that the medium attains a transparent optical state, (c) detects a second condition of the signal, where the second condition indicates a deactivation of the camera, and (d) controls, in response to the second condition, the optical structure such that the medium attains a non-transparent optical state in a manner that prevents visual detection of the lens from the environment. Various other methods and systems are also disclosed.
