Abstract: Systems and method for controlling an electronic device using a worn wrist-wearable device are disclosed. A method includes detecting, by a wrist-wearable device worn by a user, an in-air gesture performed by the user. The wrist-wearable device is communicatively coupled with one or more electronic devices. The method includes, in response to a determination that the in-air gesture is associated with a control command (i) determining an electronic device of the one or more electronic devices to perform the control command, and (ii) providing instructions to the electronic device selected to perform the control command. The instructions cause the electronic device to perform the control command. The method further includes providing an indication via the wrist-wearable device and/or the one or more electronic devices that the control command was performed.

Abstract: A liquid crystal display panel for near-eye display comprises a liquid crystal (LC) panel and a backlight unit (BLU). The BLU includes an array of blue light-emitting diodes (LEDs) (1210); a light guide plate (1220) configured to guide the blue light from the array of blue LEDs (1210) through total internal reflection, and couple portions of the blue light guided by the light guide plate (1220) out of the light guide plate (1220); a quantum dot film (1230) including quantum dots configured to absorb blue light and emit red and green light; a brightness enhancement film (1250, 1260) configured to transmit incident light within an angular range and reflect incident light outside of the angular range; and an optical efficiency enhancement film (1240) configured to modify an angular beam profile of light from the quantum dot film (1230) such that the light transmitted by the brightness enhancement film (1260) has a peak intensity in a direction perpendicular to the LC panel.

Abstract: The disclosed extended-reality system may include (1) a power rail, (2) a load electrically coupled to the power rail, (3) a primary energy-storing element operable to provide power to the load via the power rail, (4) a bi-directional converter electrically coupled to the power rail, and (5) a secondary energy-storing element electrically coupled to the bi-directional converter and operable to (A) discharge by supplying power to the power rail through the bi-directional converter when a voltage of the power rail is at or below a discharging threshold value and (B) charge by extracting power from the power rail through the bi-directional converter when the voltage of the power rail is at or above a charging threshold value. Various other apparatus, methods, systems, and computer-readable media are also disclosed.

Abstract: A wearable device such as an augmented reality (AR) / virtual reality (VR) near-eye display device employs wireless communication technology to facilitate "walkie-talkie" style line-of-sight (LoS) communication between two users or one user and a group of users (unidirectional or bidirectional broadcast mode). The wireless communication may be facilitated by an ultra-wide band (UWB) or comparable wireless communication sub-system. The system may detect another user(s) within range of communication and within a predefined angle-of-arrival (AoA). The communication may be initiated by the user through an input allowing the user to communicate with the other user(s) discretely through audio and/or video modes. In a "walkie talkie selfie" mode, two or more users may capture images of each other, and the images may be superimposed generating a "selfie" of the entire group.
