Abstract: System and methods of providing automatic recording of a virtual meeting based on user activity is disclosed. The method includes determining if a virtual meeting has begun and if a user is available or attentive based on one or more sensors, including a webcam, a Bluetooth controller, an infrared camera, a proximity detector, and a microphone connected to the user device. When it is determined that the user is insufficiently available or attentive, a recording of the virtual meeting is started. A user attention status may be reassessed periodically, and the recording continues as long as the user remains insufficiently available or attentive. Once the user is determined to be available, the recording is ended.

Abstract: Described herein are systems and techniques for improving an accuracy of determinations made using data sensed in a wellbore or in a laboratory. Nuclear magnetic resonance (NMR) sensing devices may be used to collect data in a wellbore or lab. NMR sensing devices include a magnet (e.g., a permanent magnet or electromagnet) that provides a magnetic field that aligns the spins of protons in substances near the NMR sensing device. The magnetic field strength provided by the magnet of the NMR sensing device affects the sensitivity of the NMR sensing device and affects frequencies that the NMR sensing device effectively uses when the NMR sensing device operates. Systems and techniques of the present disclosure may measure concentrations of lithium in brine deposits when identifying particular brine deposits that include sufficient lithium concentrations to justify extracting lithium from those particular brine deposits.

Abstract: Systems and methods are provided herein for engaging navigation modes based on traffic events. For example, the disclosed system receives a request for navigating a user device from a start location to a final destination. The user device optionally indicates that turn-by-turn navigational directions are to be provided from an intermediate location to the final destination. The system determines all possible routes the user device can take from the start location to the intermediate location and, in some embodiments, from the intermediate location to the final destination. Once engaged, the system monitors the user device's progress from the start location to the intermediate location without displaying turn-by-turn navigation. During which time, the system notifies the user device of any traffic events that may impact the journey. When prompted, the system provides turn-by-turn navigational directions to bypass the traffic event.
