In some examples, a head-wearable apparatus for viewing augmented reality (AR) or virtual reality (VR) content is provided. An example the apparatus comprises a frame, an optical assembly including an image display in which the AR or VR content may be viewed by a user, and a user input device operable by the user to navigate through content viewed in the image display, or to invoke a function of the head-wearable apparatus. The user input device includes a body manually engageable by the user to perform a content navigation or function invocation operation and is configured to present at least one contact for accepting a connection to an external charging source, or a connection to an external device.

A mobile lighting system to integrate multiple power sources into a unified platform for portable, uninterrupted illumination. In various embodiments, the system includes a light source, an AC socket connector, internal rechargeable batteries, and external battery packs to thermally isolate high-temperature LED zones from power storage to reduce risk of thermal runaway. External interfaces include a USB Power Delivery port enabling bidirectional power transfer, dynamic role switching between source and sink, and data communication with mobile devices. Solar panel input may supplement charging. Intelligent switching logic, executed by stored instructions in a controller, manages transitions between AC, internal, and external power sources based on sensor-detected availability, charge levels, and user-defined priorities. Modular features include an on-device manual switch for on/off and dimming control, hot-swappable batteries, and real-time control and diagnostics through visual indicators or a connected application.

The present disclosure relates to a system and method to enable power negotiations between a Quick Charge (QC) power source with no USB power delivery (USBPD) support and a USBPD device. The proposed method identifies the support of USBPD and QC in the devices; determines the possibility of direct communication between the devices over either the D+/D lines or the CC lines, initiates the power negotiations between USBPD device and QC power source either by translating the USBPD messages on CC line to QC signalling on the D+/D lines and vice versa, or by handling the USBPD messages independently or combination of both; enable the fast charging of USBPD device till the maximum capacity of QC power source complying with USBPD and QC specifications.
