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.

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: An apparatus may include a power rail, a subassembly, an additional subassembly, and an interface coupling the subassembly to the additional subassembly. The subassembly may include a load, an energy-storing component, a charger having an output coupled to the energy-storing component, and a reverse-current limiter having a first terminal coupled to the energy-storing component. The additional subassembly may include an additional energy-storing component, an additional charger having an output coupled to the additional energy-storing component, and an additional reverse-current limiter having a first terminal coupled to the additional energy-storing component. The power rail may cross the interface and may couple the load, an input of the charger, a second terminal of the reverse-current limiter, an input of the additional charger, and a second terminal of the additional reverse-current limiter. Various other apparatuses, systems, and methods are also disclosed.
